Late Silurian palynomorphs from the Precordillera of San Juan, Argentina: Diversity, palaeoenvironmental and palaeogeographic significance
The palynological content from the Cerro La Chilca and Quebrada Ancha sections of the Wenlock? to Přídolí Los Espejos Formation, in the Argentinean Precordillera is studied. The marine palynomorphs exhibit higher relative abundance and diversity in almost all the productive samples, except for the uppermost ones from both sections, in coincidence with the shift towards more proximal facies in t...
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 کاملThe Botrychiopsis genus and its biostratigraphic implications in Southern Paraná Basin.
Botrychiopsis has been considered an important floristic element of Westphalian/Artinskian associations of the Paraná Basin. The occurrence of Botrychiopsis in roof-shales of the Rio Bonito Formation in Southern Paraná Basin (Quitéria area), supported by the identification of Botrychiopsis valida, enlarges the genus biochron. Consequently, the stratigraphic hierarchy for Botrychiopsis plantiana...
متن کاملKatbergia Gen. Nov., a New Trace Fossil from Upper Permian and Lower Triassic Rocks of the Karoo Basin: Implications for Palaeoenvironmental Conditions at the P ⁄tr Extinction Event
A new ichnogenus and ichnospecies of burrow, Katbergia carltonichnus, are described from Upper Permian and Lower Triassic rocks of the Karoo Basin, South Africa, where they are preserved in pedogenically modified overbank deposits that are interpreted as inceptisols subsequently gleysol overprinted. Sigmoidal burrows consist of a long (‡0.5 m) cylindrical tube, ranging from 1–2 cm in diameter, ...
متن کاملCharcoals from the Past: Cultural and Palaeoenvironmental Implications
It has been suggested that climates during the Holocene have varied on timescales of about 1500 years, forced by oscillations of a solar cycle. These climatic changes have been implicated as the cause of changes in geological records from, mostly, marine sediments. If there were such changes, and if they were of great enough amplitude to force changes in marine sedimentation, it would be reason...
