Development of bauxite in relation to parent material near Jarrahdale, Western Australia

Abstract
The relationship between well‐exposed bedrock materials and lateritic bauxite developed over them was investigated in a deep railway cutting, located within the Jarrahdale bauxite mining area in southwestern Australia. Observations in the field and chemical and quantitative mineralogical analysis indicate that the bauxite developed by lateritization in place of the underlying gneissic‐granite/meta‐quartz dolerite basement complex in a leaching environment.
