介绍了热对流产生的条件与地质背景 ,指出火成侵入体、盐丘和活跃断层周围等温线陡倾斜场所易发生热对流成岩作用。综述了岩浆成因热对流的岩石学记录 ,包括热变质作用、突然升温—逐渐降温的自生矿物组合和相对高温的自生矿物类型 ,分析了自生伊利石的 K/Ar年龄在热对流成岩作用研究中的作用。阐述了热对流成岩作用对盆地动力学、砂岩储层和油气运移研究的意义。 The condition of convection and its geological background are introduced. It is pointed out that thermal convection and diagenesis are likely to occur in intrusive bodies, salt domes and steep slopes around the active faults. The petrological records of thermal convection of magmatic origin are reviewed, including thermal metamorphism, abrupt warming, gradual cooling of authigenic mineral assemblages and relatively high-temperature authigenic mineral types. The K / Ar ages of authigenic illites are analyzed in the study of thermal convection diagenesis Role. The significance of thermal convection diagenesis on basin dynamics, sandstone reservoirs and hydrocarbon migration is expounded.
