在许多斑岩铜矿矿床中，地表风化使得金属铜进一步富集。

In many porphyry copper deposits, additional enrichment of the metal has been caused by surficial weathering.

但由于构造活动及地表风化作用的影响，矿层在地下水的作用下，其保存情况及矿石类型形成了明显的分带性。

But due to the influence of the structural activities and weathering in the surface, under the action of underground water, the ore types and the preservation of ore seam showed obvious zoning.

然而，他补充道，还需要在确定金星地表如何重塑这个问题做出更多的努力，科学家需要确切地了解地表风化率如何影响辐射率。

He added, however, that in order to make even more progress in determining how Venus resurfaces, scientists need to learn exactly how weathering surface rates affect emissivity.
