Paleomagnetism of the Upper Paleozoic of the Novaya Zemlya Archipelago
Izvestiya, Physics of the Solid Earth, 2017The rock magnetic and paleomagnetic results from the Upper Paleozoic sedimentary sequences composing the isles of the Novaya Zemlya Archipelago are presented. The recorded temperature dependences of the magnetic susceptibility, the magnetic hysteresis parameters, and the results of the first-order reversal curve (FORC) measurements suggest the presence

UPPER-PALEOZOIC BIOMORPHIC SILICITES IN GORNY TAIMYR
Russian Geology and Geophysics, 1992Spongolites, biomorphic siliceous rocks, have been distinguished in the Upper Paleozoic deposits of the Taimyr fold system. for the first time. Both spongolites themselves and enclosing rocks are lithologically specified in detail. The regular position of siliceous rocks is shown to fix a period of sedimentation “starvation” in the history of the ...

Upper Paleozoic Development of Nashville Dome, Tennessee
AAPG Bulletin, 1936ABSTRACT An isopach map showing the distribution and thickness of the New Providence shale, a structure-contour map on the Chattanooga shale, and a section across central Tennessee have been prepared to illustrate the stratigraphy and structure of the Nashville dome. The dome is shown to have been developed synchronously with mountain-

Marine Upper Paleozoic Deposits of Arctic: ABSTRACT
AAPG Bulletin, 1970Marine upper Paleozoic deposits within the Arctic are widespread in Novaya Zemlya, the Pechora basin, Taimyr, the Verkhoyansk basin, northeastern USSR, Spitsbergen, Greenland, the Arctic Archipelago of Canada, and Alaska. The upper Paleozoic in all these regions includes not only Permian, but also widespread middle-Upper Carboniferous deposits. Fossils

Paleozoic and associated rocks of the Upper Yukon, Alaska
Geological Society of America Bulletin, 1908Geography The province here to be considered embraces that part of the Alaska-Yukon basin lying adjacent to the International boundary (141st meridian) and stretching westward to the 152d meridian. The Tanana river can be regarded as its southern boundary, and it extends northward to about the 67th parallel of latitude.

First discovery of Phyllospondyli in upper Paleozoic of Kazakhstan
International Geology Review, 1965A collection of small amphibian fossils (Pelosaurus laticeps Credner) is reported from fine-grained sandstones and siltstones 130 km north of Alma Ata on the left bank of the Kurtinka river, Kazakhstan. P. laticeps is also known from lower Permian beds in Germany and France, and its identification permits the dating of the Kurtinka beds as lower ...

Summary of Russian Papers on Upper Paleozoic Reefs
The Journal of Geology, 1950Several recent short papers on Upper Paleozoic carbonate reefs in the Ural Mountains and North Russian Plains are summarized. Reef migration and relation to tectonic activity, petrographic features and dolomitization of the Ishimbaevo oil-bearing massifs, and lithology of small reefs exposed on the North Russian Plain are described briefly.

UPPER PALEOZOIC OF WESTERN AUSTRALIA: CORRELATION AND PALEOGEOGRAPHY
AAPG Bulletin, 1941ABSTRACT The paper reviews the upper Paleozoic rocks in the three most important districts of Western Australia: Irwin River, North-West Division, and West Kimberley Division. The strata and their fossils are described in broad outline and a correlation between the three sequences is suggested.

Preface to Upper Paleozoic stratigraphy of the southwest United States
Stratigraphy, 2015This volume targets two areas of the American Southwest: the Guadalupe Mountains and Delaware basin, Texas, and the southern Inyo Mountains, California. In Texas, detailed lithostratigraphy of a complete section of the latest Guadalupian Reef Trail Member of the Bell Canyon Formation is presented for a better framework to study late Guadalupian events.

Silica in Sediments of the Upper Paleozoic of the Cordilleran Area
1959Abstract Sedimentation during the Upper Paleozoic in the Cordilleran geosyncline involved the introduction and incorporation of tremendous quantities of siliceous materials within the limestone, orthoquartzite, and shale sequence. The repository had the characteristics of a miogeosyncline, yet chert is abundantly represented among the
