Alteration of Wall rock of ore body Fe I in Chagannur Iron Deposit, Hejing County, Xinjiang
摘要
Abstract
The Chagannur ore deposit lies in the northern part of the Ili block, just in Bonohonu island arcbelt and belongs to the east of Awulale metallogenic belt.There are lots of deposits in Awulale metallogenic belt, such as gold mineralization, copper mineralization, lead mineralization, zinc metallogenic and iron metallogenic.Dahalajunshan formation and Yishijilike fornmation is mainly volcanic rocks in mine area, with fault contact relationship between them.Alteration of wall rock is widely distributed in mine area.There are lots of alteration zones along the fracture because of multi-activity of ore magma.The study results show that from east to west, there are garnet belt, epidote-actinolite belt,actinolite-magnetite belt, alternating griotte belt and actinolite rock.And three period of alteration caused these belts.Symbiotic combinations of the various stages of minerals are: magnetite + diopside + garnet ;magnetite + actinolite + epidote; magnetite-garnet-actinolite-epidote-quartz-carbonate salt.The mining alteration is formed by high, middle temperature volcanic hydrothermal liquid and acidic volcanic rocks.关键词
