High-altitude permafrost region porphyry type copper polymetallic mine exploration technology combination method

Abstract

The invention discloses a high-altitude permafrost region porphyry type copper polymetallic mine exploration technology combination method which can improve the prospecting success rate. The method includes the following steps: A, determining a metallogenic system as a collision orogenic metallogenic system in cooperation with a collision orogenic regional geological background according to the output spatial-temporal characteristics of a permafrost region porphyry type copper molybdenum mine typical mineral deposit and numerous mineral occurrences; B, measuring stream sediments with the aim of observing geochemical halos on the upper portion of a porphyry body mineral body, defining a magnetic abnormity region through high-accuracy magnetic measurement, and defining a remote sensing predicting region with the aim of forecasting mineral resources such as copper, lead and zinc through high resolution remote sensing; C, conducting 1:1 soil profile or petrochemistry profile, groove and well exploratory exposure on explored abnormal or mineralization clues; D, defining a mineralized region or the mineral body; E, verifying the defined mineralized region or mineral body through drilling; F, determining the mineral body or the mineral deposit. By means of the method, the prospecting working period of a porphyry type copper molybdenum mineral region can be shortened, and meanwhile numerous metal mineral bodies can be explored.

Description

technical field [0001] The invention relates to an ore prospecting method, in particular to a combined method for prospecting porphyry copper-polymetallic ore in high-altitude permafrost regions. Background technique [0002] Known: A combined method for the exploration of porphyry-type copper-polymetallic deposits in the permafrost region of the Qinghai-Tibet Plateau Controlled by the contact zone of the porphyry, the ore bodies are distributed along the upper part of the porphyry body close to the contact zone, and the strength of mineralization is closely related to the degree of fractures between the rock mass and the surrounding rock. [0003] The ore-forming geological background, ore-bearing regularity, ore-controlling elements, and ore body characteristics of porphyry-type copper-molybdenum deposits in high-altitude permafrost areas are different from those in other areas, such as conventional soil measurement, transient electromagnetic, and low-resolution remote sen...
