Methods of common identification and evaluation method based on geological connotation -based connotation

Abstract

The invention relates to a geochemical exploration anomaly recognizing and evaluating method based on contents contained in geology. The method includes the steps of acquiring original data, calculating a background value of each geological unit, processing the original data in a grid mode, calculating liner value grid data, calculating mineralization intensity anomaly value grid data, calculating deposit type anomaly value grid data and drawing a mineralization intensity anomaly chart and a deposit type anomaly chart. Anomaly recognizing and anomaly evaluating are integrated, and the problem that with a traditional processing method, element chemical properties, redox environments, weathering denudation and many other factors have influences on anomaly screening and evaluating is solved. Interference of solution multiplicity, uncertainty and objective judgment is greatly reduced, therefore, the anomaly having important prospecting value shows obvious regularity, geochemical exploration anomaly recognizing and evaluating efficiency is obviously improved, and the method is particularly applicable to processing regional mass geochemical exploration data. A whole processing technology capable of achieving computer programming is provided.

Description

technical field [0001] The invention belongs to the technical field of geochemical information processing. By processing massive regional geochemical prospecting data, the data is objectively endowed with geological connotations to delineate the "mineralization type" anomalous map and "mineralization intensity" anomalous map with specific geological features. Anomalous map of significance, so as to quickly screen and evaluate a new method of anomaly related to mineralization, and provide a set of processing techniques that can be implemented by computer programming. Background technique [0002] Since the beginning of the new century, science and information technology have been constantly changing, and the current research content of geochemical data processing technology has attracted increasing attention from some major mining countries in the world. In the past 10 years, relevant basic research and metallogenic prediction work have been carried out. Geochemical data proc...

Problems solved by technology

[0011] Generally speaking, the existing geochemical data processing methods and geochemical data processing software are mainly based on the characteristics of the data itself, various parameters and data structure analysis. There are subjectivity and multi-interpretation in terms of the influence of metallization, and it is very difficult to quickly delineate and screen large-scale anomalies related to mineralization. At the same time, there is no corresponding set of software processing procedures for quick and easy processing and delineation.
