摘要
产于塔里木地台铁克力克隆起内的钾镁煌斑岩岩石化学成分与亚洲钾镁煌斑岩的平均岩石化学成分接近，与澳大利亚西金伯利地区钾镁煌斑岩一致。稀土元素、微量元素组成与世界已知钾镁煌斑岩具有相同特征。铁克力克隆起南缘柯岗一塔伦深断裂南北具串珠状分布的超镁铁岩体，与钾镁煌斑岩具有相同地质背景。该深断裂与西昆仑北缘深断裂交汇处是寻找含矿钾镁煌斑岩的有利部位。
The petrochemical composition of lamproites produced in Tekelike uplift of Tarim platform are very close to the average comoposition of Asia lamproites and coincide with those of the west Kimberley lam- proites of Australia. Their REE and microelement’s composition exist the common characteristics with the world known lamproites. There are many ultramafic rock bodies.Which moniliformiy distributed in the north and south side of Kegang-Talun deep-seated fault in south margin of Tekelike uplift,and has common geo- 1ogical setting with lamproites. The intersection area of that deep-seated fault with deep-seated fault of north margin of West Kunlun is the forecasting area of lamproites diamondferous.
