红柳沟-拉配泉蛇绿构造混杂岩带中的斜长花岗岩野外地质、岩相学、岩石学、地球化学和锆石组成的综合研究表明,红柳沟斜长花岗岩为洋壳运移过程中含水条件下镁铁质岩石发生角闪岩相变质作用后部分熔融形成的;该类花岗岩锆石年龄代表了与洋壳扩张同期或者稍晚于洋壳扩张时代的洋盆的扩展时代;红柳沟斜长花岗岩LA-ICP-MS U-Pb年龄为(512.1±1.5)Ma,这一结果表明红柳沟-拉配泉有限洋盆的开启时限为中寒武世.
A comprehensive study on the field geology, petrography, petrology, geochemistry and zircon assemblage of the plagiogranite in the Hongliugou-Laizquanhe tectonic mélange zone shows that the Hongliugou plagiogranite is the migratory process of the oceanic crust The mafic rocks are partially melted by amphibolite facies metamorphism under aquiferous conditions. The zircon ages of these granites represent the expanse of oceanic basins in the same period as the oceanic dilatancy or later than that of the oceanic dilatancy. The LA-ICP-MS U-Pb age of the long granite is (512.1 ± 1.5) Ma, which shows that the opening time of the Hongliugou-Lazyquan finite oceanic basin is Middle Cambrian.
