The Lycian Nappes contain slices of ophiolites and sedimentary rocks various ages that crop out in SW Turkey. They evolved were emplaced under the effect Late Cretaceous-Miocene compressional regime. Tavas Nappe is part contains Jurassic-Eocene sediments. Babadağ Formation, forming middle Nappe, composed limestone at base sized calciturbidites with chert intercalations upper part. Standard Micr...

The Taatsiin Gol Basin in Mongolia is a key area for understanding the evolution and dispersal of Central Asian mammal faunas during the Oligocene and early Miocene. After two decades of intense fieldwork, the area is extraordinarily well sampled and taxonomically well studied, yielding a large dataset of 19,042 specimens from 60 samples. The specimens represent 176 species-level and 99 genus-l...

Ornithischian dinosaur body fossils are extremely rare in Triassic rocks worldwide, and to date the majority of such fossils consist of isolated teeth. Revueltosaurus is the most common Upper Triassic ornithischian dinosaur and is known from Chinle Group strata in New Mexico and Arizona. Historically, all large (>1 cm tall) and many small ornithischian dinosaur teeth from the Chinle have been r...

During ODP Leg 155, color reflectance was routinely measured downhole at all but one site to determine light-reflectance levels in the wavelength band of visible light (400 to 700 nm) of the sediments recovered. Reflectance measurements taken on previous ODP legs have demonstrated that lithologic changes in carbonate-rich (>20%) pelagic and hemipelagic sediments can be characterized using these...

Cone penetration testing (CPT) is one of the most efficient and versatile methods currently available for geotechnical, lithostratigraphic and hydrogeological site characterization. Currently available methods for soil behaviour type classification (SBT) of CPT data however have severe limitations, often restricting their application to a local scale. For parameterization of regional groundwate...

The Vale do Forno archaeological sites (Alpiarça, central Portugal) document the earliest human occupation in the Lower Tejo River, well established in geomorphological and environmental terms, within the Middle Pleistocene. In a staircase of six fluvial terraces, the Palaeolithic sites were found on the T4 terrace (þ24 m, above river bed) which is made of a basal Lower Gravels unit (LG) and an...

[1] We report new drillstring packer permeability tests conducted during Integrated Ocean Drilling Program (IODP) Expedition 327 in upper oceanic basement in Hole U1362A on the eastern flank of the Juan de Fuca Ridge. Hole U1362A lies within a closely spaced array (40–2460 m separation) of six holes in well-sedimented 3.5–3.6 m.y. old crust that were drilled, tested, and instrumented with boreh...
