Iron Formations as the Source of the West African Magnetic Crustal Anomaly

Autor: Nicolas Launay, Yoann Quesnel, Pierre Rochette, François Demory

Publikováno v: Frontiers in Earth Science, Vol 6 (2018)

The geological sources of major magnetic field anomalies are still poorly constrained, in terms of nature, geometry, and vertical position. A common feature of several anomalies is their spatial correlation with cratonic shields and, for the largest

International audience; We present a paleomagnetic study of the ~10 km diameter Karla impact structure in Russia. We sampled the target carbonate rocks, and a yet undocumented fragmental melt-bearing lithic breccia layer. This impact breccia, which c

International audience; Glassy ejecta are associatedto a limited number of impact craters, and yet hold key information about hypervelocity impact processes. Here we report on the discovery of a similar to 650 km(2) impact glass strewnfield in the Ce

International audience; Since the discovery of shatter cones (SCs) near the village of Agoudal (Morocco, Central High Atlas Mountains) in 2013, the absence of one or several associated circular structures led to speculation about the age of the impac
