天津地区成矿地质特征及时空演化规律
Geological Characteristics of Mineralization and the Spatial-Temporal Evolution Regularity in the Tianjin Area
摘要
Abstract
The geological conditions for mineralization in Tianjin are complex,which have given rise to abundant mineral re-sources.Among them,the development and utilization of mineral resources,such as oil,natural gas,and geothermal resources,are of significant national importance.This article,based on research and compilation in China Mineral Geology:Tianjin Vol-ume,systematically summarizes the achievements of over a century of mineral resource exploration in Tianjin City and out-lines the general characteristics of its mineral resources,with an emphasis on its superior and distinctive mineral types.For the first time,a three-tier classification system for mineral deposit types(genetic/industrial)covering all mineral species in Tianjin City has been established.The metallogenic geological characteristics of various minerals are summarized from four as-pects:sedimentary metallogeny,magmatic metallogeny,metamorphic metallogeny,and epigenetic metallogeny.Guided by the theory of mineralization series,a study on the metallogenic regularity of the entire region was conducted.This led to the divi-sion of Tianjin City into Ⅲ-57 and Ⅲ-62,with 2 Level-Ⅲ metallogenic belts,6 Level-Ⅳ metallogenic sub-belts,and 4 Level-Ⅴ ore concentration areas.Analyzed and summarized the evolutionary pattern of mineral resources in the city from both spatial and temporal perspectives.This achievement is a milestone in mineral geology in Tianjin City,deepening and elevating the study of metallogenic regularity and providing important guidance for future mineral exploration.关键词
