This solid Sandstone core with quartz veins, is moderately strong and found near Betong area, about 13m below ground level. The veins appears to be parallel to each other, dipping at an angle.
Near to the top, vein directions can be opposite, perhaps chaotic. Deterioration seems to occur near to these veins and therefore above this rock core, 12m to 13m depth, the core breaks in many small flat pieces.
