Activity 5
Ultramafic rocks are very
dark to dark greenish in color,
and they are composed of
olivine, pyroxene, and
calcium-bearing plagioclase
feldspars (anorthite). They
melt in higher temperatures
(around 1200 C) and have
the lowest silica content
(around 40%).
Mafic rocks are dark in color,
and they are composed
mostly of pyroxene and
plagioclase feldspars (leaning
on the calcium-rich
plagioclase like bytownite and
labradorite), but there are
also traces of olivine and
amphiboles. Basaltic magmas
are usually less viscous and
fluid.
Felsic rocks are lightly colored (usually
pinkish or light orange), and they are
composed mostly of pot-assium feldspar,
mica, and quartz, with traces of
amphiboles, biotites, and plagioclase
feldspars. They melt in lower
temperatures (usually around 750 C)
and are usually viscous because of its
high silica content (around 70%).
Intermediate rocks are
grayish in color, and they
are composed mostly of
amphiboles, biotites, and
traces of pyroxenes.
Sodium-bearing
plagioclase feldspars, like
andesine, oligoclase, and
albite are also common.
