Definition and Composition: Calcite is a carbonate mineral, which means it contains the carbonate ion (CO3^2-) as a fundamental building block. It is one of the most common minerals on Earth and can be found in various geological settings. Its name is derived from the Latin word "calx," which means lime, highlighting its close association …

University of Minnesota's Mineral Pages: Calcite. Onyx is a term used for both a layered variety of quartz, as well as a layered variety of calcite, so don't be confused by the term's double use. The layered calcite (often known as Mexican Onyx) can be distinguished because it is softer and is easily carved into different shapes.

The white areas represent unconformities. The three main portions of bedrock geologic time in Minnesota are labeled in red: Precambrian, Paleozoic, and Mesozoic (modified from Southwick and Lusardi, 1997, fig. 5). The bedrock geology of Minnesota can be subdivided into three general categories based on geologic time.

University of Minnesota''''s Mineral Pages: Dolomite In sedimentary dolostones, dolomite is most often associated with calcite, aragonite, gypsum, anhydrite, chert, and halite. Vein deposits of dolomite occur with quartz and other common vein minerals, such as calcite, magnesite, fluorite, siderite, and sphalerite, or with metallic ore minerals ...

Calcite: Mineral information, data and localities. Calcite-Rhodochrosite Series. A very common and widespread mineral with highly variable forms and colours. Calcite is best recognized by its relatively low Mohs hardness (3) and its high reactivity with even weak acids, such as vinegar, plus its prominent rhombohedral cleavage in most varieties.

Magnetite By: Mireya Santos, Noemi Garcia, and Kylie Dunn

Mineral name: Magnetite: Chemical Composition: Fe2+Fe3+2O4. Color: Black. Streak: Black. Hardness: 6. Cleavage: There is no cleavage. Magnetite may show some parting, which is a break along structural …

Cleavage is described by the number of different direc tions or planes along which the mineral splits. As illustrated on page 6, mica has a single cleavage plane; feldspar splits …

University of Minnesota's Mineral Pages: Calcite. Calcite: Calcite is also transparent and translucent like halite, but its cleavage is rhombohedreal rather than cubic. Calcite also reacts easily with dilute acid, and lacks halite's salty taste. Do not test the sample's taste after testing it with dilute acid however. WhatsApp

Chalcopyrite is a fascinating rock that can be found all over the world, even in Minnesota. It comprises copper, iron, and sulfur, which is what the name "copper iron sulfide mineral" means. This mineral is easy to find because it is a unique golden-yellow color that makes it look like gold.
