Subfossil azoxanthellate deep-sea coral mounds occur at 355–410 m on the continental slope of the NE Tyrrhenian Sea between Gorgona and Capraia islands, Tuscan Archipelago. These low-relief patch reefs are at present buried by a thin muddy drape. Their age is latest Pleistocene. The colonial scleractinian Madrepora oculata is the major frame builder, in association with the solitary coral Desmophyllum dianthus...
The knowledge of Pleistocene reef facies of Belize, Central America, is largely limited to outcrops in the northernmost part of the country. Otherwise, Pleistocene limestone, which forms the basement of the modern barrier and atoll reefs, occurs in the subsurface and is to a major extent unstudied. Based on the study of 40 m of core from 25 rotary core holes collected on central and southern Belize...
Carbonate eolian dunes can form huge sand bodies along the coasts but are seldom described in the pre-Quaternary record. The study of more than 600 thin-sections collected in present-day, Holocene and Pleistocene dunes from Sardinia, Crete, Cyprus, Tunisia, Morocco, Australia and Baja California confirms that these deposits can be easily misinterpreted as shallow marine at core or thin-section scale...
Coastal sedimentary deposits including beach and dunes within the south-central region of the Gulf of California show a high percentage of biogenic components, up to 84%, derived from the fragmentation of organisms that, among other oceanographic factors, reflect wave energy and effect of seasonal winds. Our report shows that due to high-energy waves, coastal deposits on points or islands with a northern...
Although eolian deposits are known to record the dominant winds, secondary conditions such as wind reversals during wintertime can also be observed in the petrographic composition and facies succession. Thus, eolian deposits are used here as a local paleoclimatic proxy. The spatial distribution of the depositional facies, early diagenetic imprints, and early fracture network of a coastal Pleistocene...
The depositional conditions that characterized the sedimentary filling in the southern sector of the Guadalquivir Basin during the late post-orogenic Neogene have been established through the sedimentological study of the Plio-Pleistocene outcrops along the Cadiz coast (SW Spain). The study has contributed to a better interpretation of the regional stratigraphy and helped to establish both depositional...
A mid-latitude coralgal bioconstruction (Tyrrhenian coast of Calabria, southern Italy) and associated sedimentary facies record climate and sea-level changes of this coastal area during the Pleistocene. The coralgal bioconstruction, characterized by Cladocora caespitosa bafflestone and red algae bindstone, associated with Spondylusgaederopus sp.-rich boundstone, formed as a result of submergence...
