A paleomagnetic reinvestigation of the Upper Devonian Perry Formation: evidence for Late Paleozoic remagnetization
In view of the recent recognition of widespread Late Paleozoic remagnetization of Devonian formations across North America, we undertook a reinvestigation of the Upper Devonian Perry Formation of coastal Maine and adjacent New Brunswick. Thermal demagnetization of samples from the redbeds yielded a characteristic direction (D = 166 ° l = 4 ° ) that fails a fold test. Comparison of the correspon...
متن کاملPaleomagnetic results from the Lower Devonian Llandstadwell Formation, Dyfed, Wales
Steams, C. and Van der Voo, R., 1987. Paleomagnetic results from the Lower Devonian Llandstadwell Formation, Dyfed, Wales. Tectonophysics, 143: 329-334. A paleomagnetic investigation of the Lower Devonian Llandstadwell Eormation in southwest Wales has yielded a characteristic direction (declination = 196’. inclination = 5’) that passes a fold test. Comparison of the corresponding virtual geomag...
متن کاملMicrobial life in the late Paleozoic: new discoveries from the Early Devonian and Carboniferous
Fungal spores from the Lower Devonian Rhynie Chert are known to harbor a wide variety of parasitic and saprotrophic microfungi. However, only a few of these intrusive organisms have been documented in detail. This paper describes a previously unknown microfungus contained in fungal spores from the Rhynie chert; it consists of tenuous branched filaments and terminal, globose, usually apophysate ...
متن کاملUPPER DEVONIAN ACRITARCHS AND MIOSPORES FROM THE GEIRUD FORMATION IN CENTRAL ALBORZ RANGE, NORTHERN IRAN
The Geirud Formation consists mainly of clastic sediments which are interbedded with limestone stringers. This rock unit is well-exposed along the Central Alborz Range in northern Iran. The Geirud Formation rests unconformably on the Mila Formation (Upper Cambrian) and is conformably overlain by the Mobarak Formation (Lower Carboniferous). This study was undertaken to determine the geologi...
متن کاملPaleomagnetic Evidence for PostDevonian Displacement of the Avalon Platform Newfoundland
The possibility that the Avalon Platform, where the Avalonian lithotectonic belt is best developed, was involved in late Paleozoic displacement was tested by paleomagnetic study of red sandstones of the Upper Devonian Terrenceville Formation of eastern Newfoundland. Two magnetization directions were identified by thermal demagnetization analysis of 60 oriented samples from 10 sites: a high bloc...
