Geology
Geological setting:
Ferrar Dolerite intrudes the granite basement as narrow sills and dykes and commonly outcrops on ridges
Patterned ground:
Nil observed
Surface weathering or surface features:
Dolerite bedrock has fractured to form a bouldery (felsenmeer) surface; a thin fine gravelly exfoliate layer forms the soil surface; a small amount of fine material is present in cracks between boulders; soil colour varies with redder hues under some boulders
