<dim:field mdschema="dc" element="description" qualifier="abstract" lang="es">Se ha realizado un estudio paleomagnético en el límite entre el Atlas Medio&#xd;
Plegado y el Atlas Medio Tabular, en el entorno de los sinclinales de Skoura y&#xd;
Tighboula y el anticlinal de Boulemane. La finalidad de este trabajo es tratar de&#xd;
reconocer una remagnetización que afecte a los materiales sedimentarios de&#xd;
dicha área. Para ello se han realizado diferentes test de estabilidad: (i) dos test&#xd;
del pliegue, uno en el anticlinal de Boulemane muestreando cinco estaciones&#xd;
paleomagnéticas en calizas jurásicas, y otro en el sinclinal de Tighboula, con&#xd;
tres estaciones en capas rojas del Cretácico Inferior; (ii) un test del conglomerado&#xd;
en un nivel basal del Cretácico. Los resultados de dichos test indican que&#xd;
en capas rojas la componente característica es una remagnetización sinpliegue,&#xd;
mientras que la señal magnética en las calizas es débil y no permite aislar ninguna&#xd;
componente paleomagnética. La similitud en el comportamiento&#xd;
paleomagnético de las capas rojas (propiedades de la magnetización remanente&#xd;
natural, probable dirección NNW de la remagnetización, polaridad normal sistemática)&#xd;
con la observada en cuencas de similares características del Alto Atlas&#xd;
podrían indicar que ambas remagnetizaciones están relacionadas.</dim:field>
<dim:field mdschema="dc" element="description" qualifier="abstract" lang="en">A paleomagnetic study has been carried out in the boundary between&#xd;
the Folded Middle Atlas and the Tabular Middle Atlas, around Skoura and&#xd;
Tighboula synclines and Boulemane anticline. The goal of this work is to&#xd;
test the existence of a remagnetization affecting the sedimentary rocks&#xd;
in this area. For this purpose different stability tests were done: (i) two&#xd;
fold tests, one in the Boulemane anticline by studying five paleomagnetic&#xd;
sites located in Jurassic limestones, and the other in the Tighboula&#xd;
syncline in three sites from Cretaceous red-beds; (ii) a conglomerate test&#xd;
was done sampling a Cretaceous basal level and the overlying red-beds.&#xd;
The results of these tests show a synfolding remagnetization in the redbeds,&#xd;
whereas the magnetic signal of the limestones is too weak and it&#xd;
is not possible to isolate a magnetic component. Red-beds shows similar&#xd;
paleomagnetic properties than in other basins of the High Atlas (properties&#xd;
of the natural remanent magnetization, a probably NNW trend of the&#xd;
remagnetization and a systematic normal polarity), which could indicate&#xd;
a relationship between both.</dim:field>
