What is an actinolite?
An actinolite is a mineral with monoclinic crystals.
Is all actinolite asbestos?
No, actinolite is a mineralogical name for an amphibole silicate mineral. Some forms of this mineral are asbestiform and some are not.
What is meant by the term actinolite?
Actinolite is a type of mineral. The name comes from the Greek 'aktis', which means 'beam'. Actinolite takes several forms. One type is a dangerous form of asbestos, but other types are used as gemstones.
What is Asbestos make up?
Asbestos is a naturally ocurring mineral. Other names are chrysotile, amosite, crocidolite, tremolite, actinolite and anthrophyllite.
Would you give an example of a mineral?
Gold and copper are native elemental minerals, pyrite (Fool's Gold) is a mineral, as is calcite, galena, chalcopyrite, quartz, actinolite, sulphur, feldspar, mica, tourmaline, corundum, epidote, fluorite, and diamond.
Is pounamu rock a type of igneous rock?
Pounamu is the Maori name for several types of hard, durable and highly valued nephrite jade and bowenite found in New Zealand, thanks to Wikipedia. It is found only on the South Island.Be aware, however, that as nephrite jade is, by definition, a mixture of amphiboles with an interlocking microcrystalline structure, pure actinolite or pure tremolite minerals, it is therefore not jade.
How can you tell if it is jade?
Jade is an ornamental stone. The term jade is applied to two different metamorphic rocks that are made up of different silicate minerals:Nephrite jade, consists of a microcrystaline interlocking fibrous matrix of the calcium, magnesium-iron rich amphibole mineral series tremolite (calcium-magnesium)-ferroactinolite (calcium-magnesium-iron). The middle member of this series with an intermediate composition is called actinolite (the silky fibrous mineral form is one form of asbestos). The higher the iron content the greener the colour.Jadeitite, a rock consisting almost entirely of jadeite, a sodium- and aluminium-rich pyroxene. The gem form of the mineral is a microcrystaline interlocking crystal matrix
What is the mineral present of marble?
marble is a metamorphic rock and was formed by regional or contact metamorphism it is a metamorphism of limestone and dolostone. the composition is calcite and/or limestone(sedimentry rock made od calcite)
Where was jade discovered?
Nephrite jade is extremely abundant, and found all over the world. Mostly in Canada, but also China, New Zealand, USA, Taiwan, Russia. Jadeite jade is much less abundant and therefore is much more expensive, found in mostly in Myanmar, and some in the USA.
What are some examples of silicate and nonsilicate minerals?
Important examples of silicate mineral species include forsterite (in the olivine group), almandine (in the garnet group), epidote, schorl (in the tourmaline group), enstatite (in the pyroxene group), actinolite (in the amphibole group), muscovite (in the mica group), albite (in the feldspar group), stilbite (in the zeolite group), and quartz. Important examples of non-silicate mineral species include calcite, gypsum, fluorite, hematite, galena, and gold.

What kinds of jewels are in the world?
Diamonds, Rubies, Emeralds, Opal, and Sapphires are some gemstones that come to mind when we think of jewels. At a quick glance I can count more than 130 gemstones in my reference book. Gemstones are broken down by the scientific community into 10 specific mineral classes. To keep this simple, we will use the common terms for gemstones of precious, semiprecious, organic, and exotic. The following list is not all-inclusive, but is a good start. PRECIOUS gemstones are: diamond, sapphire, ruby, and emerald. LIST OF SEMIPRECIOUS GEMSTONES (PARTIAL LIST): Amber (Amber) Amethyst (Quartz) Ametrine (Quartz) Apatite (Apatite) Aquamarine (Beryl) Agate (Chalcedony) (red-banded agate is shown under sard) Alexandrite (Chrysoberyl) Azurite Benitoite (Benitoite) Beryl (Beryl) Bloodstone (Chalcedony) Carnelian (Chalcedony) Chalcedony Chrome Diopside (Diopside) Chrysoberyl (Chrysoberyl) Chrysoprase (Chalcedony) Chrysocolla Citrine (Quartz) Diamond (Diamond) Emerald (Beryl) Fluorite Garnet (Almandine, Andratite, Grossularite, Pyrope, Spessartine, Uvarovite) Heliodore (Beryl) Heliotrope (Chalcedony) Hematite Hessonite (Grossularite) Hiddenite (Spodumene) Iolite (Cordierite) Jade (Jadeite or Nephrite) Jasper (Chalcedony) Kunzite (Spodumene) Kyanite Labradorite Lapis Lazuli (Lazurite) Malachite (Malachite) Moonstone (Albite, Microcline Feldspar, Orthoclase, Plagioclase) Morganite (Beryl) Onyx (Chalcedony) Opal (Opal) Pearl Peridot (Olivine) Quartz (Quartz) Rhodochrosite (Rhodochrosite) Rhodolite (Almandine-Pyrope Garnet) Rock Crystal (Quartz) Rose Quartz (Quartz) Ruby (Corundum) Sapphire (Corundum) Sard (Chalcedony) Sardonyx Sinhalite (Sinhalite) Sodalite (Sodalite) Spinel (Spinel) Sugilite (Sugilite) Sunstone (Oligoclase Feldspar) Tanzanite (Zoisite) Titanite (Sphene) Topaz (Topaz) Tourmaline (Tourmaline) Tsavorite (Grossularite) Turquoise (Turquoise) Zircon (Zircon) ORGANIC GEMSTONES INCLUDE: ORGANIC: Amber Copal (young amber 3-7 million years old) Coral Pearls LESSER KNOWN SEMIPRECIOUS GEMSTONES: (Not commonly known, but are becomingly increasingly more popular especially in custom designed jewelry.) Amblygonite Andalusite Apatite Axinite Benitoite (Benitoite) Beryllonite Brazilianite Cassitierite Cerussite Danburite Diopside Dioptase Dumortierite Enstatite Epidote Euclase Hambergite Hemimorphite (also called Calamine) Idocrase Kornerupine (also called Prismatine) Kyanite Lazulite Petalite Phenakite Prehnite Scapolite Scheelite Serpentine Sinhalite (Sinhalite) Smithsonite (also called Bomamite) Sphalerite Sphene (Titanite) Stitchite Ulexite Variscite (also called Utahlite) EXOTIC GEMSTONES: (Called this for a number of reasons. Many of these are hard to fine and not available in large quantities, others are brittle or break easily and therefore are not suitable for jewelry. These gemstones are generally owned by collectors and do not make it to the marketplace.) This list could be quite long, I have included only a few to give you an idea of some that are in this category. Actinolite Ametrine Aragonite Bixbite Clinohumite Diasphore Dolomite Hypersthene Labradorite Muscovite Olioclase Periclase Phosphophyllite Pietersite Rutile Willemite Wulfenite
