The mineral is typically colorless or white, but may also be light blue, dark blue, purple, pink, red, orange, yellow or gray depending on inclusion of other materials, impurities, and structural or isotopic abnormalities in the crystals. It commonly occurs with other evaporite deposit minerals such as several of the sulfates, halides, and borates.
The apatite Mineral Group. Apatite is the most common phosphate mineral, and is the main source of the phosphorus required by plants. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite. (These biological Apatites are almost exclusively the Hydroxylapatite type.)...
Optical Properties of Minerals: Luster, Light Transmission, Color Streak. Minerals are conveniently identified based on their physical properties. These properties include luster, ability to transmit light, color and streak. This lesson will describe each of these properties and examples of each.
Nov 15, 2008· So from Pearl, we get pearly luster, from diamond we get adamantine lustre, from metals we get metallic luster etc. Hardness is a physical property of a mineral, determined by reference to an empirical scale of standard minerals (Moho's scale). As per this property a harder mineral can always scratch any mineral softer than it.
Certain properties are used to identify minerals. Some are visible to the naked eye and others require tests. These properties are luster, hardness, color, streak, cleavage and crystal shape. Minerals can be refined to have a variety of uses, such as making jewelry, .

Jan 19, 2013· Mineral Luster and Transparency 1. Properties of Minerals: Luster The way light reflects off of the surface of a mineral 2. Dull/Earthy Very dull Mainly in minerals that are porous Kaolinite, orthoclase 3. Waxy Like the surface of a candle Chalcedony 4.
Lapis lazuli is a rock, which means it's an aggregate of several minerals. This ancient gem contains three minerals in varying amounts: lazurite, calcite, and pyrite. Sometimes, it also contains one or more of the following: diopside, amphibole, feldspar, and mica.
Start studying Chapter 3. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
A mineral that reflects light the way glass does has a vitreous (or glassy) luster; a mineral that reflects light like chrome has a metallic luster. There are a variety of additional possibilities for luster, including pearly, waxy, and resinous (see pictures in Figure 5).
Talc is usually green, white, gray, brown, or colorless. It is a translucent mineral with a pearly luster. It is the softest known mineral and is assigned a hardness of 1 on the Mohs Hardness scale. Talc is a monoclinic mineral with a sheet structure similar to the micas. Talc has perfect cleavage that follows planes between the weakly bonded ...

Luster (or lustre) is a description of the way light interacts with the surface of a crystal, rock, or mineral. For example, a diamond has an adamantine lustre and pyrite has a metallic lustre. The term is also used to describe other items with some kind of sheen (for example, fabric, especially silk and satin, or metals).
Lustre or luster is the way light interacts with the surface of a crystal, rock, or word traces its origins back to the Latin lux, meaning "light", and generally implies radiance, gloss, or brilliance.. A range of terms are used to describe lustre, such as earthy, metallic, greasy, and, the term vitreous (derived from the Latin for glass, vitrum) refers to a glassy ...
Physical properties of minerals allow us to distinguish between minerals and thus identify them, as you will learn in lab. Among the common properties used are: Habit shape ; Color ; Streak and (color of fine powder of the mineral) Luster metallic, vitreous, pearly, resinous (reflection of light)

In this poem "Education Gives Luster to Motherland", Jose Rizal extols the citizenry to strive towards education in order to give glory to the country. Jose Rizal loved his Motherland. Even at a very young age, he cultivated an intense affection towards his country and his people.
Mineral Luster. Luster is a description of the way a mineral surface looks when light reflects off of the surface. Luster has two categories, metallic and nonmetallic. Metallic Luster refers to minerals that look like a shiny metal. Examples include galena, pyrite, magnetite, and some varieties of hematite.
THE DIFFERENCE BETWEEN ROCKS MINERALS It is not easy to tell the difference between rocks minerals because there are so many kinds of them. It takes years of study to be able to accurately identify a mystery rock and even then rockhounds want to know where the specimen.
