Quaternary evolution of the Golo river alluvial plain (NE Corsica, France)

چکیده
The Golo River drains a steep catchment (average gradient of 30 m km?1, surface 1214 km2) in the northeast part Corsica Island, delivering sediments to Ligurian Sea. In this study, we review and revise geologic map constrain extent coastal alluvial plain formations their relative absolute chronology. To update each formation, performed geomorphologic analysis with DEMs satellite imagery data coupled an extensive pedogenic sedimentary field observations database, including new borehole 117,4 depth. Additionally, in-situ cosmogenic 10Be from depth-profile well-preserved terrace Fy2, yielding minimum age 70 ka for its emplacement. Our chronology, based on soil chronosequences, implies older ages than those previously obtained luminescence methods. Soil mixing by bioturbation is proposed as possibility explain differences between ages. scenario, dates original deposition terrace, while later development. We highlighted at least five outcropping terraces plain, which are controlled sea-level fluctuations were most likely deposited during past highstands (close present-day sea-level). Moreover, identified more 117 coarse fluvial that do not outcrop surface. New 26Al/10Be burial suggest unit results thick accumulation material filling zone significantly affected subsidence, probably accommodated normal fault Early Quaternary.

Alluvial fan facies of the Qazvin Plain: paleoclimate and tectonic implications during Quaternary
The present research focuses on a detailed facies description and interpretation of five alluvial fans of the Qazvin Plain. Beside the tectonic activity that leads to the localization of the fans on the northern margin of the Qazvin Plain, the climate has a significant role in the occurrence of their facies. The alluvial fans are divided into three facies groups: group 1, group 2, and group 3. ...

To the Editor: As members of the French Ministry of Health Working Group on autochthonous urinary schistosomiasis, we read with interest the 2 recently published articles regarding schistosomiasis screening of travelers to Corsica, France (1,2). Surprisingly, the authors of both articles lacked evidence to support the diagnosis of schistosomiasis in most of what they referred to as confirmed ca...
