In the Makran area, a wide accretionary wedge is originated by north-dipping subduction of Neo-Tethyan oceanic lithosphere. The rear represented North Domain that consists an imbricate stack tectonic units derived from closure basin. This basin opened southward Eurasia continental margin during Early Cretaceous. Bajgan Complex interpreted as Paleozoic or older metamorphic basement representing ...

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...

The southern boundary of the Patos Shear Zone (PSZ) is characterized by mylonites resulting from deformation Paleoproterozoic basement gneisses, Neoproterozoic metavolcanic and metasedimentary rocks, granitic granodioritic intrusions. Among latter, Santa Terezinha Catingueira plutons show stretched shapes in agreement with shear zone’s regional trend. Recrystallized quartz grains these accommod...

During the Paleoproterozoic Era, Brazilian cratons experienced orogenic events that modified archean basement and sedimentary successions. In southern São Francisco Craton, it can be recognized evidence of an event happened between Rhyacian Orosirian periods. It is related to closure oceanic basin at this time, which led collision Archean Divinópolis Campo Belo metamorphic complexes. Graphite s...

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...

The Sassandra-Cavally (SASCA) domain (SW Côte d’Ivoire) marks the transition between Archaean Kenema-Man craton and Palaeoproterozoic (Rhyacian) Baoule-Mossi terranes. It is characterized by tectonic juxtaposition of granulite-facies amphibolite-facies rocks. Migmatitic grey gneisses, garnet-cordierite-sillimanite migmatitic paragneisses garnet-staurolite-bearing micaschists reached peak pressu...

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...

We present a new crustal cross section through the east-west trending ultrahigh-pressure (UHP) Dabie Shan orogenic belt, east central China, based on a 400km-long seismic refraction profile. Data from our profile reveal that the cratonal blocks north and south of the orogen are composed of 35-km-thick crust consisting of three layers (upper, middle, and lower crust) with average seismic velocit...
