The present study focused on investigating the impact of geological setting on the groundwater occurrences of the Lower Cretaceous sandstone aquifer (Malha). The Lower Cretaceous sandstone aquifer is subdivided into 3 units according to their lithological characters for the first time in this present work. The study area is dissected by normal faults with their downthrown sides due north ...
· Statement by the Ministry of Environment on the emergence of a shark in southern Sinai The Ministry of Environment has received a report that three people have been attacked by a shark in the Ras Mohammed area of south Sinai, which has resulted in some injuries, and this has required them to be taken to hospital for necessary aid and appropriate measures.
and to compare species composition and number of occurrence in these substrates. Materials Methods Study area The Saint Katherine area is situated in the southern part of Sinai between 33°57' to 34°00' South, 28° 33' North and 28°26' to 28°34' East (Danin, 1983). Generally, the area is composed of igneous and metamorphic rocks; chiefly granites are intensely dissected and rugged (Said ...
the South Sinai population are characterized by a lack of vital resources and health care, poor nutrition, an archaic, tribal social structure, and centuries of living in an unchangeable, severe arid mountainous semidesert environment. In this paper we will review the data collected by Tel Aviv University during the course of expedition to South Sinai in 1979–1982 to try to bring clar ...
Baryte occurs in a wide range of colors, including colorless, yellow, blue, and white. However, its softness, brittleness, perfect cleavage, and high density make it of little use as a gemstone. Crystals vary a great deal and may be transparent or opaque, with a variety of habits from tabular to massive. A baryte .
The study of mineral occurrence in the Saint Catherine area, southern central Sinai, Egypt (Figure 1a 1b) was undertaken to evaluate the potentiality for base and precious metal deposits in the area. Research and fieldwork took place during early April and early July, 2000. Three prospects were visited for evaluation and samples were collected and prepared for petrographic analysis. Regional ...
yellow and white silica sand from south and north sinai. our production is about 200000 ton per year of yellow silica sand for construction purposes. and about 500000 ton per year of white silica sand which is ideal for glass manufacturing industry. natural gravel from wadi elnatron city. about 1000 ton per month with diffenet sizes which is ideal for industrial floors and paints industry Road ...
Barite occurrence has been studied in twenty two localities and the host rocks include sandstones, shales, dolerites, granite and gneiss. Shales and sandstones have the greatest occurrence of barite. The mineral occurs as veins trending NESW, NS and NWSE. They occur in a fracture system crosscutting the lower Benue Trough axis suggesting a possible genetic relationship with the Azara ...
Marine cyanobacterial mats were cultured on coastal sediments (Nivå Bay, Øresund, Denmark) for over three years in a closed system. Carbonate particles formed in two different modes in the mat: (i) through precipitation of submicrometersized grains of Mg calcite within the mucilage near the base of living cyanobacterial layers, and (ii) through precipitation of a variety of mixed Mg calcite ...
Barite Mining Process,Technology, Appliions, Patent. Baryte is used in the manufacture of paints and paper. Baryte that is used as an aggregate in a "heavy" cement is crushed and screened to a uniform size. Barite (BaSO4) is a nonmetallic mineral used primarily as a weighting agent in drilling muds in the oil and gas industry.
18/08/2017 · Two modes of occurrence are characteristic, one in cavities in galena, the other in concentric layers around a nucleus of galena. In the former case fine crystals are developed, in the latter the mineral is in masses. The crystals look like those of barite, but are soluble in nitric acid while the barite is insoluble.
is loed in south Sinai which includes the highest mountainous peaks in Sinai (2641 m at Gabal Catherine; ). Saint Catherine area is characterized by an arid climate with a mean annual rainfall of about 60 mm, though the high peaks receive orographic precipitation, some in the form of snow, which may reach up to 300 mm annually. Occasional precipitation over the Saint Catharine ...
E. Kotzé, C. Gauert PGE distribution in the chromitite layers at Eastern Chrome Mine, Eastern Bushveld Complex, South Africa: A descriptive study with comparison of EPMA and LAICPMS methods for detection of trace PGE in base metal sulphides, South African .
The sulfur and oxygen isotope composition of the sulfate was analyzed at the University of Cambridge. Sulfate was precipitated as barite and pyrolyzed at 1450 °C in a temperature conversion element analyzer (TC/EA), and the resulting carbon monoxide (CO) was measured by continuous‐flow GS‐IRMS (Delta V Plus) for its δ 18 O SO4.
