The Inner Mongolia Niuer River Survey Area Geophysical Composite Anomalies Inference And Interpretation Of Research

In order to increase the strategic reserves of resources, Hulunbeier Chihong Mining Co. Ltd.Entrust our school to carry out IP intermediate gradient,IP sounding and EH4 work in niuer river Inner Mongolia.To find Cu, Mo, Pb, Zn, Ag insidious Minerals etc.Niuer river survey area is located Derbugan faults, Belongs to Pb, Zn, Ag, Au, Cu, Mo, U metallogenic belt of Derbugan Yanshanian, the next forest-Xi Jinuo Pb-Zn-Ag-Au-Cu mineralization sub-zone. NorthEast of the Wu Nuge, Ba Bayi and Ba Daguan Copper-molybdenum Deposit, derbur Pb, Zn, Ag deposit, north of the Wu Nuer Copper-molybdenum Deposit,SouthWest of the Xia Jinuo lead-zinc mine, East of the black hills-room Wei Au metallogenic belt. Soil measurements showed that survey area has good Cu, Mo, W, Bi, Pb, Zn, Ag and Au anomalies, abnormal strength. Thus, the measured area has the potential to looking for lead zinc silver gold copper molybdenum tungsten mineral.In this paper completed a total of 7.6Km point measurement,7.2Km IP intermediate gradient measurement,10 points IP sounding and 268 points EH4 sounding measurement.Survey area Circled a total of 5 IP intermediate gradient apparent chargeability anomaly, the trend of Anomaly about 160°, Qualitative study of the abnormal, There are 3 abnormal caused by Mineralized bodies,1 caused by faults and Mineralized bodies,1 caused by diorite; Semi-quantitative interpretation IPM4 abnormal with flume experiment of textbook, Hypothesized that the polarization body as plate shape body, tend to west; Using the experience of tangent method to study the top buried depth of the abnormal body about 70 meters.Survey area Circled a total of 3 abnormal, Combining the textbook flume experiments to study the nature, tendency and morphology of IP Sounding anomaly body,1 abnormal caused by disseminated mineralization body,2 caused by vein and net vein; Semi-quantitative analysis the abnormal body's top buried depth in 70～120 meters using the take-off point method, inflection point method and saturation point method. Survey area Circled a total of 3 EH4 Abnormality of low resistivity zone, anomalous zone to about 160°,2 anomalous zone caused by Mineralized bodies,1 caused by the faults and Mineralized bodies, Abnormal EH4 and IP intermediate gradient anomaly anastomosis; The morphology of Polarization body which Cause the IPM4 abnormality is same as EH4 low resistance body. Meanwhile, this paper also studied the Effects of errors in MN error in length and deviation in direction on Apparent resistivity in EH4, summed up the effects of the level of magnetic declination and inclination in EH4.Survey area Circled A total of 3 integrated geophysical anomaly zone, Inferenced the north abnormal body top depth is large than the south in band and West belt, the shallow anomaly of North in West anomaly belt caused by disseminated mineralization body, deep anomalies caused by vein and stockwork sulphide; middle anomalies belt caused by vein and stockwork sulphide and fault; East with abnormal caused by vein and stockwork sulphide.Comprehensive study measuring geological, geophysical and geochemical data, combined with the adjacent deposit characteristics, to establishment the model of geological, geophysical anomaly prospecting of measuring.
