Ž . A combination of ground penetrating radar GPR and seismic imaging has been performed in a gypsum quarry in western Europe. The objective was to localize main cracks and damaged areas inside some of the pillars, which presented indications of having reached stress limits. The GPR imaging was designed from classical profiles with GPR processes and a customized, PC-based image-processing softw...

In Britain, upland spider communities can be found west of the Tees–Exe line between 300–1300 m where the physical conditions are often harsh due to an extremely variable climate, steep unstable slopes and thin soils (Ratcliffe, 1977). These communities often contain species which are common at lower altitudes and are characterized by the dominance of the Linyphiidae (Downie et al., 1995). Spid...

The Neolithic menhir El Gustal is located on a karstificated Coniacian limestone. The original morphology of the monolith and the pit has been preserved, and fragments of limestone filled the hollow. This has made it possible to identify construction phases of the most elementary stone constructive typology. Firstly, the original position of the monolith in the quarry of origin has been determi...

Pumped storage hydropower (PSH) enables the temporary of energy, including from intermittent renewable sources, and provides answers to difficulties related mismatch between supply demand electrical energy over time. Implementing a PSH station requires two reservoirs at different elevations with large volumes water. The idea using old, flooded open-pit quarries as lower reservoir has recently e...

A unique site at the northern area of Patagonia (Neuquén, Argentina) reveals a terrestrial ecosystem preserved in a detail never reported before in a Late Cretaceous deposit. An extraordinary diversity and abundance of fossils was found concentrated in a 0.5 m horizon in the same quarry, including a new titanosaur sauropod, Futalognkosaurus dukei n.gen., n.sp, which is the most complete giant d...

What is a Neandertal? A Neandertal (Homo neanderthalensis or Homo sapiens neanderthalensis) is a kind of human that lived in Europe and Western Asia until around 30,000 years ago. The first Neandertal skeleton was found by quarry workers in 1856 in the Neander Valley in Germany. At first people thought the oddlooking skeleton was that of a diseased person or of a Cossack from the Napoleonic War...

Two multituberculate molars from the Kimmeridgian of the Langenberg Quarry near Goslar (Lower Saxony, Germany) represent the first Jurassic mammals from Germany. An upper M1 with cusp formula 5L/4B is characterized by strongly ornamented enamel and is assigned to Teutonodon langenbergensis gen. et sp. n. within the plagiaulacid line. A second specimen preserving two large and one small cusp is ...

The Crow Creek Member is one of several marl units recognized within the Upper Cretaceous Pierre Shale Formation of eastern South Dakota and northeastern Nebraska, but it is the only unit that contains shock-metamorphosed minerals. The shocked minerals represent impact ejecta from the 74-Ma Manson impact structure (MIS). This study was aimed at determining the bulk chemical compositions and ana...

Blasting complaints are consuming an increasing amount of time and resources. This worsening situation has spawned new methods for relaying the public’s concerns. The direct measurement of crack response to both long term environmental and blast vibration effects with the same sensor exemplifies one new approach, which can be helpful in the process of educating quarry neighbors about the large ...
