Radiocarbon is the most widely used geochronological tool in the earth sciences for the late Quaternary the last 50,000 years. ❋ Unknown (2009)
“Likewise, radiochemists could be entrained into pseudo-scientific debate because of all the massive and magnificent geochronological data that have been gathered over the last few decades.” ❋ Unknown (2005)
He said the satellite will probe the physical characteristics of the lunar surface, certain aspects of physical, chemical and "geochronological aspects" of the moon. ❋ Unknown (2003)
If possible, we will date calcites reflecting important tectonic activity by means of U-Th and/or U-Pb dating techniques in order to determine a geochronological evolution of the changing stress fields and the absolute timing of important fault activities. ❋ Unknown (2003)
The geochronological framework of these deposits is based on ten radiocarbon dates. ❋ Unknown (2003)
Our own geochronological studies suggest the infill is nearly 2 million years old. ❋ Unknown (2000)
U-Pb (SHRIMP) and 40Ar/39Ar geochronological constraints on the evolution of the Xingxingxia shear zone, NW China: A Triassic segment of the Altyn Tagh fault system ❋ Unknown (2010)
Ancient plate motions are usually estimated from geological, geochronological and paleomagnetic data. ❋ Unknown (2010)
Their approach of analyzing high-resolution topographic data of closely-spaced fault scarps is promising especially when combined with subsurface data as well as geochronological and paleoseismic data, and it provides a basic scheme for analyzing scarp populations in a complex topographic region. ❋ Unknown (2010)
"For the first time we find lavas that have the high helium 3-to-helium 4 ratio, the right neodymium based on this discovery in 2005, and they plot on the geochron," Jackson says, referring to a geochronological dating scheme based on lead isotope ratios. ❋ Unknown (2010)
These new results, as well as previously published geochronological data, contradict the hypothesis that the clastic sediments of Stratigraphic Unit 6 (SU6) are in primary context with the faunal, archaeological and other materials found in SU6, and that all have ages consistent with the optically stimulated luminescence (OSL) estimates of 30-36 ka. ❋ Unknown (2010)
Using paleomagnetic and geochronological data from the drilled basalts, this project attempts to answer the question of whether the deep Hawaiian and Louisville mantle plumes, the two longest-lived primary hotspot systems in the Pacific, have moved in concert or independently. ❋ Unknown (2010)
University of NSW-based Dr Andy Herries worked with fellow geochronological experts in Melbourne and Cairns to establish the age of the ancient remains at 1.78 to 1.95 million years. ❋ Unknown (2010)
I am particularly impressed with the phylogeny plot view, which offers a chronological color coded map of many important geochronological timescale. ❋ Unknown (2010)
It will be accompanied by sets of geotagged photos, high-precision GPS data points, and a GIS database of published geochronological data, among other things. ❋ Unknown (2009)
Geological mapping and geochronological studies have shown much lower eruption rates for ocean island basalts (OIBs) in comparison with those of lavas from large igneous provinces (LIPs) such as oceanic plateaux and continental flood provinces. ❋ Unknown (2009)
