The Application Study Of The Synthetic Method Of Geophysics-geochemical Exploration In Prospecting Of Greenstone-type Gold Deposit In Daqingshan, Inner Mongolia

In this paper the author introduced the application of the synthetic method of geophysics-geochemical exploration in prospecting of greenstone-type gold deposit in Daqingshan, Inner Mongolia. Take examples for Youlougou, Xindigou, Halaqing gold ore districts ,the author detailedly discussed the strata, magmatic rocks, alteration, main metallogenic factors, mineralization characterization, physical prosical, IP anomaly, magnetic anomaly and pedogeochemical anomaly in ore district. On the base of summing up indications and guides of the geology, geochemistry, geophysics, application effect and application condition of synthetic method of geophysics-geochemical exploration have been summarized by the analysis of application of synthetic method for exploration greenstone-type gold deposit in Daqingshan area.The analysis and contrast of the practical measured data for each gold ore district shows that using the synthetic method of geophysics-geochemical exploration to prospect the greenstone-type gold deposit is valid. The big scale stream sediment survey or geochemical soil survey can contract mineral prospecting target in the area of regional geochemical anomaly. With superficial (or profile) geophysics-geochemical exploration it is availably to circle the distributing scope of orebody , and to make sure the form of orebody, strike of orebody, and dip of orebody. So the synthetic method of geophysics- geochemical exploration can direct verification of drilling exploration, and get the purpose of prospecting concealed or half concealed gold ore body, and provide the method and means for prospecting of greenstone- type gold deposit in similar area.
