Rock Type: Volcanic (igneous). Minerals: Like basalt, andesite is rich in
plagioclase and pyroxene. But, since it mixed with melted mud, it has many more
minerals: quartz, biotite, and hornblende, for example. Color: Intermediate to
felsic (dark gray to light tan). Because andesite has more light-colored minerals (
like quartz and feldspar), it looks lighter than basalt. Grain Size: Fine-grained to
medium-grained. Andesite lava erupts from volcanoes and cools quickly, giving
its minerals little ...

Rocks of the Columbia River Basalt Group consist primarily of labradorite (
plagioclase feldspar), augite (pyroxene), and opaque metal oxides (commonly
titanomagnetite) in a matrix of volcanic glass and cryptocrystalline material. The
most common accessory minerals are apatite, olivine, and metallic sulfides.
These are present in varying and minor amounts as intergrown and isolated
crystals. The most abundant secondary minerals are a nontronitic smectite,
quartz, clinoptilolite, and ...

UNITED STATES The kyanite-group minerals occur in almost every large area of
metamorphic rocks in the United States (Espenshade and Potter, I960;
Espenshade, 1961, 1962, 1973). Members of this group have ... (Teague, 1950).
Kyanite-group minerals are also widely distributed in schists and gneisses in
Montana (Groff, 1963), Washington (Thorsen, 1966), Oregon (Espenshade, 1973

Little hydrologic information is available for the volcanic and intrusive rocks in the
Coast Range, but well information indicates that these rocks also have low
permeability (Frank, 1974; Frank and Collins, 1978). Coast Range volcanic rocks
commonly contain abundant secondary minerals (Keith and Staples, 1985) that
tend to reduce fracture permeability. Saline water is commonly encountered in
marine sedimentary rocks beneath and adjacent to the Willamette Lowland; this
saline ...

INTRODUCTION The California section of the Pacific Crest Trail (PCT) is noted
for its great diversity of plants and animals, minerals and rocks, climates and
landscapes. The Oregon section of the PCT provides quite a contrast, having the
most homogenous vegetation and land- scape of this tri-state route. The
Washington section falls between these two extremes. Along the route covered
by this volume, certain rocks, plants, and animals appear time and time again.
The most common ...

Granitic rocks are of deep-seated origin within the lithosphere and their presence
on the earth's surface is caused by erosion. Basaltic rocks, however, form from
lavas that spread from volcanoes on the earth's surface. Examples of such lavas
are the basaltic rocks of the states of Washington and Oregon, and of the
Hawaiian Islands. When magma cools it solidifies and its chemical constituents
crystallize as minerals. Granitic rocks contain an abundance of quartz and
feldspar and are ...
