5 Formation

5.1 Formation

Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

All about Aplite and Amphibolite Properties

Know all about Aplite and Amphibolite properties here. All properties of rocks are important as they define the type of rock and its application. Aplite belongs to Igneous Rocks while Amphibolite belongs to Metamorphic Rocks.Texture of Aplite is Granular, Graphic whereas that of Amphibolite is Banded, Foliated, Massive. Aplite appears Veined or Pebbled and Amphibolite appears Foliated. The luster of Aplite is dull to pearly to subvitreous while that of Amphibolite is vitreous to dull. Aplite is available in black, grey, orange, pink, white colors whereas Amphibolite is available in black, brown, green, grey colors. The commercial uses of Aplite are curling, gemstone, laboratory bench tops, small sculptures, tombstones and that of Amphibolite are cemetery markers, commemorative tablets, creating artwork.
