U.S. archaeologists are using obsidian flakes left from the carving of tools to answer many questions about early human beings. University of Washington and Smithsonian Institute archaeologists used X-ray fluorescence spectrometers to determine the origin of 131 flakes of obsidian, a volcanic glass, found at 18 sites on eight islands in the Kurils. The flakes were found with other artifacts and dated to 2,500 to 750 years ago. The Kuril Archipelago stretches nearly 800 miles between the...

Rhyolite is an igneous, volcanic (extrusive) rock, of felsic composition, with aphanitic to porphyritic texture. Mineral assembly is usually quartz, alkali feldspar and plagioclase (in a ratio > 1:2). Biotite and pyroxene are common accessory minerals. Rhyolite can be considered as the extrusive equivalent to the plutonic granite rock. Due to their high content of silica, rhyolite form highly viscous lavas. They can also occur as breccias or in volcanic necks and dikes. Like obsidian,...
