壳源 meaning in Chinese
shell source
Examples
- Granites belong to s - type granite , but the biotite granite was affected by the mantle or mantle fluid
黑云母花岗岩是壳源花岗岩但又受到幔源岩浆或幔源流体的影响。 - Detailed studies of tectonic unit and mineralized pedigree in each tectonic unit and each period provided that tectonic evolution passed an evolutionary sequence from early extension - transition - late compression that correspond to mineralization - sediment and submarine eruption - exhalation mineralization - moderate to acid magma and tectonic hydrothermalism that are relevant to mantle - derived magma and volcanic activities ; the mineralized pedigree can be indicated as mantle derived - inner basin and deep source - crust source ore - forming materials
对各时期、各构造单元的成矿谱系进行了详细研究，提出构造运动演化从早期拉张过渡晚期挤压的演化序列，分别对应于以幔源岩浆和火山活动有关的成矿作用沉积及海底喷流?喷气成矿作用中酸性岩浆及构造热液成矿作用；在成矿物质上由幔源盆内及深源壳源的成矿谱系。 - This paper emphasizes the effect of the dissolution of aluminosilicate during diagenesis may provide more radiogenic strontium which would result in a high content of strontium in carbonate rocks . so we should avoid the vein of carbonate and select the samples with less terrigenous clastic , less grain content and lacking calcite cementation collected as analysis samples . the microcrystalline limestone and micro - to fine - crystalline dolomite are rather fairly whole rock samples
作者还强调了成岩过程中由长石等铝硅酸盐溶解提供壳源sr所造成的碳酸盐矿物成岩蚀变可能表现为较高的sr含量；因此，在用全岩样品进行旨在反映海水组成的各种分析时，应回避碳酸盐脉，选择含陆源碎屑低、颗粒数量少、缺乏方解石胶结物的样品，微晶灰岩或微?粉晶白云岩是较为理想的全岩样品。
