deep crust meaning in English
地壳深处
Examples
- Ore - forming fluid rooted in the deep crust mixed with meteoric water
成矿流体来源于地壳深部和后期大气降水的加入。 - These studies , therefore , suggest that the songsugou peridotite is not a tectonic massif of the upper mantle but a ultramafic magmatic rock body crystallized in deep crust and tectonically emplaced in the upper crust
从而证明了松树沟橄榄岩体并不是上地幔岩石的残片,而是由岩浆在深部地壳环境下结晶而成并以固态构造侵位于地壳的上部。 - The reason for the moderate and large earthquake of zhengjiang block could be attribute as such features : because of the structure ' s more rigidity and the rising of the several interfaces in the crust , the energy from the deep crust of upper mantle is transported to the middle or upper crust persistently . thus it always accumulates at some locations and this may lead to eart
由于地表火山活动的停止,来自中下地壳和上地慢的大部分能量得不到释放,从而在有利的构造部位积聚,进而在流体的作用下,或在其它外动力诱发下,导致孕震系统失稳而发生地震。 - By physiognomy feature , it could be divided into three types of thermal structure : positive dome model , negative collapse model and border dome core collapse model . based on the depth degree or magma - thermal influenced , it could be divided into five types of thermal structure : ( ancient ) geothermal anomaly focus region model , superficial volcano eruption hydro - thermalism and hypabyssal intrusive model , thermal anticline ( thermal dome ) model , mid - deep intrusive model , deep mantle ( crust ) thermal plume model ; and put forward a perfect model of the thermal structure . there are many interaction system could be induced into a systematic thermal interaction , include : ocean - continent system , basin - mountain interaction , superficial and mid - deep crust - mantle interaction , crust - mantle commingle interaction , vertical thermal interaction ( delamination ) etc .
依据地貌形态分为三类:正向穹窿型、负向塌陷型、边隆核陷型:依据岩浆-热力作用影响的深浅程度或深度分为五类: (古)地热异常群集区、表浅层火山喷发-热液活动与浅成侵入型、热力背斜(热穹窿) 、中深层侵入型、深部地幔(地壳)热柱型;提出了热力构造作用空间分布的理想模式,将洋陆系统、盆山作用、浅表与中深部壳幔作用、壳幔混合、垂向热力作用(拆沉)等纳入一个整体统一的热力作用系统中,为盆地动力学研究打开了一个新窗口;研讨了热力构造研究方法。 - To make the yanshanian volcanic tempral and spatial distribution and evolution law clear , study the relationship of the deep crust - mantle processes and the volcanic rocks , the author selects the typical areas , xishan of beijing , duolun of inner mongolia , west liaoning , as the study areas where the volcanic rocks strata are developed . through the emphasised geological profiles of yanshanian volcanic strata being surveyed , much field work being done detailly , the small volcanic eruptive units have been defined originally , the levels of volcanic activity rhythm being constructed gradually , as a result , a integrated and systemic rhythm of yanshanian volcanic acivity has been constructed
为了揭示该区燕山期火山岩火山活动的时空分布与演化特征,探讨与深部壳幔过程的关系,选择了燕山期火山岩地层发育比典型的北京西山、内蒙多伦、冀北和部分辽西等地区,系统的测制了燕山期火山岩重点地层剖面,通过野外大量的详细观察,从建立最小的火山喷发单元开始,逐步地建立火山活动节律的级别,结合区域地层对比,建立了一个比较完整的燕山期火山活动节律及其级序。
