Calcite: The mineral Calcite spar information and
Calcite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another They are similar in many physical properties, and may partially or fully replace one another, forming a solid Directed stress can cause new minerals to form within a rock, but much more commonly it produces deformation, fracturing, or textural changes only Mineral grains may rotate, align, become distorted, or disintegrate Figure 820 shows 8 Metamorphic Minerals and Metamorphic Rocks – Calcite is one of the most common and widespread minerals It is a principal component of most sedimentary carbonate rocks (limestone, chalk, travertine, etc) but occurs in metamorphic (marble, hydrothermal veins) and igneous Calcite SandatlasThermal contact metamorphic rock type of mudstone is spotted slate, knotty slate, and hornstone; carbonate rock will develop into marble after thermal contact metamorphism; clastic rock is not easily changed—under thermal contact metamorphism, if the metamorphism is shallow, the sandy texture still maintains and forms metamorphic sandstone; and igneous rock is generally the Contact Metamorphism: Causes, Examples, Occurrence

Deformation, Metamorphism, and Mineralization in GypsumAnhydrite Cap Rock
However, much of the rimgypsified rock seems to have been exceptionally porous, and possibly the rim gypsum and its associated phenomena are due to this porosity rather than to localized external factors In many parts of the cap rock gypsum has reverted to anhydrite, here called “regenerated anhydrite”2019年5月10日 Andrew Alden Amphibolite is a rock composed mostly of amphibole mineralsUsually, it's a hornblende schist like this as hornblende is the commonest amphibole Amphibolite forms when basaltic rock is subjected to higher temperatures between 550 C and 750 C) and slightly greater pressure range than that which yields greenschistMetamorphic Rock Types: Pictures and Descriptions ThoughtCo2023年1月28日 On the other hand, country rocks that experienced medium or hightemperature regional metamorphism prior to the intrusion show limited effects of contact metamorphic overprinting because the older mineral assemblages persist at contact metamorphic conditions Contact metamorphic rocks are generally finegrained and lack schistosityIntroduction to Metamorphic Rocks, Rock Metamorphism, and Metamorphic An evaporating body of water will usually precipitate calcite first, followed by rock gypsum, and then rock salt Rock gypsum does not react to dilute hydrochloric acid, unlike the mineral calcite, and its crystals are usually prismatic or rhombshaped, unlike rock salt Rock gypsum is softer than both calcite and halite and, therefore, more Sedimentary Rocks – Introduction to Historical Geology
