Element Geochemical Characteristics And Geochemical Prospecting Effect Of Hongtugou-hongshishan Area In Golmud,qinhai Province

Kun Lun east area is one of the important metallogenic belt in the Qinling-Qilian-Kunlun metallogenic belt. In recent years,through comprehensive exploration,a number of important metallic ores have been found in Clay Ditch-Red Rock Hill of Golmud City. On the basis of collection,analysis summary of previous geological,useful mineral,geophysical and geochemical exploration,scientific research achievements,through the 1:50000 stream sediment survey and high-precision ground magnetic survey,geochemical rock profile survey and test trench engineering verification,Preliminary view element geochemistry characteristics of Proterozoic Wanbaogou Gr,Late Paleozoic Devonian,Caledonian,late Variscan Indo magmatic cycle for metallogenic element concentration rate is high,large-scale change;Volcano and magma carrying more ore-forming materials is the key area of mineralization;Mineralization accompany with the intrusion and eruption of volcanic magmatism,magmatic ore forming process and telescoping are main mineralizations.Ore-forming element composite anomaly,that is mainly controlled by nearly EW and NW faults,Cenozoic no fault of multi-element anomalies showed that only Hg and Sb,As and other strips,beaded abnormal distribution.Statistics and unusual elements background check showed that the area belonged to important research into mining(strip),can be divided into grade mineralization with a large resource potential,is looking for gold,copper,lead,zinc,cobalt,antimony and other deposits in the important zone.According to the geological unit mine evaluation containing and ore-forming elements abnormal distribution of,integrated geological Mineralization Law identified five prospecting targets, abnormal verification work confirmed that the red clay ditch, the big Grenoble ditch and a number of gold and copper abnormal do exist and good prospecting.According to regional distribution of multi-element background and combinations of features was tectonic and geochemical zoning, anomalies reflect the main faults of Mid Kunlun and south Kunlun with high background of Fe,Cu,Co,Ni etc. elements group and anomalous distribution of that reflect the region mafic volcanic rocks characterized.Stream sediment distribution element show the elements of levels and regional distribution in the district objectively. Integrated anomaly delineated, and it reveals different causes, combinations of elements of different types, features and elements of enrichment rules; all kinds of prospecting targets and mineralization vision division provides geochemical prospecting basis for the future; east-west multiple large area of stream sediment measurements, small-scale mapping anomalies may well reflect regional geochemical characteristics and regional metallogenic regularity, it plays a very important role to resolve regional geological questions and regional ore of the strategic plan; geochemical, geophysical prospecting combination of approaches, both the advantages of played geochemical quickly determine target, but also the use of strengths of geological work can accurately locate, coupled with appropriate surface project revealing,to get good prospecting effect. Based on the above study and combinning the discovered area of the geological characteristics of the deposit, we summarized the regional deposit metallogenic regularity and established metallogenic model.
