摘要
通过总结玉希喀拉综合异常区特征、分析异常地质背景，探讨了异常区找锡的前景，指出玉希喀拉花岗岩为非含锡矿花岗岩，锡成矿可能性小。认为该异常是由于岩体多次侵入引起Ａｎ、Ｃｕ、Ｓｎ等元素三次活化、迁移、聚集的结果。
This paper expounds the characteristics of geochemistry abnormalily for the tin,gold,copper elements in Yuxikala area,nd analyses abnormal geological settings.According to petrology,petrochemistry,eochemistry and rare earth elements characteristics of granitoids,point out this granite is barren tin granite which is not possible ore-forming tin deposits,and consider that synthetic abnormalily was due to ore-forming elements activate.migrate and enrichement by multiplty magmatism.
