新疆东昆仑迪木那里克铁矿床地质特征及找矿方向
Geological characteristics and prospecting direction of Dimunalike iron deposit in East Kunlun, Xinjiang
摘要
Abstract
Based on geological background and geological features, this paper deals with the genesis of the Dimunalike iron deposit and the ore-prospecting criteria in search for ore deposits of the same type, with emphasis placed on such aspects as the deposit size, attitude of ore body, ore-bearing horizon, surrounding rocks and ore characteristics. The Dimunalike iron deposit is located in the western part of East Kunlun in Xinjiang. Its tectonic position is the Qimantag Paleozoic complex trench-arc belt in Altun continental margin block. The deposit mainly occurs in metamorphosed clastic rocks - pyroclastic rocks of the Middle-Upper Ordovician Qimantag Group. Most ore bodies are nearly stratiform or banded, some have undergone strong plastic deformation, and ores mainly show obvious stratabound nature. The ores are mainly banded quartz-magnetite and bulk magnetite, with a relatively low grade (TFe = 20% ~40%), and wall rocks have obviously experienced alteration. The iron ore is of the sedimentary-metamorphic type, and hence the stratigraphy, tectonics, rock alteration and aeromagnetic anomaly can be used together for ore prospecting.关键词
