地槽阶段，火山作用及风化沉积作用等形成了巨厚的硅铝质地槽构造层；重熔或混熔（包括混合作用和/或同化混染作用）形成了加里东花岗岩类。

Geological and geochemical features suggest that the bimodal volcanism took place in rift setting of continental margin, basic magma originated from not strongly depleted mantle, and rhyolite derived from the original melt formed by partial melting of granulite facies orthometamorphite in lower crust.

地质和地球化学特征指出吕梁群上部的双峰式火山岩形成于大陆边缘的裂谷环境，其中的玄武质岩浆起源于亏损程度较低的上地幔，并受到了陆壳物质的混染。酸性端元是由下地壳麻粒岩相正变质岩的部分熔融形成。

Flash heat, volcanism, lightning, wind, and waves all renew the material world.

Tectonic activities and volcanism in the basin have an influence on hydrocarbon generation of kerogen and its change.

盆地构造活动和火山作用可以促进干酪根的成烃转化。

Such sedimentation followed a 20~25 Ma-long period of Tiaojishan/Lanqi volcanism and was accompanied by plutonic emplacement (ca.158~141 Ma) in some Yanshan areas.

土城子组/后城组的沉积是紧随着在燕山部分地区发生的，持续了20~25Ma的髫髻山组/蓝旗组火山及岩浆活动。

Taking the eastern sag of the Liaohe basin where coal, oil and gas resources coexist and the Wangying borefield of the Fuxin basin where coalbed gas was first discovered, researched and developed in China as examples, we systematically discuss the control of volcanism on the lateral and vertical distribution of brown coal, flame coal and gas coal in the third member of the Paleogene Shahejie Formation and on the gas source conditions of each coal region. Both the methane released in the process of regional plutonic metamorphism and the additional methane generated by contact metamorphism are calculated. The physical properties and storage capacity of the coal beds changed greatly due to the formation of blackcoal and highlymetamorphosed crevice coal from igneous intrusion. The sealing capacity of intrusions with various occurrences such as dikes is highlighted.
