CRYSTAL SPECIMEN

SIZE 100 X 80 X 55 MM

ON WOODEN STAND CUT TO SHAPE

CRYSTALS masses have consolidated from aqueous solution or from molten magma. The vast majority of igneous rocks belong to this group and the degree of crystallization depeds primarily on the conditions under which they solidified.

 

Such rocks as granite, which have cooled very slowly and under great pressures, have completely crystallized, but many lavas were poured out at the surface and cooled very rapidly; in this latter group a small amount of amorphous or glassy matter is frequent.

 

Other crystalline rocks, the evaporites such as rock salt, gypsum and some limestones have been deposited from aqueous solution, mostly owing to evaporation in arid climates. Still another group, the metamorphic rocks which includes the marbles, mica-schists and quartzites; are recrystallized, that is to say, they were at first fragmental rocks, like limestone, shale and sandstone and have never been in a molten condition nor entirely in solution.

 

The high temperature and pressure conditions of metamorphism  have acted on them erasing their original structures, and inducing recrystallization in the solid state.
