...S. KERSHAW Abstract Silurian stromatoporoid-dominated reefs of Gotland, Sweden, are bioherms and biostromes formed during phases of reduced clastic supply. Well-exposed examples are in the early Wenlock Högklint Formation and middle Ludlow Hemse Group. Reef development culminated in shallow water...

...) referred to as ‘an uncommonly good type-bed’. The top of the Hemse Group is a discontinuity surface at least from the Botvide area in the northeast to the subsurface of the Ronehamn area in the southwest. During this study the discontinuity surface was identified c. 1.2 km southwest of the drilling point...

... knowledge about the geometry and orientation of the microcracks. We have developed a formulation of the theory for a transverse isotropic rock, which was loaded parallel to the bedding plane, and we found that it can be described theoretically as an orthorhombic rock. We also found out how properties...

...-scale cycles are typically characterized by coarsening-upward, locally cross-bedded encrinitic material capped by a sharp erosional surface. These bounding surfaces change progressively upsection from simple planar to low-relief scalloped erosional surfaces to complex polyphase surfaces formed...
