Abstract. The North Pamir, part of the western syntax India–Asia collision zone, preserves remnants a poorly understood Paleozoic intra-oceanic subduction zone. To constrain age this ancient ocean floor, we analyzed calcite phases in vesicular basalt and basaltic volcanic breccia with U–Pb geochronology using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Dating radial...

The Lower Carboniferous (Visean) Granton Lagerstätte (Edinburgh, Scotland) is principally known for the discovery of the conodont animal, but has also yielded numerous crustaceans and other faunas. Here we report on small branching colonies, reaching 10 mm in length. They are small, erect, arborescent, and irregularly branched with predominant monopodial and dichotomous growth. They bud in a si...

Crowns of four crinoid species, Talarocrinus planus Weller, 1920, Phacelocrinus longidactylus (McChesney, 1860), Ampelocrinus mundus? Kirk, 1942, and Phanocrinus maniformis (Yandell and Shumard, 1847) are reported from the limestones of the Wymps Gap Member of the Greenbrier Formation in northern West Virginia. Collectively these species indicate an early Chesterian age for the Wymps Gap Member...


 As a result of the study core material 540 thin sections from boreholes northern marginal part and paraxial Dnieper-Donetsk Depression (DDD), complex fossil red calcareous algae including 14 species 7 genera, as well 2 belonging to genera identified for first time Visean deposits DDD has been discovered. The studied carbonate represent Hlybokynskyi, Sukhynskyi, Stylskyi, Donetskyi lower ...

The Pre-Mesozoic units exposed in the inner Northern Apennines mostly consist of Pennsylvanian-Permian successions unconformably deposited on a continental crust consolidated at end Variscan orogenic cycle (Silurian-Carboniferous). In Apennines, exposures this crust, Cambrian?-Devonian age, have been described Tuscany, Elba Island (Tuscan Archipelago) and, partly, scattered and isolated outcrop...

The paper discusses the details of application method fluid substitution which is used for predicting elastic properties reservoir rocks and their dependence on pore porosity. This makes it possible to predict changes in response a rock saturation with different fluids. main task this was study productive zones visean deposits Yablunivske field using example single well. integration petrophysic...

The paper focuses on the taxonomic description of lower Carboniferous (uppermost Tournaisian to middle Visean) solitary rugose corals from bedded limestone and shale units in Flett Formation Jackfish Gap (eastern Liard Range), northwestern Canada. described herein include 12 species representing the genera Ankhelasma Sando, 1961, Bradyphyllum Grabau, 1928, Caninophyllum Lewis, 1929, Cyathaxonia...
