1017high silver lead and zinc gold polymetallic deposit is located in the Inner Mongoliaautonomous region east WuZhu MuQinQi, mine tectonic position in Siberia plate in the southeastedge of chagan aobao-he’s-especially in not stare blankly early palaeozoic tectonic-the magmatitebelts (Inner Mongolia geological chi). Silver polymetallic ore body mainly occurs in the mud basinsystem ingres sound uralian group of sandstone and variscan medium-term monzonitic granite, oretype is mainly quartz vein type ore and alteration monzonitic granite type ore. This research, in theroute of the1:50000geological survey, based on the comprehensive analysis of geology, geophysicalsurvey1017high area, geochemical exploration, and remote sensing information features,understanding metallogenic background and ore-controlling factors, summarizes mineral distributionrule and deposit origin to explore.The work of ringed mountains belongs to xinjiang uygur autonomous region, tianshan mountain,utilize modern formation-utilize modern stratigraphic area, east black flag-huma stratigraphicdivision, exposed have ordovician, late devonian, the late carboniferous-early Permian and Jurassic,cretaceous and the fourth system holocene deposit. For the late yanshanian acid intrusive rock, fromlithofacies change look, in the coarse grained biotite adamellite and fine grained biotite monzoniticgranite. The research fault main tectonic line direction for north east to, and the other two groups faultdirection as north west and nearly east-west, north and east to the most development. The study area islocated in the east in erlian-black flag anticlinorium north wing, second level structure unit aremainly AQin ChuLu compound anticline and frontal kernel high burt compound synclinal. Researcharea ductile shear zone only in ha DingTao le cover-ChaGanChu lu area development.By factor analysis, and the commonly used multivariate statistical methods to reveal betweenelement and element and geologic function relationship between, to understand which contain richmetallogenic information for the research of the area of metallogenic regularities and ore depositorigin provide basis.1017high field drilling sample trace elements R type factor analysis results showthat magma activity mineralized material activation, magmatic hydrothermal late evolution, due to theactivity and temperature is reduced, gradually evolved into metallogenic hydrothermal, in the rock mass near the contact zone in the fissure structure position is rich in Pb, Zn, Ag metallogenichydrothermal enrichment precipitation. Through analysis it is believed in the mine ore bodydenudation is shallow and deep have good prospecting potential.In the field work, choose the advanced controlled source audio-frequency magnetotelluricinstrument, strictly in accordance with the standard setpoint cloth station, point by point long timeobservation records, made a lot of original field data. In the interior, how to data processing andinversion will directly relates to whether get reliable interpretation results. Modern controlled sourceaudio-frequency magnetotelluric method development, has formed some advanced processingmethods and techniques. In the controlled source audio-frequency magnetotelluric data processing,adopted the advanced research results in the method to obtain the reliable geoelectric model toprovide the safeguard. In the Inner Mongolia autonomous region east WuZhu MuQinQi1017highland mine completed the controlled source audio-frequency magnetotelluric sounding sectionnine to nine section of controlled source audio-frequency magnetotelluric sounding data materialpretreatment,2d inversion, won nine section of resistivity model. To the resistivity model inferenceand interpretation. Will the third electrical layer of16large low resistance electrical body inferencefor ore (mineralized) bodies distribution relatively advantageous position.Use of armed police gold research institute and the cooperative research, carries on themetallogenic regularity and metallogenic mechanism to explore. To mine ore deposit origin haveobtained the very good explanation, thus attaining the objective and the expected effect.The results of this work reflects the comprehensive information and the application of theproposed method, this paper discusses the deposit genesis and metallogenic regularities in the1017highland my mining area has feasibility and validity, clear the prospecting direction, further guidesubsequent ore-prospecting work.
