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...

This contribution deals first new ICP-MS U–Pb zircon ages that indicate Middle- and Late Triassic magmatic episode tectonometamorphic events, respectively, for the central Patagonia region, instead of a Paleozoic history as previously estimated. The Calcatapul Formation consists (meta-) volcano-sedimentary syn-rift sequence deposited unconformably, shortly after extensional Gondwanide orogenic ...

Exploration of copper ore in the Nepal Himalayas has been carried out by different researchers at times. The author conducted detailed geological studies and mineral exploration some polymetallic prospects also reviewed literature related to Nepal. present research is able delineate two distinct mineralization belts extending from west east identify promising sites for that could be feasible mi...

Abstract IODP Expedition 357 drilled 17 shallow sites scattered over ~ 10 km in the west to east spreading direction across Atlantis Massif oceanic core complex (OCC, MAR, 30 ºN). Mantle exposed footwall of Atlantic OCC is nearly wholly serpentinized (80–100%) harzburgite and subordinate dunite. A recent whole-rock chemistry study by Whattam et al. (Chemical Geology 594. 10.1016/j.chemgeo.2021....

The Goiás Archean Block (GAB) in central Brazil is an important gold district that hosts several world-class orogenic deposits. A better comprehension of the crustal, tectono-magmatic, and metallogenic settings GAB essential to accurately define its geological evolution, evaluate crustal growth models, target We present overview systems, regional whole-rock Sm-Nd analyses have been used constra...

Major, minor, and trace element geochemistry as well iron oxidation state isotopes were investigated in serpentinites olivine-talc fels present along a metamorphic gradient the Bergell contact aureole (Central European Alps) to evaluate mobility during serpentine. This is an ideal target study dehydration of mantle rocks due increase temperature from greenschist facies conditions (350°C) amphib...

Using a combination of microstructural, spectroscopic, and geochemical analyses, we investigate how subgrain rotation recrystallization fluid migration affect Ti concentration [Ti] in naturally deformed quartz veins from the Prijakt Nappe (Austroalpine Unit, Eastern Alps). These coarse-grained veins, that formed at amphibolite facies conditions, were overprinted by lower greenschist deformation...
