| 摘 要： | 连县小带是粤北近几年发现的又一喷流沉积铅锌矿床。简要介绍其成矿环境、地质特征,讨论喷流(喷气)沉积(成矿)作用及成矿分带的主要地球化学机制,如因脉动喷流(喷气)造成盆地内地球化学性质的周期变化,引起矿石组构的周期变化等。

| Abstract: | Xiaodai lead- zinc ore deposit in Lianxian is another spout ore deposit being found in northern Guangdong. The ore forming condition and geological feature are generally introduced;and the spout (emanation) deposition (ore- forming) process and the general geochemical mechanism of ore zoning,such as pulse of spout (emanation) resulting in periodic variation of geochemical nature in the basin,and of ore fabric,etc. are discussed. |
