查询词典 dolomitization

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。

In this deposit, ore bodies exist in the stratoid form and are c ontrolled by thrust faults. The host rocks are limestone in Bolila Formation of Late Triassic Jiezha Group and in Gadikao Formation of Early-Middle Permian Kaix i nling Group, with strong dolomitization and weak silicification. Minerals are ra ther simple and consist of sphalerite, galena, pyrite, calcite, dolomite and barite. The important ore textures are colloforms such as framboid and crust and xenom orphic grains, and the ore structures are in disseminated, brecciated, veinlike and lumpy forms.

东莫扎抓铅锌矿床矿体呈似层状展布，产状严格受到矿区逆冲断层的控制，赋矿围岩为上三叠统结扎群波里拉组灰岩和下-中二叠统开心岭群尕迪考组灰岩，发育强白云石化和弱硅化，矿物组合简单，主要为闪锌矿+方铅矿+黄铁矿+白云石+方解石+重晶石，矿石结构以皮壳状、草莓状等胶状结构和他形粒状结构为主，矿石构造为浸染状、角砾状、团块状和脉状。

The dolomitizing fluid was a mixture of magmatic hydrothermal, metamorphic hydrothermal, organic acid and regional brine under the ground. The Mg(superscript 2+) for dolomitization came from dissolution of magmatic rock, dehydration of clay mineral in the course of buried compaction.

白云化流体来自岩浆热液、变质热液、有机酸及区域地下热卤水的混合，白云化所需的Mg(上标 2+)来自岩浆岩中铁镁矿物的分解、埋藏压实过程中粘土矿物的脱水作用等。

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&。

马哈拉施特拉邦内政部高级官员Pradeep Indulkar称，有101人在冲突中丧生，287人受伤。

Mark Frei, a senior vice president of West, says 80% of West's homeagents have some college education, compared with 30% of those whowork in office-based call centers.

Frei说，该公司80%在家办公的人员都拥有本科学位，而在公司电话中心工作的人中只有30%拥有本科学位。
