dc.description.abstractMelt-bearing polymict breccia, similar to so called “crater suevite” described from Ries, has been documented from other small to medium size impact craters and those formed in mixed targets. This breccia type typically forms a volumetrically significant portion of allochthonous impactites; however, their mechanism(s) of formation is still debated, with recent studies calling on fuel-coolant interaction to explain certain characteristics. Detailed petrographic studies of these and related impactites can help to shed light on their genesis. In this study we describe a 127 m thick, remarkably uniform deposit of polymict breccia containing co-genetic impact melt clasts from the Steen River impact structure (SRIS) in NW Alberta, Canada.
