...JOSEPH T. HANNIBAL; NICHOLAS A. RESER; JULIA A. YEAKLEY; THERESA A. KALKA; VERONICA FUSCO Abstract French and North American cherts used for millstones during the late eighteenth century and nineteenth century in Ohio are generally similar in color, hardness, presence of cellular porosity...

...Patrizia Santi; Alberto Renzulli; Riccardo Gullo Abstract A comprehensive investigation and classification of volcanic millstones of the Greek and Roman periods found on three islands of the Aeolian archipelago (Lipari, Salina and Filicudi) has been reported. Most of the analysed hopper-rubber...

...Luigi BUFFONE; Sergio LORENZONI; Mauro PALLARA; Eleonora ZANETTIN Abstract This study concerns 47 hourglass and 25 rotary-hand millstones from Pompei. All of them are made of volcanic rocks. Most samples were chemically analysed and all were studied by optical microscopy. Out of the rotary-hand...

...Alberto RENZULLI; Patrizia SANTI; Giovanni NAPPI; Mario LUNI; Daniele VITALI Abstract Rectangular hopper-rubber (Olynthian-style) and rotary (Pompeian-style) millstones were found, respectively, in the archaeological sites of Monte Bibele (4th–3th century B.C., Etruscan-Celtic Age) and Fossombrone...

...Sergio LORENZONI; Mauro PALLARA; Eleonora ZANETTIN Abstract Twenty-three samples of volcanic-rock Bronze Age (XIX - X C. b.C.) millstones from ten archaeological sites of Apulia were studied by both petrological and geochemical methods. All the millstones are of the saddle-type, and all are made...

...Priscia Oliva; Didier Beziat; Claude Domergue; Catherine Jarrier; Francois Martin; Bernard Pieraggi; Francis Tollon Abstract Roman rotary millstones are commonly reported in ancient mines and iron-making centres around the Mediterranean basin. The millstones from the iron-making site of Les Martys...

...C. G. Godwin Abstract A new species of Anthraconaia resembling A. modiolaris found in the upper of two Lingula-bearing marine bands in the middle part of the sequence assigned to the Millstone Grit at Acton Cleugh (England) indicates that at least some 200 feet of the so-called Millstone Grit...

...Michael D. Wright Abstract "The extent of compaction of arenaceous sediments in the Millstone Grit (Namurian) rocks of the central Pennine Carboniferous has been estimated by determining the extent to which quartz grains are in contact with one another in thin sections. Where clay is present...

...Michael D. Wright Abstract "Most of the cross-bedding in the central Pennine Millstone Grit occurs in the coarse sandstones and indicates that they are probably fluvial in origin. The cross-bedding often occurs within sheets of sandstone, and it is suggested that each sheet was deposited during one...

... interval corresponds to the development of the Millstone Grit of the Pennine Basin, which was deposited by a southward-flowing fluvial system. Heavy mineral analysis indicates that there are common elements to the provenance of Late Westphalian A sandstones in East Greenland and the Namurian Millstone Grit...

...C. N. Waters; D. Millward; C. W. Thomas Summary In the Northumberland–Solway Basin and Alston Block of northern England, some aspects of the stratigraphical and sedimentological relationships between the Millstone Grit Group, the Stainmore Formation (Namurian part of the Yoredale Group...

...David Banks Abstract A pilot study has been performed to ascertain the baseline hydrochemistry of both shallow (springs) and deep (borehole) groundwaters of the Millstone Grit and Coal Measures. In terms of major ion composition the majority of the shallow groundwaters in the two formations...

... for determining a unique provenance, new samples have been collected from the Namurian Millstone Grit Group of Yorkshire, England. Two K-feldspar 206 Pb/ 204 Pb isotope populations between 12.5 and 15.5 and c. 18.4 are consistent with Archaean–Proterozoic basement and Caledonian granites, respectively. Zircon U...

...Matthew J. Brettle; Colin N. Waters; Sarah J. Davies Abstract The early Marsdenian substage (Millstone Grit Group) of the Pennines comprises repeated deltaic cycles separated by ammonoid-bearing marine bands. This cyclicity, controlled by the combined forces of glacio-eustasy and modulations...
