WebA rock consists of 10% euhedral phenocrysts of Anorthite, 20% as a mix of subhedral crystals of An and Fo with proportions of 70% An and 30% Fo, and a groundmass of anhedral crystals that make up 70% of the rock. The groundmass consists of 50% Di, 43% An, and 7% Fo. Plot the original magma composition as Xb, Webeuhedral (idiomorphic) A morphological term referring to grains in igneous rocks which have a regular crystallographic shape. Euhedral forms are developed when a crystal grows freely in a melt and is uninhibited by the presence of any surrounding crystals.
Recognizing the habit can aid in mineral identification and description, as the crystal habit is an external representation of the internal ordered atomic arrangement. Most natural crystals, however, do not display ideal habits and are commonly malformed. Hence, it is also important to describe the quality of the shape of a mineral specimen: • Euhedral: a crystal that is completely bounded by its characteristic faces, well-formed. Synony…
