目前,国内已经积累了200多个与夕卡岩铁矿有关的同位素年龄数据,并发表了许多有关成岩成矿时代划分的文献,为解决若干地质问题提供了依据.但对该类铁矿的成岩成矿时代划分,目前还没有统一的认识.本文根据收集到的236个U-Th-Pb法、Rb-Sr法、K-Ar体积法和K-Ar稀释法同位素年龄数据(其中黑云母、角闪石单矿物数据114个,全岩数据116个,锆石单矿物数据5个,磁铁矿、正长石等单矿物数据28个),对一些与夕卡岩铁矿关系密切岩体的数据进行了数学处理,以277个数据为基础,获得 At present, more than 200 isotope age data have been accumulated in China and a lot of literatures about the division of diagenetic metallogenic age have been accumulated in our country, which provide a basis for solving some geological problems. However, According to the collected data of 236 U-Th-Pb methods, Rb-Sr method, K-Ar volume method and K-Ar dilution method, in which the biotite , Single amphibole mineral data 114, total rock data 116, zircon single mineral data 5, magnetite, orthoclase and other single mineral data 28), and some closely linked with the skarn iron ore Body data were mathematically processed, based on 277 data obtained
