Basaltic andesite
Basaltic andesite is a finegrained igneous rock that is moderately low in silica and low in alkali metal is not separately defined in the QAPF classifiion, which is based on the relative percentages of quartz, alkali feldspar, plagioclase feldspar, and feldspathoids, but would fall in the basaltandesite field. This corresponds to rock in which feldspathoid makes up less than 10% ...

Andesite
Andesite : definition Andesite is a very common volcanic rock of light gray hue, with fluid microlitic texture, often with vesicles and gas bubbles. Andesite is mainly composed of microlites of zoned sodium plagioclases (oligoclase and/or andesine), biotite, hornblende and pyroxene (augite, hypersthene) disseminated in a scarce vitreous bottom.

What is the difference between diorite and andesite?
Answer (1 of 2): Andesite is a finegrained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly. Diorite is a coarsegrained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reac...

Andesite Facts
Andesite is an igneous rock that is usually light to dark gray in color. Weathering may cause the color to change to various shades of brown. It is typically found in lava flows produced by stratovolcanoes, which is a composite, conical volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash. The lava cools rapidly at the surface and are usually composed of small ...

Volcanology photoglossary: andesite / VolcanoDiscovery
· Andesite is an igneous, volcanic rock, of intermediate composition, containing between about 52 and 63 weight % silica (SiO2). Andesites contain crystals composed primarily of plagioclase feldspar and one or more of the minerals pyroxene (clinopyroxene and orthopyroxene) and lesser amounts of hornblende.
