Discussion on the Regional Mineralization Law of Iron Ore in the North Mountain of Weining Area,Ningxia
摘要
Abstract
Weining North Mountain area lies in the east of Hexi Corridor Fe-Mo-Fluorite-Salt- Attapulgitepetroleum metallogenic belt, where is one of the most important perspective regions of the mineralization of metallic minerals in Ningxia, having many significant metallic minerals such as gold, sliver, and copper.For a long time, the understanding about iron ore mineralization in the area are much different.We discuss the regional mineralization law of iron ore in the area from the way of typical deposit and the regional deposit, obtaining a primary conclusion about the regional mineralizing law of iron ore including genetic type.We also believe that the iron ore mineralization of Weining north mountain area mainly occurred in Carboniferous-Permian, which is characterized by the sedimentary mineralization in the early stage and by the tectonic-hydrothermal activities in the late; the stratum and lithofacies and lithology are the main control factors of iron ore mineralization and the geologic structure's function is minor because major mineralization is deposition, though it plays a certain positive role in mineralization; the exploration direction of iron deposits in the area should focus on the deposition's siderite first, and then hematitelimonite which is formed by superimposition transformation of deposition siderite seam and tectonic (faults).关键词
