Geological Quarterly, 2005, 49 (3): 317–330 The Ciechocinek Formation (Lower Jurassic) of SW Poland: petrology of green clastic rocks Paulina LEONOWICZ Leonowicz P. (2005) — The Ciechocinek Formation (Lower Jurassic) of SW Poland: petrology of green clastic rocks. Geol. Quart., 49 (3): 317–330. Warszawa. The Lower Jurassic Ciechocinek Formation from the Czêstochowa-Wieluñ region of SW Poland comprises greenish-grey muds and silts as well as poorly consolidated mudstones and siltstones with lenticular intercalations of fine-grained sands, sandstones and siderites. Analysis of a mineral composition indicates that the detrital material was derived mainly from the weathering of metamorphic and sedi- mentary rocks of the eastern Sudetes with their foreland and of the Upper Silesia area, and that this material underwent repeated redeposition. The Fe-rich chlorites which give the green colour to the mudstones of the Ciechocinek Formation are most probably early diagenetic minerals, genetically linked with the deposition in a brackish sedimentary basin.

The occurrence of calcium phosphate in the Mesozoic and Tertiary of Eastern England Albert Horton Abstract: Phosphate is a minor component of Mesozoic and Tertiary formations. It occurs widely scattered as nodules in argillaceous sediments, but is commonly concentrated in pebble beds and may be found replacing fossils. Phosphatic animal remains are rare and commonly occur immediately above major discontinuities, and fossilised animal faeces (coprolites) are extremely rare. Phosphatic pisoliths occur at only one horizon. In Eastern England calcium phosphate occurs as coprolites, bones, fossil replacements, ill-defined impregnations, nodules, pebbles, pisoliths and hardgrounds in Mesozoic and Tertiary strata. Many geologists (eg. Horton et al., 1974, p.35) have been guilty of imprecise use of these terms. Using local examples it is possible to obtain a clear understanding of the diverse origins of these deposits. Phosphorus occurs as a minor element in igneous rocks. Weathering and erosion result in transfer of the element within detrital grains and in solution. In marine environments, the phosphorus may be concentrated by physical, chemical and biological processes, Figure 1.

Paleontological Contributions
THE UNIVERSITY OF KANSAS PALEONTOLOGICAL CONTRIBUTIONS May 15, 1970 Paper 47 SIGNIFICANCE OF SUTURES IN PHYLOGENY OF AMMONOIDEA JURGEN KULLMANN AND JOST WIEDMANN Universinit Tubingen, Germany ABSTRACT Because of their complex structure ammonoid sutures offer best possibilities for the recognition of homologies. Sutures comprise a set of individual elements, which may be changed during the course of ontogeny and phylogeny as a result of heterotopy, hetero- morphy, and heterochrony. By means of a morphogenetic symbol terminology, sutural formulas may be established which show the composition of adult sutures as well as their ontogenetic development. WEDEKIND ' S terminology system is preferred because it is the oldest and morphogenetically the most consequent, whereas RUZHENTSEV ' S system seems to be inadequate because of its usage of different symbols for homologous elements. WEDEKIND ' S system includes only five symbols: E (for external lobe), L (for lateral lobe), I (for internal lobe), A (for adventitious lobe), U (for umbilical lobe). Investigations on ontogenetic development show that all taxonomic groups of the entire superorder Ammonoidea can be compared one with another by means of their sutural development, expressed by their sutural formulas. Most of the higher and many of the lower taxa can be solely characterized and arranged in phylogenetic relationship by use of their sutural formulas. INTRODUCTION Today very few ammonoid workers doubt the (e.g., conch shape, sculpture, growth lines) rep- importance of sutures as indication of ammonoid resent less complicated structures; therefore, phylogeny. The considerable advances in our numerous homeomorphs restrict the usefulness of knowledge of ammonoid evolution during recent these features for phylogenetic investigations. -
Warwickshire's Jurassic Geology
Warwickshire’s Jurassic geology: past, present and future Jonathan D. Radley Abstract. Jurassic strata were extensively quarried in Warwickshire, during the 19th and early to mid 20th centuries, but much of the succession is now poorly exposed. Selected sites are afforded statutory and non-statutory protection as Sites of Special Scientific Interest and Regionally Important Geological and Geomorphological Sites. Warwickshire’s Jurassic history is outlined, demonstrating the value and purpose of the currently protected sites as repositories of stratigraphic, palaeontological and palaeoenvironmental data. The fields, hills and villages of southern and eastern structural hinge throughout much of Lower and Warwickshire, central England, conceal a marine Middle Jurassic time (Horton et al., 1987). This sedimentary succession of Lower and Middle separated the London Platform and East Midlands Jurassic age (Figs 1 and 2). This is at least 400 Shelf in the east from the Severn (or ‘Worcester’) metres thick (Williams & Whittaker, 1974) and Basin in the west (Sumbler, 1996). West of the Axis, spans about 40 million years of Earth history. The in south-western Warwickshire, the Lower Jurassic beds demonstrate a gentle regional dip towards the succession features a laminated, calcilutite- south-east and are affected by numerous normal dominated Hettangian development (Wilmcote faults (Institute of Geological Sciences, 1983), as Limestone Member), a more arenaceous facies well as cambering, landslipping and periglacial development of the Pliensbachian Marlstone Rock cryoturbation (Fig. 3). Unconsolidated Quaternary deposits locally cover the Jurassic sediments, notably in the Dunsmore area of eastern Warwickshire (British Geological Survey, 1984).
