In the formation of schist, the temperature has been hot enough so that individual mica crystals are visible, and other mineral crystals, such as quartz, feldspar, or garnet may also be visible. In gneiss, the minerals may have separated into

CLASSIFICATION OF ROCKS AND DESCRIPTION OF PHYSICAL PROPERTIES OF ROCK Introduction Uniformity of definitions, descriptors, and identification of rock units is important to maintain continuity in geologic logs, drawings, and reports from a project with multiple drilling sessions, different loggers and mappers. physical classification of rocks ppt Sediment types. Clastic sediments are derived from the physical deposition of particles produced by weathering and erosion of preexisting rock. Chemical and

Rock types and classification 3 Mibei Texture. When magma cools slowly large crystals form and rock forms phaneritic texture on the other hand if magma cools fast then small crystals form sometime a glassy texture where no minerals form can be achieved this way. physical classification of rocks ppt
