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

Strontium isotope stratigraphy of the Comanchean Series in north Texas and southern Oklahoma

Geological Society of America Bulletin, 2003
Pioneering 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 ...

The stratigraphy of the Great Estuarine Series (Middle Jurassic of the Inner Hebrides)

Transactions of the Edinburgh Geological Society, 1962
The successions in the Great Estuarine Series in Northern and Southern Skye, Raasay, Eigg, Muck, Ardnamurchan and Mull are described and correlated. The limits of the Series are defined in each area, and the evidence for its age in the standard zonal scheme is reviewed.

STRATIGRAPHY OF OCOEE SERIES, GREAT SMOKY MOUNTAINS, TENNESSEE AND NORTH CAROLINA

Geological Society of America Bulletin, 1958
Much of the Great Smoky Mountains, which span the boundary between Tennessee and North Carolina, is formed of the Ocoee series, of later Precambrian age. This is a body of terrigenous clastic sedimentary rocks, which has minor intercalations of limestone and dolomite but no volcanic components or known fossils.

Integrated stratigraphy and paleoenvironmental reconstruction of the Miocene series of the Châteauredon Dome, S.E. France

Eclogae Geologicae Helvetiae, 2006
This study presents the results of a palynological analysis (dinocysts, spores and pollen) that are discussed with those obtained from stable isotopes geochemistry (δ13C and δ18O) on Miocene coastal and continental deposits in the southern area of the Digne Valensole Basin.

Stratigraphy and structure of the Mistassini series in the Lake Albanel area.

1947
During the 1946 field season, three prospecting parties engaged by Mistassini Explorations Ltd. worked in, and northeast of, the Lake Mistassini region. The purpose was to investigate reports of lead, zinc, silver, and iron occurrences, and to outline the geology of the region as a basis for future prospecting.

Stratigraphy and Correlation of the Indravati Series (Purana Group) of Bastar Dt. (M.P.)

Journal Geological Society of India, 1963
Abstract The sequence of the Purana formations of Bastar, in the ascending order of (1) Tiratgarh subarkose and orthoquartzite, with purple shale towards the top, (2) Kanger grey laminated limestone, and (3) Jagdalpur purple shale and shale-limestone, with intercalations of quartzites and limestones, in one conformable series, is ...

Stratigraphy and deformation history of the Jurassic coal bearing series in the Eastern Mecsek (Hungary)

International Journal of Coal Geology, 2012
Abstract Based on integrated interpretation of well-log and core data of 60 fully cored deep drillings and 2D seismic profiles, sequence stratigraphic and structural development models have been elaborated for the “Maza-South–Varalja-South” coal exploration site and for the Northern Imbricates, Eastern Mecsek, SW Hungary.
