“…6A). A recent detailed lithofacies analysis on the Akasaka limestone reveals that the G-LB horizon is characterized by a sea level low stand that caused an erosional hiatus (Kofukuda et al 2014). This analysis records a significant sea-level drop in the mid-superocean, in accordance with the results of sequence stratigraphy on the contemporary peri-Pangean shelf strata (Haq and Schutter 2008).…”

The information reflected in mid-oceanic sedimentary deposits provides critical constraints for reconstructing past global environmental changes. Available data from extant oceans, however, are limited to the Early Jurassic and younger ages, because older oceanic plates have been subducted. This article explains methods for obtaining information on pre-Jurassic mid-oceanic conditions by conducting fieldwork on older orogenic belts exposed on land. The key point is the identification of ancient accretionary complexes (AC), not along currently active margins but within older orogenic belts in continental domains, particularly by recognizing ocean plate stratigraphy (OPS) that contains mid-oceanic strata, as demonstrated by studies of on-land exposed ancient AC in Japan and elsewhere. In this paper, six examples of retrieved mid-oceanic sedimentary data are introduced, in which significant records on the following unique events in the pre-Jurassic world are archived: 1) the extinction-related Paleozoic–Mesozoic boundary superanoxia (based on data from the Jurassic AC in SW Japan); 2) the Permian Kamura cooling event in the mid-Panthalassa (ditto); 3) the Neoproterozoic snowball Earth evidence from the mid-Iapetus Ocean (based on data from the Neoproterozoic–Cambrian AC in Wales, UK); 4) the discovery of enigmatic Ediacaran (Neoproterozoic) microfossils from a mid-oceanic atoll complex (based on data from the Cambrian AC in southern Siberia, Russia); and 5) and 6) Early Archean (3.8 and 3.5 Ga) biogenic signatures in mid-oceanic deep-sea environments (based on data from the Eoarchean AC at Isua in Greenland, and the Paleoarchean one in Pilbara, Western Australia). These results demonstrate the great utility of OPS analysis for understanding pre-Jurassic lost oceans, including the early biological and environmental evolution of the globe. SOMMAIRELes informations enregistrées dans les dépôts sédimentaires médio-océaniques constituent des contraintes logiques qui permettent de reconstituer les changements environnementaux globaux. Cela dit, l’information sur de grands pans de fonds océaniques est limitée aux fonds océaniques Jurassiques précoces et plus jeunes, parce que les fonds océaniques plus anciens ont été subduits. Le présent article explique des méthodes permettant d’obtenir de l’information sur les milieux médio-océaniques pré-jurassiques par des levés de terrain sur des ceintures orogéniques affleurant sur terre. L’idée centrale consiste à circonscrire d’anciens complexes d’accrétion (AC), hors des marges actives actuelles, soit dans les ceintures orogéniques plus anciennes au sein des domaines continentaux, en y repérant des contextes stratigraphiques de plaques océaniques (OPS) qui renferment des strates médio-océaniques, comme ça a été fait lors études d’AC affleurant au Japon et ailleurs. Le présent document décrit six exemples de contextes stratigraphiques de plaques océaniques où on trouve des indices importants des événements pré-jurassiques uniques suivants : 1) l’extinction liée à la super-anoxie de la limite Paléozoïque-Mésozoïque (à partir des données d’un AC jurassique dans le sud-ouest du Japon); 2) l’épisode de refroidissement permien de Kamura du Panthalassa moyen; 3) l’épisode néoprotérozoïque de « Terre boule de neige » conservé par l’océan mi-japétien (selon les données de l’AC néoprotérozoïque-cambrien dans les Wales au Royaume-Uni); 4) la découverte de microfossiles édiacariens (Néoprotérozoïque) d’un complexe d’atolls médio-océaniques (selon les données d’un AC cambrien du sud-est sibérien, Russie); et 5 et 6) des signatures biogéniques de milieux médio-océaniques profonds de l’Archéen précoce (3,8 et 3,5 Ga) (selon les données d’un AC éoarchéen à Isua au Groenland, et d’un AC paléoarchéen à Pilbara, Australie). Ces résultats montrent la grande utilité de l'analyse de la stratigraphie des plaques océaniques pour comprendre les océans pré-Jurassique, de même que l'évolution des débuts de la vie et des milieux de vie sur Terre.

The so‐called Big Five mass extinctions of the Phanerozoic include two prominent Palaeozoic episodes: the end‐Ordovician and end‐Permian events, both with large biodiversity loss. We consider that the end‐Ordovician (Hirnantian) extinction could be best compared to the Middle Permian end‐Guadalupian (=Capitanian) extinction, rather than to the end‐Permian (Permo‐Triassic boundary; PTB) extinction. The end‐Guadalupian extinction, ca. 8 Myr before the PTB extinction, occurred as an independent episode under extremely unique global setting with the lowest sea level and lowest Sr isotopic ratios in seawater of the Phanerozoic. Multiple similarities exist between the end‐Ordovician (Hirnantian) and the end‐Guadalupian (Capitanian) events, such as the preferential elimination of sessile biota in the tropics, a global sea‐level drop and secular changes in seawater C and Sr isotope ratios, occurring under global cooling. The limited development of land vegetation suggests that the Ordovician extinction was restricted solely to the marine realm, with no prominent damages on land, and no large igneous province (LIP) recognized in the Ordovician. The comparison indicates that the two extinctions of the Hirnantian and of the Capitanian have been essentially triggered by similar causes/processes; nonetheless, biotic responses were different, owing to the more oxygenated status of surface environments in the Permian after the mid‐Palaeozoic terrestrialization.

“…The abundance of frondose bryozoans, alatoconchid bivalves, and last large fusulinids in the carbonate successions of the unit VII is very similar to preextinction communities of the Late Capitanian (Wood 1998;Kofukuda et al 2014). The first appearance of Clarkina postbitteri postbitteri is not recorded yet in the section.…”

Micropaleontological investigations on Permian successions in the NW of Iran based on algae led to the determination of taxa belonging to some families such as Ungdarellaceae (Ungdarella uralica), Gymnocodiaceae (Gymnocodium bellerophontis and Permocalculus sp.), D a s y c l a d a l e s ( M i z z i a c f . M . y a b e i ) , a n d s o m e microproblematics (Vermiporella nipponica and Pseudovermiporella sodalica). These investigations are mainly focused on the Khachik Formation at the Ali Bashi Mountains. According to the algal community, a lagoon environment is offered for the studied successions.
