陕西东塘子背斜北翼存在含矿的隐伏背斜

Ore-bearing Concealed Anticline in North Wing of Shanxi Dongtangzi Anticline

东塘子背斜北翼存在含矿隐伏背斜，背斜（矿体）在铅硐山铅锌矿与东塘子铅锌矿采矿范围的边界线附近，长度80—100m，厚度2—5m，铅＋锌品位在10％左右，矿体向南倾，向西侧伏，侧伏向290°左右，侧伏角35°-40°，目前该矿控制的高度在200m以上，最低标高在1350m。该矿为手搬崖铅锌矿在采、探矿过程中新发现的一个盲矿体。该矿的发现提醒我们勘查不能留死角，为以后的找矿、资料开发又多了一条思路。

Ore-bearing concealed anticline exists in the north wing of theDongtangzi anticline. The anticline orebody is loca- ted around the mining boundary of the Qiandongshan lead-zinc deposit and the Dongtangzi lead-zinc deposit, with 80-100 meters in length, 2-5 meters in thickness, and around 10% in lead ＋ zinc grade. The orebody dip to the south and pitch to the west with pitch trending of around 290° and pitch angle of 35 ° to 40° .Currently the controlled deposit height is 200 meters above, with minimum elevation in 1350 meters. The deposit was newly discovered in the process of mining and exploration in the Shoubanyan lead-zinc mine. Its discovery reminds us that no corner be left in the survey, and provides a new thought in the prospecting and development.
