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

摘要: 对广东省２个花岗岩赤红壤的微形态研究表明：骨骼颗粒以蚀变石英为主：呈斑晶状分布；土体棱块状结构发育明显，微团聚体轻微发育；细粒物质以其红色、具轻微双折射现象为主要特征；土体中亦可见少量铁锰结核体及粉质体的出现。

Abstract: 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.
