The fluid-absent melting experiments of amphibolite do not support the assumption that, the intermediate "C-type" adakite (with SiO2 contents of 56 ~ 67 %) is originated from the melting of basaltic source-rock.
目前的实验岩石学结果不支持玄武质源岩部分熔融形成SiO2含量中等(56 ~ 67 %)的"C型埃达克岩"的假设。

On the basis of an integrated analysis of the geochemical features of these volcanic rock associations,this paper concludes that thebasalts originated mainly from interaction between mantle-derived magma and low-crustal materials, and rhyolitic volcanic rocks resulted from thermal and chemical interaction between basaltic magma and the upper part of crustal materials.Basalts and rhyolites in different cycles have different source regions,and they are products of multiperiodic pulsive layer partial melting.
根据对火山岩地球化学特征的综合分析表明,玄武岩主要为幔源岩浆与下部地壳岩石相互作用的产物,而流纹岩则为玄武岩浆与上部地壳物质进行热及成分交换的结果,不同旋回的玄武岩和流纹岩有不同的源区,为多次脉动分层部分熔融的产物。

Recent studies of abyssal peridotites show that they are not melt residues of batching or fractional melting of pyrolite directly after melt extraction of MORB. Petrological studies of peridotites from Luobusa ophiolite massif also indicate that the mantle peridotites are not simple residues of primary pyrolite either.
罗布落蛇绿岩橄的镜下观察和岩石化学资料也证明,它不是原始地幔岩经局部熔化后的残余物,而且由来自更深层的地幔过渡带的硅酸盐超高压矿物底辟上升经熔取出玄武质熔体后,再次局部熔化后的残余物。

Rock types include basalt,trachybasalt, alkaline basalt, andesite and andesibasalt, which belong to alkalinity-weak alkalinity rock series, and give priority to neutrality-basic volcanicrock, that indicate the tectonic setting of continental rift.
岩石类型为玄武岩、粗面玄武岩、碱性玄武岩、安山岩和玄武安山岩,属于碱性-弱碱性岩系,以中性-基性火山岩为主,指示出大陆裂谷型构造背景。
-
The petrological study and studies in element and isotopic geochemistry indicate that the pluton belongs to high-potassium calc-alkaline I-type granite, whose magma came from basic basalt in the thicken crust bottom by partial melting, and are of syn-collisional features. The pluton provides a direct petrological evidence of the plate collision and amalgalation.
岩石学、元素和同位素地球化学研究表明,岩体属于高钾钙碱性Ⅰ型花岗岩,岩浆来源于加厚地壳底部基性玄武质岩石的部分熔融作用,属同碰撞型花岗岩,是板块碰撞拼合的直接岩浆岩证据。
