摘　　要：新疆博乐市乌兰达湾地区位于新疆西天山北西部,东邻准噶尔盆地西南缘,属赛里木地块古生代复合岛弧带、古亚洲铀成矿域-天山铀成矿省-北天山铀成矿远景带。运用火山岩型铀矿床理论,通过地质、物化探综合找矿方法,开展找矿标志研究工作,确定研究区“四位一体”找矿方向,达到找矿目的。研究区铀成矿与火山岩岩性、岩相条件、构造条件、蚀变条件、基性岩浆活动条件密切相关,且4个条件并不孤立,叠加耦合地段为铀矿化发育有利部位。该区找矿方向主要有:红化(赤铁矿化、褐铁矿化)蚀变带-次级断裂构造控制部位;NE向构造夹持的NW向构造破碎蚀变带或密集裂隙带;侵入次级NW向、近NS向断裂中的辉绿岩脉,热液上升为铀元素富集提供通道,附近可见铀矿化。The Wulandawan area of Bole City,Xinjiang is located in the northwestern part of the western Tianshan Mountains,and adjacent to the southwestern margin of the zhungeer Basin in the east.It belongs to the Paleozoic composite island arc zone of the Sailim block and belongs to the ancient Asian uranium metallogenic domain-Tianshan Uranium Metallogenic Province-North Tianshan uranium metallogenic prospect zone.This paper uses the theory of volcanic rock type uranium deposits,through the comprehensive prospecting methods of geological and geophysical prospecting,carried out the research work of identifying the prospecting signs,and determined the prospecting direction of the“four in one”in the research area,and achieved the purpose of prospecting.It is believed that the uranium mineralization in the study area is closely related to volcanic lithologic lithofacies,tectonic conditions,alteration conditions,and basic magmatic activity conditions,and the four conditions are not isolated.The superimposed coupling section is a favorable location for the development of uranium mineralization.The main prospecting directions in this area are as follows:Reddish(hematite,limonite)alteration zone-the control location of the secondary fault structure;NW trending structural fracture alteration zone or dense fracture zone was sandwiched between NE trending structure;intrusion of diabase veins along secondary NW-trending and near-north-south faults.The rise of hydrothermal fluid provides a channel for uranium enrichment,and uranium mineralization can be seen in the vicinity.
