What are the 6 properties used to identify minerals a. Briefly describe how you would test a mineral for each of these properties a. Color The color of the mineral can help determine its identity.
In this lab activity you will become familiar with minerals and identifying their different properties. This lab will also introduce you to the deductive process where you will utilize the results of each property test to identify the name of the mineral from an established key. Mineral ID Kits for each station as listed below.

Now it is time to identify the mineral. Look at your Mineral Key. Find a mineral that has properties that match Sample A.
Type the name under Mineral name in the Gizmo and press Submit. It may take several guesses to get it right. What mineral is Sample A.
Get the Gizmo ready. Click Next so that Sample B is showing. Use a key to identify minerals.
The interactive 3-D models of the actual lab mineral samples were created using an ordinary camera and Agisoft Metashape Pro 3-D photogrammetry software. Using from 72 to 144 overlapping photos for each mineral specimen the software calculates the detailed topography of the mineral using stereographic techniques and then overlays that 3-D geometry with a composite photographic texture of the minerals.

Identification key for the minerals that you described above. To use a key to identify minerals you will be given a series of choices about the properties of a mineral. For most of the identification process the choices will be either this or that.
Compare your determinations of mineral properties with the mineral identification tables in the following pages. Lab 9 - Mineral Identification All rocks are composed of one or more minerals. In order to be able to identify rocks you have to know how to recognize those key minerals that make of the bulk of rocks.
By definition any substance is classified as a mineral if it meets all 5 of the criteria below. In this virtual investigation you will identify minerals by observing and testing their physical properties. After gathering data for an unknown mineral you will refer to an identification chart to determine the minerals identity.
Once the lab starts I give them the flowchart and the mineral kits to work with so they should be testing and identifying minerals simultaneously. Once the students have performed the tests on the mineral they use the flowchart to identify it and write down the mineral name in the Mineral ID. Each mineral has characteristic properties that can be used to identify it.
O Properties geologists use to help identify minerals are. O Color easy to observe but only a few minerals can be identified by color alone. Impurities can contaminate the mineral changing its color.
For example quartz can be white pink or purple. O Streak the color of a minerals powder. Use a steak plate to.
This Mineral Key is designed and intended for use on-line. The premise behind this Key is similar to that of the identification keys found in some fern and wildflower books. Key diagnostic properties are used to direct users to tables where further information on likely suspects is found.
