摘要

摘要: 白音諾爾鉛鋅礦是我國長江以北規模最大的鉛鋅礦床,礦體受地層巖性、褶皺變形控制十分明顯.礦區南、北礦帶褶皺形態略有不同,但整體走向均為NE方向,且向SW側伏,傾伏角約為25°左右.根據已知構造和礦化特點,用EH4連續電導率剖面成像系統對29線以南的高覆蓋率地區進行了2號礦體的深部追索.結果表明,所選區域構成一個新的地球物理異常帶,異常反映的深部地質體電性差異可以較好地用已知構造和礦化特點來解釋,因此2號礦體在29線以南仍有延伸.

Abstract: 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.
