Products containing basalt have no toxic reaction with air or water. They are also non-combustible and will not explode when subjected to fire.
Basalts are as common as the formation of the Ocean floor. Basaltic rocks are ferromagnessian rocks and intrusive igneous rocks. This implies they are formed within the Earth's crust, and they make up the ocean floor. They are dark and dense rocks and occurs in large scale as M.O.R.B. (Mid-oceanic Ridge Basalt).
Basalt is an extrusive volcanic rock formed from the decompression melting of Earth’s mantle. It is expelled through volcanic eruption and it produced grey to black and fine grained rock. It may contain minerals and elements. Basalt is also formed in other planets and asteroids.Look here for more information:http://geology.com/rocks/basalt.shtml

I think it might be Crystal?
ferromagnesian rocks are dark coloured rocks with high melting point and high specific gravity. they are basic rocks that consists of the elements like iron and magnessium, and are made up of mostly the olivine and pyroxene minerals. ferromagnesian rocks are formed from the earths interior espesially within the mantle. they include gabbro, basalt and peridotite.
chota nagpur is a store house for minerals as its soil contain many minerals within it.
Ossification
A number of different minerals can be found within geodes, but they are mostly composed of quartz.
Minerals
Two examples that come to my mind right away are Basalt and Obsidian. You can tell on your own if a rock has cooled quickly by whether or not you can see individual grains of minerals within the rock. So if you cant see any, then its most likely that the rock cooled quickly.

Several minerals are left behind when water evaporates.
The special and role and place of organism within in its habitat is its niche.

Those of the minerals forming the rock.
Basalt is a fine grained VOLCANIC igneous rock of mafic composition typically made up of the minerals olivine, clino-pyroxene and calcium rich plagioclase. It is the product of undifferentiated magma at either constructive or destructive plate margins. Granite is a coarse grained PLUTONIC igneous rock of felsic composition typically made up of the minerals quartz, orthoclase, sodium rich plagioclase and either biotite or muscovite mica. It is the product of a highly differentiated, partial melting in which the felsic components have become a segregated fraction separate from the main subducting plate within a destructive plate margin. The two rocks are very different in colour; basalt is grey-brown whilst granite is pink or pale grey. They are however, both igneous rocks & may be used for construction. Granite is frequently used as the building blocks for houses, basalt is more commonly used for kerb stones.
