Front-end loaders extract sand and gravel (aggregate) from a pit and haul it to a feeder, which releases the aggregate onto a conveyor belt that is connected to a stockpile; the material is subsequently distributed to a processing plant. As mining progresses, the mining frontier moves farther away from the feeder, increasing loader cycle time. In turn, plant managers add loaders to maintain pro...

Ichniotherium tracks with a relatively short pedal digit V (digit length ratio V/IV < 0.6) form the majority of yet described Late Carboniferous to Early Permian diadectomorph tracks and can be related to a certain diadectid clade with corresponding phalangeal reduction that includes Diadectes and its close relatives. Here we document the variation of digit proportions and trackway parameters i...

—Topographically low exposures of Upper Triassic Chinle Group strata near St. Johns, Arizona, overlie the Middle Triassic Moenkopi Formation and can be assigned to four formation-rank units. These are, in ascending order, the Zuni Mountains (= “mottled strata”), Shinarump, Bluewater Creek (= “Mesa Redondo”), and Petrified Forest formations. Petrified Forest Formation strata in the vicinity of S...

Defining the fracture network and active fluid pathways are fundamental to characterizing a fractured reservoir. With this goal, we chose Saint Pierre Bois quarry (Vosges Massif, France) as natural analogue for Permian-Stephanian cover (arkoses)/Hercynian basement (granite) transition that serve geothermal reservoirs, example at Rittershoffen, Landau Insheim, where plants exploit kind of reserv...

The paper presents a multi-method characterisation of the Roman quarry middle Lower Jurassic (Pliensbachian) limestone situated in village Podpeč, south Ljubljana, and examples placement stone products made from micritic, fine-grained, oolithic facies into known extent quarry. 23 m rock succession ancient was exposed at northern tip St. Ana Hill by archaeological trenching. Petrological, microp...

With globally more than 100,000 km2 impacted by surface mining at present, and with increasing demand for surface-mined products, land managers are challenged to address landscape degradation of decommissioned quarries, especially in urban areas. In this study, soil, microclimate, vegetation community data were collected from geomorphologically distinct locations (quarry floor, platform pond, q...
