江西景德镇地区中生代推覆构造变形特征与年代学约束
DEFORMATION CHARACTERISTICS AND GEOCHRONOLOGICAL CONSTRAINTS OF MESOZOIC NAPPE STRUCTURE IN JINGDEZHEN AREA, NORTHEASTERN JIANGXI
摘要
Abstract
Jingdezhen area is located in the northeastern Jiangxi province,which belongs to the Yangzi plate,and has undergone long-term tectonic activities.According to the study of regional tectonic section,the Mesozoic thrust-nappe structure direction of the study area is from NW to SE,the upper Shuangqiaoshan group has been pushed to the top of Carboniferous-Triassic strata,and the structural styles of the thrust belt are characterized by imbricate fans and duplexes and the maximum principal compressive stress is SE-NW trend.The study of undeformed granite zircon U-Pb isotope dating shows that the U-Pb isotope age is 157 ~ 172 Ma,and the time of tectonic movement is during early Yanshanian period.The Mesozoic thrust-nappe structure produced the magmatic mineralization process in the Jingdezhen area,and the granites of Jingdezhen area may have invaded from intracontinental subductionrelated transformation tectonic setting during the early Yanshanian.The nappe structure constrains the magmatic evolution and in space associated with mineralization.Then it controls the mineralization process of the deposit.关键词
