dyke swarms emplacement constitutes one of the conspicuous features of the neoproterozoic arabian-nubian shield (ans) (~950-540ma). based on field investigations, petrographic and geochemical characteristics the dyke swarms in nw sinai (egypt) comprise of mafic (dolerite-trachy-basalt-basalt), intermediate (basaltic-andesite trachy-andesite) and felsic (rhyodacite-rhyolite) varieties. geochemic...

In this paper, a recommender system based on rough mereology was presented for predicting best cultivation dates for wheat in Egyptian Sinai Peninsula according to the required mean temperature for germination stage during October to December. The weather data was hourly collected from El-Arish weather station in north Sinai government from 1985 to 2013. As far as we know, this was the rst stud...

Based on field studies, museums collections and literature sources, the current knowledge of the tiger beetle fauna of Israel and adjacent lands is presented. In Israel eight species occur, one of them with two subspecies, while in the Sinai Peninsula nine species of tiger beetles are now known. In the combined regions seven genera from two tribes were found. The Rift Valley with six cicindelid...

A long-term taxonomic and faunistic survey of the family Nabidae from Israel and the Sinai (Egypt) was conducted based primarily on material housed in the National Collection of Insects at Tel Aviv University, Israel (TAUI). A key is provided to all species and information is given for each, species including its distribution, previous records from the study area and life history details if ava...

a r t i c l e i n f o 14 C adjusted model age Paleowesterlies Paleomonsoon Sixteen groundwater samples collected from production wells tapping Lower Cretaceous Nubian Sandstone and fractured basement aquifers in Sinai were analyzed for their stable isotopic compositions, dissolved noble gas concentrations (recharge temperatures), tritium activities, and 14 C abundances. Results define two group...

Large albitite bodies associated with explosive brecciation, fenite aureoles, intrusive carbonate rocks, olivine dolerites, and copper mineralization are described from the Dead Sea rift region in the south-eastern Sinai Peninsula. The main carbonate phases comprise breunnerite and dolomite with actinolite the main phase in the fenites. Field and isotopic evidence indicates that the intrusive c...
