(Springer, 2020)A weighted compressed sensing (WCS) algorithm is proposed for the problem of channelizetl facies reconstruction from pixel-based measurements. This strategy integrates information from: (i) image structure in a transform ...
-
(MDPI AG, 2018)This paper proposes a geostatistical approach for geological modelling and for validating an interpreted geological model, by identifying the areas of an ore deposit with a high probability of being misinterpreted, based ...
-
(Oxford University Press and Royal Astronomical Society, 2013)We present ultraviolet, optical and near-infrared observations of the interacting transient SN 2009ip, covering the period from the start of the outburst in 2012 October until the end of the 2012 observing season. The ...
-
(Springer Netherlands, 2018)The Atacama Desert, the driest of its kind on Earth, hosts a number of unique geological and geochemical features that make it unlike any other environment on the planet. Considering its location on the western border of ...
-
(Elsevier, 2020)The Valle Fertil-La Huerta batholith is a differentially tilted, compositionally stacked, calc-alkaline plutonic sequence in the central Famatinian arc of Argentina. It consists of two major lithologic units: these are (1) ...
-
(ELSEVIER, 2010)The flotation rate constant was modelled as a function of air dispersion properties and the complete feed particle size distribution by using the collision–attachment–detachment approach and introducing a parameter (U) ...
-
(2006)The use of edge based refinement in general, and Delaunay terminal edge refinement in particular are well established for adaptive meshing, but largely on a heuristic basis. In this paper, we present some theoretical results ...
-
(Elsevier, 2017)In this study, a new and efficient computational approach based on isogeometric analysis (IGA) and refined plate theory (RPT) is proposed for the geometrically nonlinear analysis of functionally graded (FG) microplates. ...
-
(Elsevier, 2015)The structure of the Chilean Frontal Cordillera, located over the Central Andes flat-slab subduction segment (27 degrees-28.5 degrees S), is characterized by a thick-skinned deformation, affecting both the pre-rift basement ...
-
(Elsevier B.V., 2019)The late Mesozoic-Cenozoic evolution of the Central Andes of northern Chile consists of a series of events related to changing conditions along the plate margin, leading to different episodes of compression and extension. ...
-
(Blackwell Publishing Ltd, 2019)Broadband seismic data were recorded on the ground surface around an exceptionally regular eruptive system, geyser El Jefe, in the El Tatio geyser field, Chile. We identify two stages in the eruption, recharge and discharge, ...
-
(ELSEVIER, 2010)We study the existence of positive radially symmetric solutions to a class of nonlinear elliptic problems involving extremal operators and nonlinearity of exponential or polynomial type. According to the values of a ...
-
(Elsevier, 2015)Based on high-resolution bathymetry and geophysical observations, the precise continental wedge geometry along the Chileanmargin is analyzed. The data showcomplex patterns in continentalwedge geometry that challenge the ...
-
(Copernicus Gesellschaft MBH, 2015)This paper discusses an integrated approach that provides new ideas about the structural geometry of the NNE-striking, Cretaceous Chañarcillo Basin located along the eastern Coastal Cordillera in the western Central ...

(Sociedad Geológica de Chile, 2020)
-
(Wiley, 2020)There exists a need to advance our understanding of debris-covered glacier surfaces over relatively short timescales due to rapid, climatically induced areal expansion of debris cover at the global scale, and the impact ...
-
(Elsevier, 2017)Understanding the evolution of a volcanic edifice is important in establishing its associated geological hazards. Apacheta and Aguilucho volcanoes, northern Chile, formed a volcanic complex with known fumaroles and geo-thermal ...
-
(Seismological Soc Amer, 2018)The Chilean Seismological Network has been rapidly growing in recent years, going from a few dozens stations working before 2010 to nearly a 100 installed all over the territory. Even more, nearly 300 strong-motion stations ...
-
(Elsevier B.V., 2019)Many studies have recently shown the potential of geophysical tools in bridging the information gap between individual point-scale measurements. Here, we upscale and extend the point-scale layering information from pedons ...
-
Geostatistical estimation of mineral resources with soft geological boundaries: a comparative study (SOUTH AFRICAN INST MINING METALLURGY, 2006-08)Mineral resource evaluation requires defining geological domains that differentiate the types of mineralogy, alteration and lithology. Usual practice is to consider the domain boundaries as hard, i.e. data from across the ...
