Belt Series of the North: Stratigraphy, Sedimentation, Paleontology

Bulletin of the Geological Society of America, 1937
INTRODUCTION The writers9 study of the Belt series began in 1927 and was continued in 1928 and 1932. Field work was virtually completed in 1934, when a grant from the Geological Society of America financed twelve weeks in Glacier and Waterton Lakes national parks and visits to other Belt outcrops.

Stratigraphy of Upper Cretaceous Series in Mississippi and Alabama

AAPG Bulletin, 1938
ABSTRACT The Upper Cretaceous sediments of the eastern Gulf region crop out in a crescentic band around the southwestern end of the plunging Appalachian Highlands in a belt 500 miles long and up to 75 miles wide. Their maximum thickness is estimated to be about 2,300 feet. The Tuscaloosa formation is thickest in west-

Ordovician series and stages in Chinese stratigraphy: steps toward a global usage

Alcheringa, 2001
The first Chinese Ordovician series was erected by Lee & Chao (1924). Since then, many regional Ordovician series and stage names have been established and mostly published in Chinese. The present study is a review of these regional units with a discussion of their definitions and correlation to the international standard. Among them, the Ichang series,

The Stratigraphy of the Siwalik Series in the Northern Potwar, Punjab, Pakistan

Quarterly Journal of the Geological Society of London, 1951
Summary Detailed mapping of the Jhamat area in the west and of the Soan syncline in the east forms the basis of revision of the stratigraphy of the Siwalik Series in the northern Potwar region. The succession is here affected by facies changes of regional significance :— 1.

Status of the Talladega series in southern Appalachian stratigraphy

Bulletin of the Geological Society of America, 1936
THE TALLADEGA SERIES DISTRIBUTION The Talladega series has been traced by the writer from Alabama, where it is typically exposed, across northwest Georgia, into North Carolina and Tennessee. The series occupies a belt, trending northeast, 300 miles in length and 1 to 25 miles in width. The belt is separated in most places from the fossiliferous rocks

The Elemental Stratigraphy of the South Caspian Lower Pliocene Productive Series

Springer Geology, 2014
This 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 ...

Thematic Set: Scaling in stratigraphic data series: implications for practical stratigraphy

First Break, 2010
Sedimentary layers are planiform, lenticular, generally composite, three-dimensional bodies, distinguished by their lithologies. They are mostly defined and logged in terms of their thickness. This parameter relates non-linearly to time, since it is the outcome of both deposition (at various instantaneous rates) and erosion, which jointly influence the

The stratigraphy of the arenig series in the Aberdaron to Sarn Area, Western Llŷcn, North Wales

Geological Journal, 1988
AbstractA new interpretation of the Arenig succession in the Aberdaron area is presented based on biostratigraphical correlation. A lithostratigraphy based on section correlation is presented, and three subareas are identified, each with a different stratigraphy.The Sarn Formation comprises the basal ‘flaggy’ sandstone unit in all three areas but is ...
