(U-Th)/(He-Pb) DOUBLE DATING OF DETRITAL ZIRCONS

Geochronology and thermochronology on detrital material provides unique constraints on sedimentary provenance, depositional ages, and orogenic evolution of source terrains. In this paper we describe a method and case-studies of measurement of both U/Pb and (U-Th)/He ages on single crystals of zircon that improves the robustness of constraints in each of these areas by establishing both formatio...

Experimental Methods of Antiquities Dating

Archaeological researches have been started as an interdisciplinary approach in the field of cultural heritage sciences (especially archaeology as an original field) for more than half a century. It has gathered together the researchers of different fields of human sciences, basic sciences, engineering and art according to their interests in archaeological findings and curiosity in solving huma...

Dating divergence of Polystigma and other Sordariomycetes

Studies on the evolutionary history of ascomycetes in terms of time scale will help to understand historical patterns that shape their biodiversity. Until now most of dating studies of ascomycetes have focused on major events in fungal evolution but not on divergence events within smaller groups of fungi e.g. within Sordariomycetes. We used molecular dating to estimate the time of separation of...

Dating Business Cycle in Oil Exporting Countries

In this paper, we empirically investigate the relationship between oil price changes and output in a group of oil exporting countries. The dynamics of business cycles in Libya, Saudi Arabia, Nigeria, Kuwait, Venezuela and Qatar are modeled by alternative regime switching models. We show that the extension of uni-variate Markov Switching model in order to include oil revenue improves dating busi...
