Family of Minerals

MINERALS
Lesson 3 - Page 4

PROCEDURE:

After you read the information on chemical families, use the "Chemical Family of Minerals" diagram and a periodic table to answer the questions.

CHEMICAL FAMILIES OF MINERALS

element	element + 0₂	element + S₂	element + S0₄	element + C0₃	element + BO₃	element + Si0₂	element + Halogens
native	oxide	sulfide	sulfate	carbonate	borate	silicate	halide
graphite copper sulfur	hematite magnetite limonite	galena pyrite sphalerite chalcopyrite bornite	gypsum	calcite dolomite azurite malachite	borax ulexite	quartz feldspar mica kyanite chrysocolla talc olivine hornblende	fluorite halite

List the 20 elements that are considered native minerals. Look at the periodic table and write down their symbol.

What are the elements the make up the following mineral families?

A. carbonate
B. sulfate
C. sulfide
D. silicate
E. oxide
F. borate

Fill in the chart below. Look at the previous lab for the formula. Write out the elements name. For example Calcite is CaCO_3,the chemical family is "carbonate" and the elements are calcium, carbon, and oxygen.
