Research For Halos And Mineralization Of The Basic-ultrabasic Rocks In Huangshan,Xinjiang

Huangshan area is one of the main Chinese basic-ultrabasic temperature magmatic Cu-NiSulfide Deposit of the main mining area, is our country‘s the important origin of Ni, PGE, Co,Cu mineral resources. This article selects the xinjiang region of Huangshandong,Huangshannan,Jingerquan，Tulargen as figure, with deposit as the basic-ultrabasic rock oreinto a faint object of study. Mainly on the Huangshandong, Huangshannan,Jingerquan，Tulargenfigure, with the geological characteristics of rock mass, rock mineralogical characteristics, oredeposit, the basic characteristics of the research focuses on Huangshandong orebody no.2rockgeochemical characteristics and ore body prospecting line primary halo feature research.Through the field work and indoor work mainly known is as follows:(1) The mineral is mainly related to volcanic formation, as orogenic belt type small rockbody of mixed rock deposits. Rock combination generally have lherzolite-olive two pyroxenite-two metamorphic facies; Mafic rocks combination generally have bright green gabbro, gabbro,norite-gabbro diorite. Ultrabasic rock consists of peridotite, oblique Fang Hui throws rocks, faiShi Jiaoshan peridotite, lherzolite, throws pyroxenite flash peridotite, pyroxenite, long obliqueAngle; Rock by olive norite, gabbronorite (40%), gabbro (75%), gabbro, diorite and diorite(60%), quartz diorite.(2) The Huangshandong orebody No.2prospecting line rock geochemical analysis resultsfor: A, abnormal analysis, trend analysis, we can see the main ore-forming elements copper,nickel element and nearly mineral element anomaly distribution range is wide, high industrialvalue. B, the relationship between the phase analysis, cluster analysis, factor analysis, we cansee the copper and nickel ore deposit main indicator elements are Co Ni Mn Cr Cu Zn,secondary indicator elements are: Au Bi Pb As Ag..(3) The Huanshandong chemical halo analysis results as follows: through intuitivecomparison primary halos horizontal zoning sequence is: V-Sb-Cr-Zn-Mn-Co-Ni-Cu-As-Pb-Au-Bi-Ag. The head hole: V-Sb-Cr-Zn; near-ore hole: Mn-Co-Ni-Cu; tailhalo As-Pb-Au-Bi-Ag. Through the abnormal concentration method the primary haloshorizontal zoning sequence is: Zn-Sb-Cu-Mn-Ni-Cr-Au-V-Pb-Co-As-Bi-Ag.Through income R factor analysis and R factor analysis three main factors represented by the elements of the same combination, F1, F2and F3, respectively, represents the main ore-formingelements, dizzy and dizzy. By superposition of ideal model can see that the ore body as a wholeis a downward inclined orebody in turn from the south to the north, the main mineral elements,as well as nearly all mineral element anomaly degree is higher, the head dizzy anomaly of F3element combination, can form more visible in the orebody of deep rich mineral deposits. Butthe formation of the ore body is related to magmatic explain its primary halo formation and theore body at the beginning of the formation of rocks and minerals has a lot to do.
