摘　　要：分别建立了金矿床、铜矿床成矿预测区的划分准则和分级标准。根据成矿预测区的划分准则及分级标准,作出了播卡矿田综合信息成矿预测图,将播卡矿田划分为6个主要成矿预测区,从脆—韧性剪切断裂带深部发育特征、矿体呈尖灭再现分布规律、深部岩体发育特征、含石墨导电性剪切带、钻井原生晕深部延伸规律等5个方面重点进行了新山—马家沟金矿深部成矿预测,得出3个远景异常地段找矿前景的排序为:马家沟南部→新山西北→新山东南。The classified standards and diagnostic criteria of metallogenic prognosis areas of gold and copper deposits were set up respectively.In accordance with the standards and criteria,the authors plotted a metallogenic prognosis map of synthetic information for Boka Mine,classified Boka Mine into six main metallogenic prognosis areas,conducted a deep metallogenic prognosis for Xinshan-Majiagou gold deposit in terms of development features of brittle-ductile shear fractured belt,distribution rules of the ore bodies in pinch and reappearance way,development features of deep rock mass,graphite-bearing electricity conductivity shear belt,deep stretching rules of drilling primary halo.It was concluded that the sorting orders for the three prospect anomaly blocks were as follows：South Majiagou-Northwest Xinshan-Southeast Xinshan.
