Chemical and mineralogical studies indicate that the weathering took place in a humid, warm or hot climate and that laterization was the dominant process.The results of pre-Fountain and recent weathering are compared and contrasted.The red color of the Fountain formation is regarded as inherited from a deeply weathered extensive red-stained pre-Fountain regolith.
