简介：碳和氢源於生物的气体的同位素的作文为它的产生小径和reservoiring特征的学习是很重要的。在这篇论文，在中国的源於生物的煤气的水库的形成小径和reservoiring特征以碳和氢被描述从10座源於生物的煤气的水库的31件煤气的样品的同位素的作文。学习表演氢这些源於生物的煤气的水库的同位素的作文能被划分成三间隔：δ>−200‰，−250‰<；δ<-−200‰和δ<−250‰。先进相信在新鲜的水是的大陆人的条件下面的源於生物的气体的主要产生小径醋性的发酵。我们的研究结果证明在海洋的外形的条件下面的源於生物的气体的产生小径是典型公司2-减小，源於生物的气体有重氢同位素的作文：它的δ价值比−200‰高；在大陆人外形的条件下面的源於生物的气体被一样的方法，而是它的氢也产生同位素的作文比简历，基因气体在典型海洋的外形状况下面产生了轻：−250‰<；δ<−200‰，δ价值可能与在古老的湖的水媒介的咸度有关。从Qaidam盆的相关数据，这能被看见源於生物的甲烷的同位素的作文有的氢有增加水的咸度的一样的变化趋势中等。有源於生物的煤气的水库，在大陆人外形的条件下面在过渡区域形成。这些煤气的水库是源于公司2-reduction和醋性的发酵，其形成可能与中等的古老的水和相对高的地热的坡度的非变体的咸度有关，盒子在Baoshan盆被遇到。在这些区域产生的源於生物的气体有轻氢同位素的作文：δ<−250‰，和相对重的碳同位素的作文。在碳之间有相当强壮的否定关联同位素的作文和氢同位素的作文。产生机制和碳的小径，和氢源於生物的气体的同位素的作文可以被用来查明从自然界的源於生物的煤气的样品是否具有�

简介：相当在Gaoqing-Pingnan断层带的环境被开发很多座煤气的水库。把作文基于气体，他们能被划分成二个组，即，CO2和CH4。他们的作文和同位素地球化学在这研究被处理。CO2内容从60.72%-99.99%，从-3.41per的三角洲~(13)C_(CO2)价值千---9.8per千，并且从4.35xl0~的3He/4He比率(-6)-6.35xl0'6(即R/Ra=4.45-4.35)。在作文和同位素地球化学上基于数据，深地质的背景，深断裂和火山岩，它被看在Gaoqing区域散布的那CO2，主要从披风来源发源与magmatic被联系的无机的物质。为CO2水库的形成的有利构造环境是裂缝，它与大fault-magmatic活动，CO2煤气的水池的形成和他们到最近的magmatic活动的时空关联有关。烃煤气的水池发生在Huagou区域。CH4内容在88.83%-99.12%的范围以内，并且三角洲~(13)C_(CH4)每千珍视-44.7--54.39每千。这显示烃气体在高温度源于油类型气体的分解。在CO2煤气的水池的火山岩--并且CH4煤气的水池分布式的区域在Fe2O3和FeO内容显示出重要差别。这证明了烃气体可能源于各种各样的化学反应。Magmatic活动是为在Gaoqing-Pingnan断层带的CO2和CH4气体水池的分发的主要原因。
