Microcrystalline metamorphic rock most commonly dervived from shale and composed mostly of micas, chlorite and quartz. The micaceous minerals have a subparallel orientation and thus impart strong cleavage to the rock which allows the latter to split into thin but tough sheets.
Highly indurated, typically metamorphosed sandstone containing at least 95% silica which fractures conchoidally through grain.
Sedimentary Rock composed mostly of mineral and rock framents within the sand size range 2 to 0.06 mm and having a minimumof 60% free silica, cemented or bonded to greater or lesser degree by various materials include silica, iron oxides, carbonated or clay.
Serpentine Marble, a rock consisting mostly or entirely of serpentine (hydrated magesium silicate), commomly veined with calcite, and dolomite or magnesite or magnesium carbonate
