Bottom-up controls, ecological revolutions and diversification in the oceans through time by Antell, GT, Saupe, EE

“…Here, we review modern and fossil evidence for hypothesized bottom-up pathways, and we assess the ramifications of these processes for four key intervals in marine ecosystems: the Ediacaran–Cambrian (635–485 million years ago), the Ordovician (485–444 million years ago), the Devonian (419–359 million years ago) and the Mesozoic (252–66 million years ago). …”

Mass concentration of Hirnantian cephalopods from the Siljan District, Sweden; taxonomy, palaeoecology and palaeobiogeographic relationships by B. Kröger, J. O. R. Ebbestad, A. E. S. Högström, Å. M. Frisk

“…Notable is the lack of many higher taxa, that are typical for other Late Ordovician shallow water depositional settings. Based on the taxonomical composition of the cephalopod mass occurrence it is interpreted as an indicator of eutrophication of the water masses in the area. …”

Late Permian to Triassic intraplate orogeny of the southern Tianshan and adjacent regions, NW China by Wei Ju, Guiting Hou

“…The paper presents a new evolutionary model for the South Tianshan Orogen and adjacent regions, which includes seven stages: (I) late Ordovician–early Silurian opening of the South Tianshan Ocean; (II) middle Silurian–middle Devonian subduction of the South Tianshan Ocean beneath an active margin of the North Asian continent; (III) late Devonian–late Carboniferous closure of the South Tianshan Ocean and collision between the Kazakhstan-Yili and Tarim continental blocks; (IV) early Permian post-collisional magmatism and rifting; (V) late Permian–Triassic the first intraplate orogeny; (VI) Jurassic–Palaeogene tectonic stagnation and (VII) Neocene–Quaternary intraplate orogeny.…”

Origin of gas condensate reservoir in Fuman Oilfield, Tarim Basin, NW China by Qinghua WANG

“…To understand the reservoir property and hydrocarbon accumulation conditions of the Middle and Upper Ordovician intraplatform shoal between ultra-deep main strike-slip faults in Fuman Oilfield of the Tarim Basin, China, the main strike-slip faults in and around well FD1 in the basin were analyzed in terms of sedimentary facies, sequence stratigraphy, intraplatform shoal reservoir property, and oil and gas origins, based on drilling data. …”

“…Abstract Pervasive intracontinental orogenesis during the Paleozoic has been widely recognized in the metamorphic and structural records of the Aileron Province and Amadeus Basin in central Australia, commonly attributed to the Ordovician–Carboniferous Alice Springs Orogeny. Comparatively less clear, however, is the magnitude and geographic expression of this event elsewhere in the North Australian Craton. …”

60 years of the Serbo-Macedonian Unit concept: From Cadomian towards alpine tectonic frameworks by Spahić Darko, Gaudenyi Tivadar

“…However, the original early Pa - leozoic tectonostratigraphic configuration of these three intimate green schistand medium- to high-grade gneiss-amphibolite basement vestiges (Serbo-Ma - cedonian/Supragetic and Getic) is further perplexed by the presence of poorly documented pre-Variscan (Ordovician?) lithospheric-scale event. The Pan-African to Lower Paleozoic subduction/magmatic arc stage led to the amalgamation, breakup and dispersal of a cluster of peri-Gondwanan continental and oceanic terranes. …”
