地台活化

同位素体系计时结果表明地幔交代作用是导致地台活化的先驱事件。

The timing result of isotopic systematies reveals that mantle metasomatism was a precursory event resulting in platform activation .

坝区花岗岩体形成于地槽期，强烈改造于地台活化期。

The granite in dam site was formed in the period of the geosyncline and strongly reformed in the period of platform activation .

地台活化主要表现为燕山&喜山期构造和岩浆活动对原有地质构造和金矿化进行了强烈的改造。

The main activity of platform are that the original geological structure and Au were reformed intensely by Yanshan-Xishan period structure and magmatic activity .

它既是华北地台活化的重要深部地质作用，亦是深部去根作用的具体体现。

It is not only an important deep geological process of North China platform activation but also the concret embodiment of deep " de-rooting " .

中、新生代的地台活化期，长期受劳亚陆块、羌塘昌都陆块和扬子陆块不均匀的联合作用，构造热液活动复杂。

During the period of platform activation in Mesozoic era and Cenozoic era , the tectonic - hydrothermal activity is complex because of the uneven action of Laurasia long-term land mass , the Qiangtang-Qamdo land mass and Yangtze land mass .

The crustal evolution in Liaoning Province has undergone multiple stages , in which the basement was formed in Archeozoic - Paleoproterozoic Era , platform cover was developed in Mesoproterozoic-Middle Triassic , and platform was mobiled of after Middle Triassic . The Nos.

辽宁省位于华北地台北缘，其地质构造演化主要经历了地台基底形成（Ar－Pt1）、盖层沉积（Pt2－T2）、地台活化（T3以后）三个阶段。

Liaoning province is located on the northern borderland of North China Platform , which has mainly experienced three stages : the forming of platform basement ( Ar-Pt 1 ), the depositing of cover ( Pt 2-T 2 ), and the activizing of platform ( after T 3 ) .
