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 from the Cretaceous uplift in the Tarim Basin is similar to the average petrochemical composition of the Asia-Asia lamproite and is consistent with the lamproite from western Kimberley, Australia. The REE and trace element compositions have the same characteristics as those of the world known calcite lamprophytes. The ultramafic intrusions with bead-shaped distribution in south and north of Kegang-Tailun deep fault on the southern margin of Tieke Kelixu have the same geological background as that of lamprophorite. The deep fault and the deep fault intersection at the northern margin of Western Kunlun are favorable sites for searching for ore-bearing lamproite.
