THE CHARACTERISTICS OF GEOLOGY,GEOPHYSICAL AND GEOCHEMICAL PROSPECTING AND PROSPECTING PATTERN OF LAOWAN GOLD ORE BELT IN TONGBAI COUNTY

Laowan gold ore belt is a primary gold mineralization belt of the tectonic altered rock type in the Tongbai-Dabie region.On the basis of analysis and study of ore-forming geological settings,geophysical and geochemical features of the ore belt,the authors have established the prospecting pattern and criteria,for the purpose of guiding ore prospecting and raising the research level and ore prospecting effect of the zone.By way of the work of establishing prospecting pattern and evaluating criteria of overall prospecting,the desired results have been achieved.
