What mineral group does tremolite belong to?
amphibole group
Tremolite is a member of the amphibole group of silicate minerals with composition: Ca2(Mg5.0-4.5Fe2+0.0-0.5)Si8O22(OH)2. Tremolite forms by metamorphism of sediments rich in dolomite and quartz. Tremolite forms a series with actinolite and ferro-actinolite.
Is tremolite a chain silicate?
Which view reveals a layered structure showing Si tetrahedral chains (in layers) bonded together by Ca and Mg cations? Tremolite is termed a double chain silicate because pairs of chains of silica tetrahedra linked together extend infinitely in one direction within the crystal.
Is tremolite a rock or mineral?
Tremolite is an important rock-forming mineral and occurs most commonly as a white to light green, granular to fibrous component of metamorphosed carbonate rocks, especially skarns and dolomite marbles, where the crystals and aggregates can become quite large.
How do you identify tremolite?

Is hornblende a tremolite?
Minerals actinolite–tremolite series are not stable and can easily alter in the chlorites, tremolite, and talc on the Earth’s surface. The hornblende group includes amphibole rich in trivalent iron and aluminum.
Where are tremolite found?
Where is Tremolite Found? Outside of the United States, tremolite was primarily mined in South Africa and India. In South Africa, it was extensively mined in the beginning of the 20th century, but it became secondary to the mining of amosite and crocidolite.
Is serpentine toxic?
Serpentine is not a toxic rock. It sometimes contains the fibrous mineral chrysotile asbestos, but chrysotile asbestos is not the form of asbestos that is proven to cause mesothelioma and lung cancer.
Is gold found in serpentine?
Gold. Veins of gold-bearing quartz are not commonly found in serpentine, but gold veins are often in close association with serpentine.
