Description

The assay method of lithium isotope in fluid inclusion water in a kind of quartz vein of Porphyry-type Deposit
Technical field
The present invention relates to isotope field tests, say further, relate to the assay method of lithium isotope in fluid inclusion water in a kind of quartz vein of Porphyry-type Deposit.
Background technology
Porphyry copper is huge with it, and the even mineralising of total rock, buries shallow, and be suitable for exploitation, recovery rate in ore-dressing is high, becomes most important copper mine type in the world.In recent years, because of exposure in earth's surface, be easy to identify Porphyry-type Deposit be found more, reconnoitre the searching that need proceed to more blind deposit.Force people only can not be satisfied with descriptive one-tenth ore deposit-exploration model, start tectono-magmatic process (Richards et al., 2001 that on region-of-interest yardstick more, porphyry deposit is formed; , and the Deep Process that formed of mineralized porphyry and Geodynamic Background (Richards, 2003,2007 Richards, 2003); Hou et al., 2003,2004; Cooke et al., 2005); Meanwhile, (Ulrich et al., 2001 such as detailed evolutionary process and metallogenic material PRECIPITATION MECHANISM of BIFhosted gold deposit; Rusk et al., 2004; Redmond et al., 2004; Harris et al., 2005) emphasis studied especially.
BIFhosted gold deposit is most active geologic agent in mineralizing process, and in whole mineralizing process, it extracts, dissolve, carry, precipitate and have accumulated metallogenic material, is to link up ore source field, the medium of migration field and ore stockyard and tie (Zhai Yusheng, 1999).To develop closely-related Porphyry-type Deposit for mineralizing process and magmatic hydrotherm especially, carrying out detailed BIFhosted gold deposit research to it, contribute to reinventing magma-fluid-ore-forming evolution process, is the key of announcement origin of ore deposit.
The detailed evolutionary process of BIFhosted gold deposit and metallogenic material PRECIPITATION MECHANISM etc. are all the most important things of mineral deposit research all the time.BIFhosted gold deposit is mineral deposit, especially hydrothermal deposit main medium when being formed, and plays an important role in the activation of mineral, migration and precipitation process.It is generally acknowledged, dissimilar hydrothermal deposit, its BIFhosted gold deposit source is not quite similar; Therefore, finding out that the source of BIFhosted gold deposit is for understanding mineralization in depth, finding out that water-filling conditions tool is of great significance.Usually, when hydroxyl altered mineral (as hornblende, chlorite, mica mineral) is grown in a large number, we can by measuring this type of mineral Hydrogen-oxygen Isotope composition (White, 1974), and utilize respective isotope fractionation equation, converse the Hydrogen-oxygen Isotope composition of BIFhosted gold deposit during mineral formation, be used for the source of spike BIFhosted gold deposit and Evolution Paths (as Sheppard andGustafson, 1975; Harris et al., 2005).But when the agensis of hydroxyl altered mineral or less growth, people, usually through the Determination of Oxygen Isotopes containing oxygen gangue mineral, converse the oxygen isotope of BIFhosted gold deposit during mineral formation; By the direct mensuration of this type of mineral inner fluid inclusion hydrogen isotope, investigate thoroughly the hydrogen isotope composition of BIFhosted gold deposit.
As gangue mineral the most common in hydrothermal deposit, quartz, with its metastable feature, makes its benefit extensive concern in ore-forming source.Usually, conventional BrF is adopted 5method measures quartzy oxygen isotope composition, and hydrogen isotope then uses decrepitation method to get inclusion water, the hydrogen manufacturing of zinc method, result mass spectroscopy.The quartzy oxygen isotope composition δ finally obtained 18o quartz, the OXYGEN ISOTOPE FRACTIONATION equation 1000ln α of the quartz-water utilizing Clavton to recommend quartz-water=δ 18o quartz-δ 18o water=3.38*10 6t -2the experience Fractionation Equations that the quartz that-3.40 (200-500 DEG C) (Clavton et al., 1972) or Zhang Ligang provide-water equilibrium oxygen isotope exchanges: 1000ln α quartz-water=δ 18o quartz-δ 18o water=3.42*10 6t -2-2.86 (Zhang Ligang, 1985), are calculated to be and exchange BIFhosted gold deposit oxygen isotope when reaching balance with mineral isotope and form δ 18o water, its result is thrown at δ D-δ together with fluid inclusion hydrogen isotope 18o waterin diagram (Zheng Yongfei, 2000), to judge the source of BIFhosted gold deposit.
These ways have it to be difficult to the defect avoided above.Quartz decrepitation method gets inclusion water to obtain hydrogen isotope composition: be 1. difficult to avoid second inclusion to mix (Yang Zhiming, 2009); 2. the explosive spalling isotope fractionation that may cause, Faure (2003) obtains conclusion through experiment: same quartz specimen burst at 800 DEG C extract water than 500 DEG C at the δ D of explosion extraction aquametry h2Olow by 10 ~ 15 ‰, clearly explosive spalling can cause hydrogen isotope fractionation, can not represent into the isotopics of fluid during ore deposit, and separately have document (Sheetset al., 1996; O'Reilly et al., 1997; Gleeson et al., 1999; Barker et al., 2000) show the δ D that more than the 1000 DEG C Quartz inclusion extraction water burst obtain h2Oit is unusual low value; 3. inclusion opens the pollution that may cause; These all can make hydrogen isotope composition be affected.
For traditional stable isotope (as C, H and O), lithium isotope is a kind of unconventional stable isotope.Lithium isotope geochemistry is the research field (Zhang Hongfu etc., 2007) that international ground educational circles is emerging in recent years.The Geochemical Properties that lithium has many uniquenesses makes it in the various geologic function that spike is relevant with fluid, demonstrate special superiority
It is the mineral that mica mineral, spodumene, hornblende etc. lithium content is higher that lithium isotope measures current conventional mineral, quartz due to the low and indissoluble solution of lithium content, less use.But Just because of this, quartz has fabulous physical chemistry patience, therefore often can not with its physicochemical property of environment change, therefore, the isotopics in the quartz that same period is not secondary in fluid inclusion water can reflect the not time BIFhosted gold deposit isotopics same period
Study BIFhosted gold deposit by lithium isotope, the lithium isotope in fluid inclusion water measures can obtain direct result.But in hydrothermal deposit to become the relevant quartz vein in ore deposit mostly tiny, and comprise in quartz vein that fluid inclusion quantity is few, volume is little, the fluid inclusion water extracted is difficult to satisfiedly test needs.It is the mineral that mica mineral, spodumene, hornblende etc. lithium content is higher that lithium isotope measures current conventional mineral, and quartz is due to lithium content low and indissoluble solution, also less use.Therefore, in the urgent need to the pre-treating method setting up a quartz specimen, quartz and fluid inclusion are separated, and set up an experimental formula, by the lithium isotope (δ of quartz 7li quartz) and fluid inclusions homogenization temperature (T homogeneous) Accurate Determining, lithium isotope composition (δ can be obtained in fluid inclusion water 7li fluid).
