HC fluid may be generated indirectly in bottom sediments of water basins of riftogenic type under sufficiently high heat flow that do not require submersion of original oil and gas source mass at the depth of 3 km and more (riftogenic model).
指出,烃类可通过各种途径生成:烃类的生成不仅遵循传统的沉积-运移理论,而且也可生成于裂谷型底部含水沉积盆地中,当有相当高的热流时,生烃岩不需要沉降到3km以下就能生烃;在全球油气生成过程中,不能排除烃类由矿物合成的可能性;无机合成的烃类成分主要为甲烷,而生成现今的石油还需要有有机质和其他有效催化剂的加入才行,可见,石油和天然气的生成是多源的。
The Liaohe Group of Paleoproterozoic Erathem located in rift basin of east Liaoning and south Jilin area ,a boron-bearing Rock series which is divided into thress part from the up to bottom of this group and separatedly locate with szaibelyite--suanite ,magnetite bearing szaibelyite and ludwigite types of boron deposits.

对岚皋地区辉石玢岩岩石化学和地球化学研究表明,本区辉石玢岩为碱性玄武岩系列;不同期次活动的辉石玢岩为同源岩浆在不同阶段上演化的产物;演化趋势属跨越B型,本区辉石纷岩形成于板内稳定区,是早古生代南秦岭被动大陆边缘裂谷的岩浆活动时的产物,该裂谷扩张速度与东非埃塞俄比亚相近。
n this thesis, the author discussed the basic pattern of rifts in Taiwan Strait, anddivided the strait and its both sides into four rift systems, analysed the formation andevolution processes of the rift systems, explained the corresponding relation of the formation and evolution between the rift structure and rift valley, and studied the evolutionmodel of Taiwan Strait rift valley.
论述了台湾海峡新生代断裂构造基本特征,划分出海峡及两侧两大断裂系,探讨了断裂系的形成演化过程,阐明了断裂构造的形成演化与海峡裂谷演化的对应关系,并进一步探讨了海峡裂谷的演化模式。

The author inversed the stepwise evolution of Zhongtiao rift by analyzing Precambrain sedimentary formation,magma formation and tectonic form of the Zhongtiaoshan-Wangwushan region and discussed the perfect mineralization conditions of the Wangwushan region formed in the evolution of the Zhongtiao rift and regional crust.
对中条—王屋山地区前寒武纪沉积建造、岩浆建造、构造形态的分析后,反演出中条裂谷的递进演化过程,认为王屋山地区在中条裂谷和区域地壳的演化过程中形成了极为有利的成矿条件:①形成多层含矿建造;②通达地幔的深大断裂提供了丰富的矿源和成矿空间;③频繁的岩浆活动补充了矿质并提供了成矿热能;④剥离断层系统进一步提供了扩容空间;⑤以活化转移为主要机制的强烈变形变质作用对已形成的含矿建造(矿源层)进行改造。
The reservoir sedimentation models are classified into rift model and sag model,which are fully represented in the passive rifts and active rifts,only different in sedimentary cycles that the active rift is bi-model with single cycle and the passive rift is bi-model with multi-cycle.
裂谷盆地的储层沉积模式主要分为断陷式和坳陷式,他们的沉积分异无论是在主动裂谷或是被动裂谷中都有充分体现,区别只在于沉积旋回上的差异,主动裂谷储层沉积为双模式单旋回;被动裂谷储层沉积为双模式多旋回。
Two extreme modes of reservoir sedimentation: Active rift and passive rift;
储集层沉积的两种极端模式——主动裂谷和被动裂谷
One is that,by the shove of passive rift valley polycycle,quartz sandstone with high maturity of lithologic composition deposits on the background of sub-plain during sag period;together with the rock formation environment of paranormal saltless local water,the reservoir characterized b.
厘定该盆地这种突出商业价值的地质因素主要表现在以下两个方面:1)被动裂谷的多旋回推移,在坳陷期的准平原背景下沉积了高岩石成分成熟度的石英砂岩,加之超淡地层水的成岩环境,最终形成盆地的高孔高渗储层;2)“教科书”式的生储盖组合。
The geological mechanism of high quality reservoir in Muglad basin is due to its particularsedimentary-tectonic background--passive rift.
研究表明,Muglad盆地优质储层发育的地质机理在于其独特的沉积构造背景--被动裂谷。
