3.
indicate that the deposit origin has close relation with volcanic activity.
通过矿床特征、岩石化学、同位素等分析研究表明,该矿床成因与火山活动关系极其密切,依据矿床成矿特征建立了成矿模式,为该区寻找类似矿床具有一定的指导意义。
5) volcanism
[英]['vɔlkənizəm] [美]['vɑlkənɪzṃ]
火山活动

晚三叠世火山活动对鄂尔多斯盆地长7优质烃源岩发育的影响
2.
The change of volcanic rocks from marine facies to continental facies and change of volcanism from strong to weak indicate that after the Permian the upper mantle materials had long been in a constrictive stage,and that the whole basin sank continuously to receive deposits,thus resulting in crustal thickening.
准噶尔盆地被古生代缝合线构造包围,周缘山系向盆地方向逆冲推覆,显示了盆地处于长期受压的构造环境;火山喷发由海相转变为大陆相,火山活动由强到弱,表明二叠纪以后,上地幔物质一直处于收缩状态,盆地整体持续下沉接受沉积,地壳增厚。

6) volcano activity
火山活动
1.
Through analyses of tectonic geomorphic features in Tengchong region (24°40′～25°30′N,98°15′～98°45′E), it is considered that the local tensile stress environment existing from the Pliocene is an important factor for the volcano activity.
