THE EFFECTS OF CHEMICAL WEATHERING ON

Abstract: Chemical weathering of Lake Waccamaw limestone neutralizes the acidic swamp waters that drain into the lake and contributes alkalinity and phos phate to the lake water. This limestone contains approximately 0.1% P, which is released as phosphate during chemical weathering. Physical weathering is

Aspects of the biological weathering of Limestone

It is concluded that solution of the limestone to form clints and grikes mainly occurred when there was a covering of glacial drift which is now receding. Solution is still occurring under the drift by a process of weathering which is accomplished by soil-acids of biological origin. The term biological weathering is proposed for the process.
