49 – 3.57 Chemistry: Al2SiO4(F,OH)2. Fracture is splintery. Specific Gravity: 3.21 (Calculated) Crystal System: Monoclinic. Deriving its name from a locality in the Swiss Alps, tremolite is a member of the amphibole group, a complex series of silicate minerals. Since nonasbestiform and asbestiform varieties of the last three minerals have the same name, new legislation was needed to specifically exclude the nonasbestiform varieties of these minerals. Silicate Zircon. 2. The hardness is 51 and the specific gravity 3. o. The mean index of refraction of the secondary talc is found to be 1-5743 while that of the un- altered tremolite from which it is derived is 1.6241. Since specific gravity is relative to the weight of an object in air and its weight in water, it is a ratio and isn't expressed in units (such as kg/m³). Name: Named for the group type locality, Walitarama, Mariupol, Ukraine. Actinolite and Tremolite are two very similar minerals that form a series with each other and essentially share the same chemical formula.Actinolite has a greater presence of iron over magnesium, whereas Tremolite has a greater presence of magnesium over iron. Six different specimens in varying stages of alteration were examined and they revealed a gradual change in specific gravity and chemical composition. Catseye actinolite exists (S.G. 3.0, R.I. 1.63); when chatoyant material is cut, it exhibits a fine eye. Search for People. Get contact details and address| ID: 16617938291 ggpe » ggpe.mst.edu » Mineral Collection » Tremolite. Healing: Topaz stimulates the endocrine system and is used to treat isues related to disorders of the liver and gall bladder . Tremolite is a characteristic mineral of crystalline limestones, especially dolomitic limestones, but also occurs as an alteration-product of olivine in basic igneous rocks. It is a widespread amphibole and has been used in the past as asbestos. Density Specific Gravity: Specific gravity: 2.9 to 3.2 Melting Point: 950-1040 deg C (decomposes) Molecular Formula: Ca.4H2-O3-Si.5/2Mg Solubilities: Insoluble in water Insoluble in organic solvents. Cleavage Quality: Distinct. Hardness: 8 Specific Gravity: 3. Specific gravity measures the weight of a mineral specimen relative to the weight of an equal volume of water. Cleavage {110} is perfect. May be highly fibrous and included as an asbestiform mineral; considered carcinogenic if ground and inhaled. 1. Specific Gravity is the ratio expressing the weight of a mineral compared to that of an equal volume of water at 4° C. So, a specific gravity of 3 means that, at 4° C, one cubic centimeter of the material weighs 3 times as much as one cubic centimeter of water. Fermion Index: Fermion Index = 0.02 Boson Index = 0.98 : Photoelectric: PE Actinolite = 4.88 barns/electron U=PE Actinolite x rElectron Density= 14.73 barns/cc. Ulrich Henn and Claudio C. Milisenda, Gemmological Tables (2004) More from other references. Tremolite, a member of the amphibole group, is rare at Mont Saint-Hilaire. Since specific gravity is relative to the weight of an object in air and its weight in water, it is a ratio and isn't expressed in units (such as kg/m³). Walter Schumann, Gemstones of the world (2001) More from other references. Specific Gravity: 2.95 to 3.07. In actuality, the density of a mineral varies widely, even within a single crystal, due to the presence of impu­ rities, cracks, and bubbles. Radioactivity: It is usually white. note: Specific Gravity of Tremolite =2.98 gm/cc. Your handling of the material should be carefully considered. Common. Member of: Calcium Amphibole Subgroup > w(OH, F, Cl)-dominant Amphibole Group > Amphibole Supergroup. Crystal System: Monoclinic Colours: White, pale-yellow, pale-green, green Lustre: Vitreous Hardness (H): 5.0-6.0 Specific Gravity (S.G): 2.95-3.12 References: Von Bezing et al. 4. In gemology, specific gravity is, usually, determined through an apparatus based on Archimedes' Principle. There are about 4000 exceptional minerals, and every of these minerals has a completely unique set of bodily houses. Conditions to Avoid: Avoid generating dust. Fermion Index: Fermion Index = 0.02 Boson Index = 0.98 : Photoelectric: PE Tremolite = 2.61 barns/electron U=PE Tremolite x rElectron Density= 7.76 barns/cc. Luster is vitreous. The end-product of alteration was identified to be talc. High specific gravity is best indicator, colour and fracture are also helpful. Zircon. PHYSICAL CHARACTERISTICS: Color is usually colorless to dark blue and green. Member of: Taramite Root Name Group > Sodium-Calcium Amphibole Subgroup > w(OH, F, Cl)-dominant Amphibole Group > Amphibole Supergroup. Showing the single result Tremolite Tumblestones (Asbestos) £ 1.50; Appearance, Uses and History. Circular Radial Flow Gravity Thickener 18. Name: Named in 1789 by Johann Georg Albrecht Höpfner for the Tremola Valley (Val Tremola), Central St Gotthard Massif, Tessin, Switzerland, where the type material supposedly came from, according to the dealer from whom he … New RS Jewellers - Offering Tremolite Gemstone, Loose Gemstones, Astrological Stone, Lucky Stone, Colored Gemstone, Birthstones, Zircon Gemstone in Raj Nagar, Ghaziabad, Uttar Pradesh. Resembles tremolite, but has different cleavage. Retailer of Zircon Gemstone - Blue Zircon Gemstone, Ruby Gemstone, Sapphire Gemstone and Topaz Gemstone offered by New RS Jewellers, Ghaziabad, Uttar Pradesh. anthophyllite, tremolite, and actinolite (OSHA 1992). To measure specific gravity, a mineral specimen is first weighed in grams then submerged in a graduated cylinder filled with pure water at room temperature. Tests: Insoluble in acids. Tremolite is a form of Asbestos and is sold here for serious collectors only. It forms in thin, parallel fibers, sometimes producing a distinct cat's eye effect when cut in cabochons. Types of sedimentation tanks •Circular Radial flow •Conical Vertical flow •Rectangular horizontal flow 17. Entry for 'Tremolite' - 1911 Encyclopedia Britannica - One of 8 Bible encyclopedias freely available, this resource contained over 40 million words in nearly 40,000 articles written by 1,500 respected authors Actinolite is the chief constituent of nephrite (jade). History: Named in 1789 by Johann Georg Albrecht Höpfner for the Tremola Valley (Val Tremola), Central St Gotthard Massif, Tessin, Switzerland. GRAVITY SETTLING 15. Hardness is 5 – 6. Also used in paints, film and plastics. Read about company. Industrial/economical uses: Replacement for chrysotile asbestos in fire-resistant building supplies. For instance, the SG of Diamond = 3.52 (whereas the density of Diamond = 3.52 g/cm³). This definition … Crystal System is monoclinic, 2/ Crystal Habits include color-zoned prismatic crystals. Gemstone Specific Gravity . Tremolite. Arthur Thomas, Gemstones (2009) Optical Properties of Tremolite; Refractive Index: 1.599 to 1.637.
