云南东川地区播卡矿田金铜等多金属矿综合信息成矿预测

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,从脆一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、含石墨导电件剪切带、钻井原生晕深部延伸规律等5个方面重点进行了新山一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.

Metallogenic prognosis on Boka Au Cu Mine Field of Dongchuan region in Yunnan

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.
