Potassium or Plagioclase Feldspar: The feldspar minerals may have the same color and luster as some calcite varieties, but they can be easily distinguished on the basis of their hardness. Unlike calcite, feldspar minerals are harder than glass and cannot be easily scratched by a nail.
Mar 13, 2018· A piece of quartz can scratch a sample of calcite, but calcite cannot scratch quartz. If you have a sample if each, try to scratch one sample with the other to observe the difference in the hardness. You also can test the hardness of these two minerals using a pocketknife. The blade of the knife has a hardness value between calcite and quartz.

by segregation of minerals into different layers. In most gneisses, equi-dimensional mineral grains of quartz and feldspar are more abundant than the platy micas. Non-foliated metamorphic rocks include marble, quartzite, and hornfels (a fine-grained, hard rock). Some of the lab manuals in lab have more complete descriptions of metamorphic rocks.

Remember that glass can be almost any color, including black, so don't be fooled by the color. Also, a dark piece of glass may appear to be opaque if …
During this lab activity students will use their knowledge of the physical properties of minerals to investigate and describe seven common minerals including quartz, feldspar, biotite mica, calcite, pyrite, graphite, and talc. Students will determine hardness, color, luster, streak color, and cleavage using various hands-on testing methods.
Nov 10, 2011· Calcite vs Quartz Calcite and quartz are highly abundant minerals on the earth surface. Both are present in all three types of rocks named as sedimentary, igneous and metamorphic rocks. Although they are highly available, they are valuable due to their significant differences in color, shape, properties, etc. Calcite Calcite is a mineral, which […]
Calcite Biotite Feldspar Quartz Hematite Pyrite Galena Magnetite Procedure: 1. Pass one sample at a time to the students. 2. What is the mineral's luster? Does it look like metal? Then it has a metallic luster. 3. What is the mineral's hardness? If the mineral will scratch a glass plate or if it is difficult to scratch it with a nail, then ...

Re-examine the hand-samples for quartz, plagioclase, and microcline. Then examine hand-samples SANDSTONE A, SANDSTONE B, and SANDSTONE C. ...
Each mineral on the scale can only scratch another mineral lower on the scale (Table 1). For example, calcite can scratch a fingernail or a sample of gypsum or talc. In addition, a copper penny, a steel nail, or a sample of apatite can scratch calcite. Some minerals may …

WHAT TO DO IN THIS LAB In Part 1, you will learn the fundamental physical properties used in identification of minerals: luster, hardness, cleavage, streak, and density. In Part 2, you will examine the most common rock forming minerals and describe the properties which allow you to recognize them. In Part 3 you will use your observations and the mineral identification tables in Pellant and ...
common rock-forming minerals Mineral Definition: naturally-occurring, inorganic solid with an ordered atomic arrangement and well-defined chemical composition Simplified Classification of Mineral Lab Samples
This mineral identification kit has everything you need to get groups of students started identifying minerals! It contains 150 mineral samples, a 68-page illustrated lab manual, and a mineral testing kit. There are five samples each of copper, graphite, fluorite, chalcedony, magnetite, and 25 other kinds of minerals.

Lab 1 - Physical Properties of Minerals ... to name your unknown mineral sample. The major physical properties will be discussed briefly ... Some relatively common minerals, such as quartz and calcite, may exist in any color. Variations in color of a given mineral is known as mineral varieties. If we take quartz as an example:
Mineral ID Self-Instruction Lab Name _____ Geology 100 – Harbor Section Your goal for this lab is to become familiar with the physical properties used to identify minerals. Physical properties are determined by the chemical and crystalline properties of the given mineral.
LUSTER - The way in which a mineral reflects light. Two general categories used to describe luster are metallic and nonmetallic. These samples have metallic luster and look like metals (gold, silver, copper etc.). They can be identified specifically by other physical properties. The color of their streak is a useful one. a pyrite _____
Lab Activity on Minerals B–37 Activity: 1. Obtain unlabeled samples of quartz, halite and calcite (Please do not bash the labeled samples in the boxes). 2.

IMPORTANT ROCK-FORMING MINERALS (or mineral identification for real life) ... you are not going to be finding museum-quality or even lab-quality samples of individual minerals lying around. Instead, there will be mineral grains within rocks, and in most cases you won't be able to pull them out for the types of ... quartz . potassium feldspar ...
Feldspar can be replaced by other minerals and mineral mixtures of similar physical properties. Minerals that could be used to replace feldspar include pyrophyllite, clays, talc, and feldspar-silica (quartz) mixtures. The abundance of feldspar will make these substitutions unnecessary for the foreseeable future.
Lab 2: Mineral Lab notes. Minerals are inorganic, solid, naturally occurring substances that have a characteristic chemical compositions, distinctive physical properties, and crystalline structures. Chemical composition is the chemical elements that make up any given mineral.For instance, the mineral quartz is silicon dioxide SiO 2; the mineral galena is an ore of lead, and its chemical ...
