Release of iron oxide in red‐brown soil formation from the weathering of limestone. 1.—Effect of carbonic acid
Abstract In carbonic acid leaching under laboratory conditions, which were considered to be almost identical with rainwater leaching of limestone rocks, it is shown that there is a gradual release of Fe (and Si, Al, Ti, etc.) along with the bulk removal of the alkaline earth carbonates. The resultan...

Summary: | Abstract In carbonic acid leaching under laboratory conditions, which were considered to be almost identical with rainwater leaching of limestone rocks, it is shown that there is a gradual release of Fe (and Si, Al, Ti, etc.) along with the bulk removal of the alkaline earth carbonates. The resultant product is a reddish‐brown to greyish‐brown residue, and perhaps represents an intermediate stage between the initial rock and the final red‐brown soil. A similar observation may also be made from the acetate‐buffer leaching of limestone rocks. |
