CAIROELLA TRICAMERATA N. GEN., N. SP. (FORAMINIFERIDA, MILIOLOIDEA) FROM THE LOWER CENOMANIAN OF MONTE CAIRO (SOUTHERN LATIUM, CENTRAL ITALY)

A new porcelaneous foraminifer, Cairoella tricamerata n. gen., n. sp., is here described from the lower Cenomanian of the Monte Cairo area near Cassino (Southern Latium, Italy). The new taxon is characterized by an early stage with triloculine to quinqueloculine coiling, followed by one or two whorls, each consisting of three or more tubular, curved, flattened and undivided chambers, with depressed sutures; it is ascribed  to the superfamily Milioloidea, but the inferred  attribution to the family Hauerinidae remains uncertain. In the type-locality its occurrence is restricted to the back-edge facies of the Latium-Abruzzi carbonate platform represented by fossiliferous grain-supported limestone rich in Sellialveolina viallii Colalongo, 1963

PALEOCENE TO LOWER EOCENE LARGER FORAMINIFERAL ASSEMBLAGES FROM CENTRAL ITALY: NEW REMARKS ON BIOSTRATIGRAPHY

We present the micropaleontological record on ongoing research on Paleogene larger foraminifers from Central Italy collected in the field work for the realization of the geological sheet 348 “Antrodoco” of the Geological Map of Italy 1:50.000 scale. The work provides an examination of the biostratigraphic potential of selected taxa with emphasis on rotaliids. Ornatorotalia is documented for the first time from the Paleocene. Possible new species of Miscellanea, Ornatorotalia, and Rotalia are figured and described in open nomenclature

Calcarenites in the upper Miocene terrigenous units of Central Apennines: Composition, age and paleogeographic significance

[No abstract available

Carbonate intercalations in a terrigenous foredeep: Late Miocene examples from the Simbruini Mts. and the Salto Valley (Central Apennines -Italy)

Resedimented calcarenites and hybrid arenites are commonly found interbedded with various Upper Miocene terrigenous units (hemipelagic marls, "brecce della Renga fm.", and siliciclastic turbidites) across the Simbruini Mts. and neighbouring areas of Central Apennines. Their distribution provides evidence for a complex, and rapidly evolving, paleogeography across a region that was experiencing the transition from foreland to accretionary wedge conditions during the Tortonian and Messinian. The bio-sedimentological features of the calcarenites indicate deposition through gravity flows (turbidity currents) sourced by areas of active benthic, heterozoan-type carbonate production, locally lying at photic depth. Thin-section analysis of >130 samples revealed that the resedimented levels are mainly composed by bioclastic calcarenites, with fragments of bivalves, echinoids, bryozoans, balanids, benthic foraminifera, anellids and red algae, along with subordinate planktonic foraminifera. The calcareous turbidites in the hemipelagic marls (Unita argillosomarnosa) are characterized by the presence of Heterostegina sp., and their main source area was probably lying east, on the undeformed foreland. In contrast, evidence from field mapping, their common association with Cretaceous and Miocene carbonate lithoclasts, and the age of the encasing units, all suggest that the calcarenites in the "brecce della Renga fm." and in the siliciclastic turbidites ("complesso torbiditico altomiocenico laziale-abruzzese") could most likely have a different source. The presence of a carbonate ridge, corresponding today to the NW sector of the Simbruini range, bordered by normal faults exposing the Cretaceous substrate, is proven proven by mappable paleoescarpment tracts onlapped by clastic and hemipelagic deposits. This ridge could have fed surrounding deeper areas with a mixture of lithoclasts and loose bioclastic material, produced through erosion of exposed bedrock coupled with export of sediment that was being produced topping and fringing the footwall blocks and their marginal downsteps. Carbonate production was apparently able to survive for a limited time in small productive areas until the early Messinian, shedding sediment into the siliciclastic foredeep

La Carta geologica del Parco Naturale Regionale dei Monti Simbruini.

<p>Il Parco Naturale Regionale dei Monti Simbruini rappresenta la più vasta area protetta del Lazio, è estesa su un territorio di 29.990 ettari tra le province di Roma e Frosinone.</p><p>A seguito di un accordo di convenzione tra l'ISPRA e l'Ente Parco, nel 2019 è stata realizzata la "Carta geologica del Parco Naturale dei Monti Simbruini", alla scala di 1:35.000.</p><p>Questa presentazione illustra i motivi, le modalità e la procedura utilizzata per la realizzazione di questo prodotto cartografico originale, le cui finalità sono quelle di diffondere le conoscenze geologiche acquisite dai ricercatori dell'ISPRA a stakeholder non specialisti: insegnanti di scienze, studenti, escursionisti.</p><p> </p&gt
