Thermophysical Properties Of Devonian Shales
SPE Annual Technical Conference and Exhibition, 1979Abstract A detailed study of the thermophysical properties of Devonian shales from the central and eastern United States has been carried out. The properties encompass a wide spectrum of material properties such as thermal conductivity, thermal diffusivity, specific heat, dielectric constant and sonic velocities ...

Summary A review of the radiometric evidence suggests that the top of the Devonian should be dated at about 345 m.y. and the base of the system at about 395 m.y. Using cumulative thickness methods the age of the base of the Upper Devonian is estimated at 358 m.y. and that of the base of the Middle Devonian at 370 m.y.

Abstract The Devonian succeeded the Caledonian orogeny, which had resulted in great changes in plate framework and tectonogeography in the world. Smith eta!. (1981), Ziegler (1981), and Scotese and McKerrow (1990) have attempted to reconstruct the Devonian palaeocontinents.

AbstractThe region described in this subchapter lies between the craton and the western edge of the carbonate platform built upon the Devonian continental shelf within one or two hundred kilometres of the continental margin. Sediments deposited west of the platform edge are described in the companion volume, “Geology of the Cordilleran Orogen in Canada”

This paper reviews the Devonian-Lower Mississippian strata of NTS areas 106 and 96 lying within Geo-mapping for Energy and Minerals (GEM) Mackenzie project area and its vicinity. These strata are usually well in excess of 1 km in non-eroded sections, cropping out extensively in the Cordillera and occurring in the subsurface of adjacent Interior Plains.
