Among the important geological attributes of the small Cumbraes Basin in the southwestern off-shore Midland Valley of Scotland, the 4 km-long, fragmented but well-exposed section through the Devonian-Carboniferous boundary sequence in southern Great Cumbrae island ranks highly. In a continuous short stretch of the south and west coasts, large portions of this sequence are superbly preserved in tide-washed strandline surfaces and in old post-glacial sea cliff. This enhanced exposure leaves no doubt that the outcrops belong to two, immediately successive, members of the Kinnesswood Formation -- the lower the Doughend Sandstone, the upper the Foul Port Mudstone – and that they provide some of the best available exposures on which to base description and interpretation. The facies of the fluviatile Doughend Sandstone shares many characteristics with the underlying Kelly Burn Sandstone of the Upper Old Red Sandstone, whereas that of the Foul Port Mudstone is distinct and unusual, attributed to local tectonics, influenced by movements on older and more major fractures such as the Highland Boundary Fault, with sediment accumulation taking place in a playa-lake complex of considerable extent.
在苏格兰米德兰谷地西南部的小cumbres盆地的重要地质属性中，位于大Cumbrae岛南部的泥盆纪-石炭系边界层序中长4公里、破碎但暴露良好的剖面占有重要地位。在南海岸和西海岸的一段连续的短段中，该序列的大部分在潮汐冲刷的海岸线表面和古老的冰川后海崖中被完好地保存下来。这种增强的暴露毫无疑问地表明，这些露头属于Kinnesswood组的两个连续的成员——下部为Doughend砂岩，上部为犯规港泥岩——它们提供了一些最好的暴露，可以作为描述和解释的基础。道恩德(Doughend)流质砂岩相与上古红砂岩(Upper Old Red Sandstone)的凯利Burn砂岩(Kelly Burn Sandstone)具有许多共同的特征，而犯规港(Foul Port)泥岩的相则是独特而不寻常的，这是局部构造的结果，受高地边界断层(Highland Boundary Fault)等更古老、更主要裂缝运动的影响，沉积物聚集在相当程度上的湖湖复合体中。

Foraminiferal diversity and taxa richness from beds transitional between the Asbian and Brigantian substages (Middle Mississippian) show patterns of secular change which allow detailed inter-regional correlations to be established. Foraminifera from the Askrigg Block, Stainmore Trough, Alston Block, South Cumbria Shelf and Solway Basin show similar secular changes (foraminiferal trends, FTs), allowing correlation to be made with the basal Brigantian Stratotype at Janny Wood. Despite the absence of consistent microfossil first occurrence markers for the recognition of the base of the Brigantian, this horizon can be confidently recognised by means of foraminiferal trends. The FTs allow the precise location of the base of the correlated Brigantian in sections where this boundary was questioned or controversial in previous studies, as well as to amend the position of the foraminiferal zones and subzones during the late Asbian and basal Brigantian. This type of analysis when used in combination with foraminiferal zonations, emergent surfaces and lithological cyclicity, together, provide a robust means for high-resolution correlation. This methodology, provides the least uncertainty in sections that have been most densely sampled, whereas for less intensely sampled sections there is more correlation uncertainty.

A new specimen of a rare large theropod dinosaur print of Middle Jurassic age is described from the Long Nab Member of the Scalby Formation, Cleveland Basin, Yorkshire. This is only the sixth specimen of this type recorded from the Cleveland Basin since they were first discovered in 1934. The present specimen is included in the same, but slightly modified morphotype Bxviii as some of the previous ones, since it shows additional features including an elongated metapodium. The specimen is assigned to the ichnogenus Megalosauripus , and was possibly made by a Megalosaurus -like theropod. The elongated metapodium may be the result of resting or crouching behaviour.

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 in sediment supply, provides an important outcrop area for the application of sequence stratigraphic principles. A new correlation framework is presented where two orders of sequence are identified: – (1) a low-order sequence, within which marine bands (R 2a 1, R 2b 1, R 2b 2 and R 2b 3) represent a maximum flooding surface, and (2) high-order sequences nested within the low-order sequences. By integrating and correlating key exposures, historic well boreholes and field mapping, lateral changes in facies and facies association are observed, and palaeogeographic trends mapped. This allows the variation in sequence and systems tract stacking patterns to be interpreted. Three orders of Milankovitch cyclicity are inferred to control the sequence stacking patterns; long-duration (∼400ka) eccentricity oscillation controlling maximum flooding events represented by the R 2a 1 and R 2b 2 marine bands, sub-100ka obliquity oscillations (controlling the R 2b 1, R 2b 2 and R 2b 3 marine bands and intervening low-order sequence boundaries), and precessional frequencies (∼25ka) which may control the periodicity of the high-order sequences.

This paper re-introduces a forgotten subject, cannel coal, formed within very low gradient mire drainage systems. A minute part of the British Carboniferous rock volume, cannel was prized in the early Industrial Revolution for oil and gas, notably hydrogen. In this paper it is revisited to reveal under-reported palaeogeography, using modern mining and drilling data to give regional depositional insights. The focus is on the English East Midlands, in the southeast of the Pennine Basin. Early literature on other areas emphasised deposition in small lakes, assuming little connectivity. In the East Midlands, large lake deposits are connected by cannel-filled channels, from the basin's southern margins up to 100km north into Yorkshire. Interplays with fluvio-clastic systems are spread over a subtle but simple palaeoslope, north and northeast to the Gainsborough Trough sub-basin, with negligible structural disturbance during deposition of the Pennine Coal Measures Group. A gentle basement tilt is indicated. Mire drainage tangential to the central basin invites discussion on wider issues, including marine flooding into the basin. Mire longevity is discussed, this also being relevant to research on contaminant contents through coal-forming times.

Here, we describe the upper Pliensbachian to middle Toarcian stratigraphy of the Dove's Nest borehole, which was drilled near Whitby, North Yorkshire, in 2013. The core represents a single, continuous vertical section through unweathered, immature Lower Jurassic sedimentary rocks. The thickness of the Lias Group formations in the Dove's Nest core is approximately the same as that exposed along the North Yorkshire coast between Hawsker Bottoms and Whitby. The studied succession consists of epeiric-neritic sediments and comprises cross-laminated very fine sandstones, (oolitic) ironstones, and argillaceous mudstones. Dark argillaceous mudstone is the dominant lithology. These sediments were deposited in the Cleveland Basin, a more subsident area of an epeiric sea, the Laurasian Sea. We present a set of geochemical data that includes organic carbon isotope ratios (δ 13 C org ) and total organic carbon (TOC). The δ 13 C org record contains a negative excursion across the Pliensbachian–Toarcian boundary and another in the lower Toarcian that corresponds to the Toarcian Oceanic Anoxic Event (T-OAE). Below the T-OAE negative excursion, δ 13 C org values are less 13 C-depleted than above it. We find no evidence of a long-term δ 13 C org positive excursion. TOC values below the T-OAE negative excursion are lower than above it. Sedimentary evidence suggests that, during much of the Pliensbachian–Toarcian interval, the seafloor of the Cleveland Basin was above storm wave-base and that storm-driven bottom currents were responsible for much sediment erosion, transport, and redeposition during the interval of oceanic anoxia. The abrupt shifts observed in the δ 13 C org record (lower Toarcian) are likely to reflect the impact of erosion by storms on the morphology of the δ 13 C record of the T-OAE.

A review of the exposures in the Cadeby Formation, Upper Permian (Lopingian Series) in South Yorkshire by the Sheffield Area Geology Trust revealed groups of previously undescribed sites near the base of the Sprotborough Member, at, and just above, the Hampole Discontinuity. These sites indicate: a wider degree of palaeoenvironmental variation along the Hampole Discontinuity surface than was previously evident; that the discontinuity surface is not laterally continuous; and imply some caution is needed when using these exposures as marker horizons. The field data is used to inform a palaeoenvironmental reconstruction for the period of the Hampole regression. A complex of near-offshore pools and islands, an area of partly exposed shoal and lagoon, and an embayment are identified.
