University of Minnesota’s Mineral Pages: Calcite

In these rocks, calcite is often the only mineral present, but in some sedimentary environments, calcite may be associated with dolomite, gypsum, anhydrite, chert, or halite. In hydrothermal veins, quartz and other common vein minerals such as pyrite, dolomite, fluorite, galena, and chalcopyrite may occur with calcite.

Calcite Origin and occurrence Britannica

Calcite also occurs widely in veins: some of the veins are wholly or largely calcite; others contain valuable ore minerals and are usually described as ore veins, even though calcite is the predominant constituent. The sedimentary rocks composed largely of calcite include limestones of chemical and biochemical origin

Calcite mineral Britannica

A large percentage of the calcite, the most abundant of these carbonate minerals, occurs in limestones, which constitute noteworthy proportions of many sequences of marine sediments. Calcite is also the chief component of marls, travertines, calcite veins, most speleothems (cave deposits), many marbles and carbonatites, and some ore-bearing veins.

VEIN DEPOSITS Earth Science

A great many valuable ore minerals, such as native gold or silver or metal sulphides, are deposited along with gangue minerals, mainly quartz and/or calcite, in a vein structure. A vein system is a group of discrete veins with similar characteristics and usually related to the same structure.

geology How does quartz form in calcite veins? Earth

There is also the matter of reaction kinetics, such that some minerals may be over-saturated but so sluggish to precipitate that you won't find it in the vein. Calcite and quartz are both common, almost ubiquitous in limestone veins. Obviously, the calcite is re-precipitated limestone.

Dec 01, 2018· Of these, calcite veins were the most commonly reported (110 localities), and the host rocks were mainly muddy hydrocarbon source rocks. “Fibrous veins” usually refers to any vein with distinctly elongate crystal morphologies with extreme length-width ratios, and typically the fibres are oriented approximately perpendicular to the vein walls.

Calcite Mineral Uses and Properties

Calcite is a rock-forming mineral with a chemical formula of CaCO 3. It is extremely common and found throughout the world in sedimentary,metamorphic,and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" one that is found everywhere.

University of Minnesota’s Mineral Pages: Dolomite

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 such as galena, pyrite and chalcopyrite. Although uncommon, when dolomite occurs in altered ultramafic igneous rocks, it may be associated with magnesite, serpentine, and talc.

Introduction: calcite occurs in a great diversity of parageneses and geological settings. It is an important rock-forming mineral (e.g. as the major constituent of limestone); it is a widespread product of low to medium-grade metamorphism and hydrothermal alteration in many rock-types and it is a common hydrothermal vein-mineral.
