Anomalies Delineation And Genesis Of Geochemical Prospecting In Thirty Kilometres Of The Aershan City Area

The east region of Arxan City locates in the Cenozoic NNE on the western Pacific tectonic metallogenic domain and Paleozoic EW Asian tectonic metallogenic domain binding site.Daxinganling region is superior in the mineralization of times,large mineralization intensity,deposit types,mineralization geological conditions.Workspace located in 200,000 scale geochemical of Wuchagou web north-central east-west length of 57 km,north-south width of 18.5km,sweep across 200,000 scale geochemical surface anomaly delineated integrated element 7.The study area has not yet been undertook 1: 50,000 or larger scale work,lower degree of research,this study of 300,000 km Haosengou outside the station(Wudaogou),within three toad ditch Woodland map sheet carried 1: 50,000 based on the amount of the probe,test and analysis of gold,silver,copper,lead,zinc,molybdenum,delineated anomalies associated elements and ore elements exception;utilized geological,geophysical and geochemical methods and surface engineering and other means of 1:50 000 Geochemical related verification,and the exploration prospect of the abnormal area and make the appropriate evaluation,delineation of prospecting targets for further work.The study area generally identified stratigraphic,tectonic,magmatic activity and other characteristics,with circled the north east and north west two metallogenic prospect(area).Integrated element anomalies in the spatial distribution of both along the north east or north east was broadband-like distribution.Pb,Zn,Ag polymetallic anomalies located west of the study area,and construction(Gas)related hydrothermal and carbonate formations.Mo polymetallic anomalies in the eastern part of the study area,Jurassic granite and granite porphyry with large distribution area,and magmatic hydrothermal alteration(partial)enrichment-related.The integrated elements of regional anomalies prospecting make a preliminary evaluation,delineation of the three prospecting targets were on the 4th groove(AP4),the 1st groove(AP11),three tributary(AP8),are now It has been found lead-zinc silver()bodies,on the 4th groove(AP4)were discussed in detail analysis.While the latter two anomalies brief analysis,three tributary(AP8)exception based on regional geological mineralization and alteration characteristic analysis,it concluded that the exception may be caused by abnormal mine.
