Origin of natural stones
Export quarries in India are roughly concentrated in two regions:
- North India: states of Rajasthan, Madhya Pradesh, Uttar Pradesh
- South India: states of Andhra Pradesh, Karnataka and Tamil Nadu
Nationwide, there are about 100 provenances, in which natural stones are mined for export. These are small-scale areas (such as a mountain) in which the same type of stone is mined. This can be done by several tenants or owners. A provenance can be divided into up to 12 mining sections.
Export quarries in China are also roughly concentrated in two regions:
- Southern China, especially the federal state of Fujian; Fujian granite is classified by the G600 number (e.g., G602)
- North China, especially the state of Shandong; Shandong granite is classified by the G300 number (e.g., G341)
Use of natural stones
Granites have great economic importance in the construction industry because of their high resistance, hardness and weather resistance and because of their good sandability and polishability. You can find them:
- as gravestones in cemeteries
- in road construction as paving stone, curb, gravel, (mostly from China)
- in railway construction as gravel
- in building construction as exterior wall cladding, flooring
- in interior design as wall cladding, stair cover, interior trim, table and kitchen top
- in horticulture as paving stone, rebate stone, well.
Marble is a younger, softer rock than granite and is used as:
-
- Flooring
- wall panels
- steps
etc. – increasingly as well
- gravestones.
Sandstone has been widely used since ancient times as
- building blocks,
- work stone
- decoration stones
The softer clay-bound sandstones are often used for sculpting. The rather harder quartz-bound species are particularly suitable for
- Floor coverings and
- steps.
