Igneous and sedimentary ‘limestones’: the puzzling challenge of a converging classification
Abstract The vast majority of extrusive carbonatites are calcitic rocks which may be confused with sedimentary limestones, thus requiring a disambiguation criterion. Extrusive carbonatites are classified based on quantitative criteria that tend to avoid genetic mechanisms. Carbonatite nomenclature is in progress but regulated by the International Union of Geological Sciences norm for igneous rocks. Carbonate sedimentary rock nomenclature is mainly regulated by the Dunham, Embry and Klovan, and Sibley and Gregg classification systems. These limit the description of rock types from various depositional mechanisms and makes comparison with sedimentary rocks difficult. Igneous and sedimentary carbonate rocks display no apparent differences in the field and at meso–micro-scale. They may be layered, massive crystalline or show discrete clasts in a matrix, which make both rock types resemble one another. The study analyses the situations in which classification inconsistencies are most common. Adopting these guidelines may increase confidence, reliability and value in the petrographic classification of igneous and sedimentary lithologies. This study poses a challenging target. Can igneous carbonate rocks be classified using the same approach that is used for sedimentary carbonate rocks and vice versa? So far, the scheme chosen has been arbitrary or limited to the aim of the study being undertaken. The authors start an unexperienced dialogue for the first time between volcanologists and sedimentologists by examining a range of sedimentary and volcaniclastic rock textures which may resemble each other.

Upper Triassic–lowermost Jurassic palynology and palynostratigraphy: a review
Abstract This review advances understanding of the palynostratigraphy of the Late Triassic–Early Jurassic by correlating the established palynozonations for the northern and southern hemispheres. Previous palynological studies have contributed greatly to our understanding of the biostratigraphy, paleoclimatology and paleogeography of the Upper Triassic. In general, palynology is a good tool for interregional cross-correlation of marine and non-marine successions because palynomorphs, unlike most of other fossils, commonly are present in continental and marine environments. Currently, however, biostratigraphical resolution based on Upper Triassic palynomorph assemblages is rather low, primarily because of the rarity of successions that are independently dated (i.e. via ammonoids, conodonts, isotopes, paleomagnetism) to correlate the palynomorph assemblages, but also for other reasons, such as microfloristic provincialism, palaeoenvironmental conditions and differential preservation of palynomorph assemblages. During the last few decades many palynological studies have attempted to integrate and improve the biostratigraphical correlations and paleoclimatologic reconstructions across the Triassic–Jurassic boundary. Several authors have recognized specific microfloral assemblages with well-defined and recognizable suites of palynomorphs that enhance the importance of palynomorphs in the definition of Triassic–Jurassic stages. Comparison of the palynomorph assemblages from different biostratigraphical stages demonstrates that a change occurred in the palynofloral composition of the Tethyan domain between the Carnian and the earliest Hettangian that was gradual and without abrupt changes.
