Calculated the lower limit of abnormal after the plane through the delineation of the contour map of the occurrence and analysis of abnormal findings were as follows: work area on the lithology in terms of more or less divided into two parts, East and West, the western area for the low-resistivity, lithology is metamorphic carbonaceous sandstone or slate, for the emperor in eastern areas, lithology for granite and granite porphyry, quartz vein occurrence in eastern and more, these quartz veins is into the eastern part of the resistivity of the form of alternating high and low.

计算了异常下限值后，通过圈定了平面等值线图上的矿点异常和其它分析得到结论如下：工区就岩性而言大致划分为东西两部分，西部为低阻区，岩性为变质砂岩或炭质板岩，东部为高祖区，岩性为花岗岩及花岗斑岩，东部多赋存石英脉，这些石英脉是的东部电阻率成高低交替的形式。
