苏米尔盆地中新世海滩岩及沉积环境探讨

对苏米尔盆地布阶下、上段生物屑灰岩的野外观察和实验室岩石学、矿物学、沉积学综合分析结果表明:这些岩石具潮间带和陆上渗流—潜流带胶结特点,其沉积环境为亚热带—热带中至较低能量港湾式海滩,岩石中陆源碎屑来源于邻近区域沉积岩和较远的阿尔卑斯变质岩。

Miocene Beach-rocks in the Sommieres Basin and Their Paleo-environmental Approch

Field observation and laboratory comprehensive analyses in petrology, mineralogy, sedimentology of the bioclastie limestones in lower and upper Burdigalian in the Sommieres basin show: the rocks appear the special, propertys of intertidal, continental vadose and phreatic cimentations; the depositional environment was a bay-beach in the subtropic-tropic zone with moderate-lower wave energy; the terrigenous detritus came from the sedimentory rocks in adjacent areas and the metamorphic rocks in the Alpes.
