摘要
约马克其地区位于阿尔金南缘断裂带中段,处在复杂的大地构造环境中。化探扫面发现区内水系沉积物异常多呈带状沿断裂带分布,基性—超基性杂岩体是引起大而强异常的主要原因。通过对岩体的岩石化学特征、微量元素地球化学特征、稀土元素地球化学特征的剖析,发现是同一岩浆结晶分异的产物,在大陆构造环境形成。本区主要矿产为铜,辉长辉绿岩是主要的含矿层位,最终提交铜资源量15万吨。。
Yemakeqi area is located at the central part of the southern edge of Altun region in Xinjiang. Watedaid sediment with zonal distribution occurred along the faulted zone. Basic and ultrabasic complexes are major factors responsible for the formation of large and strong anomalies. Based on an analysis of geochemical characteristics of rocks and trace elements as well as rare earth elements, the result shows that they are products of crystallization differentiation of the same magma and formed in continental structure environment. Copper is the major ore in the area. The main orebearing layer is composed of gabbrodiabase. It is estimated there is copper resource of 150 000 t in the area.
