STUDIES ON THE MICROMORPHOLOGICAL CHARACTERISTICS OF LATERITIC RED SOILS ORIGINATING FROM GRANITE IN GUANGDONG

Studies on the micromorphological characteristics of two soils originating from granite in Guangdong province indicated:the skeleton of the soils were mainly eroded quartz and they appeared in the porphyric pattern. A well-developed prismatic structure and slight microaggregation were found in the soil body, the plasmas were in red and showed slight birefringence. Some concretions of Fe, Mn and siltane were also found in the soils body.
