The model of geological evolution an interarc basin, which is the north-east ending Mid Kuril trough located on continental slope Kuril-Kamchatka trench, was constructed. Seismic facies analysis first applied to define sedimentation conditions in a deep water trench. based 2D CDP reflection seismic data obtained by Dalmorneftegeophysica JSC 2014. According modeling results, basin began form Lat...

We have deduced the steady-state lithospheric geotherm at c. 1 Ga in the south Indian shield area using the available data on the concentration of radioactive elements, and the f-T conditions of Proterozoic mantle xenoliths in the south Indian kimberlites as constraints. The geotherm was adjusted back to 2.5 Ga by keeping the surface temperature constant and calculating the temperature change a...

Facies models are used to better capture heterogeneity in mineral deposits and petroleum reservoirs. Facies are often considered as mutually exclusive and exhaustive at the scale of the geological model. These two assumptions are needed for sequential indicator simulation and most other facies modeling techniques; however, the assumption that an entire grid block consists of one facies type bec...

Introduction and General Characteristics: The fan-shaped deposits of the Tharsis Montes generally share three major facies: 1) Ridged facies, 2) Knobby facies, and 3) Smooth facies. The ridged facies consists of narrow, parallel, concentric ridges interspersed in places with small hills [1]. The hummocky or knobby facies consists of dense concentrations of small sub-km scale circular to irregul...

Abstract – The design of an information fusion system is a complex task. This study tries to help in the choice of the relevant input data and in the system adjustment. Such a study relates to a notion referred to in the literature as “Elucidative Fusion System” (EFS). The proposed method is based on information theory tools which provide a means to measure the impact of each input attribute on...

Litho-facies classification is an essential task in characterizing the complex reservoirs petroleum exploration and subsequent field development. The lithofacies at borehole locations detailed but lacks providing larger coverage areas. acquired 3D seismic data provides global for studying reservoir facies heterogeneities study area. This applies six supervised machine learning techniques (Rando...

Introduction: Over the past several years, we have presented new data and proposed a cold-based glacial hypothesis for the Tharsis Montes fan-shaped deposits [14], which were first identified and analyzed using Viking data [5-8]. Based on stratigraphic relationships with young lava flows in Tharsis, we know that the deposits are of midto late-Amazonian age [8,9], but we have little information ...

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...

296 A wellfield (Boise Hydrogeophysical Research Site or BHRS) is being developed in Boise, Idaho, for hydrologic and geophysical research in a shallow, coarse (cobble-and-sand), alluvial aquifer. Our goal is to develop cost-effective methods for quantitatively characterizing the distribution of permeability in heterogeneous alluvial aquifers using hydrologic and geophysical techniques. Respons...

This paper compares the predictive performance of different geostatistical kriging algorithms for intertidal surface sediment facies mapping using grain size data. Indicator kriging, which maps facies types from conditional probabilities of predefined facies types, is first considered. In the second approach, grain size fractions are first predicted using cokriging and the facies types are then...
