concentrations of elements (as, co, cu, ni, mo, pb, v, cd, cr and zn) are studied in the surface sediments of bakhtegan lake, northwest of nyriz city, iran, to assess metal contamination. the average abundance order of trace elements content in bakhtegan lake sediments is cr>ni> v> zn> cu> co> as> pb> mo>cd. the comparison of trace elements concentration in bakhtegan lake sediments with toxicol...

The southeastern extension of the Tibetan Plateau (SETP) is distributed by typical longitudinal mountains and has unique climate characteristics significant regional differences. diurnal cycles rainfall amount, frequency, intensity over SETP in warm seasons (May–September) were investigated using high-density hourly station data possible mechanisms discussed analysing ERA5 reanalysis satellite ...

X-ray computed tomography (CT) is a promising tool that yields data useful for understanding the fine-scale density structure of partly lithified and tectonically deformed sediments. We conducted 21 CT scans of ODP Leg 131 sediments, including whole-round cores and thin-section chips, obtained from the toe of the Nankai accretionary prism. The samples range from highly deformed pieces from the ...

Abstract The intrusion of igneous sills into organic-rich sediments accompanies the emplacement provinces, continental rifting, and sedimented seafloor spreading. Heat from intruding in these settings alters sedimentary organic carbon, releasing methane other gasses. Recent studies hypothesize that carbon released by this mechanism impacts global climate, particularly during large province empl...
