Abstract

This study introduced the development process, research status, and application effects of the tectono-geochemistry survey theory, and proposed the tectono-geochemistry weak information extraction method by summarizing the latest research results and understandings based on the prospecting practice in bedrock areas. Based on the contrastive analysis, this study pointed out the limitations of the conventional geochemical survey methods and the advantages of the tectono-geochemistry weak information extraction method, which was developed from the conventional tectono-geochemistry survey method. Moreover, this study systematically summarized the theoretical basis, operating conditions, deployment method, sampling principle, sampling media, anomaly interpretation, mapping, and application of the tectono-geochemistry weak information extraction method, highlighting the rationality of the deployment method, the representativeness of sampling points, the diversity of sampling media, and the validity (“yes” and “no”) of element anomalies and samples. Based on these, this study established the index system of this method. Finally, by combining the prospecting prediction of the eastern section of the Huijiabao anticline in the distribution area of Carlin-type gold deposits in southwestern Guizhou, this study concluded that the tectono-geochemistry weak information extraction method can extract the deep metallogenic weak information more effectively than the conventional tectono-geochemistry survey. It also inferred that this method has a good application prospect in the prospecting of concealed hydrothermal deposits and can be applied to the prospecting prediction of concealed hydrothermal deposits in all bedrock areas.

Key words： bedrock area hydrothermal deposit prospecting prediction tectono-geochemistry weak information extraction
