宁夏卫宁北山地区矿床类型及成矿时代
Metallogenic epoch and ore-forming types of ore depesits in Weiningbeishan area, Ningxia
摘要
Abstract
Considering the favorable prospects for forming large complex deposits in the Weiningbeishan area of Ningxia because of its unique tectonic structure circumstances and regional mineralization background, the authors' researches focused on this promising area. A study of the typical Huangshipo ore block reveals that the quartz diorite porphyrite veins widely exposed here are closely related to mineralization. In order to further confirm the metallogenic epoch, the authors used for the first time zircon microdomain dating technology in the study area. In Errenshan and Jinchangzi areas, sampling of zircons was conducted in quartz diorite porphyrite veins existent in the typical ore block. Zircon dating has confirmed that there are two-period magmatic intrusions in the area, they all related to mineralization. The authors also systematically investigated the deposit type for the first time, and found that it is of the structure-magmatic hydrothermal ore-forming system. The ore deposit should be of the low-to-moderate temperature hydrothermal type, and the industrial type should be tectonic alteration type.关键词
