摘　　要：盆地构造活动和火山作用可以促进干酪根的成烃转化。构造活动的影响表现在力化学作用上 ;火山活动的影响除了表现为加热作用外 ,还表现为与火山岩有关的矿物与有机质或干酪根的相互作用 ,包括催化和加氢作用。黄铁矿被证明是一种更有效的催化剂。这些影响是附加在正常的干酪根热解作用上 ,而且构造活动和火山作用的影响也是复合在一起的。一些模拟实验证实了上述作用的存在以及对于不同的干酪根类型所施加影响的程度是不同的。Tectonic activities and volcanism in the basin have an influence on hydrocarbon generation of kerogen and its change.The influence of tectonic activities focuses on a process of mechanochemistry,while the influence of volcanism is presented by interaction between volcanic minerals and organic matter including catalysis and adding of hydrogen into hydrocarbon.It is known that pyritet is a more effective catalyst.All those influences are exerted on the normal process of thermal degradation of organic matter or kerogen,with the influences of both tectonics and volcanism mixed with each other.Some simulations have proved the influences mentioned above and also the different influence degrees for different types of kerogens.
