摘要
从岩石地层学的角度探讨海南省抱板地区赋金地层的时代问题,记述了抱板群的岩性、接触关系、锆石的同位素年龄及岩石化学和微量元素组合的特征,并以此来划分地层及讨论含金地层的时代归属,认为抱板群的地层时代应划为中上元古界。
The age of the gold-bearing stratum in Baoban region of Hainan from the point of lithostratigraphy has been dealt.The lithological charaters of Baoban Graup,contact relationship,U-Pb isotopic ages of zircons and trace elements con-tents of the stratigraphic rocks have been described,based on which the stratigra phic age has been discussed.It is thought that the stratigraphic age of Baobon Graup may be middle-upper Proterozoic era.
