This article argues that far from being a marginal Black Metal subgenre, Industrial Black Metal is central in bringing out Black Metal’s often disavowed appropriation of machinic noise and its critique of machine society. Through its... more
The Bastar Craton of India is composed of Archaean nuclei of tonalite–trondhjemite–granodiorite gneisses, enveloped by an older granite–greenstone belt (~3000 Ma) with banded iron formation (BIF), and an auriferous younger... more
The current theory of axial precession of the earth relative to the distant stars resulting in continuous precession of the equinoxes and the corresponding pole shift in a circle around the zodiac in a cycle of approximately 26000 years... more
El cambio climático, profundizado por el hombre está haciendo de nuestro planeta un lugar complejo e inestable para vivir, tanto para el hombre como para el resto de las especies que están sufriendo las alteraciones climáticas como de la... more
RESUMEN Se presentan los resultados de un análisis detallado de facies de la sucesión de diamictitas de la Formación Cancañiri en el área de Sella – Negro Muerto al norte de Tarija. La sección estudiada cubre sedimentos del Ordovícico... more
The uppermost portion of the Taciba Formation, Itararé Group, Paraná Basin, Brazil, records a succession of depositional environments tied to the demise of late Paleozoic glaciation. In the study area, Teixeira Soares county, state of... more
Türkiye’nin güneybatısında bulunan Batı Toroslar dağ kuşağında Kuvaterner buzullaşmalarının izlerini taşıyan dağlar vardır. Bu kuşakta yer alan dağlardan biri olan Dedegöl Dağı’nda (2992 m), Kuvaterner’in soğuk dönemlerinde buzullaşmalar... more
During the Quaternary, there were a series of environmental changes linked to cycles of glaciations on a global scale that profoundly affected and shaped the landscapes and life forms of our planet Earth. The major glaciation occurred 110... more
Recently NATURE published a discussion on construction of sills in attempt to prevent or slow melting glaciers that are discharging ice into the ice fjords. Several further papers promptly followed publication of this essentially... more
Climate changes have occurred several times throughout the Earth's history; however, current global warming episode may be occurring at a faster rate. Species may respond to this changes by adapting to the new conditions or by shifting... more
The Kola Peninsula and Russian Lapland (Murmansk Oblast, northwest Arctic Russia) represents a major sector of the Fennoscandian Ice Sheet (FIS) where empirical geomorphological, sedimentological, and chronological data are lacking and... more
Atmospheric CO 2 and global climate are closely coupled. Since 800 ka CO 2 concentrations have been up to 50% higher during interglacial compared to glacial periods. Because of its dependence on temperature, humidity, and erosion rates,... more
The quaternary period is the source of numerous studies for the diversity of scenarios that caused its climatic changes marked by glacial and interglacial cycles. Knowing the size of these changes and their forcing is essential to enable... more
Jörg Lang (1), Muayyad Al Hseinat (2), Christian Brandes (1), Andrea Hampel (1), Christian Hübscher (2), and Jutta Winsemann (1) (1) Leibniz Universität Hannover, Institut für Geologie, Hannover, Germany (lang@geowi.uni-hannover.de), (2)... more
Understanding the relationship between geological processes and landscape evolution is important in promoting and popularizing geology as a discipline, and in linking together the combined needs of geological and landscape conservation... more
Las glaciaciones cuaternarias han dejado registro en diversos espacios geográficos de la corteza terrestre. Esto no ha sido una excepción en los Andes Centrales de Argentina y Chile, donde enormes valles labrados por la erosión glacial y... more
Here we present initial 187Os/188Os (Osi) values integrated with δ13Corg for the first Paleozoic section — the Ordovician/Silurian boundary GSSP at Dob's Linn, Scotland. Our 187Os/188Os data tracks major changes in climate that occurred... more
Erosional surfaces within the late Ediacaran upper Kuibis and lower Schwarzrand Subgroups of the Nama Group, that extend from the Klein Karas Mountains in Namibia eastward to the Namibian-South African border and from southern Namibia to... more
Alice M. Doughty, Joerg M. Schaefer, Aaron E. Putnam, George H. Denton, Michael R. Kaplan, David J.A. Barrell, Bjørn G. Andersen, Samuel E. Kelley, Robert C. Finkel, and Roseanne Schwartz Here we address a long-standing puzzle of... more
This study characterizes precipitation and temperature variability for the whole region of Gilgit-Baltistan (GB), covering winter dominated high mountain region. Trend analyses of the historical data for the period 1955-2010 show that... more
Two cap carbonates overlying glaciogenic diamictites crop out extensively in the eastern Vaza Barris Domain of the Sergipano Belt, northeastern Brazil. They are represented by carbonates of the Jacoca Formation, resting on top of... more
The Lipalian or Vendian Period (600-541 million years ago) begins and ends with global environmental perturbations. It begins as the worst glaciation on record draws to a close. It ends with a sudden appearance of abundant skeletonized... more
The internal sedimentology of the Armoy moraine, which marks a late Devensian (Weichselian) incursion of Scottish ice into the north of Ireland, is described from a temporary exposure near Armoy village. The exposure (up to 30 m long,... more
Although global warming is not overlooked as an anthropogenic climate change, this book is focused on natural climate changes and their environmental and societal implications in the last ten thousand years. The motivation for this... more
The glacial morphology of southern South American presents invaluable evidence to reconstruct former glacier behaviour and its relation to climate and environmental changes. However, there are still spatial and temporal gaps in the... more
Antarctic climate changes have been reconstructed from ice and sediment cores and numerical models (which also predict future changes). Major ice sheets first appeared 34 million years ago (Ma) and fluctuated throughout the Oligocene,... more
We report the presence of Late Pleistocene piedmont glaciers represented by the largest hummocky moraine field observed in the Eastern Mediterranean. The piedmont glaciers originated from the Geyikdag ice cap (~40 km2), situated between... more
"A recent paper by Hall (2010) argues that Quaternary ice masses in the Lesotho–Drakensberg region produced no subglacial erosional imprints and were therefore cold based. This argument is based upon (1) the comparison with cold-based... more
Foreword: This paper was shortlisted in 2012 by the Royal Society of Chemistry as a contending hypothesis to explain the phenomenon known as the Mpemba Effect: whereby warm samples of water are sometimes observed to freeze more rapidly... more
