Abstract Six species of bryozoa are described from the upper Ordovician of the south flank of Montagne Noire in southern France: Crepipora vesiculosa n. sp., Atactoporella irregularis n. sp., Cyphotrypa magna n. sp., Heterotrypa magnopora n. sp., Trematopora hirsuta n. sp., and Enallopora lineata n. sp.

The abbey of Saint-Gilles-du-Gard near Arles in the south of France was one of the most prominent pilgrimage sites in medieval Europe. Recent archaeological investigation has shown that construction of the abbey church, one of the most significant Romanesque pilgrimage churches in southern France, began ca. 1170/1180. The lower church (crypt) with the tomb of St. Giles (Lat. Aegidius, Fr. Gilles) and some of the walls of the upper church belong to that period. A well-preserved Cyrillic graffito was discovered on a pier of the upper church, close to the spot where the tomb of St. Giles is located in the crypt below. The text contains a prayer with a common formula: GI POMЪZI | RABU SVЪ|EMU SЬMKЪ|VI NINOSLA|VICHIU ‘Lord, help your servant Semko, son of Ninoslav.’ Palaeographic and linguistic analysis shows that the graffito is of Russian origin. It was probably made at some time between 1180 and 1250 by a pilgrim travelling from Russia to Santiago de Compostela, and it is the most geographically remote Old Russian graffito inscription discovered so far in western Europe.

Abstract The Sainte-Victoire mountain in southern France has been considered the overturned southern limb of the Vauvenargues anticline, but the structure east of the Delubre fault is complicated by an oblique fold. The western margin is concealed by transgressive Tortonian (middle Miocene) beds covering the plateau of Beaumettes. The anticline probably is upper Cretaceous. Folding was renewed in the upper Lutetian (middle Eocene), and resulted in overturning and thrust faulting of the south limb. Subsequent normal faulting compartmented the mass, resulting in selective differential movement of blocks as horsts and grabens. The term piano keys structure is given to this type of structure.

Abstract During the middle and upper Eocene relatively high land masses were present in the southern part of the Minervois basin, Languedoc, France, with numerous streams which contributed to deposition of fluvial deposits northward. In the northern part of the basin, on the south border of the Montagne Noire, the relief was more subdued, with extensive lakes. The great thicknesses of lacustrine deposits are attributed to subsidence of the basin.

The Meaford–Dundas Formation in southern Ontario is a medium gray shale with good fissility and resistant interbeds of gray fossiliferous limestones and siltstones. The hard layers are up to 20 cm in thickness and comprise 10 to 20% of the formation. The shale layers vary in thickness from 50 cm to 2 m.The clay minerals are principally illite, iron-chlorite, and small amounts of vermiculite and mixed-layer types. The carbonate content seems constant across the area at about 4 to 5% of the formation, except for the southwestern area where the carbonate increases to 20 or 25%. This increase is chiefly in dolomite content, a feature which reflects such factors as original conditions of deposition and possibly diagenesis subsequent to burial. The quartz content in the shale beds, and especially in the hard interbeds, increases towards the north to an average of 35 to 40% compared with 10 to 15% in the south. Framboids (aggregates of pyrite grains in spheroidal clusters) are a striking feature of the shale beds of the Meaford–Dundas Formation in the Meaford area.Fabric studies by means of X-ray diffraction patterns and scanning electron photomicrographs reveal, in most cases, high parallelism of clay platelets in the bedding planes, resulting in the good fissility of the shale.The principal source rock areas are the Appalachian orogen in the east (Taconic Mountains), which probably supplied most of the clay minerals and some quartz, and the Canadian Shield in the north, which provided the basin of sedimentation in the south with heavy minerals and additional quartz.

AbstractLower Cambrian shallow-water carbonates enclosing microbial structures are documented for the first time from the upper Lastours Member of the Montagne Noire (southern France). Microbial organisms constructed self-supported boundstones resulting in the formation of exclusively microbial-accreted buildups, which exhibit three main types of non-skeletal microbialites: planar stratiform stromatolites, dome-shaped stromatolites and nonlaminated (thrombolitic) biostromes. In addition, thrombolitic boundstones display four distinct microbial microstructures: clotted andRenalcis-like forms, branching bushy forms, clusters of unbranching straight filaments and crustose forms.The upper member of the Lastours Formation records an upward transition from a shalydominant open shelf to a protected shelf environment bounded by a surface representing a major subaerial exposure. Initially, at the inception of the highstand systems tract, flat stratiform stromatolites formed on open sea subtidal shaly substrates, while stacked domal stromatolites developed in peritidal areas which record subaerial exposure. In contrast, prograding shoal barriers of the transgressive systems tract favoured the establishment of thrombolitic boundstones in protected (back-shoal) environments.
