Correlation and biostratigraphy of the Kortrijk (Sint-Antonius) and Kortrijk (Lust) boreholes (early Silurian, Belgium)

Carnets de Géologie, 2005
Since their drilling, respectively in 1961 and 1971, the 83W421 Kortrijk (Sint-Antonius) and 83W44 Kortrijk (Lust brewery) boreholes have been studied rather extensively for biostratigraphical information.

Biostratigraphic correlation of the western and eastern margins of the Labrador–Baffin Seaway and implications for the regional geology. Fig. 5 [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2016
New analyses of the palynological assemblages in 13 offshore wells on the Canadian margin and six on the West Greenland Margin, in conjunction with onshore data, have led to a new biostratigraphic framework for the Cretaceous–Cenozoic strata of the ...
