The Geochemistry of the Holderness Tills and some others

Conclusions –

By shuffling the Excel files I could only find two significantly different Till samples both high in calcium. There were the Calcithorpe Till (sample WLW3) and one from Sherringham (sample SHER609). The Calcithorpe Till is thought to be locally derived from the Lincolnshire Wolds and the Sherringham sample was pale and was collected about a metre above a Chalk exposure.

It could be simply that the Tills (Boulder Clays or Diamicts) are simply a heterogeneous mixture rocks, sand, clay and silt and thus cannot be expected to have geochemical signatures.

The data is published here so that it is available for you to use and interpret. Do feel free to send me your suggestions!

There would need to be more research to test this out.

Suggestions -

Rather than crudely use “whole rock” the silt and clay fractions could be separated out for geochemical analyses and compared with the whole rock.

To test if the tills are too heterogeneous five (or so) samples could be collected about a metre apart at the same exposure and analysed.

Samples of the Tills could be collected less randomly from the Withernsea, Skipsea and Basement Tills, plus the clays on top of the Basement Till. The Bisat Research Group of the Hull Geological Society hopes to identify more detailed stratigraphy within the Withernsea and Skipsea Tills.
