These deposits develop from the mechanical and chemical breakdown of high temperature igneous rocks known as ultramafic rocks. These deposits consist of a predictable weathering profile that includes five “zones”: The un-weathered ultramafic bedrock, the weathered bedrock or “saprolite”, a clay-rich layer, limonite zon在geologyforinvestors上查看更多信息
