Geomorphological and stratigraphical significance of Pliocene red clay in Hungary
This paper deals with red clays in Hungary, which are younger than the Upper Pannonian (Upper Miocene) but older than the Pleistocene. Their origin and stratigraphical position is still debated. Based on geomorphological position and mineralogical

An exceptional stratigraphic and pedologic record of Pleistocene environmental conditions occurs at the Kieler Site in the Driftless area of southwestern Wisconsin. Peoria, Roxana, Loveland, and pre-Loveland loesses overlie weathered bedrock
This paper demonstrates a Mt. St. Helens provenance for the uppermost of the tephra and suggest correlations with the known eruption sequence. The AA. then discuss the geochronologic and stratigraphic significance of this discovery
This paper reports AMS C 14 ages of 10 bones and teeth of 3 species of large mammals from the Dutchess Quarry Caves, New York. Together with the Holocene conventional C 14 dates of charcoal and the varied stratigraphic proveniences of the fluted
Morphologic and stratigraphic evidence shows that a late-glacial ice cap existed on part of the Eastern Cordillera of Ecuador (Lat. 0°20'S) with a mean elevation of 4200 m where none exists now. The ice cap developed in response to a surface
