Geochemical maps of Samrah and vicinity, Kingdom of Saudi Arabia
Geochemical maps of Samrah and vicinity, near Ad Dawadimi, display anomalies for the ore metals over each of the major ancient mining sites, a large contamination anomaly over the ancient ore-processing waste, and less-well defined anomalies parallel to mineralized structures. Zirconium and lanthanum display negative anomalies over altered rocks, do not display the contamination anomaly, and, for zirconium, identify the west workings at Samrah as the site of most intense alteration.
