Remains of hominoid primates collected by Yale Peabody Museum Geological Survey of Pakistan expeditions to the Siwalik Group rocks of the Potwar Plateau, Pakistan, are described. They consist of facial, gnathic, dental, and postcranial remains of Ramapithecus, Sivapithecus, and Gigantopithecus. They are discussed anatomically and without precise taxonomic attributions. The hominoids come from 2...

a r t i c l e i n f o The Upper Cretaceous John Henry Member of the Straight Cliffs Formation preserves regressive shoreface and channel facies, and transgressive lagoonal tidal inlet facies that suggest distinct modal sandstone compositions. Detrital modes from six sandstone facies (upper shoreface, lower shoreface, deflected mouth bars, fluvial channels, tidal inlets and washover fans), and t...

We present detailed bathymetry, remotely operated vehicle (ROV) and submersible observations, and sedimentary and radiocarbon age data from carbonate deposits recovered from two submerged terraces at 150 m (T1) and 230 m (T2) off Lanai, Hawaii. The tops of the terraces are veneered by relatively thin (b5 m) in situ accumulations of coralline algal nodule, coralgal nodule, Halimeda and a derived...

The problem of estimating the location of facies boundaries is difficult in history matching, partly because of the geological complexity. The truncated plurigaussian method for modeling geologic facies is useful in this aspect not only for the wide variety of textures and shapes that can be generated, but also because of the internal consistency of the stochastic model. This method has not bee...

In recent years, the occurrence of water and wind erosion indifferent parts of country due to the changes of land use from the forest andpasture into the agricultural and also construction of communication lineshave increased. The study and research on this phenomenon, the effectivefactors in creating them and also identification of geomorphology faciestypes are necessary to prevent the waste o...

Coal exploration and mining in extensively drilled and sampled coal seams can benefit from 3D statistical facies interpolation. Starting from closely spaced core descriptions, and using interpolation methods, a 3D optimum and robust facies distribution model was obtained for a thick, heterogeneous coal seam zone deposited in the non-marine As Pontes basin (Oligocene-Early Miocene, NW Spain). Se...

When CO2 is injected in saline aquifers, dissolution causes a local increase in brine density that can cause Rayleigh-Taylor-type gravitational instabilities. Depending on the Rayleigh number, density-driven flow may mix dissolved CO2 throughout the aquifer at fast advective time-scales through convective mixing. Heterogeneity can impact density-driven flow to different degrees. Zones with low ...

Modern marine seismic reflection data have allowed for the study of morphology submarine channels in a 3D perspective. This presents quantitative analysis continental slope channel complexes within Canterbury Basin (New Zealand). It aims to characterize and facies better understand their formative sedimentary processes, paleoenvironment, petroleum prospectivity. Submarine morphometric parameter...

Infraorbital morphology is often included in phylogenetic and functional analyses of Homo. The inclusion of distinct infraorbital configurations, such as the "canine fossa" in Homo sapiens or the "inflated" maxilla in Neandertals, is generally based on either descriptive or qualitative assessments of this morphology, or simple linear chord and subtense measurements. However, the complex curvili...
