Tectono_lithofacies and Forecasting of Gold Deposits in Songpan Area
Abstract:Complicatecl tectono_lithofacies assiciations were formed during the Late Indosinian orogeny in Songpan area.Gold deposits occurred in the Triassic system were compositely acted by source beds,polystage structural deformation and magmatic heat fluid,and have polygenetic feature.The ore_controlling significance of NNE_trending structural_minerallizing belts should have attention in prospecting mineral deposits.
