Some geologists，however，on the basis of observations concerningmantle xenoliths，argue that the mantle is not layered，but thatheterogeneity is created by fluids rich in incompatible elementspercolatingupward and transforming portions of the uppermantle irregularly，according to the vagaries of the fluids pathways.
但是，某些地質學家，以對地幔捕虜岩體所作的觀察爲依據，指出地幔並非是分層排列的，相反，地幔的異質性是由那些富含不相容成分的流質構成的，這些成分趨向於流體而非固體的狀態，自下而上滲透擴散，並依照這些流質流向的'任意性，不規則地將上部地幔的某些部分予以改變。
The very richness and complexity of the meaningful relationshipsthat kept presenting and rearranging themselves on all levels，fromabstract intelligence to profound dreamy feelings， made it difficultfor Proust to set them out coherently.
各種有意義的聯繫在所有的層次上，自抽象的理性至深刻的夢幻般的情感，層出不窮並不斷重新組合排列;正是這些有意義的聯繫的豐富性和複雜性，致使普魯斯特難於將它們錯落有致地安排好。
