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，以對地函捕虜岩體所作的觀察為依據，指出地函並非是分層排列的，相反，地函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，不規則地將上部地函的某些部分予以改變。
