The Rb-Sr whole-rock isochron, age 1636 ± 66 Ma of Mirgarani granite, is the one oldest granite dated in northwestern part Chhotanagpur Granite Gneiss Complex (CGGC). initial Sr ratio 0.715 0.012 (MSWD = 0.11), showing an S-type affinity. has intruded migmatite complex Dudhi Group and forms formation comparable to granites Bihar Mica Belt around Hazaribagh (1590 30 Ma). present studies have est...

The Paleocene-Eocene Thermal Maximum (PETM, ~56 Ma) was one of the major global deep-time hyperthermal events past. Studies shallow-marine PETM records are crucial to understand continental hydrological response current warming. This study presents first detailed documentation in Xigaze forearc basin located along northern active margin eastern Tethys Ocean, and illustrates associated environme...

Slowly accumulating pelagic clays are enriched in metals that were formerly seawater, including iron, an important micronutrient. Because the minimally remobilized oxygenated porewater, may be a potential archive for records of past marine micronutrient cycling. Here, we present record changes hydrogenous iron (Fe) isotopes since late Cretaceous derived from dated with osmium isotope chronostra...

Abstract Understanding the dynamics of greater Yellowstone region requires constraints on deformation spanning million year to decadal timescales, but intermediate-scale (Quaternary) records erosion and are lacking. The Upper Snake River drainage crosses from uplifting that encompasses Plateau into subsiding Plain provides an opportunity investigate a transect across trailing margin hotspot. He...

The Los Menucos Complex (North Patagonian Massif, Río Negro province, Argentina) has been long regarded as Late Triassic in age. A Dicynodontipus-dominated record is historically known from this complex and particularly the Puesto Tscherig locality. Here we report Vera site, where a new track-bearing horizon was discovered within 73-m-thick volcano-sedimentary succession. Footprints site are mo...

Abstract The wide spatial coverage of sand dunes in continental interiors makes the understanding their activity and accumulation history valuable for palaeoenvironmental reconstructions interpretation landscape evolution. Nevertheless, study aeolian development at million‐year timescale is hampered by complex interaction factors determining dune migration inherently self‐destructive nature chr...

Archaeological sites in northern Africa provide a rich record of increasing importance for the origins of modern human behaviour and for understanding human dispersal out of Africa. However, the timing and nature of Palaeolithic human behaviour and dispersal across north-western Africa (the Maghreb), and their relationship to local environmental conditions, remain poorly understood. The cave of...
