菜园铅矿成矿地质条件及模式探讨

菜园铅矿属低温热液浅成矿床，矿石类型属含铅重晶石脉型，其规模、形态严格受张扭性断裂构造控制，矿源层为靠近矿脉的莱阳群地层，成矿介质来自大气降水。该文通过对其矿床地质特征、控矿因素及矿床成因的分析研究，同时通过搜集和研究区域内相类似矿床的信息资料，初步建立了其成矿模式，在分析找矿标志的基础上，提出了该区下一步的找矿方向，加大矿区外围的找矿力度，以期发现新的矿体。

Study on Metallogenic Condition and Model of Caiyuan Lead Deposit

Caiyuan lead deposit is an lowtemperature hydrothermal shallow deposit. The type of ore body is leadbearing barite vein type, and the scale and shape are strictly controlled by tensiontorsional fault structures. The source layer is Laiyang group which is close to veins, and the medium of mineralization derives from atmospheric precipitation. In this article, through analysis and study on geological characteristics, orecontrolling factors and origin of mineral deposit, by collecting and studying the information of the similar deposits in the same area, metallogenic model has been established primarily. On the basis of analyzing ore prospecting symbols, the direction for geological prospecting in this area has been put forward, and the prospecting degree of surrounding areas in this mine should be strengthened in order to discover new ore bodies.
