摘　　要：东沟钼矿床属于斑岩型钼矿床,其成矿物质来源于燕山晚期太山庙钾长花岗斑岩,成矿母岩不仅提供了矿质矿液,同时在空间位置上还控制了矿体的分布形态、产状及其规模。通过对东沟钼矿床的控矿地质条件、矿床赋存规律及区域物化遥重砂成果的整理、研究,总结出以下特点:东沟地区存在着深部可能与太山庙钾长花岗斑岩相连的隐伏岩体,由于受勘查范围的限制,矿体在东沟钼矿区外围南部未尖灭,矿体向南部有较大的延伸空间,资源潜力较大,具有较好的找矿前景。对该区南部实施勘查工作,进行东沟矿床的远景控制,将会有新的突破。Donggou molybdenum deposit belongs to porphyry molybdenum deposit,its mineralization minerals are from the late yanshanian Taishanmiao potassium feldspar granite porphyry. The mineralization mother rock not only has provided the mineralization material and the hydrothermal ore-forming solution,but also has controlled the distribution,attitude and scale of ore bodies on space position. Through sorting and researching the ore-controlling geological conditions and the deposit occurrence regularity of Donggou molybdenum deposit,the result of the geophysical and geochemical exploration,remote sensing,heavy fraction in that region,the followings are generalized,there is a concealed rock mass in Donggou region,which may be linked to Taishanmiao potassium feldspar granite porphyry. Due to the limited by the scope of exploration,ore body has not pinched out in southern area of Donggou molybdenum mine. It has a larger outspread space to the southern area. This place has a bigger resource potential and good ore prospects. To carry out the exploration work and the vision control of ore deposits in the southern area,there will be a new breakthrough.
