All the rock material may be discoloredand may be weaker externally than its fresh condition. Less than half of the rock material is decomposed and/or disintergrated to a soil. Fresh or discolored rock Moderate is present either as a continuous framework or as corestones. More than half of the rock material is decomposed and/or disintegrated to a soil. Fresh or discolored rock Severe is present either as a continuous framework or as corestone. All rock material is decomposed and/or disintegrated to soil. The original mass structure is largely intact. Complete Residual Soil All rock material is converted to soil. The mass structure and material fabric are destroyed.

Weathering Fresh Slight

No Visible sign of rock material weathering; slight to no discoloration. Discoloration indicated weathering. All the rock material may be discoloredand may be weaker externally than its fresh condition. Moderate Less than half of the rock material is decomposed and/or disintergrated to a soil. Fresh or discolored rock is present either as a continuous framework or as corestones. Severe More than half of the rock material is decomposed and/or disintegrated to a soil. Fresh or discolored rock is present either as a continuous framework or as corestone. Complete All rock material is decomposed and/or disintegrated to soil. The original mass structure is largely intact. Residual Soil All rock material is converted to soil. The mass structure and material fabric are destroyed. There is a large change in volume, but the soil has not been significantly transported.
