Gold Metallogenic Potential Analysis Of Kanas Area In Western Altay Mountain, Xinjiang

The Northern Xinjiang Altay rare(RM)-Pb-Zn-Au-Muscovite-Gem metallogenic belt in NW-SE direction,west extension to Russia and Kazakhstan,east extension for Mongolian Altai,is a unique and important giant metallogenic belt. Kanas Cu-Au ore belt is located in the extreme north of this belt,south in EW to the Yilaike fault as the boundary,the length of about 120 km,the width is about 90 km,the large distribution area of early Paleozoic metamorphic flysch(Kanas group), and is the late Ordovician,late Silurian- early Devonian intrusive acidic intrusive rocks,regional hydrothermal metamorphism obvious,partial formation of various types of gneiss,schist construction. Altay metallogenic belt is one of the important belt which have been discovered in southern Ashele copper deposit,Duolanasayi gold deposit etc.,it showed good mineralization potential,but the north due to the limited degree of geological work,has not been found molded gold,copper and other mineral deposits.With the development of geological exploration in recent years,many showed good gold mineralization clues, such as Jaysan areas.Therefore in urgent need of the modern metallogenic potential evaluation method, systematically to the north of altay, especially gold metallogenic potential evaluation of kanas ore belt,in order to lay a foundation for mineral exploration deployment.Taking Kanas-Hemu as the study area,based on the 1:50000 regional geological and mineral survey project,Duolanasayi gold deposit as an typical deposit,start from the geological background and 4 known alteration rock gold deposit(point) of study area,fully excavate the mineralization clues,and compared with the typical deposits(Duolanasayi gold deposit)in the area,combined with field verification and system analysis,this paper established the metallogenic model and the favorable extraction model,based on ArcGIS platform,the establishment of the multivariate geological spatial database of research area.Due to the limited research on known gold deposits and metallogenic regularities,do not have completely data-driven model applicationconditions,and to the regional metallogenic models are integrated into the prediction model,but because of the development of better 1:200000,1:50000 geochemical anomalies, and has a good ore-forming potential, using ArcGIS spatial analysis platform of single factor analysis and two factor combined analysis method, as predicted by the model are advantageous to the mineralization information were fast,accurate extraction and processing.Finally regional geochemical data are utilized to validate these prospecting areas,and gold two target areas are forecasted.Combined with the main mineral occurrences, the metallogenic geological conditions of the target area are discussed,and the prospecting potential of this region is analyzed.In order to provide theoretical basis, technical support and data support for further gold exploration in the study area,to serve for the exploration and deployment of gold deposits in the study area.
