| 摘 要： | 下梁子金矿床为叠加改造式层控类卡林型金矿床,集沉积地层、岩浆活动、脆韧性剪切构造活动三位一体;地层岩性含硫铁、含钙质为有利含矿岩系,为成矿准备了物质基础;岩浆作用导致围岩的夕卡岩化-角岩化,使岩石成分重组,利于成矿物质的活动;成矿以发育含矿热液的脆韧性递进剪切变形构造控制为关键,直接控制了工业矿体的分布、矿化强度与就位.研究中确定了碰撞型花岗岩与成矿的直接关系;具体划分了矿石类型,矿化期与矿化阶段,金的赋存状态等.

| Abstract: | Xialiangzi Au deposit is a stratobound Carlin-like type characterized by superimposition and rework of sedimentation, magmatism and brittle ductile shearing. The S-Fe and Ca-bearing lithologies are favorable for mineralization. Magmatism resulted in skarnization and hornfelization thus ore element remobilization. The hydrothermal fluid-bearing brittle-ductile shear zone, which is progressively deformed is the key structure to control mineralization degree and industrial ore bodies emplacement directly. Ore formation is directly related to the collisional granite thus the deposit is a rare Carlin-like deposit in Qinling area. The division of ore stages and types and Au occurrences are described. |
