Mineralogical Characteristics And The Pedogenetic Processes Of Soils On Coral Reefs In Ambon

Soils developed on coral reef parent materials in Hitu and Wailiha, Ambon were investigated their mineralogical characteristics regarding to the relationship to pedogenesis. The analyses concerned with the characteristics of soil chemical, physical and mineralogical of the rock fragment and sand, silt and clay fractions to investigate the pedogenesis processes. Both profiles indicated the clayey texture, the slightly neutral reaction, the high cation exchange capacity, base saturation and iron oxide. The mineralogy analyses of rock fragments and sand fractions indicate that besides carbonate minerals also found silicate minerals. The clay mineralogy indicate the domination of kaolinite, gibbsite, and goethite, the reflection of soil wi th intensely weathered. Pedogenesis process shows the clay translocation, indicate that the weathering process occur under the tropical influences.
