Comparing and Contrasting Mineral Properties

BACKGROUND: Minerals can be identified by various properties.Students will become familiar with mineral characteristics the more they study and examine minerals. Characteristics commonly used to identify minerals include color, hardness, crystal shape, texture, cleavage, density (or specific gravity) and magnetism.The students should be familiar with at least some

Types of Stone for Carving

Fine detailed carving is better left to other types of stone. Diamond saws and cup grinders cut through granite quite easily and can speed up the carving and finishing process. Granite comes in a wide variety of colors, and the crystal size can vary from large and coarse to very fine and dense. Limestone is composed primarily of the mineral

Hardness is a measure of a mineral's resistant to abrasion. This property is easily determined and is used widely for field identification of minerals. More than a century ago. Friedrich Mohs (1773-1839), a German mineralogist, assigned arbitrary relative numbers to ten common minerals in order of their hardness.

Mineral

Minerals form in many ways. The mineral halite, which is used as table salt, forms when water evaporates in a hot, shallow part of the ocean, leaving behind the salt it contained. Many types of minerals are made when molten rock, or magma cools and turns into a solid. Talc, a mineral that can be used to make baby powder, forms deep in Earth as high pressure and temperature

Mineral

A rock is an aggregate of one or more minerals or mineraloids. Some rocks, such as limestone or quartzite, are composed primarily of one mineral – calcite or aragonite in the case of limestone, and quartz in the latter case. Other rocks can be defined by relative abundances of key (essential) minerals; a granite is defined by proportions of quartz, alkali feldspar, and plagioclase feldspar.

Talc is a foliated mineral and associated with metamorphic rocks. It is an alteration product from the metamorphism of minerals such as serpentine, pyroxene and amphibole.

Identifying a Mineral Using Mohs Hardness Scale

The hardness of a mineral is often used by geologists to help determine the identity of a sample. The Mohs Hardness Scale as developed by a German geologist, Friedrich Mohs, in 1812. The Mohs scale is a relative scale which lists the hardness of 10 common minerals. Talc, #1 on the scale is the softest and diamond, #10, is the hardest.
