Researches on geophysical anomalies over stratabound copper deposits in the copper belt province of Zambia

Stratabound copper deposits constitute the main kind of copper deposits in the copper belt province of Zambia. Copper depos?its occur within sediments of Lower Roan Formation, Katanga Supergroup. Based on geological features of stratabound copper deposits, the authors studied geophysical anomalies of known orebodies in three stratabound copper deposits by using IP intermediate gradient and EH-4 electromagnetic sounding. On such a basis, the authors summarized the regularity of electrical anomaly from ore-bearing rocks and main wall rocks, and established geophysical electrical signal model for main wall rocks and ores, which can guide the prospecting for the same kind of copper deposits in the copper belt province of Zambia.
