摘要
云南马关县李子坪林场锡多金属矿处于都龙老君山复式花岗岩基西侧,该矿区有两种类型的锡矿,一是受断层构造控制的中-高温热液型矿床,二是受地形地貌控制,面状分布的残坡积矿床。断裂构造及硅化、黄铁矿化等围岩蚀变是重要的找矿标志。
Liziping forest farm Sn multimetallic deposit of Maguan,Yunnan is in the W side of Dulong Laojunshan composite granite batholith.There are 2 types of Sn deposit in the orefield,ore is the middle-high T hydrothermal deposit controlled by fault and the other is the eluvium-slope wash areal distribution Sn deposit controlled by landform.The fault,silisification,pyritization,etc wall rock alteration are the important prospecting criteria.
