Turonian (Late Cretaceous) Ostracoda from Dover, south-east England
Ostracod assemblages from samples collected through the Turonian Stage of the Late Cretaceous from Dover, Kent, south-east England, consist of one hundred and three species group taxa. These are described and illustrated. This represents a significant increase in the knowledge of the Turonian …

The nature and significance of microtopographic effects on vegetation succession on selected glacier forelands, Jotunheimen and Jostedalen, Norway.
This extensive study investigates the relationship between microtopography, prevailing micro-environmental factors and vegetation, with particular reference to succession, on six glacier forelands at successively higher altitudes. The study is successful in answering the three main aims of the …

The structural architecture of seismogenic faults, Sierra Nevada, California; implications for earthquake rupture processes
Earthquake ruptures along tectonically active faults nucleate predominantly at depths of 5 to 12km in the crust, so the portions of faults that slip in these events cannot be directly observed. The geometry and composition of seismogenic faults controls the nucleation, propagation and termination …

The initiation and evolution of ignimbrite faults, Gran Canaria, Spain
Understanding how faults initiate and fault architecture evolves is central to predicting bulk fault zone properties such as fault zone permeability and mechanical strength. The study of faults at the Earth’s surface and at near-surface levels is significant for the development of high level …

Zircon behaviour in low temperature environments
Abstract Zircon in mudstones, sandstones and greenschist facies metasediments has been investigated using conventional SEM techniques (BSE, CL and SE imaging) and reveals highly variable microstructures and textures. In these rocks, zircon readily responds to low temperature events due to radiation …

Rare and problematic taxa from the Much Wenlock Limestone Formation
The Much Wenlock Limestone Formation (Silurian: Wenlock, Homerian) of England and Wales contains a diverse invertebrate fauna including many rare and problematical taxa. This study investigates the palaeobiology and palaeoecology of five such groups: asteroids (starfish), the crinoid Calyptocymba …

Early cretaceous belemnites from Southern India
The Cauvery Basin has been the subject of intense research into the bio- and lithostratigraphies of the basin fill since Blanford and Stoliczka (1861-65). The Karai Formation ranges from the Early Albian through to the late Turonian in age. The belemnites in this study were collected from the …

Quaternary to recent drainage evolution of the Rambla de Lucainena, SE Spain
The study is focused on the small drainage catchment of the Rambla de Lucainena, situated between the Carboneras and Sorbas basins of the Almeria Province in SE Spain. Previous research has shown that this river has developed due to aggressive headcutting during the Plio/Pleistocene, which has been …

The geochemistry and petrology of the Rodrigues Ridge (Western Indian Ocean)
The Rodrigues Ridge is a linear east-west trending volcanic ridge, located between 18°S and 20°S in the western Indian Ocean. The trend of the Rodrigues Ridge is contrary to the ocean floor fabric of the underlying crust, which formed on the Central Indian Ridge (CIR) between ca. 48 My and 10 My. …

Development of the Platreef in the northern limb of the Bushveld Complex at Sandsloot, Mokopane District, South Africa
The Platreef is a Ni-Cu-PGE mineralised tabular body at the base of the Rustenburg Layered Suite in the northern limb of the Bushveld Complex. The reef lies unconformably on a footwall (floor) sequence of Transvaal Supergroup sedimentary rocks and Archaean granite/gneiss basement, and is overlain …

A stratigraphical, sedimentologial and palaeoenvironmental analysis of holocene and present-day coastal sedimentation: Wigtown Bay, S.W. Scotland
Evidence of Holocene marine transgression and regression in South-West Scotland is exhibited in the stratigraphical record of present and former coastal deposits. Remnant areas of Holocene coastal (including marine) sediments are preserved at the head of marine inlets and estuaries along the …

Structural geology of South Hadhramaut area Yemen Republic
The northern margin of the Gulf of Aden has a long history of extension from the Cambrian to the present. The dominant structures are related to Oligo-Miocene rifting in the early stages of development of the Gulf of Aden and they overprint Palaeozoic and Mesozoic structures. An area of 170 km by …

Cretaceous ostracoda of the super family Cytheracea from Iraq, their biostratigraphy and correlation with adjacent regions
The cretaceous ostracods of Iraq are poorly known, so the aim of the project was to study their taxonomy and to discover their value in correlation between wells in Iraq and between Iraq and neighbouring countries. The Cenomanian-Santonian ostracods of the superfamily Cytheracea were studied in …

The integration of petrologic and isotopic data from the Boulder Conglomerate to determine the age of the Navan orebody, Ireland
The Boulder Conglomerate is the Lower Carboniferous sedimentary allochthon deposited in the second order half graben created by major listric normal faults in the Navan area. The base of the Boulder Conglomerate comprises erosive-based, highly immature rock avalanches which are interbedded with …

The sedimentation and provenance of the Lower Old Red Sandstone Greywacke Conglomerate, southern Midland Valley, Scotland
The origin of the southern Midland Valley Old Red Sandstone Conglomerates is reviewed with the specific aim of determining the nature and location of the source for the Old Red Sandstone Greywacke Conglomerate. The Silurian Midland Valley has been viewed as either i) a fore-arc basin with a rising …
