Magnetostratigraphy of cave sediments, Wyandotte Ridge, Crawford County, Indiana: towards a regional correlation
Cave ; Geochronology ; Indiana ; Kentucky ; Palaeomagnetism ; Polarization ; Stratigraphiccorrelation ; Stratigraphy ; United States
The polarity of 42 sediment samples obtained from 21 sites in Wyandotte Cave and five smaller satellite caves in Wyandotte Ridge, southern Indiana, is used as a basis for a magnetostratigraphic correlation with sediments in Mammoth Cave, Kentucky.

Within the context of the new age control, the purposes of this paper are to: 1) identify, map and correlate fluvial terraces along the lower Susquehanna River; 2) assign ages to the terraces by downstream correlation to the fluvial stratigraphic
On the correlation of Eurasian terrestrial stratigraphy in Late Cenozoic times in Loess and the Quaternary: Chinese and Hungarian case studies.
The vast areas of Late Cenozoic terrestrial sediments have given rise to stratigraphical systems primarily based on mammal successions. Recent progress allows a broad scale international correlation between Europe, South and East Asia and North
Correlation of Pleistocene deposits in the Vienna and Komarno basins in Glaciations quaternaires dans l'Hémisphère Nord.
The studied territory is situated in an extraglacial area which represents a connecting link for the stratigraphicalcorrelation of continental glaciation extending into northern Moravia and the Alpine glaciation in Austria. At the beginning
Obstacles to quantitative lithostratigraphic correlation in Geomathematical and petrophysical studies in Sedimentology. An international Symposium.
Accurate definition of discrete correlative intervals within long sequences will perhaps be the most difficult problem. Accurate identification of significant gaps or breaks in a stratigraphic sequence is troublesome and solution of the correlation
problem will require a more detailed understanding of what effects these features have on various correlation methods. Accurate placement of boundaries once discrete units are recognized, seems to require multivariate classification techniques.
The granulometric composition and sorting of loesses and interbedded soils are studied for stratigraphic subdivision and correlation of the loess-paleosol sequence in Moldova. Distinctive features of loess and paleosol horizons of different age
are identified and general characteristics of the mineral composition are described that together with other lithological characteristics, improve reliability of stratigraphic operations.
On understanding the range and stratigraphic position of the Pannonian in Problems of the Neogene and Quaternary in the Carpathian Basin.
Based on a joint analysis of molluscs, ostracods and mammals as well as available geological and paleogeographical information, an attempt was made to correlate the Pannonian sediments with those of Eastern and Mediterranean. DLO).
Stratigraphiccorrelation of well logs: an automated approach in Geomathematical and petrophysical studies in Sedimentology. An international Symposium.
A system for automated correlation of digitized well logs based on lithostratigraphic characters has been developed. Modular in design and concept the system employs a mean value, moving window algorithm for zoning digitized well logs, a stretching
algorithm, a cross-correlation program, and a mapping function that highlights correlations between zones. In an application of this system to the Upper Glen Rose Formation of northeastern Texas, a number of distinct lithostratigraphic zones were detected
of these different deposits and their stratigraphicalcorrelations from paleobotanical data and from 14C datations are discussed. The complete stratigraphical series is believed to include the Riss-Würm, the Mesowürm and the Neowürm.
A palynological and stratigraphical study has been performed on glacial, interglacial and interstadial deposits outcropping in the Dranse river valley and which have been reached by two drill holes (Sionnex and Royal) near Evian. Ages

In this paper, the A. suggests a correlation of later Pleistocene interglacial paleosols from Normandy (St. Pierre les Elbeuf) in western Europe to the Ukraine in eastern Europe based on soil characteristics and dates from selected key sites.
The use of duricrusts and topographic relationships in geomorphological correlation : conclusions based in Australian experience

Duricrusted surfaces provide morphostratigraphic markers which are useful in preliminary extrapolation and correlation at the local and regional scales. Particular reference is made to ferruginous and siliceous cappings. Problems broached include
and deep-sea cores from the Bay of Bengal and Indian Ocean. The Toba ash thus can be used as an event marker for regional and global Quaternary correlation.
Correlation of Late Pleistocene glaciolacustrine and marine deposits by means of geomagnetic secular variation, with examples from northern New York and southern Ontario

This paper provides an example of an approach to stratigraphiccorrelation of glacial sequences that combines studies of glacial sediments related to these former ice borders, with analyses of the secular changes recorded in the depositional
Glaciotectonics and the problem of correct stratigraphy and correlation of the Quaternary deposits in the areas of Pleistocene inland glaciations in Glaciations quaternaires dans l'Hémisphère Nord.
Some types of deformations are difficult to recognize in exposures and unrecognizable in bore holes. The failure to recognize that glaciotectonic disturbances occur leads to mistaken constructions, not only stratigraphical but also
Interregional paleopedological Pleistocene correlation of the USSR loess regions in Lithology and stratigraphy of loess and paleosols.
Investigations were carried out in the Don, Upper Oka, Middle Volga basins, the Ural Foreland, souther part of the West-Siberian plain and in Soviet Central Asia and Georgia. 15 Pleistocene stages are identified with the corresponding stratigraphic
Correlation of the Rockland ash bed, a 400,000-year-old stratigraphic marker in northern California and western Nevada, and implications for Middle Pleistocene paleogeography of central California
Stratigraphic relations of the Rockland ash bed and older tephra layers in the Great Valley and near San Francisco suggest that the southern Great Valley emerged above sea level about 2 my ago, that its southerly outlet to the ocean was closed
