    Based on seven measured sections from Svalbard, the marine strata of the Permian Kapp Starostin Formation are arranged into seven transgressive–regressive sequences (TR1–TR7) of c. 4–5 Ma average duration, each bound by a maximum regressive surface. Facies, including heterozoan-dominated limestones, spiculitic cherts, sandstones, siltstones and shales, record deposition within inner, middle and outer shelf areas. The lowermost sequence, TR1, comprises most of the basal Vøringen Member, which records a transgression across the Gipshuken Formation following a hiatus of unknown duration. Temperate to cold, storm-dominated facies established in inner to middle shelf areas between the latest Artinskian and Kungurian. Prolonged deepening during sequences TR2 and TR3 was succeeded by a long-term shallowing-upward trend that lasted until the latest Permian (TR4–TR7). A major depocentre existed in central and western Spitsbergen while to the north, Dickson Land remained a shallow platform, leading to a shallow homoclinal ramp in NE Spitsbergen and Nordaustlandet. The Middle Permian extinction (late Capitanian) is recorded near the base of TR6 in deeper parts of the basin only; elsewhere this sequence is not recorded. Likewise the youngest sequence, TR7, extending to the upper formational contact of latest Permian age, is found only in the basin depocentre. Comparison with age-equivalent strata in the Sverdrup Basin of Canada reveals a remarkably similar depositional history, with, for example, two (third-order) sea-level cycles recorded in the Late Permian of both regions, in keeping with the global record. Sequence stratigraphy may therefore be a powerful correlative tool for onshore and offshore Permian deposits across NW Pangaea

    Functions of Freedom -- Privacy, Autonomy, Dignity, and the Transnational Legal Process

    No full text
    What is the function of freedom for the transnational legal process? This Article answers this question through the lens of the ongoing Ukrainian crisis and the deeply inconsistent international legal arguments presented by each side of the conflict. These inconsistencies suggest that criticism of international law as purely political pretense has merits. The Article shows that transnational legal process theory can account for and incorporate these facial inconsistencies and thus address the criticism leveled at international law. The Article proceeds to develop a theory of freedom as a value that is internal to, and necessary for, transnational legal process. This theory of freedom relies not upon the classical liberal understanding of freedom as positive or negative freedom. Instead, it reconstructs freedom around the value of human dignity. The Article concludes that freedom as dignity is a central value of the transnational legal process and that the transnational legal process would cease to function in its absence
