摘要
Multiple Inverse Method is useful for separating stresses from heterogeneous fault-slip data.By using the method applied to fault slip data in the Yongping Copper Deposit,three phases of palaeotectonic stress were found since the Indosinian.At first,E-W direction of compressive stress field formed S-N direction of folds,faults and interlayer fracture zone.Then the tectonic stress field transformed as NW-SE direction.Accompanied by the intrusion of pluton,thermal metamorphism occurred on interlayer fracture zone.Hydrochloride rock changed into skarn and mineralization.At last,E-W direction of compressive stress leads to increasing nappe distance.As a result,migmatite and skarn thrust over Paleozoic strata from east to west.
