Researches on paleomagnetism and physical properties of rocks were carri-ed out along the Libixia profile in Hechuan area of Sichuan Province, withmore than 500 samples collected from Triassic Xujiahe Formation, LeikoupoFormation, Jialingjiang Formation and Feixianguan Formation. Remanent mag-netization and orientation, magnetic susceptibility and density were determinedfor 2200 samples. Heat demagnetization and alternation demagnetization wereperformed for all samples,and microscopic identification was conducted for partof the samples, indicating that magnetic minerals in major sedimentary rocksof this area axe magnetite and small amounts of pyrrhotite.The paleomagnetic measurements show that during Triassic the SichuanBasin continued to drift from south to north far away from the equator. AtEarly Triassic it was near 18.70°of Northern Latitude, and then reached26.68°, with the latter having a clockwise rotation of 30°relative to the form-er. It is noticed that vertical movement also took place during this period. Allthese data demonstrate that this area in Triassic lay in middle or low latituderegion favourable for formation of saline deposits, thus indicating an encouragingprospect for saline prediction in this area. In addition, strata in this area weredivided according to comprehensive data on physical properties of rocks.It is evident from the research work along the Hechuan profile that thestudy of paleomagnetism and physical properties of rocks is a very effectivemeans in the investigation of formation environment of saline deposits and incorrelation of strata, thus deserving of extensive application.
