SLATE STONE DESCRIPTION

Slates are dense and fine grained rock. The colour of slates are generally gray, red, brown and green ranging from dark to light. It is produced by the compression of clays, shale, and various other rocks developing a characteristic cleavage consisting SERICITE quartz with BIOTITE, chlorite, and hematite as principal accessories.

In other words slates are generally formed by low-grade regional metamorphism of pelithic sediments or fine-grained tuffs. It can be associated with other metamorphic sedimentary or volcanic rocks.

Slates are or argillaceous of metamorphic rocks and can also be defined as a layered stone. Fossils may be sometimes preserved in slate but are invariably distorted. Folds are often apparent in the field. Too fine-grained are tough to distinguished with the naked eye.

Physical Properties of Slate :
Physically these are Metamorphic-argillaceous rocks, which has developed a well-marked splittable cleavages with or without developed recrystallization & spots/knots of minerals like garnet, pyrite, andulasite, etc. They are normally fine to medium grained, moderately hard & compact, less homogeneous with varying textures & shades. It has an ability to split into thin layers along the plane of cleavages due to flattened & elongated minerals along the plane of cleavage.

Specific Gravity - 2.65 to 2.80
Porosity - Low to very low
Water Absorption - 1.5 to 2%
Weather Impact - Resistant corrodibility - 0.4 to 0.7%

Chemical Properties of Slate :
Chemically they are Multi-Mineral, metamorphic,argilaceous made of an aggregate of minerals and colloidal substances. Essentially mineral composition includes quartz, mica,chlorite,sericite & oxides of iron with occasional spots/knots of minerals like garnet, pyrite, andulasite etc.

Available sizes : 30x30, 20x30, 20x40,30x60, 40x40, 60x60cm
Thickness : 10mm to 25mm.
Available in tumbles, mosaics, ledge and in flag stones also.
