Sandstone from the Staric site stratigraphically belongs to the Upper Carboniferous Petrkovice Member (Ostrava Formation, Mississippian, Early
Namurian) of the Czech part of the Upper Silesian Coal Basin (Hylova et al., 2013, 2016).
While engaged in the taxonomic revision of upper
Namurian to middle Westphalian floras of the Maritime Provinces of Canada, it became apparent that certain forms of the sphenopsid fossil-genera Annularia and Asterophyllites needed special attention in a broader context.
The carboniferous Westphalian and
Namurian contains numerous sandstones which are proven reservoirs in the oilfields within the Gainsborough Trough.
The Cliffs consist mainly of beds of
Namurian shale and sandstone, with the oldest rocks being found at the bottom.
The 10-furlong fillies' maiden is a tricky contest with a hopeful vote going to
Namurian Sunset.
In June 2011, Eden Energy commissioned US consultants RPS Group to investigate the potential shale gas reserves in the
Namurian measures of about 800sq km beneath Wales.
The company said it planned to take samples of the Westphalian coals and
Namurian Strata to enable laboratory testing to find out if methane can be used as a clean energy supply.
Metropator pusillus Handlirsch 1906 is of Early Pennsylvanian age (
Namurian Stage) and originates from the Altamont Coal Mine of the Lower Pottsville Group in central Pennsylvania.
The stratigraphical position of the oldest known Pterygota (Insecta, Carboniferous,
Namurian).
Electric logs indicate the well intersected gas bearing
Namurian Millstone Grit Formation (Carboniferous) at 10029ft and indications of formation gas are seen from mudlogs down to 11440ft.
However, Cross and Taggart (2004) assigned a tentative age of
Namurian to the Michigan Formation based on a study of fossil plant fragments and associated spores from the MNSC mine.
