岩化

Based on field work in fourteen typical ore districts of China, the author made experiments on contact metasomatism of ultrabasic-acid intrusive rocks with carbonate rocks, interaction between volcanic pneumatolyto-hydrothermal solution and volcanic rocks, and metasomatism in the process of sedimentary metamorphism and migmatizatiun.

本文作者在全国14个典型矿区的野外工作基础上，进行了超基性-酸性侵入岩与碳酸盐岩的接触交代实验；火山气热液与火山岩的相互交代实验；区域沉积变质和混合岩化过程中的交代作用实验。

The magmatism of Yanshan period caused wide magmiting, the tectonic sealing obscured the primary mylonite.

燕山期的岩浆热活动，在造山带轴部产生广泛的混合岩化，构造热愈合使糜棱岩转化为构造片岩。

New relations of minerals, mineral paragenesis and replacement have also been found.

在岩石学研究方面，找到了霓长岩，发现了霓长岩化作用，确定了火成碳酸岩岩石的存在。

This rock contained chalcedonic cement before it underwent diagenesis, a process where low temperatures and low pressures alter the content of sediments before they finally lithify, or turn into rock.

这块石头包含石髓的水泥之前，它经历了岩化作用，一个过程，那里的低温和低的压力，改变的内容，沉积物之前，他们终于岩化，或变成岩石。

The original Seluohe Group contains at least four parts: Late Archean metamorphic rocks (zircon SHRIMP protolith ages 2517~2534 Ma), Late Paleozoic metamorphosed volcanic-sedimentary strata (zircon SHRIMP 252 Ma), Permian gneissic granitic complex (zircon SHRIMP 260 Ma), and Jurassic mylonitized granites (zircon SHRIMP 168 Ma).

原划分的色洛河群至少由4部分组成：新太古代变质火山－沉积地层（锆石SHRIMP年龄为2517~2534 Ma）、晚古生代变质火山－沉积地层（英安岩锆石SHRIMP年龄为252 Ma）、二叠纪片麻状杂岩体（锆石SHRIMP年龄为260 Ma）和侏罗纪糜棱岩化花岗岩（锆石SHRIMP年龄为168 Ma）。

In ore body, K-feldsparization is widely distributed, silication ispockety, the other alterations have obvious vertical zoning, from upper to lower is:biotite zone→sericite zone→propylitic zone (epidote-chlorite-calcitization zone).

在空间上，钾长石化分布较广，硅化分布不均，其它蚀变垂直分带现象比较明显，由下至上是：黑云母化带→绢云母化带→青盘岩化(绿泥石-绿帘石-方解石化)带。

The mineralization-alteration in Shuangfengshan appears in downward succession of silica breccia zone, low grade gold-bearing silica rock zone, quartz stockwork zone, pyrite montmorillonite zone and propylitic alteration zone.

这两个成矿阶段同源同位的蚀变矿物晕叠套，造成双峰山矿床蚀变分带从上至下为隐爆矽质角砾岩化带、低金品位矽质岩带、石英网脉带、黄铁矿蒙脱石化带和青磐岩化带。

The cave was vertically developed in dolomitite and dolomitized limestone and controlled by a fracture zone in the Baojing-Fuxing area. The formation of the cave is closely related to the special geological tectonic environment.

洞穴发育在保靖－复兴断裂带的裂隙破碎构造控制的白云岩、白云岩化灰岩残体中，是断面陡转缓地段的垂向洞穴，成洞原因与所处的特定地质构造环境有关。

Therefore,the northern Sulu UHPM zone can be divided into four petrological tectonic units from southeast to northwest:Haiyangsuo metamorphic complex (eclogitized crystalline basement of the Yangtze craton),Rongcheng UHPM complex,Weihai metamorphic complex (granulites retrograded from UHPM eclogites) and Kunyushan boundary metamorphic magmatic complex.

由此笔者将苏鲁变质带北部由南向北划分为海阳所变质地块（榴辉岩化扬子陆块基底变质单元）、荣成变质地块、威海变质地块（麻粒岩相叠加变质的超高压构造岩片）、昆嵛山边界杂岩带。

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。
