when was the last time crater lake volcano erupted Approximately 7,700 years ago. where is mount mazama? Oregon, United States describe in few words the geology of the mount? It is part of the Cascade Volcanic Arc that stretches from northern California to southern British Columbia. Mazama sits within a region of crustal extension marked by fault zones what are some of the potential hazards from it? Landslides could threaten visitors to the national park or researchers by creating tsunami-sized waves, also potentially damaging infrastructure surrounding the lake. are there any geothermal activities around it? Scientists from the United States Geological Survey think that sources for geothermal energy use exist at Mazama and Crater Lake. is the energy utilized for anything productive? UNANSWERABLE describe something about mazama ashes? It serves as a common geological marker. Mazama Ash had a minimum fallout area mention a few of the ash impact? It is the most widely distributed tephra layer from the late Quaternary in the United States and southwestern Canada. It forms orange colored deposits. how is mazama ash identified? By electron microprobe analysis, by the refractive index of the volcanic glass, and by neutron activation analysis and similar techniques. Radiocarbon dating of associated carbon-bearing material may also aid identification of the Mazama Ash.

Mazama Ash [SEP] Composition and identification
The Mazama ash includes plagioclase, hypersthene, magnetite, hornblende, clinopyroxene, and volcanic glass. It can be distinguished from other volcanic ash deposits, such as those from eruptions of Glacier Peak, Mount St. Helens and Mount Rainier, by the unique chemistry of those constituents. This can be determined by electron microprobe analysis, by the refractive index of the volcanic glass, and by neutron activation analysis and similar techniques. Radiocarbon dating of associated carbon-bearing material may also aid identification of the Mazama Ash.
