| 摘 要： | 辽宁省瓦房店地区是中国著名的金刚石矿产地之一,矿床类型属于金伯利岩型金刚石矿床。通过研究区域构造背景,结合最新项目研究成果,将辽南瓦房店金伯利岩矿区构造演化过程划分为7个构造旋回,讨论辽宁省瓦房店地区不同构造旋回的特征及对金伯利岩的影响,得出加里东期近东西向构造控制着辽南金伯利岩的产生及成矿作用。燕山期断裂构造对金伯利岩的展布起控制作用,认为本区金伯利岩的成矿阶段可由古生代延至中生代。

| Abstract: | Wafangdian area in Liaoning Province is famous for rich diamond resources, and the diamond deposit belongs to kimberlite type. Based on the study of the regional tectonic setting and the latest project research results, the authors divided the tectonic evolution process of kimberlite orefield in Wafangdian area into seven tectonic cycles. By discussing the characteristics of different tectonic cycles in Wafangdian area of Liaoning Province and analyzing their influence on the kimberlite, the authors have reached the conclusion that the nearly EW-trending structure controlled the formation and mineralization of the kimberlite in the south of Liaoning Province during Caledonian. Yanshanian tectonic activity altered the distribution of the kimberlite. It is considered that the mineralization stage of the kimberlite rock in this area can be extended from Paleozoic to Mesozoic. |
