Location, Age, and Rock Type of Volcanic Rocks Younger Than 5 Million Years in Arizona and New Mexico

摘要

As part of the assessment of the Hot Dry Rock geothermal energy potential of Arizona and New Mexico, a compilation of the locations and ages of volcanic rocks less than 5 Myr was made. The locations of those rocks less than 3 Myr are shown on a map of the region. Because the compiled information has many uses in addition to geothermal exploration, the entire compilation is presented as a tabulation. The table is organized first by state and secondly by latitude and longitude within each state. Rock type, age and error, method of dating, and original reference are also given. The K-Ar dates have not been recalculated using the most recent decay constants for exp 40 K. A few references gave only verbal descriptions of sample location; these locations were converted to approximate latitude and longitude. (ERA citation 06:023384)
