摘　　要：针对塔里木南缘铁克里克地块赫罗斯坦片麻杂岩中TTG深成片麻岩、基性片麻岩、富钾质深成片麻岩及阿喀孜深熔片麻岩和辉绿岩脉,通过岩石学、岩石地球化学、同位素地球化学研究,初步查明铁克里克地区早前寒武纪岩石组合特征,为该地区建立构造-岩浆热事件序列提供科学依据。Based on the study of TTG plutonic gneiss,basic gneiss,potassium rich plutonic gneiss,Akazi deep melt gneiss,and diabase veins in the Helostan gneiss complex of the Tiekrik block on the southern edge of the Tarim Basin,through petrology,rock geochemistry,and isotope geochemistry,the early Cambrian rock assemblages in the Tiekrik area were preliminarily identified,providing a scientific basis for establishing a sequence of tectonic magmatic thermal events in the region.
