LITHOGEOCHEMISTRY AND SIGNIFICANCE OF THE XIDUIMIANGOU ROCK BODY IN JINCHANGGOULIANG, INNER MONGOLIA
摘要
Abstract
Lithogeochemical study shows that the Early Cretaceous Xiduimiangou rock body is typical high-Sr granite, characterized by high Al (14.51% to 16.57% of Al2O3, 15.434% in average), high Na (3.75% to 4.71% of Na2O, 4.313% in average) and high Sr (701×10-6 to 931 × 10-6 of St, averagely 802×10-6) contents, with severe H REE deficiency (21.07 -29.13 of (La/Yb)N, 23.54 in average), slightly negative or positive Eu anomalies and rich transitional elements. The rock body is likely related to the thinning of lithosphere in Eastern China. It is importantly significant for the research on the origin of magma in the northern margin of North China Craton.关键词
