| 中文摘要: |
| 天津地区成矿地质条件复杂，孕育了丰富的矿产资源，其中石油、天然气、地热等矿产资源的开发利用在全国占有重要地位。本文以《中国矿产地质志·天津卷》研编工作为基础，系统总结了百余年来天津市矿产资源勘查成果、矿产资源总体特征，突出了优势和特色矿种；首次建立了天津市矿种全覆盖的矿床（成因/工业）类型三级分类体系，从沉积成矿作用、岩浆成矿作用、含矿流体成矿作用、变质成矿作用、表生成矿作用5个方面概括总结了各矿种的成矿地质特征；以成矿系列理论为指导进行了全市区域成矿规律研究，将天津全域划分为“Ⅲ-57华北陆块北缘东段Fe-CuMo-Pb-Zn-Au-Ag-Mn-U-磷-煤-膨润土成矿带”和“Ⅲ-62华北盆地（断坳）油气成矿区”两个三级成矿带，在三级成矿带的基础上划分了6个四级成矿亚带、4个五级矿集区，从空间和时间两个角度分析总结了全市矿产资源演化规律。该项成果是天津市矿产地质领域里程碑式的研究成果，深化和提升了成矿规律研究水平，对今后的找矿勘查部署具有重要的指导意义。 |
| 英文摘要: |
| The geological conditions for mineralization in Tianjin are complex, which have given rise to abundant mineral resources. 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 Volume, systematically summarizes the achievements of over a century of mineral resource exploration in Tianjin City and outlines 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 aspects: 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 division 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. |
