Geological Journal, EarlyView.Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Late Campanian–Maastrichtian sequence stratigraphy from Kurdistan foreland basin, NE/Iraq
Journal of Petroleum Exploration and Production Technology, 2018 The Kurdistan foreland basin (NE Iraq) was formed as a result of the ophiolite–radiolarites obduction of the Iranian plate on the Arabian Plate. Extensive fieldwork for the determination of nine facies associations has been integrated with the planktonic

Geological Journal, EarlyView.In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the

Journal of Applied Sciences and Environmental ManagementA combination of palynological and palynofacies data are used as lithological evidence to describe sequence stratigraphic framework. Hence, the objective of this paper as to deploy the palynological and sequence stratigraphy framework of Campanian ...

Sequence Stratigraphy and Microfacies of the Middle Ordovician Yijianfang Formation in the Tarim Basin, NW China [PDF]
LithosphereIt is of great significance for further exploration in deep-burial carbonates to clarify the distribution of sedimentary microfacies within the high-precision sequence framework and to analyze how the sequence stratigraphy and lithologic types control ...

Sequence stratigraphy and eustatic sea-level change: the role of micropalaeontology
, 1992 . Following the May 1992 meeting in Dijon, which initiated an international project on the “Sequence Stratigraphy of European Basins”, it seems an appropriate time to consider the contribution micropalaeontology can make to the science of sequence ...

Geological Journal, EarlyView.New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

Geological Journal, EarlyView.The rhyolitic ignimbrite and K‐feldspar granite porphyry from the Wangmushan mining district, northern Fujian yield ages of 173.8 ± 0.8 and 102.6 ± 0.4 Ma, respectively. Geochemical data, zircon trace elements, whole‐rock Sr–Nd–Pb isotope data, and zircon Hf isotopic compositions indicate that the rhyolitic ignimbrite originated from partial remelting ...

Guidelines for seismic sedimentologic study in non-marine postrift basins
Petroleum Exploration and Development, 2012 This study summarizes the research experiences of non-marine seismic sedimentology in recent years in China and uses Qijia area, Songliao Basin, as a template to establish general guidelines for seismic sedimentology.
