赞比亚铜带省的主要铜矿床为层控型，铜矿体赋存于加丹加（ Katanga）超群下罗恩亚群岩层中。在了解层控型铜矿床地质特征的基础上，在该地区3个已知典型层控型铜矿床上进行了激电中梯和EH?4高频大地电磁系统的试验，通过已知矿体和物探异常的对比研究，总结了该区域含矿岩石和主要围岩的电性异常规律，并建立了主要围岩和矿体的地球物理电性示意模型，为寻找同类型的矿床提供依据和指导。
讚比亞銅帶省的主要銅礦床為層控型，銅礦體賦存于加丹加（ Katanga）超群下囉恩亞群巖層中。在瞭解層控型銅礦床地質特徵的基礎上，在該地區3箇已知典型層控型銅礦床上進行瞭激電中梯和EH?4高頻大地電磁繫統的試驗，通過已知礦體和物探異常的對比研究，總結瞭該區域含礦巖石和主要圍巖的電性異常規律，併建立瞭主要圍巖和礦體的地毬物理電性示意模型，為尋找同類型的礦床提供依據和指導。

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.
