引言 证据表明:流体交代作用使陆下岩石圈不同程度地富集了不相容元素,并且,这种富集作用在地幔包体成分和板内大陆上喷发的大部分玄武岩成分中都能体现出来。本文的目的是对在大陆火山弧环境(即活动大陆边缘)中陆下岩石圈在岩浆形成中的卷入程度作出估计。 INTRODUCTION Evidence shows that fluid metasomatism enriches incompatible elements to varying extents in the subterranean lithosphere and that this enrichment can be found in most of the basalt components erupted in the mantle inclusions and in the interior of the plate come out. The purpose of this paper is to estimate the extent of submarine lithospheric intrusion into the magma in the continental volcanic arc environment (ie, the active continental margin).
