The palynology of the Plenmeller Coalfield and adjacent areas in Northern England

The samples collected in the present investigation from Featherstone, Plenmeller and adjacent areas in the North of England, yielded diverse, well preserved miospore assemblages with marked vertical variation, which compare fairly closely with those previously described from strata of the same age elsewhere. Six major Assemblages are recognised from coal and shale samples collected within Namurian and Westphalian A and B strata which have not previously been dated by miospore evidence. Oetailed comparisons are made with miospore assemblages previously described by several authors from similar stratigraphical horizons in Scotland, North England and. the Central Province. Formal taxonomic description is presented for 206 species belonging to 71 genera.tions 22 new types are described and one new combination is suggested.
