Stone Catalog


Slate

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.

Quartzite

Highly indurated, typically metamorphosed sandstone containing at least 95% silica which fractures conchoidally through grain.

Sandstone

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.

Green Marble

Serpentine Marble, a rock consisting mostly or entirely of serpentine (hydrated magesium silicate), commomly veined with calcite, and dolomite or magnesite or magnesium carbonate

Travetine Marble

A Porous or Cellularly layer, partly crystallin calcite of chemical origin.

Onyx

Translucent, generally layered, cryptocrystalline calcite with colour in pastel shades, particularly yellow, brown and green.

Limestone

a rock of sedimentary origin composed principally of calcium carbonate( the mineral calcite), or the double carbonate of calcium and magnesium( the mineral dolomite) or some combination of these 2 minerals.

Marble

Carbonate rock that has acquired a distinctive crystalline texture by recrystallization , mostly by heat and pressure during metamorphism and is composed principally of carbonate mineral calcite and dolomite, singly or in combination.

Granite

A visibly granular, igneous rock, consisting mostly of quarts and feldspars. the texture is typically homogenous but may be gneissic or porphyrite.
