The Study Of Geological Feature Genesis Of Songhu Iron Ore In Nilka County, Xinjiang

Recent years, with the flourished of Western Tianshan geological survey project,there have been discovered a number of medium-large-scale iron-copper in Awulaleiron and copper metallogenic belt. Researching the geological features and causes ofsonghu iron ore that located on the Awulale iron and copper metallogenic beltprovides some guidance of the general survy songhu iron ore’s deep and peripheral,at the same time it has a certain refrence vlue for recerching of this iron ore belt’ssame tipe of deposit.I make a fild surveys on the Nilka County Songhu iron ore mining district andoutlying areas, and by chemical analysis test sample of major elements, trace elementsand REE elements(using X-ray fluorescence and ICP-MS) kinds of comparativeanalysis we can get following understanding:1.Route through the wild Geological Survey measured the system profile, chemicalanalysis and testing work, I think that the the Pine Lake iron ore mine outcrops mainformation for the next the Carboniferous Awulale group. The petrochemistry type is aland of tholeiitic series and calc-alkaline series, and closely related to mineralization.The main rock tipe is meddile–fine andesitic tuff, tuff breccia, part of crystalfragment glassy tuff.2.Songhu Mine is located in the north wing of the Awulale anticlinorium, fold andfault structures are well developed, different phases of varying intensity magmaticactivity along the tectonic development, the fault structure into minerals providesufficient material sources.3.The main ore of the study area has a dense disseminated-massive structure, IronOre minerals are mainly magnetite, metal sulfides by pyrite, chalcopyrite mostly.Gangue minerals tremolite, actinolite of stone, epidote, chlorite, garnet, quartz, calcite.4.Mine mineralization: magnetite, maghemite and hematite, pyrite, and limonite, chalcopyrite mineralization, peacock, petrochemical, specular hematite, andsilicification, carbonate, chlorite. Alteration types carbonation, chlorite mainly bylimonite, silicification. The late alteration, mineralization strength of compressionfracture inverse (red) and associated hydrothermal activity control.5.Pine Lake iron ore geochemical characteristics analysis shows LREE enrichment,HREE, light and heavy rare earth differentiation obvious. The rare earth elementstogether with their regional volcanic rocks with similar characteristics. Would bejudged as minerals derived from volcanic action.6.West Awulale, copper and iron polymetallic metallogenic belt contains abundantmineral resources. The band in addition to the Pine Lake Iron preparing for iron ore,iron ore Tomohiro Chagang Noel iron ore, type bar iron ore constitute the depositseries related rift zone, that A Chawola Le Rift Valley also has the potential to findiron ore can be used as a new iron ore prospecting areas.The study causes of Pine Lake Iron Pine Lake Iron the marine volcanic hydrothermaldeposits, mineralization mainly volcanis.
