Siliciclastic Sequence Stratigraphy—Concepts and Applications‐SEPM Series‐Concepts in Sedimentology and Paleontology #7

open access: yesEos, Transactions American Geophysical Union, 2001
Sequence stratigraphy is branch of stratigraphy that is based upon using stratal patterns and stratal termination patterns to identify groups of strata that were deposited within the same interval and therefore genetically related.

Correlations and Problems in Belt Series Stratigraphy, Northern Idaho and Western Montana

Geological Society of America Bulletin, 1963
A continuous strip of geologic maps has recently been completed along the Idaho-Montana state line between Clark Fork, Idaho, and Superior, Montana. New stratigraphic and petrographic information provides the basis for stratigraphic correlations and for the interpretation of facies changes in this part of the basin of deposition of the Precambrian Belt

The stratigraphy and origin of the portaskaig boulder bed series (Dalradian) [PDF]

open access: yesGeological Journal, 1964
AbstractThe late Pre‐Cambrian Portaskaig Boulder Bed Series shows a very uniform sequence for some 600 km along the Caledonian strike, from Connemara on the west coast of Ireland to Aberdeenshire in Scotland. The Series, which is divided into four groups of beds, comprises numerous individual boulder beds separated by stratified sediments.

High resolution trilobite stratigraphy of the Lower–Middle Ordovician Öland Series of Baltoscandia

Geological Magazine, 2012
AbstractThe first ever list of the regional Öland Series (Tremadocian to mid Darriwilian) trilobites and agnostids from the whole of Baltoscandia is compiled. The study includes revision of systematics as well as vertical and horizontal distribution. This is necessary because of the uneven state of knowledge, some faunas having being studied recently ...

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

Sequence stratigraphy and coal accumulation of Lower Cretaceous coal-bearing series in Erlian Basin, northeastern China

American Association of Petroleum Geologists Bulletin, 2019
The detailed depositional systems and basin evolution of Lower Cretaceous coal-bearing strata in the Erlian Basin of northeastern China were analyzed based on extensive borehole and outcrop data.

Belt Series of the North: Stratigraphy, Sedimentation, Paleontology

Geological Society of America Bulletin, 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.

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.

The stratigraphy and tectonics of the Manx Slate Series, Isle of Man

Quarterly Journal of the Geological Society of London, 1963
The geosynclinal sequence of the Manx Slate Series has been subdivided into eleven distinct formations with a thickness of about 25 000 ft. This thick sedimentary pile was deposited in the Caledonian geosyncline and is most probably all of Cambrian age. The stratigraphical positions of two thick sheets of slump-breccia have been established.
