Talk:Thorold Formation

Thorold Formation?
Revised Stratigraphy and Correlations of the Niagaran Provincial Series (Medina, Clinton, and Lockport Groups) in the Type Area of Western New York, by Carlton E. Brett, et al, refers to it as the "Thorold Sandstone." It does note that it was previously as "Thorold Quartzite" by Grabau (1913). Where do you have it as a formation. I will adjust if appropriate.
