To solve the problem of high sintering temperature of vitrified bond, a novel low- temperature vitrified bond based on Bi2O3-B2O3 glass system was proposed. The effect of nano-SiC and nano-ZrO2 on the phase composition, fluidity and mechanical proper

Reconciling the Snowball Earth hypothesis with sedimentological cyclicity has been a persistent challenge. A new cyclostratigraphic climate record for a Cryogenian banded iron formation in Australia provides evidence for orbital forcing of ice sheet

Abstract Sediments from the semi-enclosed Japan Sea are sensitive to paleoclimatic perturbations and they offer great opportunities for many regional and global paleoceanographic and paleoclimatic studies. These studies often require a robust chronol

Abstract The Quaternary hemipelagic sediments of the Japan Sea are characterized by centimeter- to decimeter-scale alternation of dark and light clay to silty clay, which are bio-siliceous and/or bio-calcareous to a various degree. Each of the dark a

North Africa is one of the most vulnerable regions on Earth to anthropogenically-driven climate change, but also one of the least equipped to deal with the consequences. Predictions of precipitation levels over the forthcoming centuries diverge, not

The Sahara is the largest hot desert on Earth. Yet the timing of its inception and its response to climatic forcing is debated, leading to uncertainty over the causes and consequences of regional aridity. Here we present detailed records of terrestri

Past hydroclimate change in Africa and the Arabian Peninsula plays a vital role in early human evolution and dispersal. Although arid today, North Africa and the Arabian Peninsula experienced periodic humid intervals, during which strengthened rainfa
