Apophyllite, analcite, chabazite, prehnite and stilbite are described from pectolite-, chlorite-, calciteand quartz-bearing veins and joint coatings in the late Carboniferous quartz dolerite of the Whin Sill of the northern Pennines. These veins represent the final hydrothermal stages in the sill's emplacement and are not related to the widespread lead-zinc-barium-fluorite mineralization of the...

The genus Kassinella was established by Keller (1960: 90) for extinct Lower Carboniferous (Tournaisian) corals from Kazakhstan. The name, however, is preoccupied by the senior homonym Kassinella Borissiak (1956: 50) (Brachiopoda), equally honouring N. G. Kassin, famous geologist and explorer of Kazakhstan. To resolve the homonymy, in accordance with the International Code of Zoological Nomencla...

The facies distribution and palaeobotanical identity of fossil charcoal is described from the Upper Carboniferous (Westphalian A–B) Joggins section, Nova Scotia, in order to examine the fire ecology of early Westphalian floodplains. Three charcoal assemblages are noted. Assemblage (1) consists of channel sandstone bodies, containing beds of calcrete breccia, cordaite logs (up to 3 m long), and ...

A new archaeorthopterid Chenxiella liuae gen, et sp. nov. is described from the Upper Carboniferous (Namurian B-C) of the Tupo Formation in Ningxia Hui Autonomous Region (China). The new taxon exhibits a unique combination of wing venation characters. Together with other described archaeorthopterids, this new specimen further demonstrated considerable diversity of this group in Namurian ecosyst...

Lycophyte trees, up to 50 m in height, were the tallest in the Carboniferous coal swamp forests. The similarity in their shoot and root morphology led to the hypothesis that their rooting (stigmarian) systems were modified leafy shoot systems, distinct from the roots of all other plants. Each consists of a branching main axis covered on all sides by lateral structures in a phyllotactic arrangem...
