Earth’s crust is loaded with minerals – some of them common, some of them very rare. Even those that don’t cost hundreds or thousands of dollars in the gem variety are valuable and useful. All minerals are natural, inorganic solids that have interesting crystalline structures. Each mineral is a specific combination of elements. Minerals are usually identified by certain physical properties such as hardness, streak, luster, mass, form, cleavage, feel, smell and taste.

Below is a mineral hardness scale and two tables that contain physical properties of common minerals, all of which can be used to answer the questions on the following page.

Background Information

Scientists have identified more than 2000 different kinds of minerals. However, most minerals are very rare. Over 95 percent of the Earth’s crust is made of rocks that are composed of about a dozen minerals. These common minerals are called rock-forming minerals. While minerals can vary a great deal in their chemical makeup and the forms in which they are found, most common minerals can be identified by observing a few of their basic properties.

In this investigation you will observe the physical properties of some common rock-forming minerals and use these properties to identify the minerals. To do so, you will have to test for the physical properties described below.

SOME PHYSICAL PROPERTIES OF MINERALS

Hardness is the resistance of a mineral to scratching. A mineral will scratch any other substance less hard than itself.

|Table of Hardness of Common Items |

|Item |Approximate Hardness|Comments |

|Fingernail |2.5 |This means a fingernail will scratch the mineral. |

|Copper Penny |3.0 |This means nothing softer than a penny will scratch the mineral. |

|Steel Nail |5.5 |This means nothing softer than a steel nail will scratch the mineral. |

|Glass |6.0 |This means the mineral will scratch the glass. |

Streak is the color of a fine powder of a mineral. Rubbing a mineral against a piece of dull tile, or streak plate, will generate enough powder to enable you to determine its streak.

Cleavage is the quality of a mineral that causes it to split, leaving smooth, flat surfaces. When a mineral does not split to leave smooth, flat surfaces, the break is called a fracture. You can easily observe whether a mineral shows cleavage or fracture.

Minerals have a characteristic crystal shape. A crystal is a solid that has flat surfaces, or faces, arranged in a definite shape. There are six crystal systems, or categories of crystal shapes: cubic, hexagonal, orthorhombic, monoclinic, tetragonal and triclinic. Most minerals belong to only one crystal system. A few, however, belong to more than one system. Serpentine crystals, for example, may be monoclinic, orthorhombic or hexagonal. Although the crystals in each system share certain basic mathematical characteristics, they may appear quite different from one another. Consider three minerals whose crystals belong to the cubic system: halite, diamond and garnet. Halite crystals, which are shaped like cubes, have six square faces. Diamond crystals have eight triangular faces. Garnet crystals have twelve faces, each of which have five sides.

Luster is the way a mineral reflects light. Minerals may be described as having metallic luster or nonmetallic luster. Metallic luster is the shine associated with a freshly polished metal surface. Nonmetallic luster may be described by terms such as glassy, brilliant or greasy.

Density is the mass per unit volume of a substance. Density can be estimated by determining a sample’s heft, or how heavy it seems for its size. Samples that seem heavy for their size are described as dense, while samples that seem light for their size are described as not very dense.

Some minerals have special properties that can be used to identify them. For example, a few minerals are magnetic and will be attracted to a magnet.

Problem

How can the physical properties of minerals be used to identify them?

Materials (per group)

Set of common mineral samples

Magnet

A Gem of a Puzzle

Imagine the following situation. Hearing that you have gotten pretty good at identifying minerals, a wealthy (& rather eccentric) gem dealer has challenged you to identify three beautifully cut gems. If you can correctly identify the gems, you get to keep them.

As you can see in the accompanying figure, the gem dealer has presented you with the three gems, a table of information, and five vials containing thick, rather smelly liquids.

Gem Density

(g/cm3)

beryl 2.7

corundum 4

cubic zirconia 5.7

diamond 3.52

quartz 2.65 A B C D E

topaz 3.56 2.65 2.71 3.06 3.52 4.00

zircon 4.7

Applying Concepts

1. Describe the procedure you plan to use to identify the gems.

2. What results would you expect to obtain for sapphire (corundum)? For quartz?

3. Suppose that one of the gems sinks slowly in solution C, floats on the top of solution E, and stays at

whatever depth you put it in solution D. What mineral is this gem made of?

4. Explain how you can tell the difference between cubic zirconia and zircon using only the materials

available to you. (It can be done!)

Each year, Professor Rockford offers his Geology 101 students the opportunity to earn extra credit by bringing samples of oxide, silicate and sulfide minerals to class. Over the years, many students have attempted this task, but it takes more than garden-variety quartz to earn the professor’s bonus. This spring, Bebe and four other students each brought a different oxide (brookite, goethite, magnetite, rutile or spinel), a different silicate (albite, benitoite, leucite, prehnite or rhodonite) and a different sulfide (argentite, bornite, chalcocite, millerite or pyrite) to class. Not only did the five students get the extra credit, but they rocked the professor’s world! From the information provided, determine the oxide, silicate and sulfide samples each student brought to class.

1. Marnie brought magnetite, but not benitoite.

2. Rosetta isn’t the student who brought both goethite and pyrite.

3. One student brought both rutile and leucite, but not millerite.

4. Landon brought both rhodonite and argentite, but not brookite.

5. Axel brought both prehnite and chalcocite.

Label the Rock Cycle and identify the processes that are required for each phase here:

| | | | |

|Group |Sub- |Rock |Description |

| |group | | |

| | |Granite |composed mostly of quartz and feldspar and sometimes biotite or hornblende; usually |

|IGNEOUS |Intrusive | |light-colored; an coarse-grained, slow-cooling intrusive rock |

| | |Basalt |a dark intrusive rock rich in iron and magnesium minerals and feldspar; the ocean floor is |

| | | |composed mostly of basalt; generally cools slowly forming large crystals |

| | |Obsidian |volcanic glass, usually black, cools so quickly, it doesn’t form crystals; a fine-grained, |

| |Extrusive | |fast-cooling, extrusive rock |

| | |Pumice |a natural volcanic glass with many holes, cools so quickly no visible crystals form, may float in|

| | | |water; a fine-grained, fast-cooling extrusive rock |

| | |Sandstone |distinct grains of sand cemented either poorly or tightly cemented together; fine-grained; white,|

|SEDIMENTARY |Clastic | |reddish, or brown, rock will usually scratch glass; usually made of small quartz particles, can |

| | | |be formed in deserts, beaches, or riverbeds |

| | |Shale |microscopic grains of compacted mud; sometimes gets muddy when wet and rubbed; usually gray, but |

| | | |can be black, green, tan, or red; rock can usually be scratched by fingernail; formed when clay |

| | | |particles are deposited when water stops moving; can sometimes be split into flat pieces |

| | |Conglomerate |formed when rounded river rocks or pebbles are cemented together by river sand and mud; usually |

| | | |will scratch glass; rocks are rounded by the wearing away of the edges by running water causing |

| | | |the pebbles to hit each other |

| | |Limestone |consists mostly of calcium carbonate (CaCO3); it is the combined equivalent of mud, sand and/or |

| |Non-clastic | |shell fragments; very abundant |

| | |Gypsum |rock composed mostly of the mineral gypsum; forms in thick, extensive beds and is frequently |

| | | |associated with halite |

| | |Gneiss |coarse textured rock, made from granite (an igneous rock) dark and lights minerals arranged in |

|METAMORPHIC |Foliated | |alternating bands of light and dark color |

| | |Slate |fine (microscopic) textured rock; formed from shale (sedimentary rock) or from clay; used to make|

| | | |flagstones for patios or walkways, used to be used for chalkboards |

| | |Schist |a medium to coarse textured rock; formed from slate (a metamorphic rock), basalt or granite |

| | | |(igneous rocks); the minerals are visible to the unaided eye, and tend to overlap; mica (biotite |

| | | |or Muscovite) are visible |

| | |Marble |fine- to coarse-grained rock, formed primarily from limestone (a sedimentary rock); carbonate |

| |Non-foliated | | |

| | |Quartzite |a medium textured rock; formed from sandstone (a sedimentary rock); can be pink or light brown, |

| | | |depending on the color of the original sandstone |

These are the facts you should know…:

A mineral is found in nature, inorganic, solid, with a definite chemical composition and structure.

Mineral properties depend on their atomic structure.

Minerals may be identified by their physical properties such as hardness, color, luster, and streak.

Most rocks are made of one or more minerals.

Some major rock-forming minerals are quartz, feldspar, calcite, and mica.

Ore minerals include pyrite, magnetite, hematite, galena, graphite, and sulfur.

The major elements found in Earth’s crust are oxygen, silicon, aluminum, and iron. The most abundant group of minerals is the silicates, which contain silicon and oxygen.

Igneous rocks are classified by composition and texture.

Igneous Rocks are produced by the cooling of magma (cooled below Earth’s surface) or lava (cooled above Earth’s surface).

Fast cooling = Extrusive - Texture includes small, fine-grained mineral grains, glassy, air holes present. (pumice, basalt, obsidian)

Slow cooling = Intrusive- Texture includes coarse or large mineral grains. (granite)

Metamorphic formed by heat and pressure or chemical action.

Metamorphic include foliated (banded) and non-foliated.

Foliated rocks have bands of different minerals. Examples are slate, schist, gneiss.

Non-foliated rocks have little or no banding and are relatively homogenous throughout and include marble and quartzite.

Limestone morphs into marble.   Sandstone morphs into quartzite.

Sedimentary rocks form from rock fragments, organic material, or chemical precipitation.

Sedimentary are found in flat layers or strata. Fossils are found in these layers.

Sedimentary subclasses include clastic, organic, and chemical.

Limestone is formed both chemically and organically.

Clastic rocks are made of fragments- conglomerate, sandstone, and shale.

Non-clastic sedimentary rocks include limestone and rock salt.

Coal formation from softest to hardest- Peat, Lignite, Bituminous, Anthracite.

Non-renewable resources are renewed very slowly or not at all. Non-renewable resources include coal, oil, and minerals.

In Virginia, major rock and mineral resources include coal for energy, gravel and crushed stone for road construction, and limestone for making concrete.

Nearly all fossils are found in sedimentary rocks.

Interpret the rock cycle diagram.

Classify the following rock types as igneous, metamorphic, or sedimentary: pumice, obsidian, basalt, granite, sandstone, conglomerate, shale, limestone, slate, schist, gneiss, marble, and quartzite.

When finished with this unit, you should be able to…:

Determine if a substance is a mineral based upon the given characteristics.

Identify the following minerals based on their specific chemical and physical properties (color, hardness, streak, color, luster, and breakage): quartz, feldspar, mica, calcite, bauxite, hematite, galena, halite, graphite, pyrite, sulfur, diamond and talc and know their commercial use(s).

List ways that minerals are important to human wealth and welfare.

Classify rocks into the three major groups by the processes that formed them.

Explain the rock cycle diagram and identify the processes by which all rocks are formed and how materials are recycled through time.

Identify the following rocks on the basis of mineral content and texture: Igneous – pumice, obsidian, basalt, granite; Sedimentary – sandstone, conglomerate, shale, limestone, gypsum; Metamorphic – slate, schist, gneiss, marble, quartzite.

Distinguish between a rock and a mineral.

Discuss why minerals and rocks are nonrenewable resources and are limited. Observe evidence of ancient, often extinct life preserved in sedimentary rock.

Concept Checks

Review the list of terms below. For each one, determine how well you understand the term or the concept that it represents after having completed the review questions on the previous pages.

If you understand it thoroughly, place a check (() in the space next to it. If you have heard of it but are less certain about it, place a plus (+) in the space next to it. If you’ve never heard of it or simply can’t seem to understand it, place an ‘o’ in the space next to it. Let the ‘o’ items help focus your studying.
