Article
The equivalent source technique is a powerful and widely used method for processing gravity and magnetic data. Nevertheless, its major drawback is the large computational cost in terms of processing time and computer memory. We present two techniques for reducing the computational cost of equivalent source processing: block-averaging source locatio...
Preprint
Full-text available
<<< This paper has been submitted for publication in Geophysical Journal International. A preprint version is available on EarthArXiv. >>> We present the gradient-boosted equivalent sources: a new methodology for interpolating very large datasets of gravity and magnetic observations even on modest personal computers, without the high computer memor...

Full-text available
We present a new strategy for defining the location of point sources when applying the equivalent sources technique (EQL) for interpolating gravity and magnetic data. It consist in reducing the number of sources while keeping the same accuracy when compared with similar EQL methods. It also reduces the computation time and memory requirements, both...

Presented at EGU 2020 (online because of COVID-19), session "G4.3: Acquisition and processing of gravity and magnetic field data and their integrative interpretation". Details some of the work we've been doing in Verde and Harmonica for machine-learning style interpolation with equivalent-sources. In particular, applying state-of-the-art cross-vali...
Article
Full-text available
Scientific software is usually created to acquire, analyze, model, and visualize data. As such,many software libraries include sample datasets in their distributions for use in documentation,tests, benchmarks, and workshops. A common approach is to include smaller datasets in the GitHub repository directly and package them with the source and binar...
Preprint
We present a new methodology to compute the gravitational fields generated by tesseroids (spherical prisms) whose density varies with depth according to an arbitrary continuous function. It approximates the gravitational fields through the Gauss-Legendre Quadrature along with two discretization algorithms that automatically control its accuracy by...

Poster
Abstract submitted to LAPIS 2019: Inverse methods in Geophysics. We introduce a novel methodology for gravity forward modeling in spherical coordinates using tesseroids (spherical prisms) with variable densities in depth. It builds on previous work by the authors and introduces a new density-based discretization algorithm to ensure the accuracy of...
Chapter
In the last years, several works have characterized and discussed the crustal structure over the Southern Central and Patagonian Andes and adjacent foreland region by using geological and geophysical tools (Bassin et al., 2000; Bastow et al., 2008; Meijde et al., 2013; Park et al., 2008; Tassara, 2005; Tassara et al., 2007; Sacek and Ussami, 2009)....
Article
Full-text available
The Auca Mahuida volcanic field lies on the southernmost Payenia Volcanic Province, one of the broadest retroarc volcanic plateaux in the southern Central Andes (~38°S). This voluminous basaltic flooding of Quaternary age was originated from a deep asthenospheric source, interpreted as a mantle plume product of changing slab dynamics. The geometry...
Article
Global studies have assessed the importance of elastic thickness (Te) on orogenic evolution, showing that the style and nature of upper crustal shortening are influenced by the inherited lithospheric strength. Thus, pioneer works have identified that the upper crustal deformation style in the easternmost sector of the Central Andes in South America...
Chapter
The first geothermal gradient map in the Pampean flat-slab segment of the south-Central Andes and the transitional zones to normal subduction (toward the north and south) is presented in this contribution. The new data is correlated basin-basal heat flow BHF estimated from petroleum exploration borehole data, Curie point depths (CPD) derived from a...

Satellite gravimetry has proven to be a useful tool to identify mass anomalies along a subduction interface, interpreted as heterogeneities related to the rupture process during megathrust earthquakes. In the last years, different works, reinforced with data derived from satellite gravity missions as GRACE and now GOCE, have analyzed not only the s...

Conference Paper
Resumen Estudios a escala global han observado una relación entre el valor del espesor elástico (Te), la mecánica de deformación orogénica y el tipo de faja plegada y corrida resultante. En los Andes, cambios en la mecánica de deformación y tipo de faja plegada se han observado en las Sierras Subandinas y el Sistema de Santa Bárbara. La primera, po...
