“…A combination of a reduction in carbonate accumulation rates, through a change from oligo-to meso-trophic conditions (e.g., Brandano et al 2016), and submergence through relative sea-level rise attributed to extensional tectonics, is interpreted to be responsible for the demise of the New Guinea Limestone platform (e.g., Hallock and Schlager 1986;Sattler et al 2009). Evidence for submergence is recorded as a gradual increase in bathymetry from environmental preferences of foraminifera, either through short-term high-amplitude oscillations in the global glacioeustatic sea-level trend or localized tectonic subsidence.…”

“…The concept of drowning unconformities is well established and there are many examples of carbonate platform drowning strata documented in the rock record worldwide (e.g., Schlager 1981Schlager , 1989Hallock and Schlager 1986;Longman et al 1987;Simone and Carannante 1988;Erlich et al 1990Erlich et al , 1993Föllmi et al 1994;Drzewiecki and Simo 1997;Weissert et al 1998;Blomeier and Reijmer 1999;Wortmann and Weissert 2000;Wissler et al 2003;Ruiz-Ortiz et al 2004;Mutti et al 2005;Föllmi and Gainon 2008;Sattler et al 2009;Najarro et al 2011;Marino and Santantonio 2010;Brandano et al 2016;Sulli and Interbartolo 2016). Carbonate platforms are defined as flat-topped accumulations of carbonate sediments developed at or very near sea level (Hallock and Schlager 1986).…”

“…In all cases, however, platform drowning occurs because the rate of platform top production and accumulation is exceeded by the rate of relative sea-level rise, either because the rate of relative sea-level rise has increased, or because the rate of carbonate production has decreased. The process of carbonate platform drowning presents somewhat of a paradox as rates of carbonate production and accumulation normally exceed rates of long-term sea-level rise and subsidence; glacioeustatic sea-level rises, on the other hand, can exceed carbonate production (Schlager 1981;Hallock and Schlager 1986;Föllmi et al 1994;Wissler et al 2003;Ruiz-Ortiz et al 2004;Mutti et al 2005;Brandano et al 2016). Kim et al (2012) demonstrated that even if the rate of relative-sea level rise is lower than maximum carbonate potential platform drowning can still occur if accumulation rates at the initiation of drowning are lower than the rate of relative sea-level rise.…”

environment. Already foundering carbonate platforms due to environmental deterioration were left vulnerable to submergence and eventually succumbed to drowning. Low rates of carbonate production were outpaced by the rate of relative sea-level rise caused by high-amplitude oscillations in global glacio-eustatic sea-level change and/or regional tectonic subsidence. The duration of the drowning event across the entire Bird's Head region is interpreted to have lasted a duration of approximately 9.5 My, between 18.0 and 8.58 Ma. This has implications when interpreting timings of sedimentary basin fill across western New Guinea and in other basins where carbonate platform drowning is recorded.

“…The Polino diatreme crosses the Calcare Massiccio Formation, a Lower Jurassic peritidal carbonate succession cropping out in the Apennines originally deposited along the passive margin of the Adria micro-plate (e.g., ref. 60 ). During two campaigns in 2016 and 2017, twelve samples were collected and analysed for petrographic investigation using the polarizing microscope, scanning electron microscopy (SEM) and electron microprobe (EMP), while three of them have been analyzed for major oxides (ICP-AES) and trace elements (ICP-MS) at the Activation Laboratories (Ontario, Canada).…”

The small upper Pleistocene diatreme of Polino (central Italy) is known in literature as one of the few monticellite alvikites (volcanic Ca-carbonatite) worldwide. This outcrop belongs to the Umbria-Latium Ultra-alkaline District (ULUD), an area characterized by scattered and small-volume strongly SiO 2 -undersaturated ultrabasic igneous rocks located in the axial sector of the Apennine Mts. in central Italy. Petrographic and mineralogical evidences indicate that Polino olivine and phlogopite are liquidus phases rather than mantle xenocrysts as instead reported in literature. The presence of monticellite as rim of olivine phenocrysts and as groundmass phase indicates its late appearance in magma chambers at shallow depths, as demonstrated by experimental studies too. The absence of plagioclase and clinopyroxene along with the extremely MgO-rich composition of olivine (Fo 92–94 ) and phlogopite (average Mg# ~93) suggest for Polino magmas an origin from a carbonated H 2 O-bearing mantle source at depths at least of 90–100 km, in the magnesite stability field. In contrast with what reported in literature, the ultimate strongly ultrabasic Ca-rich whole-rock composition (~15–25 wt% SiO 2 , ~31–40 wt% CaO) and the abundant modal groundmass calcite are not pristine features of Polino magma. We propose that the observed mineral assemblage and whole-rock compositions result mostly from the assimilation of limestones by an ultrabasic melt at a depth of ~5 km. A reaction involving liquidus olivine + limestone producing monticellite + CO 2 vapour + calcite is at the base of the origin of the Polino pseudocarbonatitic igneous rocks.

“…During the Late Triassic, the rifting of the Tethys led to a marine transgression, testified by the evaporitic deposition of the Anidridi di Burano and, subsequently, by the development of the Calcare Massiccio carbonate platform (Pialli, 1971). During the Early Jurassic, the Calcare Massiccio platform drowned due to the rift-related extensional tectonics, and the Umbria-Marche domain evolved into a wide basin characterised by intrabasinal structural highs (Centamore et al, 1971;Bernoulli and Jenkyns, 1974;Brandano et al, 2016b) until the Late Jurassic.…”

The Eocene-Oligocene transition marks a fundamental step in the evolution of the modern climate. This climate change and the consequent major oceanic reorganisation affected the global carbon cycle, whose dynamics across this crucial interval are far from being clearly understood. In this work, the upper Eocene to lower Oligocene δ 13 C Carb and δ 13 C TOC records of a shallow-water and a hemipelagic carbonate settings within the Central Mediterranean area have been studied and discussed. The shallow-water carbon isotope signal has been analysed in the northern portion of the Apula Platform, cropping out in the Majella Mountain, Central Apennines (Santo Spirito Formation). A coeval Umbria-Marche basinal succession has been investigated in the Massignano section (Conero area, Central Italy). The purposes of this work are: to discriminate between the global and the local (Mediterranean) signature of C-isotope record during the Oi-1 event, to correlate the regional C-isotope signal with the global record, and to evaluate the carbon cycle dynamics across the greenhouse-icehouse transition through the integration of complementary records (shallow-water vs pelagic settings, δ 13 C Carb vs δ 13 C TOC). The upper Eocene carbon isotope record of the analysed successions matches with the global signal. The overall trend shows a decrease of the δ 13 C Carb and a contemporary increase of the δ 13 C TOC. The decoupling of the two curves is consistent with a reduced fractionation effect by primary producers that characterised the interval between the Middle Eocene Climatic Optimum and the onset of the Oi-1 event. However, regional factors superimposed the global signal. In fact, the upper Eocene basinal δ 13 C TOC record is marked by short-term negative spikes, which possibly represent times of higher productivity triggered by the westward subtropical Eocene Neotethys current entering from the Arabian-Eurasian gateway. On the contrary, the shallow-water record does not display these short-term productivity pulses. A change in the carbonate factory is only recorded at the Eocene-Oligocene transition, marked by a reduction of the larger benthic foraminifera and the spread of seagrass and corals. Moreover, in the shallow-water record of the Santo Spirito Formation, no major carbon isotope shift related to the Oi-1 event is recorded due to the presence of extensive slumps that disrupt the bedding. These slumps are the main evidence of the sea-level drop that occurred concomitantly with the onset of the Antarctica ice-sheet, which caused the deepening of the storm wave base and increased the instability over the entire ramp.
