苏皖沿江铀成矿地质特征及找矿方向探讨

本文试图在多年工作的基础上,以8411矿床和501矿床为例,对苏皖沿江一带具有代表性的两种类型铀矿床的地质构造背景、成矿特点、控矿因素、矿床产出特征、矿床物质组成、溶液成分、围岩蚀变与成因机制等问题进行论述,并以此总结其区域成矿规律,深入探讨找矿方向。

AN APPROACH TO GEOLOGICAL CHARACTERISTICS OF URANIUM METALLOGENESIS AND PROSPECTING TARGET ALONG THE YANGTZE RIVER IN JIANGSU AND ANHUI PROVINCES

Based on personal geologic prospecting practice in Jiangsu and Anhni provinces for many years, and taking ore deposit No. 8411 and No.501 as examples, the author attempts to deal with geologic-structural setting, metallogenetic features,ore-control factor, attitude of ore deposit, material composition of the deposit ,components of ore-forming fluid, wall rock alteration and mechanism of ore genesis in two types of uranium deposits representative of the zone along the Yangtze River. In terms of this their regional metallogenetic regularity is summed up and prospecting target is deeply inquired into.
