A Constrained 3D Density Model of the Upper Crust from Gravity Data Interpretation for Central Costa Rica
(2010-01-05)
The map of complete Bouguer anomaly of Costa Rica shows an elongated NW-SE trending gravity low in the central region. This gravity low coincides with the geographical region known as the Cordillera Volcánica Central. It ...

Thermal evolution of upper crustal magmatic systems from the Sierra de Velasco, NW Argentina
(Pergamon-Elsevier Science Ltd, 2019-01)
Detailed mapping of the Huaco intrusive Complex in NW Argentina documents a shift in the emplacement style of successive magma additions in an upper crustal environment as the system evolves thermally. The units of the ...
Genetic algorithm inversion of the average 1D crustal structure using local and regional earthquakes
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Knowing the best 1D model of the crustal and upper mantle structure is useful not only for routine hypocenter determination, but also for linearized joint inversions of hypocenters and 3D crustal structure, where a good ...
Microseismic reflection imaging of the Central Andean crust
(2016)
The coda of passive seismic recordings is often rich in arrivals that are coherent across several stations. If reflections can be extracted, then they may be used for seismic reflection subsurface imaging. With the objective ...
Does sheep selectivity along grazing paths negatively affect biological crusts and soil seed banks in arid shrublands? A case study in the Patagonian Monte, Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2011-08)
Domestic animals potentially affect the reproductive output of plants by direct removal of aboveground plant parts but also could alter the structure and fertility of the upper soil and the integrity of biological crusts ...
Structure and U-Pb dating of the Saint-Arnac pluton and the Ansignan charnockite (Agly Massif): a cross-section from the upper to the middle crust of the Variscan Eastern Pyrenees
(GEOLOGICAL SOC PUBL HOUSE, 2008-01)
In the Agly Massif (Pyrenees), two Variscan plutons, the Saint-Arnac pluton and the Ansignan
charnockite, intrude different levels of a c. 10 km thick crustal section. The Saint-Arnac pluton intrudes
through upper crustal ...
