StructureExtensive Disjunctive Faults Striking Ne To Nw, Brecciated, Banded, And Cockade Structures - A Result Of Repeated Crushing And Opening Of Ore Enclosed Joints; Less Frequent Crustification, Drusy, And Collomorphic Structures.
Tectonic settingThe Darasun Deposit Is Located Within The Eastern Transbaikal-Paleozoic Fold Region, Gold-Molbdenum Metallogenic Belt, In A Tectonically Disturbed Mobile Block Of Old Gabbroic And Hybridized Rocks Which Are Surrounded By Granitoid Rocks (Less Susceptible To Deformation), And Bordered By Extensive Zones Of Faults With Northwesterly Strike.
AlterationRepeated Hydrothermal Alteration Including Chloritization, Sericitization, Carbonatization, Pyritization, Tourmalization And Listwanitization.
