Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2021-11-23T00:00:00Z
The data are the results of mass spectrometer experiments to measure 40Ar/39Ar ages of groundmass and mineral separates from volcanic rocks in northern Harrat Rahat, Kingdom of Saudi Arabia. The data were collected using a MAP216 noble gas mass spectrometer at the USGS facility in Menlo Park, Calif. These data were collected as part of a collaborative study conducted by the U.S. Geological Survey and Saudi Geological survey to assess the volcanic and seismic hazards associated with the northern Harrat Rahat volcanic field.
