TYPES OF DIMENSION STONE:
@ecgeology
The commercial dimension stones are familiar by the names granite, marble, slate,
sandstone and limestone. However, in commercial parlance, each of these commodities signify a group of petrologically distinct rocks as below.
1. Granite:
It includes (in addition to true granite) diorite, basalt, dolerite, gabbro,
anorthosite, pyroxenite, charnockite, porphyry, rhyolite, leptynite, andesite, syenite, gneiss, schist, diabase, felsite, monzonite and khondalite.
2. Marble:
It includes (besides true marble) calcite marble, dolomite marble,
magnesium marble, onyx marble, massive serpentine (mined as Verde Antique in
Vermont, USA and as green marble in Rajasthan, India) and travertine marble.
3. Sandstone:
It includes both sandstone and quartzite (including the green coloured fuchsite quartzite).
@ecgeology
4. Limestone:
To distinguish this splittable limestone from the massive limestone commonly used for cement manufacture, etc., it is generally referred to in industrial parlance as flaggy limestone or simply flagstone. It usually signifies the argillaceous, siliceous and dolomitic varieties of limestone which are hard. Its most well known Indian example is Kota stone.
@ecgeology
5. Slate:
It includes both slate and phyllite.
Much depends on amenability to cutting and polishing and certain basic characteristics of the rock, innovative ideas of the producer and his salesmanship. And it is possible that with time, more and more unconventional types of rock may be exploited for manufacturing
dimension stones. The list given here is by no means exhaustive.
All these varied types of rock are grouped under one economic commodity namely,
dimension stone, because there are certain common physical and economic criteria
transcending the chemical and mineralogical definitions that impart some seemingly distinct petrological identity to each of them.
