Talc Mineral | Physical - Optical Properties, …
Dense, high-purity talc is called steatite. It is a metamorphic mineral found in veins and magnesium-rich rocks. It is often associated with serpentine, tremolite and forsterite and occurs as an alteration product of silica-poor igneous rocks. Talc is widespread and is found in most areas of the world where low-grade metamorphism occurs. The name soapstone is given to compact masses of talc and other minerals …

Talc Mineral Production - Formation of Talc | …
Talc is basically a mineral which belongs to the class of silicates. The formation of talc is achieved when the carbonate sediments undergo through contact metamorphosis . It is also formed when the magmatic rocks which are rich in magnesium undergoes the hydrothermal alteration .
Talc - an overview | ScienceDirect Topics
Talc is a metamorphic mineral resulting from the metamorphism of magnesium minerals such as serpentine, pyroxene, amphibole, olivine, in the presence of carbon dioxide and water. The main uses of talc are in the manufacture of powder, the production of soap and paper, and as a refractory material. Pyrophyllite (Al 2 (OH) 2 Si 4 O 10) crystallizes in monoclinic system and occurs as crystalline ...
Talc carbonate - Wikipedia
Talc carbonates are a suite of rock and mineral compositions found in metamorphosed ultramafic rocks. The term refers to the two most common end-member minerals found within ultramafic rocks which have undergone talc-carbonation or carbonation reactions: talc and the carbonate mineral magnesite. Talc carbonate mineral assemblages are controlled by temperature and pressure of metamorphism and …
Mineral alteration - Wikipedia
Mineral alteration refers to the various natural processes that alter a minerals stone composition or crystallography.. Mineral alteration is essentially governed by the laws of thermodynamics related to energy conservation, relevant to environmental conditions, often in presence of catalysts, the most common and influential being water (H 2 O).

Talc - Sandatlas
Talc is a hydrothermal mineral formed often at the expense of serpentine which is also an alteration product of olivine and pyroxenes (common components of ultramafic rocks). Talc may form as dolomite metamorphoses, but in this case the dolomite needs to be impure. Otherwise, the lack of silica will be limiting the growth of talc. It also seems to be a mineral that easily gets pushed aside by other …
ALEX STREKEISEN-Talc-
• Alteration of magnesium-rich ultramafic rocks These talc deposits result from hydrothermal alteration of magnesium-rich ultramafic rocks. Alteration process is two-fold: first hydration of these mafic minerals such as olivine or pyroxene by H 2 O influx into serpentine which is a hydrated Magnesium-silicate. Second step is alteration of serpentine into talc and magnesite by CO 2 - addition:
Talc Facts - BMM
Talc is an alteration mineral. It is formed by geological modification of some host rock. Most talc is formed from the alteration of magnesite (MgO) in the presence of excess dissolved silica (SiO2). Altering serpentine or quartzite can also form talc. The different alteration routes form talcs that have significant differences in chemistry, color, morphology and impurities.

15.06.2015 · The alteration zones are represented by rocks in which the mineral assemblage of the partly altered peridotites (olivine, clinopyroxene, serpentine, brucite and spinel-group minerals) has been altered to serpentine, carbonate and talc. The vertical thickness of the alteration zones is commonly in the range of 1 to 5 m, but reaches up to 12 m. The alteration has created sharp reaction fronts ...
Alteration (Geologie) – Wikipedia
Als Alteration (von lateinisch alterare für „umstellen, verändern“) bezeichnet man in der Geologie, Lagerstättenkunde und Mineralogie die mineralogischen und chemischen Veränderungen eines Erzkörpers und/oder seines Nebengesteins, wobei die Minerale in einem Gestein in Sekundärminerale umgewandelt werden.
