The 5 Characteristics Of A Mineral

1 What is salt? A naturally occurring solid that has a crystalline structure and unique structure. Example: khoti

Solved 1. Rocks And Minerals Exist In Our Daily Life

It should happen naturally. It must be inorganic. It should be strong. It must be crystalline (a repeating arrangement of atoms). It should have a specific product.

7 Inorganic Solid: This means that the mineral cannot be from pre-existing material. Not water or gas at “normal” temperatures. Non-Example: Coal – This is organic because it comes from plants that lived millions of years ago.

The repetitive process of mineral particles that form. Most minerals have the shape of rock candy. There are 6 different crystal machines. They are divided by # of crystal faces and angles

Isometric (cubic) Pattern: Magnetite Hexagonal Pattern: Quartz-Tetragonal Pattern: Rutile-Orthorhombic Pattern: Sulfur Monoclinic Pattern: Azurite-Triclinic Pattern: Microclinic Feldspar

16 1. Scratch test The type of powdery salt that remains when applied to a sensitive area. Example: pyrite looks like gold but has a green-black streak (called “dumb gold”) Writing in class with a pencil = graphite!

17 2. Luster Describes how light is reflected from the surface of a mineral. What does it look like? Light Colors: Metal Example: Galena Glass Example: Topaz Waxy, Oily, Pearl Example: Opaque Talc Example: Silky Graphite Example: Malachite Earthy Example: Hematite

Use it properly to gain mass. Put salt in H2O to find the amount of water it moves. This quantity is the quantity of salt. To find density, divide the mass by the volume. Example: sample of olivine mass = 237 g Volume = 72 cm3 Density = 237 g/ 72 cm3 = 3.3 g/cm3

Volume = (final volume – initial volume) Or … ml – 900 ml = 20 ml Another way to express ml is cm3. So……. Density = weight (g) / volume (cm3) Save your calculations in Comp. a book.

What Are Minerals?

Cut shells in different shapes eg: quartz tips eg: copper and iron are crushed eg: clay.

A scale of 10 minerals from the softest to the hardest. At this level, you can compare unknown minerals with minerals. Hardness can be measured by kicking Salt can scratch any soft mineral Can also scratch any hard mineral Softest mineral = talc Hardest mineral = diamond

Between 2,000 and 3,000 have been identified. Some are “natural materials” – made from only one element, such as sulfur, gold. copper and graphite (carbon) Most of these are chemicals, especially the silicate group (Si, O). Other important groups are oxides, carbonates, and sulfides

How The Mohs Scale Ranks Hardness

Mineral group materials and properties Examples Silicates are mainly O and Si groups Quartz Mica Feldspar Mica QUARTZ

Examples of mineral properties Carbonates C and O form karst topography that includes caves Calcite (SiO3) Calcite with duptite

10 examples of properties of the group of minerals Native Elements from the periodic table Gold (Au), Diamond (C), Silver (Ag)

The 5 Characteristics Of A Mineral

Hardness of the crystal shape (shape) light color / low density or specific gravity – acid reaction – fluorescence – alkaline taste magnetism

Copper: Mineral Information, Data And Localities

Some minerals have more than one color, many types of minerals can have the same color

Mohs scale of hardness from 1 (talc) to 10 (diamond) Quartz (the most common mineral with many dust particles) is 7

18 The color of the powder streaks when applied to a streak plate (unglazed porcelain) the “real color” may be the same as a hand-made pattern or some salt should be softer than the streak plate.

19 break/break Some salt breaks on a flat surface when hit hard – break.

All nutrients have density (mass/volume), but some are very dense. Specific gravity is the amount of salt compared to the amount of water (1 g/ml)

Acidity: some salts dissolve acids by foaming (e.g. carbonate salts) Odor: some have a distinct smell (e.g. sulphur) Taste: some taste (e.g. salt-sensitive halite) Magnetic attraction (e.g. magnets and other irons) . minerals) Fluorescence is , when minerals glow under UV light

In geology, minerals are naturally occurring compounds with a defined chemical composition and crystal structure. Most minerals are unstable, although some mineralogists allow minerals to be organic or biological rather than geological processes. The word mineral comes from an ancient Latin word

, meaning mine or mine. Several thousand minerals are known. About one hundred of them are stone sections.

Kyanite: Mineral Information, Data And Localities

Minerals include naturally occurring substances such as solids (organic) and chemicals. Unlike most chemicals, minerals usually contain two or more elements that occupy the same position in the crystal structure of the mineral. For example, the formula for the mineral mackinawite is (Fe, Ni)

The words “stone” and “mineral” do not mean the same thing. Salt is a solid natural substance with its own structure and composition. A rock contains one or more minerals or mineraloids. Therefore, a stone can be a mineral and vice versa. However, some mineral samples are not rocks. Most rocks contain minerals and/or mineraloids. For example, granite (rock) mainly consists of quartz, feldspar and plagioclase. Ore is a rock that contains a lot of minerals.

Most gemstones are made of minerals, but not all minerals are gemstones. A precious stone or precious stone is cut and polished hard, usually a mineral crystal. Although all minerals have a crystalline form, sometimes they appear as solid grains. For example, rubies and sapphires are made from the mineral corundum.

Some natural solids are similar to minerals but do not meet all the requirements of definition. Mineraloids are natural substances such as minerals that do not have a fixed mineral content or do not have a crystalline form. Obsidian and opal are good examples of mineraloids that are amorphous rather than crystalline. Pearl is a mineraloid because it contains elements associated with calcite or aragonite in no particular ratio.

Chapter 5 Objectives Define Mineral.

Identifying minerals is a difficult task because two rocks may look the same at first glance. Here are some things that distinguish different minerals.

The two main types of minerals are silicates and non-silicates. This is because the earth’s crust is made up of silicates, which are minerals containing silicon and oxygen.

Organic minerals are in a class of their own. These materials contain organic carbon (ie carbon bound to hydrogen) but are formed through geological processes. An example of an organic mineral is whewellite (CaC2) What is a mineral? have a definite shape and volume Must have a crystalline form Must have a specific chemical composition (composed of elements combined to form a group)

The 5 Characteristics Of A Mineral

Stones are compounds, not compounds. Stones do not have a specific shape. Stones cannot be divided by characteristics. Stones are classified according to their composition.

Learn more about minerals based on your body composition. Physical requirements: hardness – line color – density – crystal breakdown – fluorescence.

Use the Moh’s hardness scale to determine how hard a mineral is. This is a scale where 1 is the softest and 10 is the hardest.

It is found by dividing the QUANTITY of the salt by VOLUME, VOLUME is found by measuring the amount of WATER that the salt DISSOLVES when placed in a container full of WATER.

When minerals form, they form atom by atom. As these atoms pile up on top of each other, they tend to follow a certain pattern. This model forms a crystal

Five Characteristics Of A Mineral

Cubic (square) Tetragonal (long square) Hexagonal (flat top and bottom, 6 sides) Orthorhombic (rectangle) Monoclinic (offset rectangle) Triclinic (rounded rectangle on two sides)

18 Magma Minerals When magma cools deeply, it can take months or years for crystals to form. Slow cooling results in the formation of large crystals. Magma near the surface cools rapidly, causing particles to form.

Liquid water and its constituents pass through cracks in the ocean floor and when they reach the temperature of the underground magma, they flash. The crystals are carried to the top of the eruption, placing the crystals on top of the mountain. These include: veins of silver, veins of gold, veins of copper
