Abstract

Chemical weathering of rocks including anorthosite is studied experimentally. Photographic expression of anorthosite is then outlined and statistical studies of slopes and grain size of products of weathering are made. Then tone of aerial photographs and color photography are considered. It is concluded that anorthosite should weather faster in areas where vegetation is present, and that the geomorphic expression of anorthosite is mainly related to jointing; in other aspects of surface expression, anorthosite is not different from other rock types.
