Lesson 8 Homework | Mineral Identification Lab

Introduction: Minerals are the naturally occuring inorganic solid elements and mixtures from which rocks are made of.  We are going to use minerals physical properties  to help identify various minerals samples.  . Go to: http://profharwood.x10host.com/GEOL101/Labs/Minerals/index.htm  to complete the following lab.

Fill in each of the following tables based on the “virtual tests” you run on each unknown mineral sample that is listed in the cart.  You are only doing the five following samples 1, 3, 4, 10, 16

1

Mineral Sample 1: Click edit background and use the text function to insert answers into the mineral chart based on your findings from the virtual lab.

1

Mineral Sample 3: Click edit background and use the text function to insert answers into the mineral chart based on your findings from the virtual lab.

1

Mineral Sample 4: Click edit background and use the text function to insert answers into the mineral chart based on your findings from the virtual lab.

1

Mineral Sample 10: Click edit background and use the text function to insert answers into the mineral chart based on your findings from the virtual lab.

Both Sulfur and Galena are softer than glass. Using just the minerals, how can you determine which of the two minerals is harder.

1

Describe why Galena breaks along flat surfaces (cleavage) while Pyrite breaks along uneven surfaces (fracture)?

Using page 16 of the ESRT, what is the best physical property that could be used to identify the difference between Selenite Gypsum and Potassium Feldspar.
