Description
Technical Field
The invention belongs to the technical field of detection of cinnabar-containing quartz seal stones, and particularly relates to a method for judging the production area of cinnabar-containing quartz seal stones based on Raman spectrum.
Background
The henxueshi stone is a precious jade which is mainly distributed in the inner Mongolia Balin China and Zhejiang Changhui areas, and is commonly worn and collected by artists as ornaments or stamps such as pendants, ornaments and the like, wherein the stamps are particularly famous in the sea and at the outside and the sea and are vegetarian with the reputation of 'inkstone queen'. Due to extensive and disordered mining over a long period of time, the mineral resources of the chicken blood stones are gradually reduced. Furthermore, with the gradual depletion of the mineral resources of the chicken bloodstone, a plurality of similar varieties of the chicken bloodstone appear on the market. Therefore, the identification of the chicken bloodstone and similar products and the quality grade evaluation of the chicken bloodstone are gradually concerned by jewelry quality inspection, materials and geological researchers.
According to the current QB/T4183 classification of chicken blood stone products and GB/T16553 appraisal of jewelry jade, the chicken blood stone is divided into three major categories of frozen/soft ground (the main body is dickite), hard ground (the main body is alunite) and hard ground (quartz) again according to the main mineral composition of ground (excluding cinnabar part). In terms of the chicken bloodstone which is currently sold and circulated, the barren chicken bloodstone is basically frozen and soft ground chicken bloodstone, namely the ground is composed of dickite. The above three major products are seen in the bleeding stones transformed from Zhejiang Chang, and the yield is quite abundant, and the bleeding stones are widely distributed in the market, wherein the bleeding stones mainly transform into hard bleeding stones from Chang.
Aiming at the research of changhua hard land chicken bloodstone and similar variety 'chicken bloodstone', people develop: zhou Wubang [1] And testing the main mineral composition, characteristics and chemical components by using methods such as a polarizing microscope, X-ray powder diffraction, an electronic probe and the like, and researching the mineralogical characteristic difference of the changcheng hematite and similar varieties thereof. Mainly for the comparison of the formation period, distribution, crystal structure and element composition of blood. Under the assistance of various technologies, the chicken can be distinguished from the changcheng hard chickenGems similar to bloodstones.
Further, chen Qian [2] And researching the mineralogy and spectral characteristics of similar varieties of the haematite by using an X-ray powder crystal diffractometer, a scanning electron microscope, an infrared spectrometer and a Raman spectrometer. The research result shows that: the 'blood' of similar species of the chicken bloodstone is cinnabar, and the main constituent minerals are quartz and carbonate minerals. This study has considerable significance for identifying the origin of "hensha" and "hengshi" which are quartz.
The researchers all start from the characteristic part in the similar variety of the chicken bloodstone, and jointly identify the producing areas of the similar variety of the chicken bloodstone by multiple technologies. However, in terms of detection means, the provided research scheme has a plurality of technologies, the loss of the gem to a certain degree exists in X-ray powder diffraction and infrared powder transmission spectrum tests, and the analysis of the X-ray powder diffraction result cannot deduce the result in a short time because of a plurality of phases.

Disclosure of Invention
The invention provides a method for judging the origin of a quartz seal stone containing cinnabar based on Raman spectrum, aiming at overcoming the defects that a plurality of technologies are needed to be combined and complicated atlas analysis is needed to judge the seal stone with blood and ground quartz and the loss exists in the test process.
In order to achieve the purpose, the invention is realized by the following technical scheme:
a method for judging the origin of a quartz seal stone containing cinnabar based on Raman spectrum comprises the following steps:
s1, performing Raman spectrum test on a red area of a sample to be detected, judging whether a cinnabar characteristic peak appears according to a test result, and judging whether the sample is cinnabar-containing substances.
The Raman spectrometer used in the invention is also provided with an optical microscopic image system.
And S2, performing Raman spectrum test on a non-red area of the sample according to the detection result of the S1, judging whether a quartz characteristic peak appears according to the test result, and judging whether the composition of the main minerals of the sample is quartz or not.
The apparent appearance of the quartz stamp stone containing cinnabar is observed by naked eyes, and the surface of the quartz stamp stone can be clearly divided into a red area part and a non-red area part. The red area can be divided into light red, red and dark red areas according to the change of the color depth. The quartz seal stones containing cinnabar in different producing areas are different in color and luster and color distribution; therefore, in the process of performing the raman test, attention should be paid to scanning the surface of the sample in each area in order to obtain a more accurate determination result of the production place.
And S3, displaying a sample with quartz formed by the main minerals according to the detection result in the S2, performing Raman spectrum test on the characteristic region in the non-red region of the sample again, judging whether a characteristic peak corresponding to the impurity minerals appears according to the test result, and determining the quartz seal stone production place containing cinnabar.
The characteristic regions in the non-red region refer to regions where the flat signet stone sheet shows different optical characteristics in the optical microscopic image system in the raman spectrum test, and these regions show special-shaped tiny particles or colored regions in the optical microscopic image system. And further performing Raman spectrum test on the characteristic regions, detecting mineral impurities in the characteristic regions, and determining the origin of the quartz seal stone containing cinnabar.
The applicant of the invention finds that the origin of the quartzite containing cinnabar can be determined by detecting impurity minerals in the Dan Yingzhi cinnabar containing cinnabar. In the past, the origin and the place of production were usually determined by detecting the components and distribution patterns of the "ground" and "blood" in quartz signet stones containing cinnabar. Secondly, the instrument related by the invention is only Raman spectrum, and the signet stone sample does not need to be subjected to related pretreatment in the Raman spectrum test, so that the gem cannot be lost. Moreover, the invention develops a new method, and detects the impurity minerals in Dan Yingzhi seal stone containing cinnabar; in the analysis of test results, the characteristic peaks of the minerals detected by the Raman spectrum are clear, and the method is not a professionally qualified professional in the industry, and can easily determine the producing area based on the characteristic peak results analyzed by the method.
More specifically, 252. + -. 2 cm appears when the red region is tested by Raman spectroscopy -1 、286±2 cm -1 And
343±2 cm -1 the characteristic peak of the position can be determined as the signet stone containing cinnabar. On the basis, 126 +/-2 cm appears when the non-red area is tested by using the Raman spectrum again -1 、206±2 cm -1 、263±2 cm -1 、354±2 cm -1 、463±2 cm -1 And 808 +/-2 cm -1 The characteristic peak of the ink can be determined as the quartz seal stone containing cinnabar. Finally, on the basis, the production place attribution of the quartz seal stone containing cinnabar can be finally determined by testing the characteristic region by using the Raman spectrum: 1) When one or more of alunite, dickite, zircon, rutile and anatase characteristic peaks appear in the spectrum, the producing area can be determined to be Zhejiang Changchang; 2) When a characteristic peak of pyrite appears in the spectrum, or when characteristic peaks of dolomite and calcite simultaneously appear in the spectrum, the producing area can be determined to be Guangxi minium; 3) When the characteristic peak of dolomite appears in the spectrum, the origin can be determined to be Shaanxi.
Preferably, the characteristic peak of cinnabar in step S1 is 252 +/-2 cm -1 、286±2 cm -1 And 343. + -. 2 cm -1 Characteristic peak of (c).
When 252 + -2 cm appear in the Raman spectrum at the same time -1 、286±2 cm -1 And 343 + -2 cm -1 And determining that the sample to be detected contains cinnabar when the characteristic peak is detected. This is similar to the way "blood" is judged in general test means. If no corresponding characteristic peak appears, the non-cinnabar chromogenic substance is determined, and the judgment of the substance is not in the technical scheme of the invention.
Preferably, the characteristic peak of quartz in the step S2 is 126 +/-2 cm -1 、206±2 cm -1 、263±2 cm -1 、354±2 cm -1 、463±2 cm -1 And 808 +/-2 cm -1 Characteristic peak of (c).
When 126 +/-2 cm appear in Raman spectrum at the same time -1 、206±2 cm -1 、263±2 cm -1 、354±2 cm -1 、
463±2 cm -1 And 808 +/-2 cm -1 When the characteristic peak is detected, the quartz in the sample to be detected can be determined. If the corresponding characteristic peak does not appear, the main body composition of the sample is judged to be non-quartz, and the judgment of the substances is not in the technical scheme of the invention.
Preferably, when the characteristic peaks of the impurity minerals obtained in the step S3 are one or more of alunite, dickite, zircon, rutile and anatase characteristic peaks, the producing area can be determined to be Zhejiang Changchang.
According to the definition of the attributes of the existing QB/T4183 Classification of chicken bloodstone products, GB/T16552 Jewelry Jade name and GB/T16553 Gerbry Jade identification, the sample is actually the quartz chicken bloodstone produced in the areas of Zhejiang Chang.
Preferably, the main mineral of the raman spectrum in step S2 further includes graphite, and the impurity mineral characteristic peak obtained in step S3 is a characteristic peak of pyrite, and the producing area can be determined to be south-west-south-lead.
By observing the above-mentioned southern Guangxi Dan habitat samples with naked eyes, it can be found that: the red (light red, red and dark red) regions of the sample, i.e. the cinnabar-containing regions, are present in the non-red mineral matrix in lamellar form, and the non-red regions are overall in a grey-black or black color.
Preferably, the characteristic peaks of the impurity minerals obtained in the step S3 are dolomite characteristic peaks, and the producing area can be determined to be shanxi.
By observing the Shanxi province samples with naked eyes, the following can be found: the red (light red, red and dark red) areas of the sample, i.e. the cinnabar-containing areas, are randomly distributed or present in a non-red mineral matrix. In addition, shaanxi producing areas, which are quartz-based signets containing cinnabar, can be classified into Shaanxi xi Shaanxi and Shaanxi Laiyyang.
Preferably, the characteristic peaks of the impurity minerals obtained in the step S3 are dolomite and calcite characteristic peaks, and the producing area can be determined to be Guangxi minium.
By observing the above-mentioned southern Guangxi Dan habitat samples with naked eyes, it can be found that: the red (light red, red and dark red) areas of the sample, i.e. the cinnabar-containing areas, are randomly distributed or present in the non-red mineral matrix, and the non-red areas appear grey-black overall.
Preferably, the excitation wavelength in the raman spectroscopic test is 532 nm.
Commonly used raman spectral excitation wavelengths are 325 nm, 405 nm, 532 nm, 785 nm, and the like. The applicant of the present invention finds that under the excitation wavelength of 325 nm, 405 nm or 785 nm, some substance characteristic peaks in the technical scheme of the present invention cannot be completely shown, and are not favorable for accurately determining the production area of the quartz seal stone containing cinnabar. For example, at the excitation wavelength of 325 nm, the characteristic peak of cinnabar cannot be well represented; and under the excitation wavelength of 785 nm, OH characteristic peaks in structural characteristics of dickite and the like cannot be completely presented, so that the spectrum identification is influenced to a certain extent, and the workload is increased. Therefore, in the present invention, 532 nm is preferable as the excitation wavelength of the raman spectrum.
Preferably, the collection range of the Raman spectroscopy test is 100-4000 cm -1 。
Preferably, in the raman spectroscopy detection process, the collection points should be uniformly distributed on the surface of the sample.
In order to judge the origin as accurately as possible, in the raman detection process, a plurality of collection points are selected on the surface of a sample to be detected, and the collection points are uniformly distributed on the surface of the sample and come from each area of the sample.
In addition, the laser intensity is preferably not to ablate the quartz signet stone sample containing cinnabar during the test. The quartz seal stones containing cinnabar in different producing areas have different sensitivity degrees to laser. When information is collected, if the energy is too small, the sample information cannot be reflected well. It is not suitable to use a uniform amount of laser energy for all samples.
It is worth noting that cinnabar of all the samples is naturally enriched in the 'ground' in the geological mineralization process, but not existed in the substrate, namely the 'ground', in the modes of post-artificial treatment, injection and the like.
Therefore, the present invention has the following advantageous effects:
(1) The invention can determine the quartz seal stone containing cinnabar by adopting a single Raman spectrum technology, has simple data analysis and is easy to widely learn and spread;
(2) The method adopts the Raman spectrum technology to test characteristic peaks of various substances, does not need to take blocks of the seal stone to grind and then carry out slice test, and can directly collect the test on the surface of the seal stone, thereby avoiding the loss in the test, protecting the original seal stone to the maximum extent and meeting the requirement of nondestructive test on jewelry;
(3) The method summarizes specific impurity mineral characteristic peaks corresponding to various producing areas of the quartz seal stone containing cinnabar, and can provide technical support for judging and tracing the later producing areas;
(4) The method for judging the origin tracing of the quartz seal stone containing cinnabar by utilizing the Raman spectrum has the characteristics of accuracy, no damage and rapidness, and can provide universal and convenient directive identification basis for the qualitative judgment of the origin of the quartz seal stone containing cinnabar.
