Description
Technical Field
The invention relates to the technical field of ore deposit exploration, in particular to a method for rapidly delineating porphyry ore deposit ore bodies by utilizing the content of chlorite trace elements.
Background
With the continuous development of world economy, mineral resources on the earth surface are increasingly exhausted, and the depth of mineral exploration is deeper and deeper. However, for covered-area ore deposits, particularly deep blind ore deposits, the traditional chemical exploration method has limited effect, and the geophysical exploration method often has multiple resolvability, so that the current ore exploration work faces huge challenges. Therefore, there is an urgent need for more efficient methods to improve the accuracy of concealed ore body exploration and thus establish efficient mineral exploration markers. The altered mineral is a key object and an important means for researching the cause of the hydrothermal deposit and guiding the prospecting, and the system combs the type, combination, spatial distribution characteristic and physical and chemical standard type characteristic of the altered mineral in the deposit area, so that the understanding of the cause mechanism of the deposit and the improvement of the prospecting efficiency are facilitated. The porphyry deposit has the characteristics of easy open-pit mining, low grade, large scale, uniform mineralization and the like, has very important economic value, provides nearly 75 percent of copper, 50 percent of molybdenum and 20 percent of gold and small amount of other metals such as silver, zinc, lead, bismuth and the like in the world, and is the most important copper ore type in the world. The green pan rock alteration zone is arranged at the periphery of the porphyry deposit, chlorite generally develops, commonly coexists with minerals such as green curtain stone, calcite and quartz, and has close relation with the mineralization process.
Chlorite is an important hydrothermal alteration mineral, is an important carrier for recording hydrothermal processes of mineral deposits, has important significance for indicating the cause of the mineral deposits, and therefore, the research on chemical components and structural characteristics of chlorite is always valued by experts and scholars at home and abroad. However, previous studies on chlorite have focused mainly on its chemical composition and structural characteristics, and chlorite characteristics, particularly trace elements, have not been used as a mineral exploration method for judging the mineralization center of porphyry mineral deposits. In addition, chlorite often contains other mineral inclusions and forms a complex symbiotic relationship with other minerals, interfering with the task of mineral exploration with the chlorite component.
In the prior art, a raman spectrum and electronic probe data are used for researching chlorite to identify a porphyry ore deposit hydrothermal center, but regarding chlorite elements, the research is only the main quantity element data of the chlorite, but the main quantity element data of the chlorite generally has a smaller variation range and is easily influenced by surrounding rock components; most importantly, the method identifies the hydrothermal center of the porphyry deposit mainly by qualitative description and not quantitative; in addition, other mineral inclusions are often included in the chlorite data, which affect the chlorite data and also affect the accuracy of the survey method using the chlorite data.
In view of the above, the present invention is particularly proposed.
