摘要
The Yinglingshan granite, which is mainly distributed in the southeast of the seat of Yishui County, is one of the most important component parts of the Neoarchean Yishui magmatic complex. The granite is intruded into the Yishui Group-complex composed of a metamorphic rock association of two-pyroxene amphibolite - biotite-plagioclase fine-grained gneiss – two-pyroxene-plagioclase gneiss, and its northern margin is in contact with the Mashan, Xueshan and Dashan granite bodies, while its southeast part is in contact with the Linjiaguanzhuang rock body. The rock is medium to coarse-grained and slightly gneissoid and contains abundant xenoliths. The zircon SHRIMP U-Pb dating of samples YS06-30 and YS06-48 yield 2530±7 and 2531±8 Ma, respectively, indicating a Neoarchean age.
