Tephrite and Detail Informations about Tephrite

Tephrite : Tephrite    is   an    igneous,   volcanic (extrusive)   rock,    with alphanitic to porphyritic            texture. Mineral content is usually abundant feldspathoids (leucite or nepheline), plagioclase, and lesser alkali feldspar. Pyroxenes (clinopyroxenes) are common accessory minerals. Quartz and olivine are absent. Occurrences include leucite nepheline tephrite from Hamberg bei Neckarelz near Heidelberg, Germany, phonolite-tephrite at Monte Vulture, Basilicata, Italy and basanite–tephrite intrusions in Namibia.

Tephrite and Detail Informations about Tephrite

Tephrite : tephrite is an igneous rock of basaltic character that generally occurs as lava flows, but occasionally as minor intrusions. Its essential constituents are calcic plagioclase and clinopyroxene in association with nepheline, leucite, or analcime. With the addition of olivine to this mineral assemblage, the rock is termed as basanite, a term used by the Greeks of classical times to describe touchstones used in testing the purity of alloys of gold and silver. Both tephrites and basanites vary in color from gray to black. They are characteristically porphyritic with a very fine-grained groundmass. Some are holocrystalline but in many the groundmass is hypocrystalline. Because of this the feldspathoids are commonly occult in the groundmass. Such rocks are often referred to as tephritoids and basanitoids with the norm calculated from a chemical analysis needed before they can be classified.

Tephrite : There is a huge value for natural stones and it is more than a momentary measures. The value of these stones raised because of its properties like longevity, ease of maintenance, permanence and stability. Natural stones are becoming more available and affordable because of advancing stones quarrying and processing technology that is getting improved over the years. New technology, automation, are allowing fabrication to cut natural stones thinner, faster, and more consistently with less cost over the time period. Development of anchoring technologies and systems make installation easier, quicker, and more secure. Likewise, regular stone is easy to tend to, has an appearance that truly enhances with age and can endure forever.

Tephrite : The choice of stone will depend on a variety of considerations such as the client or homeowner’s aesthetic preferences, budget, intended use, and technical requirements for the specific application. There are many visual similarities among different materials, but few can naturally achieve the sustainable qualities of natural stone. So, when specifying stone to meet sustainability goals and requirements it is important to have a thorough and clear understanding of how to ask for what you need, and have a clear set of communications for both quality assurance and quality control on the project. It starts with setting goals for the project and determining how they can be met with stone, then coordinating the selection, fabrication, finishing, installation methods, and maintenance that will help you meet those goals.

  2. Durability 
  3. Green Attributes 
  4. Unique 
  5. Value


There is enormous diversity of natural stones that encourages limitless designs potential. Aesthetically, everything is based on your views, on your imaginations. Stones are formed within the earth crust. Earth has its major contribution in variety and to enhance the creativity its provides. And this stones are having different properties, designs etc that cannot be duplicated in any form and anywhere.


Almost all stones contains the nature of durable. Especially natural stones exhibits a durability that cannot be found in other building materials. There is always a emotional connection with emotional connection to building and monuments build in stones that carries a great meaning because of history and a legacy of man kind through the ages.

Green Attributes

Natural stones like granite, marble, limestone, slate and sandstone, among other possess innate characteristics that contribute towards LEED that is Leadership in energy and environment design. Stones are considered as low embodied energy, ready availability as a natural stone’s low embodied energy, ready availability as a naturally occurring material. Some of the high properties of stones are high thermal capacitance, no off-gass to impair indoor air quality, exceptional durability for low maintenance and structural permanence. Use of natural stones shows the care, love for mother nature and environment.


Natural stones are made from quartz-like particles called silica etc. Almost most of the stones are unique posses different design etc. Designing a project with natural stone show your care for environment, it will always stand out and reflect the passion, taste and personality of the designer along with the designs. Natural stones cannot be faked, mimicked and manufactured in any laboratory so it is one of the kind of building material and unique.
