火山岩

The volcano blowout material mainly is the gas, but likely the dregs and the ash massive volcanic rock and the solid matter have also spurted.

火山喷出的物质主要是气体，但是象渣和灰的大量火山岩和固体物质也喷了出来。

Some rocks from volcanoes break down to form black sand.

有些火山岩被撞碎后会形成黑色的沙。

Volcanic rock may become cap rock under certain conditions.

这使辽河坳陷存在多种与火山岩有关的油气藏。

As for the main reservoir -caprock assemblage, the Carbonifer volcanic rock is the reservoir while the Permian and Triassic mudstone is the cap rock.

主要的储盖组合是以石炭系火山岩为储层，二叠系和三叠系泥岩为盖层。

The geochemical studies of the basalts indicate crustal contamination increases from the inland to the coast along the volcanic belt, and therefore show different degrees of crustmantle interactions.

研究表明，该火山岩带自西向东表现出不同程度的壳幔相互作用，玄武岩在成岩过程中有少量陆壳组分加入。

Soil near the surface and eventually reached bedrock, the hardened lava of the Columbia Plateau.

洪水冲洗掉地表附近松软的风化土，最终到达了岩床，哥伦比亚高原上坚硬的火山岩。

The copper-bearing sulfide horizon of the Qinglongtan deposit underwent not only intense structural reformation but also superimposition of skarn-type mineralization after the formation of massive sulfide ores.

文章综述了柴北缘地区的VHMS型Cu-S矿床－青龙滩式矿床，指出其容矿岩石为加里东造山带中被改造过的岛弧火山岩，该矿床中含铜硫化物矿层形成后不但遭受过构造的强烈改造，而且也受后期矽卡岩化的改造和叠加。

The influential factors are: horizon, different system in strata sequence framework, clast composition, structure, matrix quality in source area, sedimentary facies belt, diagenesis, volcanics distribution and pressure distribution.

储层物性的影响因素主要有：层位、层序格架内不同体系域、碎屑组份、结构及物源区母岩性质、沉积相带、成岩作用、中基性火山岩分布、压力分布等。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
