Geochemistry Of Iron Ore Aswan

Mineralogy, geochemistry and the origin of high

2017-1-1 · The marine origin of the oolitic iron ores from Aswan assumes that the iron from these ores was derived from the seawater (hydrogenous) and therefore, reflects the geochemistry of the salt water. This trend is observed for the major oxides and trace elements of the studied ores.

Mineralogy, geochemistry and the origin of high

The Coniacian-Santonian high-phosphorus oolitic iron ore at Aswan area is one of the major iron ore deposits in Egypt. However, there are no reports on its geochemistry, which includes trace and rare earth elements evaluation.
