Abstract The Tethys Ocean was compartmentalized into the Mediterranean Sea and Indian during early Miocene, yet exact nature timing of this disconnection are not well understood. Here we present two new neodymium isotope records from isolated carbonate platforms on both sides closing seaway, Malta (outcrop sampling) Maldives (IODP Site U1468), to constrain evolution past water mass exchange between day via Mesopotamian Seaway. Combining these data with box modeling results indicates that...

High-resolution seismic imaging and coring in Lago Fagnano, located along a plate boundary Tierra del Fuego, have revealed dated sequence of Holocene mass-wasting events. These structures are interpreted as sediment mobilizations resulting from loading the slope-adjacent lake floor during mass-flow deposition. More than 19 deposits been identified, combining results 800 km gridded profiles used to site cores. Successions up 6-m thick deposits, pond atop basin spread eastward westward...
Two lacustrine sediment cores from Oldevatnet in western Norway have been studied order to produce a record of floods, mass-wasting events and glacier fluctuations during the last 7300 years. River density currents snow-avalanches deposited distinct ‘event layers’ at lake floor throughout this time interval. In study, novel approach has applied distinguish event layers continuous background sedimentation, using Rb/Sr-ratios X-Ray Fluorescence data. Grain-size distribution sedimentological...
Abstract Today, upwelling along the Oman margin in Arabian Sea is governed by South Asian Monsoon winds. The results formation of an oxygen minimum zone (OMZ) spanning across and large parts Indian Ocean. While these conditions are recorded as early middle Miocene (~15 Ma), long‐term dynamics yet poorly constrained during to late Miocene. Here, we use organic inorganic proxies combined with sedimentary paleontological records constrain evolution at Ocean Drilling Program Site 722B between...

Abstract In this paper we describe the stratigraphy and sediments deposited in Lake Samra that occupied Dead Sea basin between ∼ 135 75 ka. This information is combined with U/Th dating of primary aragonites order to estimate a relative lake-level curve serves as regional paleohydrological monitor. The lake stood at an elevation 340 m below mean sea level (MSL) during most last interglacial. relatively higher than average Holocene (∼ 400 ± 30 MSL). At 120 85 ka, rose 320 MSL while it dropped...
Abstract Recent advances in the chronology and palaeoclimatic understanding of Antarctic ice core records point towards a larger heterogeneity latitudinal climate fluctuations than previously thought. Thus, realistic palaeoclimate reconstructions rely development tight array well‐constrained with dense coverage. Climatic from southernmost South America are critical cornerstones to link these archives their American counterparts. At 54° S on Island Tierra del Fuego, Lago Fagnano is located...
Laminated lake sediments from the Dead Sea basin provide high-resolution records of climatic variability in eastern Mediterranean region, which is especially sensitive to changing conditions. In this study, we aim on detailed reconstruction fluctuations and related changes frequency flood dust deposition events at ca. 3300 2800 cal. yr BP sediment basin. A 4-m-thick, mostly varved section western margin (DSEn – Ein Gedi profile) was analysed correlated new International Continental...
Abstract. The new sediment record from the deep Dead Sea basin (ICDP core 5017-1) provides a unique archive for hydroclimatic variability in Levant. Here, we present high-resolution facies analysis and elemental composition by micro-X-ray fluorescence (µXRF) scanning of 5017-1 to trace lake levels responses regional hydroclimatology during time interval ca. 117 75 ka, i.e. transition between last interglacial onset glaciation. We distinguished six major micro-facies types interpreted these...
A 220-ka-long M w ≥ 7.0 earthquake record reveals an unexpectedly high seismicity rate on a slow-slipping plate boundary.
Abstract We have studied the history of earthquakes over past 70 kyr by analyzing disturbed sedimentary layers around margins Dead Sea. However, we know little about disturbances in basin depocenter, where water depth is ~300 m, and accessible only drilling. In this study, compare from Sea with contemporaneous earthquake record (~56–30 ka) that was recovered on western margin lake. This comparison allows us to discern characteristics disturbance different subaqueous environments identify...
