Mineral Lab Worksheet

Part 1: Recording Observations

In the following chart, record your observations of each test for the seven minerals. After you have completed all tests, name the minerals in Part 2 of this worksheet. An example of how to fill out the chart is illustrated follows.

|Recorded Observations for Minerals 1-7 |

|Tests |Example |Mineral 1 |

|Example: Fluorite |80% certain |I am almost certain this mineral is fluorite, but I am not completely sure. Fluorite and gypsum|

| | |are both white, shiny, have white streaks, cleave, and show no reaction to acid. However, the |

| | |specific gravity of this mineral is 3.18, which is higher than gypsum, so I am pretty sure it |

| | |is fluorite. |

|Mineral 1: Pyrite |80% certain |Main color was hard to determine but a combination of the streak test and a gravity of 5.10 |

| | |makes me believe this is correct. |

|Mineral 2: Talc |85% certain |Quite sure this mineral is talc. Green and white color makes this different and unique. |...
