Album Caption: Perforated elbow, Mut well 1, Dakhla Oasis. Egypt. ca. 1964. Published in U.S. Geological Survey Water Supply Paper 1757-O, Figure 6. 1979.
Album Caption: Severely corroded bridge-slotted steel specimen from down-hole string, Mut well 2. Egypt. ca. 1964. Published in U.S. Geological Survey Water Supply Paper 1757-O, Figure 16. 1979.
Album Caption: Surface line corrosion specimens, Kharga well 1A, Kharga Oasis. Egypt. ca.1964. Published in U.S. Geological Survey Water Supply Paper 1757- O, Figure 39. 1979.
Album Caption: Key-lock joint, fiberglass well pipe. Egypt. ca. 1964. Published in U.S. Geological Survey Water Supply Paper 1757-O, Figure 33. 1979.
This data release includes 40Ar/39Ar data from the U.S. Geological Survey for samples from the Gidami gold deposit in the Eastern Desert of Egypt. Rock samples were collected by Basem Zoheir--Benha University/University of Kiel. Potassium-bearing mineral grains were separated from the bulk sample and analyzed by argon geochronology at the U.S. Geological Survey Bascom ARgon Dating (BARD) Laboratory in Reston, Virginia. The data constrain the timing of gold mineralization in the Gidami gold deposit.

Album Caption: Corroded aluminum probe, Nasser well 1. (x11) Egypt. ca. 1964. Published in U.S. Geological Survey Water Supply Paper 1757-O, Figure 26. 1979.
Album Caption: Kanat at non-flowing well, Kharga Oasis. This kanat, an ancient underground tunnel, was once used to tap a declining well below the surface and convey its water to a lower part of the oasis. Egypt. ca.1964. Published in U.S. Geological Survey Water Supply Paper 1757-O, Figure 34. 1979.

Album Caption: Corroded, aluminum specimen from down-hole string, Mut well 2. Egypt. ca. 1964. Published in U.S. Geological Survey Water Supply Paper 1757- O, Figure 17. 1979.
Cassiterite (SnO2) samples were collected from alluvial ore concentrate from the Abu Dabbab Granite in eastern Egypt. Samples (in the form of mounted loose grains) were prepared and analyzed for direct age dating on a laser ablation inductively coupled plasma mass spectrometer (LA-ICPMS) system at the U.S. Geological Survey in Denver, Colorado in February 2019. This data release accompanies the publication, 'Monazite and cassiterite U-Pb dating of the Abu Dabbab rare-metal granite, Egypt: Late Cryogenian metalliferous granite magmatism in the Arabian-Nubian Shield.' (Lehmann and others, 2020). The publication constrains the timing of the magmatic-hydrothermal processes of the Abu Dabbab Granite which represents...

Compilation of Geospatial Data (GIS) for the Mineral Industries and Related Infrastructure of Africa
This geodatabase reflects the U.S. Geological Survey’s (USGS) ongoing commitment to its mission of understanding the nature and distribution of global mineral commodity supply chains by updating and publishing the georeferenced locations of mineral commodity production and processing facilities, mineral exploration and development sites, and mineral commodity exporting ports in Africa. The geodatabase and geospatial data layers serve to create a new geographic information product in the form of a geospatial portable document format (PDF) map. The geodatabase contains data layers from USGS, foreign governmental, and open-source sources as follows: (1) mineral production and processing facilities, (2) mineral exploration...
