题目

英语翻译
a model is proposed whereby mixing between partial melts derived from these geochemically enriched silicate veins,and an incipient to low percentage melt from the surrounding geochemically depleted suboceanic asthenosphere occurs as a consequence of increasing degree of melting with adiabatic upwelling.

答案

a model is proposed这是主句.
剩下都是by whereby引导的,意思就是按照/根据proposed model
whereby里面,句子结构是mixing between .melts and melt ... occurs ...,发生混合.
为什么发生混合呢,as a consequence of,因为
提出（提议）了一个模型,根据这个模型,由于随着绝热上涌（upwell）熔融程度增加,这导致地球化学方式富集的硅酸盐矿脉产生的部分熔化物（melts）,与地球化学方式贫化（deplete）的海底软流圈（asthenosphere）产生的早期到少量（low percentage）熔化物（melt）,发生混合.
incipient to low percentage,也可能意思是早期少量；adiabatic upwelling：也许是绝热（层）上涌.术语可能不够专业,供参考.
