This data release includes 40Ar/39Ar data from the U.S. Geological Survey for samples from Old Mine Park Area, Trumbull, Connecticut. Mineral samples were collected by Robert Wintsch and Harold Moritz. Potassium-bearing mineral grains were separated from the bulk sample and analyzed by argon geochronology at the U.S. Geological Survey Bascom ARgon Dating (BARD) Laboratory in Reston, Virginia. The data provide age constraints on units in the relevant geologic mapping area.

This data release includes 40Ar/39Ar collected at the U.S. Geological Survey for samples from the Janub Metamorphic Complex in Southern Jordan. Rock samples were collected by Hind Ghanem of the University of Jordan. Muscovite-rich microcores were drilled from a polished thick section of a deformed granitoid and analyzed by argon geochronology at the U.S. Geological Survey Bascom ARgon Dating (BARD) Laboratory in Reston, Virginia. The 40Ar/39Ar data constrain the timing of formation of the foliation defined by muscovite.

This data release includes 40Ar/39Ar data from the U.S. Geological Survey for samples from the Gidami gold deposit in the Eastern Desert of Egypt. Rock samples were collected by Basem Zoheir--Benha University/University of Kiel. Potassium-bearing mineral grains were separated from the bulk sample and analyzed by argon geochronology at the U.S. Geological Survey Bascom ARgon Dating (BARD) Laboratory in Reston, Virginia. The data constrain the timing of gold mineralization in the Gidami gold deposit.
This data release includes electron microprobe and 40Ar/39Ar collected at the U.S. Geological Survey for samples from the Sukari gold deposit in the Eastern Desert of Egypt. Rock samples were collected by Basem Zoheir--Benha University/University of Kiel. Muscovite from a polished thick section of sericitized wall rock was analyzed by electron probe microanalysis at the U.S. Geological Survey, Reston Electron Microbeam Laboratory. An aliquot of muscovite from this sample was microsampled from the thick section and analyzed by argon geochronology at the U.S. Geological Survey Bascom ARgon Dating (BARD) Laboratory in Reston, Virginia. The 40Ar/39Ar data constrain the timing of gold mineralization in the Sukari gold...
