Thus, snowflakes form euhedral, six-sided rocks, the presence of euhedral crystals may signify that they formed early in the crystallization of magma or perhaps crystallized in a cavity or vug, without hindrance from other crystals.

"' Euhedral "'crystals are those that are well-formed, with sharp, easily recognised texture is composed of mineral grains that have no well-formed crystal faces or cross-section shape in thin section.

The Kaminak supracrustal belt preserves igneous textures including interlocking quartz and plagioclase that are intergrown with platy biotite ( 2.084-1.914 Ga ) and stubby euhedral grains of veins of green biotite that are interpreted to have been emplaced there by a hydrothermal event accompanying a deformation along this contact area.

This breccia is a Carbonate altered, with minor content kaolinite altered clasts, localized fluorite matrix, polymicitic carbonate altered shale and carbonate vein clasts, laminated to massive euhedral to anhedral carbonate matrix, chaotic order, clast-supported to matrix-support, fine to very coarse unsorted sharp clast contacts, sub-angular to angular.
