The Elemental Stratigraphy of the South Caspian Lower Pliocene Productive Series
2014This study is the first attempt to quantify the chemical stratigraphy of the South Caspian Productive Series sediments, based on their macro- and microelemental compositions. The results show a good correlation between the content of some of the elements and the lithology of studied sediments, which allows chemostratigraphic units to be distinguished ...

THE STRATIGRAPHY OF THE CARADOC SERIES IN THE CROSS FELL INLIER
Proceedings of the Yorkshire Geological Society, 1959Summary The rocks of the Caradoc Series in the Cross Fell Inlier have been re-examined and their faunas, almost exclusively of shelly type, collected systematically. As a result a fairly detailed correlation with the stages of the south Shropshire succession is now possible.

Debatable questions of Boreal Triassic stratigraphy: boundary between middle and upper series
Russian Geology and Geophysics, 2008Abstract Various opinions on the position of the Middle/Upper Triassic boundary have been concisely reviewed. The lower boundary of the Carnian Stage is accepted at the base of the Trachyceras aon Zone. The recentmost data on biostratigraphy of boundary beds of the Ladinian and Carnian Stages of the Southern Alps, Himalayas, British ...

Strontium isotope stratigraphy of the Comanchean Series in north Texas and southern Oklahoma
Geological Society of America Bulletin, 2003Pioneering studies in north Texas and adjacent Oklahoma played an important role in the paleontologic and stratigraphic development of the Cretaceous in North America. We have used the results from 135 strontium isotope analyses from fossils and rocks collected from 43 sites to define the "middle" Cretaceous path of seawater 8 7 Sr/ 8 6 Sr during ...

Abstract A study of benthic Foraminifera from the Toarcian in Quercy (Aquitaine Basin, France) shows that micropaleontological assemblages are influenced by sea level changes. The percentages of coiled, and straight Nodosarridae (Lenticulina, Citharina) differ during periods of low sea level to high sea level.

Marine Geology, 1994
Abstract The ages and average sedimentation rates of four long sediment cores from the Norwegian-Greenland Sea were determined by using various 230 Th dating models. The results were then related to an independent time control ( δ 18 O stratigraphy) which was available for the cores under consideration.

Sequence Stratigraphy of the Cambrian and Ordovician Series in the Illizi Basin (Algeria)
2014The Cambro–Ordovician sediments of the Southeast Saharan Platform show a facies evolution from continent to platform rather than from platform to basin and, for that reason, faciological stratigraphy (Homewood et al. 1992) has been applied. The genetic sequences are limited at their bases and tops by Maximum Flooding Surfaces (MFSs).

Sequence stratigraphy and micropaleontology of the Triassic series from the southern part of Tunisia
Journal of African Earth Sciences (and the Middle East), 1993Abstract The Triassic series in the southern part of Tunisia, only known from the oil exploration wells in the Kirchaou area (sandy series from Early Scythian to Ladinian) and in its Djeffara/Dahar-North outcrops (alternating series from Ladinian to Rhaetian) is now subdivided into 10 Depositional Sequences (DS) sensu Vail et al.
