DOI: 10.1016/j.apsoil.2017.09.008
Abstract: Irregular, sub-metre scale occurrences of a highly unusual calcified peloidal (pelletal) limestone are described from a polygenetic paleosol from the sub-Arundian landsurface (Carboniferous, 343Ma) of South Wales. The pedogenic origin is supported by a suite… read more here.

Derivation of the Early Carboniferous Wedgeport pluton by crystal fractionation of a mafic parental magma: a rare case of an A-type granite within the Meguma terrane (Nova Scotia, Canada)

DOI: 10.1017/s0016756819000694
Abstract: Abstract The Cambrian–Ordovician metasedimentary rocks of the Meguma terrane (Canadian Appalachians) were extensively intruded by silicic plutons during Middle Devonian to Early Carboniferous times. Syn-plutonic but volumetrically minor mafic-ultramafic intrusions were also emplaced. In most… read more here.
