Central和North Deborah金矿床位于澳大利亚维多利亚中部浊积岩地体中的一个世界级金矿省.是本迪哥金矿田15个采矿中心中的一个。金矿化主要产在多次变形的下奥陶统变浊积岩中的穹隆和逆断层系统中,变形作用和逆冲活动发生在450～420Ma,与沸石～绿片岩相的区域变质作用同期。Central和North Deborah矿床有6个阶段的含矿石英脉,每一阶段具有依次发育的各自的几何形态和矿物共生组合等特征,其中,第1、2和4阶段含金,而3、5、6阶段不含金。
The Central and North Deborah gold deposits are a world-class gold province in the turbidite body of central Victoria, Australia, one of 15 mining centers in the Bendigo goldfield. The main mineralization of gold mineralization in the deformation of the Lower Ordovician turbidite in the dome and reverse fault system, the deformation and thrusting occurred in 450 ~ 420Ma, and zeolite ~ greenschist facies metamorphism over the same period . The Central and North Deborah deposits have six stages of ore-bearing quartz veins, each of which has its own geometric morphology and symbiosis of mineral assemblages, with stages 1, 2 and 4 containing gold and 3, 5, 6 stages without gold.
