Benthic foraminifera distribution and diversity in inner and outer lagoonal sediments of the UAE (United Arab Emirates)

Flavia Fiorini Stephen W. Lokier Yuzhu Ge Chelsea Pederson Adrian Immenhauser

Live and dead benthic foraminifera assemblages were studied from 50 samples collected in a lagoon located between Yas Island and Ras al Gurhab Island (UAE) in a system dominated by carbonate sedimentation.Living and dead foraminifera tests are present at all of the sampled locations. The foraminifera assemblage is dominated by a high diversity of miliolidae together with epiphytic larger benthic foraminifera belonging to the genera Peneroplis, Spirolina and Sorites. Hyaline foraminifera, such as Ammonia and Elphidium, are commonly found at all the locations while agglutinated foraminifera are uncommon and have a scattered occurrence.The abundance and diversity of benthic foraminifera were calculated for each sample. Four benthic foraminifera ecological indices were applied to the studied samples. For each of the samples we calculated: the total foraminiferal number (number of foraminifera in 1 g of sediment >125 &#956;m); the percentages of agglutinated, porcellaneous and hyaline foraminifera tests; the ratio between living and dead benthic foraminifera; the ratio between larger benthic foraminifera with normal and abnormal test growth. The above-mentioned data have been applied to construct a foraminiferal assemblage database that facilitates the discrimination between inner and outer lagoonal environments.

Benthic foraminiferal associations from Upper Quaternary deposits of southeastern Po Plain, Italy

Micropaleontology (2004)

Flavia Fiorini

Quantitative analysis of benthic foraminifers from three continuously-cored boreholes (130m deep) at different distances from the Adriatic coast and focused within two marine intervals (0–30m and 100–120m depth) that on the basis of AMS 14C dating and pollen data are assigned to oxygen isotope Stage 1 and Substage 5e, respectively, has revealed seven foraminiferal associations. Associations Me (Textularia spp. and Miliolidae) and Md (Miliolidae, Elphidium spp. and Cribroelphidium spp.) are characteristic of infralittoral environments. Associations Mb (Ammonia tepida, A. parkinsoniana and Cribroelphidium spp.) and Ma (Ammonia tepida and A. parkinsoniana) are indicative of shallow-marine environments influenced by freshwater. Reworked and transported microfaunal association Rm corresponds to supralittoral environments (beach-ridge deposits). Associations Bd-b (Ammonia tepida, A. parkinsoniana and brackish ostracods) and Ba (Trochammina inflata) are characteristic of bay, lagoon and estuary environments.Comparison of benthic foraminiferal associations from coeval deposits provides information on the relative distance of cores from the Holocene and Tyrrhenian paleo-shorelines. Core 205-S10 is characterised by deeper marine associations than core 223-S12. Core 240-S13 contains exclusively associations characteristic of lagoonal and brackish marsh environments.Vertical variation in microfaunal associations within each marine deposit reveal in both intervals a transgressive trend, followed upwards by a regressive trend. Benthic foraminiferal associations from cores 205-S10 and 223-S12 show that the Tyrrhenian maximum flooding surface corresponds to a deeper marine environment than peak transgression in the Holocene. This is also shown by core 240-S13, where an open lagoonal microfauna characterizes Tyrrhenian deposits and a brackish marsh association marks the Holocene sediments.

PALEOENVIRONMENTAL RECONSTRUCTION OF THE OLIGOCENE- MIOCENE DEPOSITS OF SOUTHERN CARIBBEAN (CARMEN DE BOLIVAR, COLOMBIA) BASED ON BENTHIC FORAMINIFERA

BOLETÍN DE GEOLOGÍA (2007)

Flavia Fiorini Carlos Jaramillo

The benthic foraminifera from an Oligocene-Middle Miocene stratigraphic section were used to interpret the depositional environments of these sediments. The examined stratigraphic section (Carmen de Bolivar section) located on the arroyo Alferez (Colombia) is 1950 m long and mainly consists of shale and siltstone with sandstone layers belonging to the Carmen Formation, Oligocene-Middle Miocene in age. Paleobathymetric and paleoenvironmental interpretation were based on the foraminiferal analysis of 80 samples collected every 10-15 meters along the entire length of the section. This study shows the results of a quantitative analysis of the benthic foraminifera greater than 63µm. Several foraminiferal associations have been individuated within the section: • Associations dominated by planktic foraminifera with variable percentages of benthic foraminifera either calcareous or agglutinated. These associations are interpreted as belonging to marine environment from the upper bathyal zone. • Association dominated or totally composed by agglutinated foraminifera. The calcareous foraminifera within this association are rare and poorly preserved. The agglutinated foraminifera are abundant, finely to middle agglutinated and mainly small-sized (>63-125 µm). This association indicates a turbid water condition and suggests a organic-rich upper-middle bathyal depositional environment.
