The Tuwu–Yandong belt contains five porphyry Cu deposits (Fuxing, Yandong, Tuwu, Linglong, and Chihu), constituting the largest metallogenic in Northwest China. However, framework for remains controversial. Rhenium-osmium dating of molybdenite from Chihu comparisons with previous geochronological data suggest that two episodes (335–330 Ma 323–315 Ma) Cu–Mo mineralization occurred belt, metals w...

In the course of geological prospecting fulfilled with participation FGBI TsNIGRI within Chayangro ore cluster Dodykhta-Uryakh region in southeastern Baikal-Patom metallogenic province, Dzhalagun lode gold prospect field same name was studied and its economic significance has been proved. It substantiated that is closely similar to typical deposits Bodaibo sense formation phasing, character hyd...

Luku alkali syenite is distributed throughout the southern end of Hongge basic-ultrabasic intrusion in Panzhihua, Sichuan, SW China. Using LA-ICP-MS, yielded a zircon U-Pb age 264.5 ± 1.6 Ma, concordant with ages E'meishan large igneous province (260 Ma). The displayed silica-saturated, Al-adequate and alkali-rich signatures, SiO2 62.07%–64.04%, Al2O3 16.26%–16.79% Na2O + K2O 9.17%–9.91% (avera...

We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...
