Structural properties of the Longshoushan block： Constraint from LA-ICP-MS U-Pb zircon dating

Yan Haiqing,Liu Qiaofeng and Tang Zhongli、Fan Mochun、Wang Qiang、Ren Jianmei、Fan Chaofeng

Strategic Study of CAE 2015, Volume 17, Issue 2,   Pages 59-72

Abstract:

The samples were collected from Jinchuan continental scientific drilling core of 1 000 meters below.The geochemical analysis of variational basalts show that the distribution patterns of the rare-earth element(REE) were rich in light REE and the light and heavy REE fractionation significantly right mode. Trace elements show Rb， Ba， La， Ce， Nd， Sm， Nb， Ta are relative enrichment and Sr， Zr ， Hf are deficit. High Nb/Yb ratio， Th/Ta=1.7~5.63， Ta/Hf=0.10~0.21 ，which shows that the characteristics of continental rift basalt in the early time. We can conclude that Paleoproterozoic Longshoushan block is in the initial stage of continental block cracking. Zircon U-Pb isotopic ages indicate that the Longshoushan Block Baijiazuizi Group experienced at least three intense tectonic magmatic metamorphism event， period of peak events are respectively 2.1 Ga， 1.9 Ga and 1.85 Ga. Contrast of the tectonic evolution and stratigraphic structure of the Longshoushan block and North China plate， Yang Zi plate， Tarim plate and Western China Craton， we know that Longshoushan block has most similarities with Western China Craton. So the prospecting orientation for the Cu-Ni sulfide deposit in the future should be put in the whole Western China Craton.
