TL;DR: In this article, the effects of climatic factors (i.e. monthly mean temperature and total precipitation) on radial growth (earlywood width, latewood width and total ringwidth) and on latewood stable carbon isotope composition in a pedunculate oak (Quercus robur L.) stand in northeastern Hungary were analyzed.

TL;DR: In this article, high-resolution organic carbon isotope, calcareous nannofossil and elemental geochemical analyses from the black shale-bearing Lower Toarcian section in the Reka Valley, Hungary, with the aim of assessing any regional differences in the sedimentary and geochemical record and their bearing on the underlying oceanographic and climatic processes.

TL;DR: The Datangpo Formation manganese deposits (DFMnD) in South China formed during the interglacial stage between the Sturtian and Marinoan glaciations of the Cryogenian period as discussed by the authors.

TL;DR: Toarcian black shale that hosts Mn-carbonate microbialites at Urkut, Hungary was investigated by mineralogical, inorganic, and organic geochemical methods for characterization and comparison with other European black shales representative of the Toarcian Oceanic Anoxic Event.

TL;DR: The Urucum manganese deposit in Brazil is a ~600 Mt microbially-mediated sedimentary Mn ore with 27% Mn and 12% Fe as mentioned in this paper, and the lower Mn-1 is ferruginous, while the upper Mn-2 consists mainly of 30-75% braunite.
