摘要
阿日特克山钼矿床是近年柴北缘成矿带东段新发现的一处斑岩型钼矿床。本文通过分析研究其成矿地质背景、矿床地质特征,通过锆石U-Pb同位素定年着重研究了成矿岩体特征及形成时代,确定其成岩地质年代为早三叠世晚期至中三叠世早期,侵入时代属印支期,成矿岩体成岩年龄与钼矿成矿年龄基本一致。并总结分析了矿床形成过程和矿床成因,明确了构造作用对成矿的影响,为该区今后的地质找矿和理论研究提供了基础。
Aretekeshan molybdenum deposit is a porphyry molybdenum deposit newly discovered in the east of the northern Qaidam metallogenic belt in recent years.In this paper,through analysis and study on its metallogenic geological background,ore body and ore characteristics,the U-Pb isotope dating of zircon,the characteristics and formation age of ore-forming body are emphatically studied.It is determined that geological age is late Early Triassic to the early Middle Triassic.The intrusive age is Indosinian,and the ore-forming age of ore-forming body is basically the same as that of molybdenite.The origin of the formation process of the deposit have been summarized and analyzed,the influence of tectonism on the mineralization has been clarified.It will provide the basis for geological prospecting and theoretical research in this area in the future.
