1. The results of this paper show:(1) The Upper Triassic Sanhedong Formation deposited in limited carbonate platform sedimentary environment of shallow marine; the temperature of paleo-sea water is mainly from 26.7℃～32.1℃, which indicates Lanping Basin located in the hot tropics during formation of the Upper Triassic Sanhedong Formation.(2) The provenance tectonic setting of sedimentary rocks from the Lanping Basin are represented by passive continental margin and continental island arc and the original source rocks were all derived from the upper continental crust, with felsic rocks dominant. So the Lanping Basin is a typical continental-type basin.(3) The evolution of Lanping Basin have undergone three different prototype basins'evolution, i. e. rift basin, depression basin and strike basin.(4) Ore-forming materials of deposits in large ore-assembly district were derived from crust (mainly from basement and stratum of basin ore-forming fluids were hot brine of basin dominant and the organic matter from source rocks of basin stratum has involved in mineralization; and mineralization epoch of deposits was about 56Ma or 30Ma, which are compatible with the times of collision of Indian plate and Eurasian plate and late strong compression stage respectively.
