Analysis of natural remanent magnetization directions obtained from 109 oriented samples taken at 4 sites, shows that some samples recorded a magnetic component different from the normal present geomagnetic field (GMF). The characteristic remanent magnetization (ChRM) was determined by progressive AF demagnetization. The analysis shows that the sections recorded ChRM of normal, intermediate and reverse polarities during the Pleistocene-Holocene transition and Holocene. Normal directions were recorded in QC, while normal and intermediate polarity directions at Mu and, reverse VGPs at ET. QC and the upper portion of Mu correspond to the paleosecular variation Holocene record for Ecuador during the &#8764;&#8804;4.7 ka BP. On the other hand, the lower portion of Mu logs represents the transition from normal to intermediate directions occurring at &#8764;&#8805;5.6 ka BP. Sites from ET recorded two stable oblique reverse records with a large fluctuation far from the present GMF at &#8764;10.5 ka BP. The transitional virtual geomagnetic poles generally agree with those registered during the possible Pleistocene-Holocene excursion observed in other places of the planet. When plotted in a present world map, VGPs calculated from normal samples at QC are very well clustered in Northern North America, Greenland and Northern Europe; most VGP's calculated from Mu are situated between 30° and 60° northern latitude in Northern North America, Greenland, western Europe, Africa and North Pacific Ocean. Interestingly, the majority of the reverse directions from ET conforms a patch located in southern Africa, and a few ones are situated in central Africa, eastern Australia and Antarctica. An Ecuadorian paleopole was calculated with data resulting from QC and Mu. Also other paleopoles of the same age were processed from other North and South American sites. Remarkably they agree well, although they do not agree with the geographical pole showing &#8764;15o angular difference in relation to the rotation's axis of the Earth. Finally, is discussed the hypothesis of the global excursional state of the GMF during the last &#8764;11.0 ka BP and the potential use as dating tool the excursion dated at 10.5 ka BP.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Se reportan datos paleomagnéticos de tres secciones sedimentarias del noroeste de Sudamérica (Ecuador). Las direcciones del magnetismo remanente natural obtenido de 109 muestras orientadas tomadas en 4 sitios -ciudad de Quito (QC), Mullimica (Mu) y El Tingo (ET)- mostraron que algunas registraron un componente magnético diferente al campo geomagnético (CGM) normal actual. La magnetización característica fue determinada por desmagnetización progresiva de campos alternos. El análisis de las muestras mostró que las secciones registraron una magnetización remanente característica de polaridades normales, intermedias y reversas durante la transición Pleistoceno-Holoceno y Holoceno. En QC se registraron direcciones de polaridad normal, mientras que normal e intermedia en Mu y, polos geomagnéticos virtuales (VGPs) reversos en el ET. QC y la parte superior de Mu corresponden a la variación paleosecular del Holoceno en Ecuador durante los &#8764;&#8804;4,7 ka BP. Por otro lado, la parte inferior del registro de Mu representa la transición de direcciones normales a intermedias ocurridas a &#8805;&#8764;5,6 ka BP. En ET se observaron dos registros estables oblicuos reversos con una gran fluctuación lejana del campo geomagnético actual a los &#8764;10,5 ka BP. Los polos geomagnéticos virtuales (PGV) transicionales generalmente coinciden con los registrados durante la posible excursión acaecida durante la transición Pleistoceno-Holoceno observada en otros lugares del planeta. Cuando se los representa en un mapa del mundo actual, los PGV calculados a partir de las muestras normales de QC están muy bien agrupados en el norte de América del Norte, Groenlandia y el norte de Europa; la mayoría de los de Mu se sitúan entre 30° y 60° de latitud norte en América del Norte, Groenlandia, oeste de Europa, África y el norte del Océano Pacífico. La mayoría de las direcciones reversas de ET se agrupan en un parche ubicado en el sur de África, y unos pocos están situados en el centro de África, el este de Australia y la Antártida. Con los PGV resultantes de QC y Mu se calculó un paleopolo ecuatoriano; también fueron procesados otros paleopolos de la misma edad en sitios de Norte y Sud América. Cabe destacar que coinciden bien, aunque mostraron una diferencia angular &#8764;15° con respecto al eje de la rotación de la Tierra. Finalmente, se discute la hipótesis del estado excursional global del CGM durante los últimos &#8764;11,0 ka BP y el uso potencial como herramienta de datación de la excursión fechada en 10.5 ka BP.]]></p></abstract>
