... the term Honduras Group. The Agua Fría Formation is left as an independent stratigraphic element. The unnamed siliciclastic member is herein named “the Tepemechín Formation” after a river south of Lake Yojoa. Although thicknesses as great as 1200m have been reported for the Agua Fría Formation...

... Early Cretaceous clastic sedimentation of the Zicapa Formation on the Guerrero-Morelos Platform (southern Mexico) and the Tepemechin Formation of the Central Chortís terrane (Honduras). The units accumulated in fault-bounded basins associated with left-lateral slip. The basins developed in the Central...
