国外天然气地球科学研究成果介绍与分析——以索科洛夫的著作为主线

INTRODUCTION AND ANALYSIS OF FOREIGN NATURAL GAS GEOSC IENCE STUDIES BASED ON SOKOLOV'S DATA

考虑到前人对生物成因天然气来源和泥质岩、碳酸盐岩、煤等作为气源岩问题已有相当深入的研究,文中不再涉及。文中将从更深的气源(例如中、下地壳火成岩、变质岩甚至地幔岩)角度对国外有关科研成果和资料加以搜集和整理(以前苏联学者ВА索科洛夫的著作为主线)[1-2]①,做出了以下分类并进行了力所能及的分析:①火山气;②热泉气、气泉气和冷泉气;③火成岩气;④金属矿床气;⑤盐层气;⑥石油伴生气;⑦煤层气;⑧泥火山气;⑨地下水中气;10断层气和地震气;11韧性剪切带气;12地幔气。有关资料年代尽管有些久远,但仍希望对现代研究有所启示。

On the basis of Cоколв＇s data, this paper summarizes aspects of the following gas distribution in crust and upper mantle, such as volcanic gas, hot spring and fumarole gas, igneous gas, ore deposit gas, salt gas, associated gas, coal bed gas, mud volcanic gas, ground water gas, fault and earthquake gas, ductile shear zone gas, and upper mantle gas. Numerous surveillance data has revealed that the gas abundance in igneous rocks is no less than that in the sedimentary ones.
