中文摘要:
      浙江治岭头金银矿床产于中下元古界陈蔡群变质岩内.断裂控矿.成矿物质来源于特定岩性段,经地下热水循环富集,沿断裂充填沉淀,于燕山中晚期形成工业矿床.本矿床是一个地下热水成矿的典型,成因归属笔者厘定的热水型层控矿床.
英文摘要:
      This ore deposit and ore bodies occur as veins in a fractured zone (trending roughly E-W) developed in the metamorphosed rock of Chencai Group.The ore veins are arranged as en echelon.Ore-forming elements are dominated by gold and silver.There are two main mineralization i.e.sulfide-poor-gold (silver)-quartz veins and Au (Ag)-multi-metal quartz veins.Wall rock alterations of silicification sericitzation and Pyritization are symmetricaly developed.Zhi Lingtou area is located in a low grade metamorphism belt with well development of fractures and high Au-abundance.And here is the geothermal anomly area during Late Jurassic and Early Cretaceous.All this is the special condition favourably to form this deposit.The deposit were formed during Late Yanshan Movement as a super-hydrothermal Au-deposit whose ore-forming materials were derived from Cheneai Group.Ore fluid is the descending meteoric water-formed hot brine which were driven by structure and heat source to circulate and leach out Au,Ag and other ore-forming material from Chencai Group and emplaced in the ore-locating structural space through F1 fracture and the like.
