Studies in the center and margin of the Medee Basin, a Mediterranean deep-sea hypersaline anoxic basin, and at a reference site during Penelope cruise (2007), revealed the existence of a 7 m-thick halocline, with high salinity (328 psu), and high sedimentary organic carbon and biopolymer concentrations. The 194 16S rRNA sequences retrieved were grouped into 118 unique phylotypes. Pseudomonas ge...

Abstract The Central Graben is a Mesozoic sedimentary basin that significantly influenced by rift and salt tectonics. Its southern part located in the German Dutch sectors of North Sea. Even though studies exist on tectonic stratigraphic development Danish Graben, as an important link less investigated. We aim to fill this gap investigate from Latest Triassic Early Cretaceous, relative influenc...

The Neoproterozoic Era is of widespread geobiological interest because it marks the critical transition from a world of microbes to one where animals become an established feature of the landscape. Much research into this time period has focused on the ventilation of the oceans, as this is widely considered a primary factor driving the diversification of complex, multicellular life. In this stu...

This study aims to identify favorable oil–gas reservoir facies in the Chishan group of the Wubao fault zone (Gaoyou sag, Subei basin, China) using the methods of outcrops and cores observation, granularity analysis, scanning electron microscope, log data, etc. The results suggest that the Chishan group in the studied area mainly develops desert sedimentary system, and contains five kinds of fac...

gomish-tappeh zn-pb-cu (ag) deposit is located 90 km southwest of zanjan, in northwestern part of urumieh-dokhtar volcano-plutonic zone. exposed rocks at the area include oligo-miocene volcano-sedimentary and sedimentary sequences as well as pliocene volcano-plutonic sequence (andesite porphyry dykes, dacitic subvolcanic dome and rhyodacitic volcanics). alteration in the deposit developed as si...

Voluntary iodization of table salt prior to 1995 had a beneficial effect on the prevalence of goitre in some areas in South Africa. However, it was, due to limited availability and unequal access, unsuccessful in eradicating iodine deficiency and endemic goitre. Against this background the international focus on the eradication of IDD stimulated the introduction of mandatory iodization of table...

The Karoo basin of South Africa exposes a succession of Upper Permian to Lower Triassic terrestrial strata containing abundant terrestrial vertebrate fossils. Paleomagnetic/magnetostratigraphic and carbon-isotope data allow sections to be correlated across the basin. With this stratigraphy, the vertebrate fossil data show a gradual extinction in the Upper Permian punctuated by an enhanced extin...

Salinity is rising in many southern African and Australian rivers with unknown effects on aquatic organisms. The extent of spatial variation, at any scale, in salt tolerances is unknown and therefore whether data from one location should be used elsewhere. The acute tolerances (72-hour LC50) to sea salt of 49 macroinvertebrate taxa from the south-east of the Eastern Cape (SEEC), South Africa we...

OBJECTIVE Lactating women and their infants are susceptible to iodine deficiency and iodine excess. In South Africa, no data exist on the iodine status and thyroid function of these vulnerable groups. METHODS In a cross-sectional study, urinary iodine concentrations (UIC), thyroid function, and breast-milk iodine concentrations (BMIC) were assessed in 100 lactating women from a South African ...

The Southern Rhodope Core Complex is a wide metamorphic dome exhumed in the northern Aegean as a result of large-scale extension from mid-Eocene to mid-Miocene times. Its roughly triangular shape is bordered on the SW by the Jurassic and Cretaceous metamorphic units of the Serbo-Macedonian in the Chalkidiki peninsula and on the N by the eclogite bearing gneisses of the Sideroneron massif. The m...
