RE – OS AND PGE GEOCHEMISTRY OF ORGANIC-RICH SEDIMENTARY ROCKS AND PETROLEUM
… date with published basin histories and Ar-Ar geochronology demonstrate that Re–Os ages correspond with the timing of oil generation. Furthermore the similarities between oil and source rock 187Os/188Os at the time of oil generation (Osg) indicates that Osg can be used to identify oil source …

Prelude to the Tshirege caldera-forming eruption of the Bandelier magmatic system, New Mexico, USA
… compositions, phase equilibrium experiments, and ⁴⁰Ar/³⁹Ar sanidine geochronology to identify changes in the eruption rate and crystal cargo of the inter-caldera Valle Toledo Member rhyolites. Following the Otowi caldera-forming eruption of fayalite-bearing rhyolite at 1605.4 ± 2.3 ka, …

Closure of the Neotethys Ocean in Anatolia : structural, petrologic and geochronologic insights from low-grade high-pressure metasediments, Afyon Zone
… For age determination, I employed 40Ar-39Ar geochronology on white mica in carpholite-bearing rocks. For thermobarometry, a multi-equilibrium approach was used based on quartz-chlorite-mica and quartz-chlorite-chloritoid associations formed at the expense of carpholite-bearing assemblages, …
