3 General
3.1 Rock geochemical survey is a geochemical exploration of rock as a sampling medium, mainly used in regional geochemical exploration and back.
Landscape research, geochemical exploration of metallogenic belts, geochemical exploration of mining areas, and research on the genesis of deposits. Regional Earth
Chemical exploration, geochemical surveys, geochemical surveys in geochemical surveys, and special surveys of rock geochemistry.
3.2 The main task of rock geochemical survey in regional geochemical exploration is to identify the distribution and distribution characteristics of elements in regional rocks.
The background and anomaly of the geochemical region of the rock provide a basis for the interpretation of regional geochemical anomalies.
3.3 Rock geochemical surveys in geochemical surveys are generally found in the anomalous zones discovered by regional geochemical exploration, or in the division of geological mineral surveys.
The prospect of the mine prospecting area is to delineate the anomalous concentration sites, perform anomaly screening based on the typical characteristics of typical deposits, and determine the prospecting target area.
The certificate has an abnormality in the meaning of prospecting.
3.4 The geochemical survey of rocks in the detailed survey of geochemistry is mainly aimed at prospecting target areas and deep mineral exploration. The main task is to confirm
Determine the degree of denudation and ore-forming depth of the prospecting target area based on the ore-forming geochemical zoning characteristics of the typical ore deposit.
Quantitative prediction of resources and reserve estimates provide a basis for implementing deep engineering verification.
3.5 Special surveys of rock geochemistry include typical deposit research, resource potential assessment, and special rock geochemical measurements. Typical deposit
In this respect, we mainly study the diagenetic-metallogenic-forming halo geochemical processes of various deposit types, and study the genetic mechanism, age and formation environment of the deposits.
The anomalous characteristics and zoning laws of ore-forming elements establish a prospecting geochemical model and guide geological prospecting.
