This is an individual homework activity on rocks and minerals. Each student must produce a one-page research
report on an assigned rock. Your rock report must describe the chemistry and mineralogy of your rock and its
included minerals, and explain where and how the rock forms. But this part is very important:You must
underline and define any words or terms you use that are not part of the vocabulary learned in this class. If
we’ve used a term in this class then you don’t need to define it. For example, it is OK to simply say that granite
has a felsic composition, because you have learned the term felsic in this class. It is not OK to say that granite
may have a rapakivi texture with large round orthoclase crystals because your readings haven’t included the
terms “rapakivi” or “orthoclase”. If you need to use these terms you must define them in your own words.
