Abstract:

The work area is located in the Li(county)-Min(county)metallogenic belt where the layer system developed completely,the Lithology combination mostly interblended sandstone and slate which in favor of the migration and preservation of gold mineralization,additionally,folds and faults controlled the spatial orientation and distribution of ore deposits.There is a close relationship between activities granite and Au metallogenic,as well as dikes and veins in the areas.At the same time,the gold mineralization and hydrothermal activities also have a close relationship.The various types of hydrothermal alteration is very well developed,and the hydrothermal alteration which closely related to the Au variable is mainly alkali metasomatism,pyritization,silicification,carbonation,limonitization etc.Anglicizing the stratum,structure,magmatic and metamorphic conditions and combined with the research results of the mineral deposit,the geochemical and the remote sensing in the region,3 mineralization targets (Taerli,Biekungou,and Beimengou)were predicted.

Key words: metallogenic conditions, metallogenic prediction, Lixian-Minxian gold belt, Gansu Province
