(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 ...

-
(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 ...
-
(Elsevier, 2017)This paper addresses the problem of quantifying the joint uncertainty in the grades of elements of interest (iron, silica, manganese, phosphorus and alumina), loss on ignition, granulometry and rock types in an iron ore ...
-
(SOUTH AFRICAN INST MINING METALLURGY, 2008-05)Plurigaussian simulation allows constructing lithofacies or rock type models that reproduce the contacts between facies in accordance with the geologist's interpretation. its implementation requires inferring the local ...
-
(Elsevier, 2016)A better characterization of complex rock masses is essential in geotechnical engineering, as the empirical systems widely used for this purpose have significant limitations and do not provide adequate answers for risk ...
-
(ELSEVIER SCIENCE BV, 2013-05)Cross-well seismic reflection data, acquired from a carbonate aquifer at Port Mayaca test site near the eastern boundary of Lake Okeechobee in Martin County, Florida, are used to delineate flow units in the region intercepted ...
-
(Elsevier, 2020)Identification and categorization of geological, geotechnical, or geometallurgical domains is a common practice in the modeling of mineral deposits, in order to account for the controls exerted by categorical variables ...
-
(Earthquake Engineering Research Institute, 2017)The 2015 Illapel earthquake sequence in Central Chile, occurred along the subduction zone interface in a known seismic gap, with moment magnitudes of M-w 8.3, M-w 7.1, and M-w 7.6. The Main event triggered tsunami waves ...
