Future directions of luminescence dating of quartz

13-Jul-2019 15:27

Luminescence methods applied to quartz have a key role for this research theme.

In the last few years, André Sawakuchi has studied the natural variability of the optically stimulated luminescence (OSL) and thermoluminescence (TL) characteristics of quartz to understand the luminescence sensitization of quartz grains under the action of Earth surface processes.

He leads the Luminescence and Gamma Spectrometry Laboratory at IGc-USP and his main interest is the study of source-to-sink sedimentary systems and their response to climate changes.

Under this perspective, the reconstruction of Neogene and Quaternary landscapes shaped by large rivers in tropical South America is of particular interest.

His primary research interest lies in the development of a new rock-surface dating technique based on luminescence.

This involves measuring and modelling luminescence-depth profiles beneath the rock surfaces to decipher their depositional history.

He has the distinction of having attended all LED conferences since the 1987 one held in Cambridge. Sumiko Tsukamoto works at the Geochronology and Isotope Hydrology Section at Leibniz Institute of Applied Geophysics, Hannover, Germany and manages the Luminescence and ESR laboratories.

On the over-arching theme of point-defects in solids, he also collaborates with others to exploit the utility of allied methods such as positron annihilation and the like.His main research interest is the study of mechanisms of luminescence in materials using time-resolved optical stimulation for which he has developed instrumentation, theory and analytical methods.Dr Chithambo has used the technique to study quartz, feldspar and α-Al2O3: C addressing a wide range of questions including the influence of annealing, thermal history, and the link between sensitivity and luminescence lifetimes in quartz and also developing analytical methods for studying the influence of measurement temperature on lifetimes and luminescence throughput in α-Al2O3: C.Reza Sohbati is a postdoctoral researcher at the Nordic Laboratory for Luminescence Dating, Aarhus University, Risø, Denmark.

He completed his Ph D at Aarhus University and his MSc at Tehran University, Iran.Stratigraphic Correlation and Isopach Maps of Punjab Platform in Middle Indus Basin, Pakistan, Naseem Aadil and Ghulam Mohyuddin Sohail, #10364 (2011).

“My first Couchsurfing hookup happened when I was staying with my friend in Miami,” Riccardo recalls. Months later Riccardo got a phone call from the same girl, asking if she could stay at his place in New York City. “I never talked to her again,” he admits, adding, “I mean, we’re friends on Facebook.” Couchsurfing was born after a budget-conscious traveler named Casey Fenton sent out a mass request for accommodations in Iceland and received 50 invitations from students with a free spare futon.… continue reading »
