UltraCarb is a multifunctional hybrid of two minerals from a natural deposit: hydromagnesite (hydrated magnesium carbonate) and huntite (magnesium calcium carbonate).
In some instances, the images had been executed over a white background created by huntite being applied to the rock or some underlying paintings (Clarke, 1976).
2]O; eleven huntite samples, nine of which also contained calcite CaC[O.
Objective: The concept of the present project WOOD-FLARETCOAT is to solve the problem of producing improved flame retardant coatings for wood products, through the development of non-halogenated flame retardant systems based on inorganic flame retardant nanofillers (nano magnesium hydroxide, huntite and hydromagnesite) functionalised with ROs and incorporated into several water born polymeric matrix, to constitute composites.
Depending on the intended industrial mineral use, natural brucite competes for its share of the market with synthetic brucite, commonly referred to in the manufacturing industry by its chemical formula, magnesium hydroxide, and with other minerals and compounds such as magnesite, dolomite, huntite, hydromagnesite, MgO, CaO, zeolites and others.

Small amounts of gypsum associated with huntite have been identified in the silica-carbonate rock of the Clear Creek mine.
A mixture of huntite and hydromagnesite, Ultracarb imparts a flame retardant action when mixed into polymers by means of the evolution of carbon dioxide and water at temperatures above 225 [degrees] C.

Therefore it can be concluded that the MgO existing in the Magnesites and Huntites in the mentioned Ophiolitic regions and other Ophiolitic areas have been originated from ultramafic rocks.
