Embodiment

[0031] In this embodiment, the Dagu Gongka copper (molybdenum) mine located in the north-west section of the Narigongma area is selected as an example, and the prospecting effect of this combination of exploration techniques and methods is briefly described. figure 1 This is the technical flow chart of this embodiment;

[0032] 1. From the perspective of metallogenic system, understand the source and ore-controlling factors of magmatic copper-polymetallic metallogenic materials:

[0033] The Dagu Gongka polymetallic mine is located in the northwest section of the Narigongma slurry-type copper-molybdenum polymetallic mining area. It has similarities in regional geological background, structural geological characteristics, outcropping strata, intrusive rock mass and ore-controlling elements. Its metallogenic system is also similar to that of the Narigongma slurry-type copper-molybdenum deposit.

Abstract

The invention discloses a cenozoic magmatic copper polymetallic ore prospecting method. The method comprises the following steps: determining a magmatic zone or an abnormal area (zone) according to magmatic ore deposit and spot output space-time and geological background; preliminarily determining prospecting targets and target classification by virtue of stream sediment measurement; selecting zones having excellent copper mineralization or molybdenum mineralization or excellent abnormality in target classification for performing magnetic survey verification, and determining a first precedencetarget area or a first abnormal area; determining a second precedence target area or a second abnormal area in the first precedence target area or the first abnormal area by adopting high resolutionremote sensing; performing on-the-spot survey inspection on the second precedence target area or the second abnormal area, and finding out a geologic abnormal area (zone) or a mineralization clue area; performing soil profile or petrochemical profile measurement according to 1:10000, and determining the ore-bearing geological body position on the surface and mineralized body features; performing shallow exposure recourse to control the specific location and shape of the mineralized zone or mineralized body by utilizing trenching; and determining the depth grade thickness scale and occurrence conditions of the mineralized body by utilizing drilling, and discovering the metal ore or ore deposit.

Description

technical field [0001] The invention relates to the technical field of geology, in particular to a prospecting method for Cenozoic magma-type copper-polymetallic ore. Background technique [0002] The prospecting method refers to the general term for the working methods and technical measures adopted in order to find ore deposits. Prospecting is the geological and mineral work carried out in a certain area to find and evaluate the minerals needed by the national economy. , for the purpose of discovering various mineral prospecting work, discovering ore points, mineralized areas or ore deposits, and conducting preliminary geological and economic evaluation (industrial prospect evaluation) of them. Its tasks include: researching the geological structure of the working area, especially related to the formation of minerals. Geological conditions that are closely related to distribution, predict favorable areas where there may be minerals: comprehensively use effective technical...
