Throw Light on the Heavy Economic Minerals of the Northern Part of Delta, Egypt
Keywords:Rashid and Dumyat branch, spiral bar manually, heavy economic minerals, profiles
The studied area extended from Rashid branch to the Dumyat branch, the area has a long reach to 150 km, and the area width reach to 2km. The collected samples were acquired by using spiral bar manually rotating for one meter depth. The samples were distributed along 30 profiles perpendicular to the beach, and the distance between them are about 4.5 to5 km. Each profile includes three samples representing different environments present at such profile. The distance between the samples along each profile ranging from 200 to 750 m perpendicular to the shore line. These samples analyses in the nuclear materials authority laps, and study the samples under stereo-binocular microscope. The area has average total heavy mineral (9.7%), and average of economic heavy minerals (2.8). The average percentage of Magnetite (0.58%), Ilmenite (1.4%), Garnet (0.21%), Rutile (0.05%), Leucoxene (0.15%), Zircon (0.14%), Monazite (0.005%), and Sphene (0.01%). The economic heavy minerals concentrated in the centeral part of the study area where these sediments are related to the old extinct river branches; Canopic, Sebbenytic, and Bucoloic. The area under study is very economic important.
