Method for rapidly delineating gold mine prospecting target area

Abstract

The invention belongs to the technical field of geological science, and particularly discloses a method for quickly delineating a gold mine prospecting target area. The method can be used for predicting a gold mine in an area with a relatively low working degree. The method comprises the following steps: firstly, dividing a metallogenic system, selecting a typical ore deposit, and then establishing a typical ore deposit metallogenic mode and a typical ore deposit prospecting mode; establishing a metallogenic system metallogenic mode according to the metallogenic system, and extracting an abnormal series; establishing a metallogenic system prospecting model according to the results, and determining metallogenic geological necessary conditions according to the metallogenic action on the basis of the metallogenic system prospecting model; calculating an Au prediction anomaly lower limit, and carrying out geochemical anomaly delineation; preliminarily delineating a prediction target region according to the metallogenic geological necessary conditions and the geochemical anomaly delineating result; according to the preliminarily delineated prediction target area, compiling a prospecting prediction map on the basis of the gold mine prediction basic map; and determining a key target finding area and a general target prospecting area according to the prospecting prediction map, performing field inspection verification in the key target finding area, and evaluating the prospecting prospect according to the verification result.

Description

technical field [0001] The invention relates to the field of geological science and technology, and more specifically relates to a method for quickly delineating a gold ore prospecting target area. Background technique [0002] Mineralization is a very complex system, which will generate a large amount of metallogenic information. When predicting mineralization, we usually start with geology, physics, chemistry, remoteness, etc., and select dozens or even nearly a hundred pieces of information (variable ) for research, calculation, and analysis, and strive not to miss any information. However, in metallogenic prediction, it is extremely difficult to obtain information in areas with a very low degree of work, which makes metallogenic prediction very difficult. [0003] The study of gold deposits mainly began after the 1990s, and in most cases, with the discovery of ore deposits, the research on ore-forming conditions, ore-forming characteristics, ore-controlling factors, ore...

AI Technical Summary

Problems solved by technology

Most of this kind of research is the study of a single deposit, and focuses on production and application. The research on metallogenic structure and metallogenic model is still relatively weak. In-depth research, the regional metallogenic law still needs to be deeply understood, and the research on ore prospecting prediction is relatively weak

[0004]In recent years, prediction theories such as "similar analogy", "geological anomaly", "genetic model of ore deposit" or "mineralization system" have been widely used, but due to the Due to the complexity of ore processes, the characteristics and signs of gold deposits are not completely consistent, and the required technical methods are not uniform, and the prediction of gold deposits by a single prediction method is also very limited.
