生物成因的

It is shown that gas reservoirs described belong to large-scale self-generation and self-storage biogenetic gas and have good pool-forming conditions.

研究表明，该气藏属较大规模的自生自储型生物成因气，成藏条件良好。

They are different in the evolution of mineral, and microfabrics, which provides possibility to identify the origin of chert.

在夏鲁硅质岩中生物化石残骸内存在方英石和玉髓，为反演生物成因硅质岩的矿物演变序列提供了很好的证据。

Active fluid flow in the northern South China Sea makes both thermal gas and/or biogenic gas migrate into shallow strata and form hydrate in the gas hydrate stability zone. The fluid flow includes mud diapir and gas chimney structure.

南海北部深水盆地广泛存在的异常热流体活动促使深部的热解成因天然气或浅层的生物成因气运移到水合物稳定带，有利于水合物的发育。

There are some distinct geochemical differences between the organic and inorganic gases, mainly in chemical composition and the composition of isotopes.

无机成因天然气与生物成因天然气在地球化学特徵上存在显著的差异，主要表现在化学成分和同位素组成特徵。

The diversity of morphological features and the absence of modern analogies lead to a lively debate on the origin of the MT structure. Lots of models have been built to explain the formation of the MT structure, which can be grouped into two categories: the model of seismic-induced liquation and that of biogenetic origin.

由于形态多样且缺乏现代的类比物，国内外地质学家曾先后建立多种模式来解释其成因，这些模式大致可以归为两类：地震液化模式和生物成因模式。

TOF-SIMS images show bacteriogenic pyrites are relatively rich in Cu, Zn, and Ni, suggesting that bacteria probably play an important role in the enrichment of Cu, Zn, and Ni during their formation.

TOF-SIMS 的离子像亦表明菌落成因的黄铁矿富集 Cu 、 Zn 和 Ni ，表明菌落在生物成因黄铁矿的形成过程中，在改变介质条件、在迁移、活化和富集 Cu 、 Zn 等金属元素方面做出了贡献。

Oil and gas prospecting in the Qiongdongnan basin of the South China Sea indicates the potential of plenitudinous natural gases.

琼东南盆地油气地质显示盆地内具有生物成因和热成因天然气的巨大生成能力和远景。

In combination with seismic reflection features and probable gas resource discussion, it is concluded that there probably exist two kinds of reservoir models in the X Block. In the areas where faults or collapse structures develop, the gas resource is probably composed of thermogenic gas, gas hydrate is characterized by multilayer distribution, while in the inactive areas the gas resource is probably composed of biogenic gas, and gas hydrate is characterized by monolayer, which mainly distributes in a narrow zone on the surface of BSR (bottom-simulating seismic reflector).

结合地震反射特征和可能的气源讨论初步认为，X区块天然气水合物的成藏模式主要有两种类型：在断裂或滑塌构造发育区，水合物的气源以热解成因气为主，水合物呈多层分布；在构造平缓地区，水合物的气源以生物成因气为主，水合物呈单层分布，且主要分布在似海底反射之上一个狭窄的范围内。

Because of the special origin of biogenic gas, the evaluation of its source rocks is different from conventional hydrocarbon source rocks.

生物气成因的特殊性，使得对生物气源岩的评价也有异于常规烃源岩。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
