pegmatites, 15 kimberlites, 16 basaltic moon rock, 17 breccia moon rock, 18 pristine moon rock, 19 KREEP moon rock
20 What is the big idea of this chapter?
21 List & describe the 3 types of magma.
22 What are the 4 main factors in the formation of magma?
23 Compare the melting points of basalt and granite.
24 What 3 minerals exhibit partial melting in molten rock?
25 Sketch figure 4, p. 114
they cool?
26 What are the 4 iron-rich minerals that form from magma?
27 What happens to the chemical composition of feldspars as
28 What do geologists hypothesize happens to newly formed crystals under certain conditions?
29 What are the last two minerals to crystalize out of magma? 30 What is classification of igneous rock based on?
