Seven molybdenite samples from greisen ore body and quartz vein tungsten ore body associated with black tungsten ore were chosen for Re-Os isotopic dating and model age of (141.4±2.2) Ma~(158.2±2.2) Ma were obtained. The isochrone age of molybdenites from greisen type tungsten-tin ore body is (156.8±3.9) Ma, which indicates that its mineralogenetic epoch is at the Middle Jurassic, corresponds to the second stage of early Yanshanian period. And the model age for the samples from greisen ore body and from quartz vein ore body are (150.7±2.4) Ma~(158.2±2.2) Ma and (141.4±2.2) Ma~(151.0±2.4) Ma respectively, which indicates that the mineralization time of the quartz vein ore body is slightly earlier than that of greisen ore body.

In this paper, with 2-oxo-propionic acid salicyloyl hydrazone as a ligand, one calcium complex, three copper complexes and thirteen rare earth(RE=La, Ce, Pr, Nd, Sm, Eu. Gd, Tb, Dy, Er, Tin, Yb and Lu) complexes have been synthesized. The crystals of four complexes were obtained, and the crystal structures were determined by single crystal X ray diffraction. One of the crystals is calcium complex, the other are binary and trinary complexes of copper.
