Cataclastic lithoface determination method

Abstract

The invention relates to a cataclastic lithoface determination method. The method specifically comprises the steps of 1) carrying out field structure petrographic reconnaissance; 2) carrying out fieldmacroscopic structure measurement; 3) measuring and counting the crack attitude of cataclastic lithofacies of all strength and levels; 4) systematically collecting all kinds of specimens; 5) making various sheets, polished sheets and probe sheets, and carrying out petrographic and mineralographic identification under a polarizing microscope; 6) carrying out microscopic crack measurement and statistics on the basis of the petrographic and mineralographic identification; 7) carrying out microscopic crack petrographic and geochemical petrographic research; and 8) delineating the cataclastic lithofacies. The method disclosed by the invention has the following advantages: the quantitative description of cataclastic lithoface characteristics and classification is realized; the theoretical research and the application analysis are combined; and basic data is provided for analyzing a rock and ore forming mechanism and a coupling mechanism of a structure and a fluid, carrying out ore prospecting prediction, evaluating distribution rules of hydrogeologic water and the slope stability of circulating and engineering geology, assessing environmental geological disasters and the like.

Description

technical field [0001] The invention relates to the technical field of mineral exploration, the technical field of ecological environment and the technical field of geological disasters, and specifically refers to a method for determining a catabolic phase. Background technique [0002] Catalite facies are widely developed in the brittle structural deformation domain of the shallow crust. Catalite facies are formed in the process of crustal reformation. They have the characteristics of strong coupling between fractures and fluids, and are closely related to people's life and production. In the field of geological exploration, small structures such as fractures, joints, lamellae, and lines are favorable ore liquid migration channels and storage spaces, and are also important components of catatolitic facies, which can effectively identify cataclazed facies and their composition It is an important research content of ore prospecting prediction. In the fields of hydrogeology, ...

AI Technical Summary

Problems solved by technology

Nowadays, most of the production and research focus on the detection of cataclysmic rock mass by using geophysical prospecting methods, which cannot meet the requirements for the identification of cataclititic facies, and lack of comprehensive, systematic and fine identification and determination technology for cataclazic facies.
