WebHabit/Form: Crystals of calcite have many habits but usually consist of combination of scalenohedrons and rhombohedrons. However, in most rocks, calcite forms anhedral grains or aggregates of grains. Fossil shells and thin veins may be fibrous or columnar. Color: Colorless (often cloudy); can be white, grey, pink.

WebAnhydrite is commonly associated with calcite, halite, and sulfides such as galena, chalcopyrite, molybdenite, and pyrite in vein deposits. Anhydrite is most frequently found in evaporite deposits with gypsum by precipitation of calcium sulfate from evaporation of seawater. Anhydrite can also form through the dehydration of gypsum. http://geologyscience.com/minerals/kyanite/ WebSandstone from the Pennsylvanian-aged Conemaugh Group, WV.

Webthickness. Two thin sections from the cemented level were made two months after the other sections were prepared. Special care was taken to prepare these two sections, because XRD data suggested these samples contained nitratine and/ or halite. These minerals are both highly soluble, so these thin sections were cut using a dry saw (Nesse, 2000).

WebCalcite and Dolomite: Carbonate Minerals. Calcite and dolomite are very similar minerals. Both have the same hardness (H = 3), the same rhombohedral cleavage, and are found in identical geologic settings. The best way to tell one from the other is the acid test: a drop of 1 M HCl on calcite produces an instant, obvious fizz; a drop on dolomite ...

Calcite and halite are two significantly different minerals, although they do share a lot of similar properties. For instance, they both produce white steaks and they are both relatively soft, with calcite only being 0.5 harder than halite.
