摘　　要：本文研究了粤东梅州市丰顺县茶背岩体的年代学和地球化学特征,研究发现岩体形成时代为早侏罗世,为高钾钙碱性花岗岩。早侏罗世花岗岩在粤东地区零星出露,目前并未发现相关矿床,而在赣南-粤北地区存在与之相关的矿床。因此在粤东地区有早侏罗世成矿潜力,这为找矿工作提供了新的思路。This paper studies the chronology and geochemical characteristics of chabei granites in Fengshun county,Meizhou city,eastern Guangdong province,and finds that the formation age of chabei granites is early Jurassic,high k calc-alkaline granite.Early Jurassic granites are sporadically exposed in eastern Guangdong and no related deposits have been found at present.However,there are related deposits in southern Gannan and northern Guangdong,so there is early Jurassic metallogenic potential in eastern Guangdong,which provides a new idea for further prospecting.
