查询词典 dolomite

Many dolomitization models have been invoked to interpret the origination of virious diagenetic dolomites. However, the genesis of earlyformed dolomites has long been an enigma in sedimentology, often referred to as the "Dolomite Problem".

白云岩的成因是沉积学界倍受关注的研究主题；众多的白云岩化模式可以用来解释各种成岩白云岩的成因；然而原生白云岩的成因一直是困扰沉积学界的难题，被称为"白云岩问题"。

All these evidences indicate that the dolomite is resulted from dolomitization due to mixture of sea water with fresh water from the penesyngenetic period to the early diagenetic stage in the environment of intertidalsubtidal zone of continental sea.

该地区的白云岩成因为潮间—潮下环境下的准同生期—成岩早期海水—淡水混合白云岩化作用形成的结果。

Major factors that have impact on the dolomite reservoir quality are originalsedimentary facies, dolomitization degree, dolomitization type, development degreeof tectonic fissure and property and intensity of deep burial corrosion.

影响白云岩储层质量的主要因素为：原始沉积相带、白云石化程度、白云石化类型、构造裂缝的发育程度和深埋溶蚀作用的性质和强度。

Feixianguan Formation of lower Triassic is an important reservoir, which mainly consists of the dense oolitic dolomite and limestone altered by the late dolomitization of oolitic bars.

四川盆地东北部的三叠系下统飞仙关组是重要的油气储层，其储集岩体主要为经晚期白云岩化改造的鲕滩坝沉积的致密鲕粒白云岩、鲕粒灰岩。

It is difficult to explain the origin of crystalline dolomite by traditional dolomitization mechanisms. The diagenesis of the Feixianguan carbonates should be governed by some kinds of marine fluids rich in strontium and poor in manganese.

具有海源色彩的高锶、低锰成岩流体在很大程度上控制了飞仙关组碳酸盐的成岩作用，其来源与成因值得进一步关注，控制其运移、封存和发生水—岩反应的时空机制有待回答。

The origin of dolomites is a research topic attracting great attention in sedimentology. Many dolomitization models have been invoked to interpret the origination of virious diagenetic dolomites. However, the genesis of earlyformed dolomites has long been an enigma in sedimentology, often referred to as the "Dolomite Problem".

白云岩的成因是沉积学界倍受关注的研究主题；众多的白云岩化模式可以用来解释各种成岩白云岩的成因；然而原生白云岩的成因一直是困扰沉积学界的难题，被称为"白云岩问题"。

However,very low Mn contents(average 19.8ppm),relatively high Sr contents(average 137ppm)and the homogenization temperatures measured in fluid inclusions of crystalline dolomite do not support the hypothesis that meteoric water as high as 94% involved the dolomitization.

但极低的锰含量、相对较高的锶含量和包裹体均一化温度等资料均不支持有94%的大气淡水参与了结晶白云岩的白云石化作用，其白云石化流体应是埋藏成岩过程中囚禁的近同期、但是非同期的海源流体，其来源可能与埋藏成岩过程中该时间段蒸发盐的溶解有关。

TheJiyang depression located in paleomonsoon climate zone in the period of the sahejieformation sedimentation, the wet and hot climate made ancient lake become deeperwater, enhanced stratification, reduced primary productivity of plankton, decreasingsedimentary velocity of carbonate, increasing sedimentary velocity of clay, fortifiedreductibility on certain degree, and then would be available for development of blackshale, dark shale and oil shale; In the contrast, the cold and dry climate lead ancientlake to shallower water, subdued stratification, increaser primary productivity ofplankton, enhancive sedimentary velocity of aphanitic carbonate, decreasedsedimentary velocity of clay, and then would be available for development calciteshale, calcite laminar shale, calcite mudstone, shaly carbonate rock, even laminarcarbonate or dolomite rock.

济阳坳陷在古近系沙河街组沉积期属于古季风气候带，在湿热的气候条件下古湖水加深，分层性增强，浮游生物的古生产力降低，隐晶碳酸盐的沉淀速率变小，粘土沉积速率加快，还原性一定程度上有所加强，有利于黑页岩、油页岩和暗色泥岩的形成：而相对干冷气候下，古湖水变浅，分层性减弱，浮游生物的古生产力增高，隐晶碳酸盐的沉积速率变大，粘土的沉积速率减慢，有利于钙质页岩、钙质纹层页岩、钙质泥岩、泥灰岩甚至纹层状碳酸盐岩、灰岩的发育。
