The following deductions can be made concerning the red clay in core 94138-104: 1) the coloration suggests a Carboniferous redbed source, the most proximal being the Deer Lake Basin; 2) foraminifera analysis indicates reduced salinity; 3) the position of the red unit at the top of the glaciomarine sequence shows that it was deposited immediately following deglaciation but before the deposition of Unit 3; and 4) the lack of clasts (dropstones) suggests a non-glacial source.
