Abstract A relatively complete conodont record from Famennian to the Mississippian/Pennsylvanian boundary was investigated in Anarak section, Central Iran. The studied interval belongs Bahram, Shishtu, Ghaleh and Absheni formations. part of section (Bahram Formation) ranges Palmatolepis triangularis Zone into Bispathodus ultimus Zone. Not all zones could be defined due lack indicative species. ...

Arranged from oldest to youngest, the main granitic rock units exposed in Khour Abalea are metagabbros, cataclastic rocks, ophiolitic melange, pegmatite and lamprophyre dykes. The presence of radioactivity associated with heavy bearing minerals construction materials—like granite—increased interest extraction process. As it turns out, rocks play an important economic part examination area’s sur...

Acartiella faoensis, previously known as Acartia (Acartiella) is a calanoid copepod which was observed during biodiversity survey, July-August of 2018, on the lower-middle stretch Hooghly River (upper reaches estuary). The species reported for first time from aforementioned locality well anywhere eastern India and perhaps entire country. Individuals belonging to both sexes have been collected s...

Some 43 samples collected from surficial sediments of Semnan Province (Alborz zone) and NE Isfahan Province (Central Iran zone) were analyzed, for constrains on provenance. Sand fraction were analyzed by XRF analyzer Philips Model PW 2450 in the laboratory of the Geology Survey Iran (GSI). Precision was 0.01%. Furthermore, 8 selected sediment samples and 8 samples from rock units from surroundi...

Abstract A new formula for determining the suspended sediment load in Khour Al-Zubair port has been proposed using dimensional analysis. Six cross-sections have identified at Basrah province, South of Iraq purpose conducting field measurements during two tidal periods (Neap and Spring). The study involved taking hydraulic fluid properties, sampling by section every 2 h to get effective paramete...

Pampus argenteus (Euphrasen, 1788) is one of the most commercially important fish in North Gulf region, Iraq particular. It's stocks were critically endangered. The study showed semi-artificial spawning. mature brooders collected from region corresponding to Khor Al-Zubair. semiartificial spawning was done by mixing sperm and ova live fish.
