Here we present the results of a new magnetostratigraphy for a middle Eocene
record of the South Pyrenean foreland basin in Spain. The new Lascuarre section
(ca. 650 m thick) provides new ages for fluvial (Capella Fm.), lacustrine (Escanilla
Limestone), and fluvial to alluvial (Escanilla Fm.) systems. We show that the
Capella Fm is of Lutetian age and the Escanilla Fm. is Bartonian. These results
fill a chronostratrigraphic gap in the sedimentary record of the Tremp-Graus-
Ainsa basin.
Integration of our Lascuarre chronology with other magnetostratigraphic studies
in the region allows for a complete snapshot of the entire source to sink system.
This new data permits a comprehensive study of the propagation of upstream
and downstream signals. Due to the quality of data, outcrops, and accessibility,
our new correlation profile opens the possibility to study the source-to-sink
expression of multiple drivers, and constitutes a, de facto, giant natural
laboratory.
An evaluation of the impact of the orbital cycles in the complete source-to-sink
system is also being carried out. If successful, we will have an enhanced
understanding of the mechanisms by which the climatic signals can be
transferred along the sediment routing systems, and a high-resolution
chronology.
