Incomplete K/T boundary transition (Relleu 4). The K/T hardground contains abundant ferromanganese, cherty nodules, marking a hiatus from Maastrichtian to Oligocene (relleu-3)

Spectacular flutecasts, at the base of an Oligocene channel filled with a 10m thick channelized mass-flow.

Around Relleu, there are several outcrops of the K/T boundary. Only two adjacent outcrops along the CV229 are complete biostratigraphically.  

Locations of Relleu 1 and 2 sections (see ten Kate, W. G. H. Z., and Sprenger, A., 1993, Orbital cyclicities above and below the Cretaceous/Paleogene boundary at Zumaya (N Spain), Agost and Relleu (SE Spain): Sedimentary Geology, v. 87, p. 69-101.)
