摘要
盆地流体是近年地学研究的热点之一。按照成因 ,盆地流体可以划分为内部流体和外部流体两大类。盆地流体的驱动机制包括压实驱动、重力驱动和密度 (热对流 )驱动三种机制 ,其基本特征及岩石学记录各有不同。压实流动可产生蒙脱石的脱水转变和砂泥岩处的物质转移 ,大气水流动以矿物溶解和沉淀为特征 ,热对流的成岩作用主要涉及那些溶解度对温度变化敏感的矿物。
Basinfluid is a popular topic in basin analysis. The basic type of basinfluid is divided into intra fluid and extra fluid in terms of their genesis. The drive mechanism includes three types: compaction drive, gravity drive and density(heat convection)drive. Their foundational features and lithological information are very different. The flow of compaction produces dehydration of smectite and material transport in sandstones and mudstones.The flow of meteoric water characterizes mineral dissolution and precipitation. The diagenesis of heat convection refers to sensitive mineral to solubility varying with temperature.
