Abstract
This paper systematically summarizes the spatial distribution patterns and formation settings of pyrophyllite deposits in China.Integrating the key periods of tectonic evolution,it analyzes the controlling effects of different tectonic cycles on pyrophyllite mineralization and clarifies the correspondence between deposit genetic types and tectonic environments.The study indicates that the formation of pyrophyllite deposits in China is closely linked to volcanic activities and plate movements.These deposits are mainly concentrated in three major tectonic evolutionary stages:the Mesoproterozoic-Early Neoproterozoic,the Late Neoproterozoic-Late Paleozoic,and the Mesozoic-Cenozoic,corresponding to four tectonic cycles(Jinning,Caledonian,Variscan-Indosinian,and Yanshanian).Significant differences exist in mineralization characteristics and genetic types among different stages.Among them,hydrothermal deposits account for 90%and constitute the primary targets for industrial exploitation,while metamorphic deposits hold important geological indicative significance.The research findings provide a theoretical basis for the exploration and study of pyrophyllite deposits.关键词
