岩化

Migmatization in Higher Himalayan Crystallines resulted from anatexis that took place at 22.67(/-0.60) Ma.

3高喜马拉雅结晶岩系的混合岩化现象是地壳深熔作用的结果。

The MT carbonates formed several stages and with complex origin, special in dolomitization, MT carbonate was in the form of calcite in epigenetic stage; This is the preliminary research fruit.

MT的形成具有多期性和复杂成因，在白云岩化中也有分布，MT在后生白云岩中依旧以方解石形态存在，这是初步研究成果。

The rock is chiefly marked by mixing of blocks of various ophiolite components of varying size and nature in mylonized matrix.

主要表现为糜棱岩化的基质中混杂着大小不一、性质各异的蛇绿岩各组分的岩块。

With the exception of rare, relatively well-preserved Phanerozoic shells, this happens to all carbonates.

排除那些稀少的，相对保存完好的显生宙shells，这种所谓的岩化过程基本会发生在所有的碳酸盐岩中。

Fault rocks, microstructures and homogeneous temperature (concentrated around 160℃) of fluid inclusions in the quartz veins shows that the fault belt mainly underwent shallow brittle deformation and the highest-grade dynamic metamorphic rock is mylonitized sericite phyllite.

显微构造、断层岩与石英脉流体包裹体均一温度(集中在160℃附近)均显示，断裂带以浅层脆性变形为主，最深动力变质岩仅为糜棱岩化绢云母千枚岩。

The matrix consists dominantly of mylonized volcanic rocks, tuff and strongly fragmented pyroclastic rocks.

基质主要有糜棱岩化的火山岩、凝灰岩和破碎强烈的火山碎屑岩。

The most frequent reaction causing the self-sealing of rocks with high secondary permeability is argillization.

这种发生频率很高的、使次生渗透性能良好的岩体产生自封闭现象的反应就是泥岩化。

Calculations based on Grosens'component-volume equation show that,wit the intensification of mylonitization,increasing amounts of SiO_2 and FeO are brought in,which is geologically expressed as intensified silicification and pyritization.

根据Gresens的成分－体积关系式所获得的计算结果表明：SiO＿2、FeO随着糜棱岩化程度加强而带入量增加，在地质上表现为硅化、黄铁矿化加强

Calculation of loss and gain of components in parentage and altered rocks during metasomatism, reveals that, in rubification and afforestation belts, the components brought in were K〓, CO〓, H〓O, and the components brought out were SiO〓, Ca〓 and Na〓, implying that the early ore-bearing hydrothermal fluids were rich in CO〓 and H〓O. SiO〓 brought out from potassic and chlorite alteration zones could serve as the main source for SiO〓 necessary in the formation of quartz veins, of silicification and of bericitization at shallow depth.

说明早期成矿流体为富含CO〓、H〓O等的碱性流体，其中钾化、绿化带中带出的SiO〓等是浅部石英脉、硅化、绢英岩化中硅质的主要来源，带出的Ca〓与成矿流体中的CO〓结合形成碳酸盐化，带出的Na〓则在浅部形成钠长石脉。

Therefore, the mudstone is rigidly hard in the dry state, but it swells and slakes easily when it absorbs water.

我国西南部泥岩由於成岩时间短、岩化程度低，乾燥时坚硬如石，遇水则易生回胀、崩解。

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.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
