Laboratory 2 Rocks and Minerals Laboratory Pamela J. W. Gore Department of Geology, Georgia Perimeter College Clarkston, GA 30021 In this lab you will learn about rocks and minerals. Minerals are the building blocks of rocks, and rocks are the building blocks of the Earth's crust. This lab will introduce you to some of the major rock-forming minerals, and to the three major groups of rocks - igneous, sedimentary and metamorphic. This course will go into more detail with sediments and sedimentary rocks in later labs because it is the sedimentary rocks which record the history of life on Earth. We can also learn to "read the rock layers" to learn many things about the conditions on Earth in the far geologic past, such as ancient climates, tectonic settings, and depositional environments. BASIC DEFINITIONS Minerals Minerals are: Naturally occurring Inorganic Solids Minerals have a definite chemical composition Minerals have an orderly internal crystal structure Minerals are the building blocks of rocks. Each mineral has different physical and chemical properties which allow it to be identified. Physical properties you will use to identify the minerals include color, hardness, luster, cleavage, magnetism, reaction to acid, etc. Rocks An aggregate of one or more minerals. Rocks are the building blocks of the Earth's crust. The Earth's continental crust is dominated by granite, and the oceanic crust is dominated by basalt. Both of these are igneous rocks.

Columbite (Fe,Mn)(Nb,Ta) O Iron Manganese Niobium Tantalum Oxide New Columbite specimens are currently available from Western Australia. Recent deep mining undertaken by us uncovered exceptional pieces. The mine entrance was then covered up to make it safe and environmently stable. We have geological mapped the mine so know where the best crystals were located. These specimens are the only pieces that will come from this locality for a long time. A broad range of columbite forms for all budgets are available on and off matrix. Do you have a columbite specimen in your collection? Once you go black, you never go back! All offers on specimens. New specimens will be continually posted so check back when you can for a browse or before a specimen that you are interested in is sold. Crystal size: 61 x 26 x 13 mm and 47 x 20 x 12 mm Specimen size: 146 x 76 x 76 mm Specimen weight: 828 g This is a truly awesome ferrocolumbite specimen. Sold to the Smithsonian Institute. Two large and lustrous ferrocolumbites sit in opposition atop a mass of albite, all within quartz. The crystals have nucleated on the albite, and have grown within the quartz, which has permitted growth of the sharp and lustrous crystals you see here. Two other well-formed but small crystals are present on the back of the specimen, along with the base section of what would have originally been another large crystal. Very fine-grained accessory garnet occurs within albite on the back of the specimen. This specimen was found early on in our specimen mining when a broken crystal (the one on the back of the specimen) was noticed in a mine face. Careful work exposed very small sections of one of the crystals you see on this specimen. Work over a period of two days was required to remove the specimen from the rock as specialised tools needed be used (and had to be sourced from the nearest major town) to ensure no further damaged to the specimen occurred. We will post photos of the extraction soon. Once out of the ground, further preparation resulted in the specimen you see here. A simply Exquisite piece for the serious collector

87. Twinning, Polymorphism, Polytypism, Pseudomorphism Polytypism has little geologic consequence, and will thus not be substituting for Zr in the crystals structure Unlike crystalline minerals that show sharp, well http://www.tulane.edu/~sanelson/eens211/twinning.htm

EENS 211 Earth Materials Tulane University Prof. Stephen A. Nelson Twinning, Polymorphism, Polytypism, Pseudomorphism Twinning in Crystals Sometimes during the growth of a crystal, or if the crystal is subjected to stress or temperature/pressure conditions different from those under which it originally formed, two or more intergrown crystals are formed in a symmetrical fashion. These symmetrical intergrowths of crystals are called twinned crystals. Twinning is important to recognize, because when it occurs, it is often one of the most diagnostic features enabling identification of the mineral. What happens is that lattice points in one crystal are shared as lattice points in another crystal adding apparent symmetry to the crystal pairs. Twinning, because it adds symmetry, never occurs in relation to the existing symmetry of the crystal. Symmetry Operations that Define Twinning Because symmetry is added to a crystal by twinning, twining can be defined by the symmetry operations that are involved. These include: Reflection across a mirror plane. The added mirror plane would then be called a

(Here are just a few samples from our collection) Gold, 15 cm across, Harper Brothers mine, Tuoloumne County, California. The miners who rushed to California in 1849 gradually worked their way from the alluvial gold placers of the lowlands to the quartz veins of the Mother Lode in the foothills of the Sierras. Mines in this region have produced the majority of the world's fine gold specimens. This large leaf of gold was collected in the late 1800's and acquired by the museum in the late 1970's. It was loosely embedded in the rock of the vein, and had to be taken out and cleaned, but it is natural in its shape and appearance. Rhodochrosite, 10 cm, Huallapon mine, Pasto Bueno, Peru. Rhodochrosite is manganese carbonate, and shares an atomic pattern, or crystal structure, with carbonates of calcium (calcite), magnesium (magnesite), iron (siderite), zinc (smithsonite), and several other elements. These minerals are known as rhombohedral carbonates. Large crystals of rhodochrosite are rare; they are found in low-temperature, silver-bearing hydrothermal veins associated with granitic rocks in mountain regions. The two most productive deposits have been the Huallapon vein, which produced this crystal about 1976 (when the museum acquired it through the generous support of Mrs. David Craven), and the Sweet Home mine in Alma, Colorado, which has been mined for the last several years just for rhodochrosite mineral specimens.

Home Texas Geology and Minerals The Llano Uplift The oldest rocks exposed in Texas formed over a billion years ago when thick sequences of sediment were deposited in an ancient sea that bordered the North American craton. Approximately one billion years ago, the southern edge of this craton collided with another continent or an oceanic plate in an tectonic event that metamorphosed the sediments into gneisses and schists and partially melted more deeply buried rocks producing granitic magmas. The metamorphic and igneous rocks produced in this orogeny, the Packsaddle Schist, Lost Creek and Valley Spring Gneisses, Town Mountain and finer-grained granites, are now exposed in the Llano Uplift in central Texas. The ultramafic rocks and serpentinites that make up the Coal Creek igneous complex are though to represent the remnants of the island arc that collided with the North American craton. Terlingua , Texas is the site of one of the world's largest mercury deposits. At one time this mine produced approximately one forth of the mercury used in the United States. The mercury ore, cinnabar, occurs as powdery red veins in the layered limestones and volcanic lavas and tuffs in Brewster County. Liquid mercury also occurs in Terlingua. Industrial use of mercury declined when it became known just how toxic mercury was, and mining ceased at Terlingua in the 1970's.

Minerals Minerology: Mineral: "A homogeneous, naturally occurring, solid inorganic crystalline substance with a specific chemical composition." There are two types of solid: Glass: If we take a liquid and chill it so quickly that its molecules are frozen as they stand, without any microscopic organization, the result is a glass. Crystal: A solid that forms from a liquid or gas slowly enough that its ions pack together with a regular geometry. This is a crystal lattice. The geometric regularity with which anions and cations arrange themselves in a lattice is reflected on a macroscopic scale in the geometry of the crystal faces of the growing crystal grain. When do crystals form Solidification from melt (freezing): When a liquid is cooled below its melting point. Precipitation from a solution: When more of a substance is present in a solution than the solution can hold. Solid-state diffusion: can cause ions to reorganize themselves into new minerals without melting having occurred when a solid is heated or compressed. Cation substitution: Anions of a given atomic mass tend to occupy a larger volume than cations of similar mass. As a result, the geometry of a crystal lattice is largely determined by the packing arrangement of anions. Different cations often substitute for one another in the lattice.

VOLCANIC ROCKS Rocks are aggregates of minerals. Geologists divide rocks into three groups: igneous, metamorphic, and sedimentary. Igneous rocks crystallize from magma. Metamorphic rocks form by the deformation and/or recrystallization of pre-existing rock by changes in temperature, pressure, and/or chemistry. Sedimentary rocks form by weathering and erosion of preexisting rock to make sediment, which is lithified into rock. Most rocks in Hawaii are igneous. If magma solidifies within the crust, the rock is called an intrusive igneous rock. Intrusive igneous rocks have been exposed by erosion along rift zones of some of the older volcanoes in Hawaii. Intrusive rocks help to built the volcanoes from the inside. This photo shows the Uwekahuna laccolith that is exposed in the wall of Kilauea caldera. A laccolith is a pocket of magma that became trapped in the rocks layers before it reached the surface. Laccoliths have flat bottoms and convex tops. Photo by Steve Mattox, July 1990.

The Club The Show Newsletter Archaeology ... Email LAPIDARY ARTICLES Color of Crystals Sawing Gemstones A Visit to the Mineral and Lapidary Museum of Henderson County, NC The Color of Crystals Idiochromatic: Some minerals are nearly always the same color because certain light-absorbing atoms are an essential part of their crystal structure. These minerals are described as idiochromatic. For example, copper minerals are nearly always red, green or blue according to the nature of the copper present.: Allochromatic: A large number of minerals occur in a wide range of colors caused by impurities or light-absorbing defects in the atomic structure. For example, quartz, diamond, beryl, and corundum can be red, green, yellow, and blue. These minerals are described as allochromatic. Play of colors: The color os some minerals is really a play of colors like that seen in an oil slick or a soap bubble. This may be produced when the light is affected by the physical structure of the crystals, such as twinning or cleavage planes, or by the development duirng growth of thin films. Microscopic "intergrowths" of plate-like inclusions also interfere with the light.
