"Dolomite" is a word that is used by geologists in two different ways: 1) as the name of the mineral dolomite; and, 2) as the name of a rock known as dolomite, dolostone, or dolomite rock. This page is about the mineral dolomite. If you are looking for an article about the rock, please go here. ADVERTISEMENT This is a metamorphic rock that is primarily composed of calcite or dolomite. O This is a coarse-grained rock that is composed of angular fragments in a fine-grained matrix. The matrix can be sandy or muddy, as in a debris flow. O This sample is dark green, brown to black, and has a nonmetallic luster.Considered to be one of the best examples of a pearly luster, the luster of crystalline dolomite is considered unique.

The name ‘fluorite’ comes from the Latin word ‘fluere’ that means “to flow.”. Fluorite melts easily and is used as a flux in the smelting of metallic ores. A ‘flux’ is a material used to help remove impurities from ore as it is refined into metal. Potassium feldspars are an important component of most felsic igneous rocks, pegmatites, low temperature hydrothermal veins and many metamorphic rocks, especially those that formed from the alteration of shale or felsic igneous rocks.Transparent dolomite crystals are difficult for faceters to cut. Dolomites have a low and variable hardness of 3.5 to 4, which varies along its four crystal axes, as well as perfect cleavage. These factors also make it a fragile stone for jewelry use. They are more liable to scratch and break than most jewelry stones. PE Dolomite = 3.13 barns/electron U=PE Dolomite x rElectron Density= 8.86 barns/cc.

It is the only important ore of mercury. It has a bright red color that has caused people to use it as a pigment, and carve it into jewelry and ornaments for thousands of years in many parts of the world. Because it is toxic, its pigment and jewelry uses have almost ...Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2. It occurs widely, often in association with limestone and evaporites , though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 million years in …Question: Following all instructions and guidelines for submitting assignments, complete the following assignment.

Orthoclase has cleavage planes that meet at about 90 o, like other feldspars.Study with Quizlet and memorize flashcards containing terms like Albite, Amphibole, Anorthite and more.Dolomite in Hand Sample. If you’ve taken an intro Geology class (and I bet you have), you’ve probably heard that chalk is made up of the calcite tests of algae called coccolithophores. Well, sometimes it’s true.
