The Balderton Sand and Gravel: Pre‐Ipswichian cold stage fluvial deposits near Lincoln, England
Abstract The Balderton Terrace marks a former course of the River Trent between Newark and the Lincoln Gap. The principal deposit, the Balderton Sand and Gravel, is interpreted as a braided river sediment. Ice wedge casts truncated by intraformational erosion surfaces at many levels indicate syndepo...
