Fresh volcanic rock coated the island’s southwest face, and destroyed thousands of buildings, dozens of miles of road, and almost a thousand acres of farmland. It was the Canary Island’s most destructive eruption in half a millennium. Winding through this jet-black rock is a vast network ...
Our reconstructions show that, for fajãs with lagoons to be formed, several factors should converge: a) presence of high coastal cliffs, made up of composite volcanic sequences, capable of producing large landslides that supply sufficient mobile sediment to the shelf; b) presence of a shallow...
Assange has denied receiving the files from the Russian government or backing the Trump campaign, despite a growing body of evidence suggesting he received material directly from Russia's military intelligence agency and coordinated media strategy with Trump's son, Donald Trump Jr. Last month, the ...
(1) The newly discovered Baqing eclogite has eclogite-facies peak metamorphic mineral assemblage of Grt + Omp + Rt + Ph + Qz, and formed at metamorphic conditions of 25 ± 1 kbar/730 ± 60 °C. The Ep-amphibolite facies retrograde metamorphism formed at co...
Pleistocene volcanic rocks in the Mariana Forearc revealed by drilling at Site 781 Geophysical surveys of the Mariana forearc, in an area equidistant from the Mariana Trench and the active Mariana Island Arc, revealed a 40-m-deep graben about 13 km northwest of Conical Seamount, a serpentine ...
15b, the northern branch of the Paleo-Tethyan Ocean began to subduct southward beneath the Yidun arc terrane, as indicated by the eruption of arc volcanic rocks and the emplacement of coeval granitoids during this period in the region (Hou et al., 2004; Cao et al., 2016). Show abstract...
Diamond is compressed carbon created by vast amounts of pressure, and many diamonds that we see were driven up to the surface by volcanic activity, which destroyed the surrounding material. The rock found in Russia survived that journey. Further analysis that revealed carbonate and other materials...
