Programs to compute magnetization to density ratio and the magnetization inclination from 3-D gravity and magnetic anomalies
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Vector field formulation based on the Poisson theorem allows an automatic determination of rock physical properties (magnetization to density ratio-MDR-and the magnetization inclination-MI) from combined processing of ...
Tectonic fabric revealed by AARM of the proterozoic mafic dike swarm in the Salvador city (Bahia state): Sao Francisco Craton, NE Brazil
(ELSEVIER SCIENCE BV, 2008)
Magnetic fabric and rock magnetism studies were performed on 25 unmetamorphosed mafic dikes of the Meso-Late Proterozoic (similar to 1.02 Ga) dike swarm from Salvador (Bahia State, NE Brazil). This area lies in the ...
Caracterización magnética y datación preliminar mediante paleointensidades relativas de sedimentos lacustres de la Formación Tajamar (Guachipas), Salta Argentina
(Universidad Nacional Autónoma de México, 2014-11)
This paper presents a detailed study of rock magnetism in lacustrine sediments from three sample sequences from the Pleistocene Tajamar Formation, exposed in an outcrop near the locality of Guachipas (25º31.0´S 65°30.5'W), ...
The Sanrafaelic remagnetization revisited: Magnetic properties and magnetofabrics of Cambrian-Ordovician carbonates of the Eastern Precordillera of San Juan, Argentina
(Pergamon-Elsevier Science Ltd, 2017-11)
Systematic rock-magnetic and magnetofabric studies were carried out on samples from twenty-three palaeomagnetic sites distributed on the La Laja, Zonda, La Flecha, La Silla and San Juan Formations, which constitute a thick ...
Linking Speleothem And Soil Magnetism In The Pau D'alho Cave (central South America)
(Amer Geophysical UnionWashington, 2016)
Rock-magnetic proxies of wind intensity and dust since 51,200 cal BP from lacustrine sediments of Laguna Potrok Aike, southeastern Patagonia
(Elsevier, 2014-12)
The sedimentary archive from Laguna Potrok Aike is the only continuous record reaching back to the last Glacial period in continental southeastern Patagonia. Located in the path of the Southern Hemisphere westerly winds ...
Magnetic polarity zonation within the El Teniente copper–molybdenum porphyry deposit, central Chile
(Springer, 2010)
El Teniente porphyry copper deposit, the world’s
greatest intrusion-related Cu–Mo ore body, is hosted within
basaltic–andesitic volcanic and gabbroic rocks (mafic complex).
This ore body is strongly affected by multiple ...
