摘要
本文通过研究区域地质背景及该区成矿地质特征,系统总结了该区控矿因素,认为该区矿化受地层、构造及隐伏岩体控制明显。作者根据该区特有的成矿地质条件,结合区域成矿规律,探讨建立了坳下地区成矿模式,认为该区坳下-北山尖一带应主要寻找(层控)热液充填交代型萤石矿,而北山尖-北山坑一带应主找隐伏(层控)矽卡岩型锌铜多金属矿,同时兼顾斑岩型多金属矿床。
According to the regional geological background and the geological features of the area, this paper systematically summarizes the ore controlling factors, and thinks that the mineralization is controlled by strata, structure and concealed granitic rock bodies. According to the special geological conditions of the area, combined with regional metallogenic regularity, this paper proposes a metallogenic model and a prediction model for the studied area. In the Aoxia-Beishanjian area, the main prospecting direction should be focused on the(stratabound) hydrothermal filling type and replacement type fluorite deposits, whereas in the Beishanjian-Beishankeng area, the focus should be in the concealed deposits of skarn type Cu-Zn deposits, and taking into account the porphyry type polymetallic deposit.
