“…In the Gulf, sediments and their characteristics generally follow distributions that align with the northwest-southeast axis of the Gulf (Wagner and van der Togt, 1973). The predominance of sand in the coastal regions, which are closer to the shore, and shallow in nature, can be attributed to the water circulation prevalent in this area.…”

Macrobenthic Community Structure in the Northwestern Arabian Gulf, Twelve Years after the 1991 Oil Spill

The biota in the Arabian Gulf faces stress both from natural (i.e., hyper salinity and high sea surface temperature), and human (i.e., from oil-related activities) sources. The western Arabian Gulf was also impacted by world's largest oil spill (1991 Oil Spill). However, benthic research in this region is scarce and most of the studies have been conducted only in small areas. Here, we present data on macrobenthos collected during [2002][2003] from the open waters and inner bays in the northwestern Arabian Gulf aimed to assess the ecological status and also to evaluate the long-term impact, if any, of the 1991 Oil Spill. A total of 392 macrobenthic taxa with an average (±SE) species richness (S) of 71 ± 2, Shannon-Wiener species diversity (H ′ ) of 4.9 ± 0.1, and density of 3,181 ± 359 ind. m −2 was recorded from the open water stations. The open waters have "slightly disturbed" (according to AZTI's Marine Biotic Index, AMBI) conditions, with "good-high" (according to multivariate-AMBI, M-AMBI) ecological status indicating the absence of long-term impacts of the oil spill. Overall, 162 taxa were recorded from inner bays with average (±SE) values of S 41±9, H ′ 3.48 ± 0.39, and density 4,203 ± 1,042 ind. m −2 . The lower TPH (Total Petroleum Hydrocarbons) stations (LTS, TPH concentrations <70 mg kg −2 ) show relatively higher S, H' and density compared to the higher TPH stations (HTS, TPH concentrations ≥100 mg kg −2 ). In the inner bays, AMBI values indicate slightly disturbed conditions at all stations except one, which is moderately disturbed. M-AMBI values indicate good status at LTS, while, high, good, moderate, and poor status at HTS. The "moderately disturbed" conditions with "moderate-poor" ecological status in some locations of the inner bays specify a severe long-term impact of the oil spill.

The study of the Upper Jurassic-Lower Cretaceous deposits (Higueruelas, Villar del Arzobispo and Aldea de Cortés Formations) of the South Iberian Basin (NW Valencia, Spain) reveals new stratigraphic and sedimentological data, which have significant implications on the stratigraphic framework, depositional environments and age of these units. Moreover, these new data encourage revising the previously proposed stratigraphic correlations between the studied units and those deposited in adjacent areas of the Iberian Basin.The Higueruelas Fm was deposited in a mid-inner carbonate platform where oncolitic bars migrated by the action of storms and where oncoid production progressively decreased towards the uppermost part of the unit. The overlying Villar del Arzobispo Fm has been traditionally interpreted as an inner platform-lagoon evolving into a tidal-flat. Here it is interpreted as an inner-carbonate platform affected by storms, where oolitic shoals protected a lagoon, which had siliciclastic inputs from the continent. The Aldea de Cortés Fm has been previously interpreted as a lagoon surrounded by tidal-flats and fluvial-deltaic plains. Here it is reinterpreted as a coastal wetland where siliciclastic muddy deposits interacted with shallow fresh to marine water bodies, aeolian dunes and continental siliciclastic inputs.The contact between the Higueruelas and Villar del Arzobispo Fms, classically defined as gradual, is interpreted here as gradual and rapid, because the transition between both units comprises few meters. More importantly, the contact between the Villar del Arzobispo and Aldea de Cortés Fms, previously considered as unconformable, is here interpreted as gradual.The presence of Alveosepta in the Villar del Arzobispo Fm suggests that at least part of this unit is Kimmeridgian, unlike the previously assigned Late Tithonian-Middle Berriasian age. Consequently, the underlying Higueruelas Fm, previously considered Tithonian, should not be younger than Kimmeridgian. Accordingly, sedimentation of the Aldea de Cortés Fm, previously considered Valanginian-Hauterivian, probably started during the Tithonian and it may be considered part of the regressive trend of the Late Jurassic-Early Cretaceous cycle. This is consistent with the dinosaur faunas, typically Jurassic, described in the Villar del Arzobispo and Aldea de Cortés Fms Keywords: Mixed carbonate-siliciclastic platform, coastal wetland, Foraminifera, Spain, Kimmeridgian, Tithonian Resumen El estudio de los depósitos del Jurásico Superior-Cretácico Inferior (formaciones Higueruelas, Villar del Arzobispo y Aldea de Cortés) de la Cuenca Suribérica (NO provincia de Valencia, E España) ha revelado nuevos datos estratigráficos y sedimentológicos, que tienen implicaciones importantes sobre el marco estratigráfico, el ambiente sedimentario y la edad de estas unidades. Además, estos nuevos datos sugieren que se deberían revisar las correlaciones estratigráficas realizadas previamente entre las unidades estudiadas y aquéllas depositadas en otras áreas adya...

“…The few remaining facies correspond to the fossil or diagenetic counterparts of modern facies. Using an approach similar to that of WAGNER and van der TOGT (1973), a complete set of simple analyses (including microfacies analyses) was then run to help identifying the primary depositional macrofacies. The reconstruction of the horizontal and vertical sequence of facies enabled us to partly unravel of the last Holocene sedimentary cycle in the area studied.…”

SA complete set of analyses, including granulometry, mineral composition, clay composition, TOC, and identification of the allochems and the microfossils, was performed on this material. The facies and their genetic setting, i.e., the sequence of facies, provide a perspective on both the environmental and stratigraphical significance of their distribution, both lateral and vertical, and an example of the application of the WALTHER's law. The lower microbial mat is the mark of a transgression whereas the upper microbial mat is the mark of a forced regression. In conclusion, the sequence of facies allows identification of the last Holocene transgressive-regressive cycle that includes a forced regression, which probably dates back to 6,000 years BP.
