Reinterpretation of the Ordovician rotations in NW Argentina and Northern Chile: A consequence of the Precordillera collision?
(Springer, 2011-04)
Early Paleozoic paleomagnetic data from NW Argentina and Northern Chile have shown large systematic rotations within two domains: one composed of the Western Puna that yields very large (up to 80°) counter-clockwise ...
Late cenozoic tectonics and paleomagnetism of North Cauca Basin intrusions, Colombian Andes: Dual rotation modes
(ELSEVIER SCIENCE BV, 1996-09-15)
Further paleomagnetic results are reported from 18 sites in Late Tertiary hypabyssal igneous rocks adjacent to the Romeral fault system which forms the eastern boundary of the North Cauca Basin. The paleomagnetic directions ...
Block rotations within the northern Peruvian Altiplano
(IRD ÉditionsFRA, 2008)
Counterclockwise tectonic rotations in the northern central Andes and clockwise rotations in the southern Central Andes have been systematically reported (see Roperch et al. 2006 and Arriagada et al., 2006 for a recent ...
Paleomagnetic data from the Precordillera of northern Chile: A multiphase rotation history related to a multiphase deformational history
(Elsevier Science, 2020-09-20)
One of the most conspicuous features of the Andean chain is the change in its trajectory from NW-SE to N-S at 18°S known as the Bolivian Orocline. Although the Central Andes rotation pattern (CARP) agrees roughly with the ...
Strength and failure modes of rock mass models with non-persistent joints
(PERGAMON-ELSEVIER SCIENCE LTD, 2007)
Most problems faced by the practicing rock engineer involve the evaluation of rock mass strength and deformability. The theoretical evaluation of the mechanical properties of fractured rock masses has no satisfactory answer ...
Paleomagnetic data and K-Ar ages from Mesozoic units of the Santa Marta massif: A preliminary interpretation for block rotation and translations
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
We report 6 K-Ar ages and paleomagnetic data from 28 sites collected in Jurassic, Lower Cretaceous and Paleocene rocks of the Santa Marta massif, to test previous hypothesis of rotations and translations of this massif, ...
New paleomagnetic data from Upper Oligocene–Lower Miocene rocks of the Northern Argentine Puna–Southern Bolivian Altiplano: Constraining the age of vertical axis rotations
(Elsevier, 2014-04)
Along the Central Andes a pattern of vertical axis rotations has been paleomagnetically identified. Such rotations are counterclockwise north of Arica Deflection (∼19° S) and clockwise to the south. Different hypothesis ...
Construction of perfect space-time codes
(2013-04-29)
In this work, we propose an innovative methodology to extend the construction of minimum and non-minimum delay perfect codes as a subset of cyclic division algebras over ℚ(ζ3), where the signal constellations are isomorphic ...
