地槽区

沉积韵律：地槽区的韵律通常为海相，每个韵律的厚度较薄，一般为几厘米至几十厘米。

Sedimentary rhythms : Sedimentary rhythms of geosynclinal region are of mostly marine facies , and each rhythm has a small thickness of several to dozens of centimeters .

在Blatt等（1972）图解中，落入优地槽区。

祁连优地槽区块状硫化物矿床形成地质环境的初步对比研究和探讨

A preliminary investigation into the ore forming environment of the massive sulfide deposits in the Qilian eugeosyncline

清河镇动物群的存在说明我国北部地槽区早古生代早期的一次重大生物事件。

The discovery of the Qinghezhen fauna shows that during the Early Palaeozoic there occurred a significant event in the North China geosyncline .

上述特点的产生受新疆北部晚石炭世古海西地槽区发展演化的控制。

The characteristics mentioned above are controlled by the development and evolution of the northern Xinjiang Hercynian geosyncline region of Late Carboniferous age .

其金的成矿地质背景复杂，主要可分为变质基底区、地槽区、盖层区、中生代火山断陷盆地、构造－岩浆活动带5种类型。

There are 5 kinds of geological settings : metamorphic basement area , geosyncline area , cover area , Mesozoic volcanic fault basin and tectonic magmatic active belts .

依照地质环境，南岭花岗岩可分为4类：1、地槽区花岗岩；

According to geological environment , Nanling granites may be tentatively classified into four kinds . 1 . granites of geosyncline region of which two types have been found .

四川攀西地区地处我国东部地台区和西部地槽区的接合部位，是著名的攀西裂谷所在地；

The Panxi Area in Sichuan province is situated at the joined place between east platform area and west geosyncline area of China , and in where there is the famous Panxi rift .

以上事实说明华北地台区富碱侵入岩的物质来源与富集地幔关系密切，而地槽区的则与亏损地幔关系密切。

All those facts above show that source material of the alkaline-rich intrusions in North China platform has close relationship with the enriched mantle and that of the geosynclinal area has close relationship with the depleted-mantle .

随后大洋底板活动的减弱，则招致褶皱陆壳的剥蚀，并伴有广泛展布的玄武岩岩浆作用，以及大洋周边优地槽区的稳定化。

The following decrease of the oceanic floor spreading activity results in degradation of folded continental crust , accompanied by wide extending of basalt magmatism and stabilization of eugeosyncline regime on the peripheries of the oceans .

一方面，它虽由历史大地构造单元如地槽区、地台区和地洼区组成，但强调了在空间上迁移的动态而与之有别；

On the one hand , though consisting of historic tectonic elements such as geosynclinal , platform and geodepression ( diwa ) regions , it puts emphasis on their changing state in spatial migration , thus differing from them .

由地槽区、地台区、地洼区的地球化学特征及其发展和演变过程，可见地球物质的地球化学分异是引起地壳大地构造运动和发展的基本原因之一。

It is thus obvious that the geochemical differentiation of the earth 's material is one of the basic causes of tectonic movement and crustal development , as evidenced by the geochemical features and their development and evolution process in geosynclinal , platform and diwa regions .

中华地台与兴蒙古生代地槽褶皱区界线的重新厘定

Redetermination of the boundary between Chinese platform and Da Hinggan Ling-Mongolian Paleozoic geosynclinal folded belt

宁夏位于中朝准地台和昆仑秦岭地槽褶皱区两大地质构造单元的衔接部位。

Ningxia is situated on the border of two geological structure units which is Sino - Korean paraplatform and Qinling geosyncline folded belt .

另一种意见认为除小的古老地体外，华南不存在古老基底，而是在洋壳基础上发展起来的地槽褶皱区。

The other opinion ( including the authors ' ) regards that the South China does not have old metamorphic basement ( except some small old terranes ), but is a geosynclinal fold region developed on the paleo-oceanic crust .
