Geochronological, structural, and sedimentological data provide the basis for a regional synthesis of the evolution of the Cordilleran retroarc thrust belt and foreland basin system in the western In this region, the Cordilleran orogenic belt became tectonically consolidated during Late Jurassic time (∼155 Ma) with the closure of marginal oceanic basins and accretion of fringing .
· Container lines blast IMO for 'stalling' on fuel research. The momentum in tackling shipping emissions that came out of the COP26 climate talks in Glasgow had slowed by the time the IMO's 77th Marine and Environment Protection Committee wrapped up this week. PIL pulls back from brink of bankruptcy.

Mexico is loed within the socalled Fire Belt which makes it susceptible to earthquakes. In fact, twothirds of the Mexican territory have a significant seismic risk. On the other hand, the country's loion in the tropical zone makes it susceptible to hurricanes which are generated in both the Pacific and Atlantic Oceans.
This study reports new geochemical and radiogenic isotope data on hynormative Pleistocene to recent (<40,000 years) andesitic to dacitic volcanic rocks from Sierra de Chichinautzin (SCN), loed south of Mexico City, in the central part of the Mexican Volcanic Belt (MVB). Their rareearth element, Nb, Zr, and Y concentrations are generally lower than in mafic rocks from this area, which have ...
· Califas Tacos brings mobile taste of Mexico. On the corner of Sixth Street and Main in the Valero parking lot, Mexican street food has stopped in Belton and the locals are very pleased. With their own hashtag on Facebook, Juan Ceballos brings Californiastyle Mexican food to Texas. For years, Ceballos had aspirations of moving to Texas and ...
AbstractIn theory, the EW loion and high elevation of the Neovolcanic Belt have reduced floristic flow between parts of northern and southern Mexico. However, this barrier effect is not complete, as may be inferred from the distribution of moss taxa in adjacent areas. Migration across the Neovolcanic Belt may account for the presence of many moss species on either side of this mountain range.
· Epigenetic, NS, NNESSW quartz veins crosscut metapelites and metagabbro in Maru area. The objectives of this work were to study field, mineralogy, and geochemical characteristics of gold bearing quartz veins and soils. Euhedral and polygonal magnetite with hematite constituted the major ore minerals. Quartz occurred as main gangue phase with appreciable sericite and chlorite. The .
· Alpine vegetation is one of the most restricted ecosystems in Mexico. Its greatest extent occurs on the high peaks of the TransMexican Volcanic Belt (TMVB). In this study we document fern diversity of the alpine vegetation of central Mexico, generate a floristic list, provide a key for determination, and report the elevational limits of the species present. The latter information will serve ...
All journals published by a predatory publisher are potentially predatory unless stated otherwise. Original list. Go to update. This is an archived version of the Beall's list – a list of potential predatory publishers created by a librarian ...
BMC, research in progress. A pioneer of open access publishing, BMC has an evolving portfolio of high quality peerreviewed journals including broad interest titles such as BMC Biology and BMC Medicine, specialist journals such as Malaria Journal and Microbiome, and the BMC Series. Expanding beyond biomedicine into the physical sciences ...
· Transportation events are the most common cause of offshore fatalities in the oil and gas industry, of which helicopter accidents comprise the majority. Little is known about injury distributions in civilian helicopter crashes, and knowledge of injury distributions could focus research and recommendations for enhanced injury prevention and postcrash survival.
Belt and Road Economics: Opportunities and Risks of Transport Corridors. The six overland corridors of the Silk Road Economic Belt and the 21st Century Maritime Silk Road could improve transportation and connect many countries. China proposed the Belt and Road Initiative (BRI) in 2013 to improve connectivity and cooperation on a ...
Trans‐Mexican Volcanic Belt. Methods. Using nuclear and chloroplast DNA sequence data for 370 individuals, we investigate the genetic differentiation of 35 populations across the species range. We conducted phylogenetic, ...
· Shortening in the Sierra Madre Oriental foldthrust belt (east central Mexico) is localized along the margins of Cretaceous carbonate platforms and controlled by mechanical stratigraphy. The platform margins are deformed by imbrie series of thrust ramps, whereas the coeval basins and platform interiors are deformed by mapscale detachment folds.
· By Iker Reyes Godelmann. On 1 January 1994, the Zapatista Army of National Liberation (EZLN), an indigenous armed organisation, declared war on the Mexican Government, demanding "work, land, housing, food, health, eduion, independence, liberty, democracy, justice and peace."1 This article explains the factors that encouraged this indigenous uprising .
