中文摘要：

白音诺尔铅锌矿是我国长江以北规模最大的铅锌矿床，矿体受地层岩性、褶皱变形控制十分明显．矿区南、北矿带褶皱形态略有不同，但整体走向均为NE方向，且向SW侧伏，倾伏角约为25。左右．根据已知构造和矿化特点，用EH4连续电导率剖面成像系统对29线以南的高覆盖率地区进行了2号矿体的深部追索．结果表明，所选区域构成一个新的地球物理异常带，异常反映的深部地质体电性差异可以较好地用已知构造和矿化特点来解释，因此2号矿体在29线以南仍有延伸

英文摘要：

The Baiyinnuo＇er lead-zinc deposit is the largest lead-zinc deposit in the north part of the Changjiang river in China. Ore bodies are obviously controlled by strata lithology and fold structure deformation in this deposit. Generally, the fold axis bends down to SW direction, with an angle about 25°, and its trend is along NE direction, but the fold shape in the south ore belt is slightly different to that in the north ore belt. Based on characteristics of tectonic-controlling mineralization, the 2nd ore body＇s extend was pursued to depth situation at the high coverage fraction area in the south part of 29 line with an EH4 conductivity image system. The result shows that the studied area is a new mineralization belt. The electricity nature difference of the geologic body underground based on EH4 anomaly can be exactly explained according to the known characteristics of tectonic-controlling mineralization. Therefore, the 2nd ore body still extends to depth in the south part of 29 line.
