Abstract The purpose of this study is to differentiate and characterise contouritic sands in two different locations with variable sediment compositions (siliciclastic bioclastic) based on a multiproxy approach that includes the analysis sedimentary texture, semi-quantitative geochemistry, microfacies ichnological information, as well Principal Component Analysis (PCA) applied geochemical data ...

In tropical and sub-tropical mixed siliciclastic–carbonate depositional systems, fluvial input in situ neritic carbonate interact over space time. Despite being the subject of many studies, controls on partitioning sediments remains controversial. Mixed sedimentary records, from Ashmore Trough shelf edge slopes (southern Gulf Papua), are coupled with global sea-level curves anchored to Marine I...

Well-preserved miospore assemblages are recorded from the Late Ordovician (Katian-Hirnantian), Ghelli Formation in Pelmis-gorge at the north-eastern Alborz Mountain The palynomorphs were extracted from siliciclastic deposits which are well-dated by using of marine palynomorphs (acritarchs and chitinozoans). The encountered miospore assemblages consist of 14 genera (28 species: 26 cryptospores a...

Abstract Late Cenozoic was a period of large-scale extension in the Aegean. The is mainly recorded metamorphic core complexes with little data from sedimentary sequences. exception Thrace Basin northern Aegean, which has continuous record Middle Eocene to Oligocene marine sedimentation. In Basin, Oligocene–Early Miocene characterized by north-northwest (N25°W) shortening leading termination sed...

In order to facilitate the search for new play concepts and exploration opportunities, a sequence stratigraphic synthesis of Cenomanian–Turonian interval Arabian Plate has been compiled. The is based on published datasets which have analysed within temporal framework constrained by biostratigraphy isotope stratigraphy. high resolution allows palaeogeography study area be mapped 3rd depositional...

Mixed carbonate-siliciclastic systems are complex, and their development can sometimes be difficult to understand, given the various responses each sub-environment specific forcing, such as variation in sediment supply, climatic conditions, or available accommodation. This work integrates a detailed facies, associated with depositional environment reconstruction, all of which is placed sequence...

background:   human fascioliasis is an important health problem in the province of gilan, at the caspian sea, iran. there is the overlapping of both fasciolid species, fasciola hepatica and f. gigantica . recent studies on both domestic animal and lym­naeid infection furnished evidence suggesting that f. gigantica and radix gedrosiana may be the main fasciolid and lym­naeid involved in the dise...
