Ramblar Fmn, upper shale unit, Nogueras area, Aragon, Spain (Devonian of Spain)

Where: Aragon, Spain (41.1° N, 1.1° W: paleocoordinates 44.6° S, 34.1° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Ramblar Formation, Late/Upper Emsian (402.5 - 391.9 Ma)

• middle part of Upper Emsian.

• member-level stratigraphic resolution

Environment/lithology: marine; shale

• "The Ramblar Fmn is another excellent example for the structure of Celtiberian rhythmothems." [see lithology]
• "1)...the Ramblar Fmn begins with 18m of an arenaceous unit...calcareous sandstones...The facies development from these arenaceous beds of very shallow facies into the overlying limestones...2) 8m of largely carbonate sediments are the biogenic basis of the next rhythmothem...coquinites and crinoidal limestones...marly layers...3) 15m of rather black shales constitute the initial part of another Hercynic episode..."
