VOLCANISM AND VERTICAL TECTONICS IN THE PACIFIC BASIN RELATED TO GLOBAL CRETACEOUS TRANSGRESSIONS by Schlanger, S, Jenkyns, H, Premolisilva, I

“…The dominance of volcanic processes and the importance of vertical tectonics in the geological evolution of the Pacific Basin has been recognised since the time of Charles Darwin. …”

The age, origin and tectonic significance of Mesozoic sediment-filled fissures in the Mendip Hills (SW England): implications for extension models and Jurassic sea-level curves by Wall, G, Jenkyns, H

“…Major implications of this study are that: (1) the presence of seismically unresolvable sediment-filled fissures in supposedly rigid fault blocks can lead to a significant underestimate of regional extension based on the restoration of motion on normal faults on seismic-reflection profiles, and (2) the isolation of pulses of tectonic activity with a temporal resolution of 10^5 - 10^6 years may provide a means of identifying a tectonic signal in relative sea-level curves derived from the Jurassic sedimentary record.…”

The structural and sedimentological evolution of the Lagonegro zone, Southern Italy by Wood, A, Wood, Andrew William

“…Contrasting patterns of siliceous and calciclastic sedimentation developed during the Jurassic, probably imposed by renewed extensional tectonics; coeval calciclastic deposition in a small, and at times anoxic marginal basin is recorded in the Monte Foraporta Unit. …”

Pelagic environments. by Jenkyns, H

“…Various open-sea environments are outlined, divided on the basis of tectonics, topography and geography. -after Author…”

Ophiolites in ocean-continent transitions: from the Steinmann Trinity to sea-floor spreading by Bernoulli, D, Jenkyns, H

“…Before the theory of plate tectonics took hold, there was no coherent model for ocean-continent transitions that included both extant continental margins and fragmentary ancient examples preserved in orogenic belts. …”

Basins and swells and the evolution of an epeiric sea (pliensbachian-bajocian of Great Britain) by Sellwood, B, Jenkyns, H

“…These, presumably extensional, tectonics were probably the driving force behind the formation of the whole north European epeiric sea and must be related, in turn, to the opening of the oceanic central Atlantic and Alpine--Mediterranean Tethys.…”

The anatomy of mesozoic carbonate platform-margins, southern Appenines, Italy by Whiteman, M, Whiteman, Mark Ian

“…The results of onedimensional subsidence modelling are presented in order to separate and describe the signals of local tectonics and relative sea-level fluctuations affecting the southern passive-margin of Mesozoic Tethys.…”

Palaeoceanography and sedimentology of a mid-Cretaceous Greensand by Hart, S, Hart, Stephen Francis

“…The regional signal was modified by local tectonics, including occasional synsedimentary faulting and the development of thinned successions and complex condensation horizons over broad submarine highs. …”

Base of the Toarcian Stage of the Lower Jurassic defined by the Global Boundary Stratotype Section and Point (GSSP) at the Peniche section (Portugal) by Da Rocha, R, Mattioli, E, Duarte, L, Pittet, B, Elmi, S, Mouterde, R, Cabral, M, Comas-Rengifo, M, Gómez, J, Goy, A, Hesselbo, S, Jenkyns, H, Littler, K, Mailliot, S, De Oliveira, L, Osete, M, Perilli, N, Pinto, S, Ruget, C, Suan, G

“…The Pliensbachian/ Toarcian boundary (PLB/TOA) is contained in a continuous section forming over 450m of carbonate-rich sediments. Tectonics, syn-sedimentary disturbance, metamorphism or significant diagenesis do not significantly affect this area. …”

The Cenomanian- Turonian Oceanic Anoxic Event, II. Palaeoceanographic controls on organic-matter production and preservation. by Arthur, M, Schlanger, S, Jenkyns, H

“…Sea level, which may be responding to some volcano-tectonic event, is the common link and ultimately the driving force for orgC deposition in globally distributed basins under different climatic and ocean circulation regimes. …”

PALAEOCEANOGRAPHY OF MESOZOIC RIBBON RADIOLARITES by Jenkyns, H, Winterer, E

“…The peculiarities of the chert-argillite couplet we relate primarily to variations in surface-water productivity on a tens-of-thousands-of-years scale, to a lesser extent to redeposition from turbidity and particularly bottom currents, and diagenesis, the latter being accentuated by the pressure-temperature gradients imposed during major tectonic events: ribbon cherts are unique to orogenic belts. …”

Speculations on the genesis of crinoidal limestones in the Tethyan Jurassic by Jenkyns, H

“…They may also occur in tectonic fissures or as turbidites in basinal sequences. …”

Cenomanian-Turonian carbonate and organic-carbon isotope records, biostratigraphy and provenance of a key section in NE Sicily, Italy: Palaeoceanographic and palaeogeographic impli... by Scopelliti, G, Bellanca, A, Erba, E, Jenkyns, H, Neri, R, Tamagnini, P, Luciani, V, Masetti, D

“…In eastern Sicily, a series of highly organic-rich black shales occur as exotic blocks (~ 100 m across) floating in tectonized sediments (Argille Varicolori Unit containing olistoliths of Cretaceous-Palaeogene age). …”

STABLE ISOTOPE STUDY OF THE CYCLIC DIATOMITE-CLAYSTONES FROM THE TRIPOLI FORMATION, SICILY - PRELUDE TO THE MESSINIAN SALINITY CRISIS by Mckenzie, J, Jenkyns, H, Bennet, G

“…The restriction of the Tripoli Sea during low sea-level stands required the presence of a shallow Atlantic-Mediterranean sill. Progressive tectonic constriction of the connection between the two water bodies, or global eustatic sea-level lowering, is indicated by the extensive dolomitization of the uppermost transitional unit of the Tripoli Formation and the calcitized "evaporite" beds of the Calcare di base. …”

The sequence stratigraphy of the Lower Jurassic of Western Europe by Parkinson, DN

“…</p> <p>The cycles observed in the English sections appear to be manifest widely across western Europe in a variety of tectonic and sedimentary settings. Sharp basinward facies shifts (candidate sequence boundaries) do not appear to be synchronous between basins.…”

Stratigraphy, paleoceanography, and evolution of Cretaceous Pacific guyots: Relics from a greenhouse earth by Jenkyns, H, Wilson, P

“…Dating the youngest levels of these platform carbonate shows that the shallow-water systems drowned sequentially in the order in which plate-tectonic movement transported them into low latitudes south of the Equator (paleolatitude ∼0°-10° south). …”

Global correlation of Upper Campanian - Maastrichtian successions using carbon-isotope stratigraphy: development of a new Maastrichtian timescale by Voigt, S, Gale, A, Jung, C, Jenkyns, H

“…The CMBE covers a time span of 2.5 Myr and reflects changes in the global carbon cycle probably related to tectonic process rather than to glacio-eustasy. The duration of the high-frequency δ13C variations instead coincides with the frequency band of long eccentricity, indicative of orbital forcing of changes in climate and the global carbon cycle. © 2012 Gebrüder Borntraeger, Stuttgart, Germany.…”
