世界上许多低温到中温热液和斑岩型Ａｕ±Ｃｕ产出与钾质火成岩和橄榄粗玄岩相关或产于其中。容矿岩体多以高卤族元素如Ｃｌ和Ｆ、大离子亲石元素和贫高场强元素为特征。与钾质火成岩套有关的成矿作用往往限于三类构造环境：晚期大洋岛弧、大陆弧和后碰撞弧。晚期大洋岛弧的实例有巴布亚新几内亚Ｌｉｌｉｒ岛中更新世的Ｌａｄｏｌａｍ金矿床，斐济ＶｉｔｉＬｅｖｕ上新世的Ｅｍｐｅｒｏｒ金矿和澳大利亚新南威尔士奥陶纪Ｇｏｏｎｕｍｂｌａ斑岩铜金矿床。大陆弧的实例包括中生代一新生代智利安第斯山脉的许多低温金和斑岩型Ｃｕ－Ａｕ矿床。后碰撞弧的一个实例是中新世巴布亚新几内亚的Ｐｏｒｇｅｒａ金矿床。对于这些晚期大洋岛弧、大陆弧和后碰撞弧中与金一铜矿床有关的钾质火成岩，其云母斑晶中ＣＬ的含量与同构造环境非高钾岩石相比特别高。大洋岛弧中矿化钾质火成岩的云母斑晶中似乎以十分高的ＣＬ和Ｆ为特征。
Many of the world’s low-temperature to medium-temperature hydrothermal and porphyry-type Au ± Cu production is associated with or produced in potassic igneous and olivic rocks. The ore-bearing rock mass is characterized by high halogen elements such as Cl and F, large ion lithophile elements and poor field strength elements. The mineralization associated with potassic igneous rocks is often limited to three tectonic settings: the late oceanic island arc, the continental arc and the post-collision arc. Examples of late-stage oceanic arcs include the Pleistocene Ladolam gold deposit on Lilir Island, Papua New Guinea, the Emperor Gold mine in the Viti Levu Pliocene, Fiji, and the Ordovician Goonumbla porphyry copper-gold deposit in New South Wales, Australia. Examples of continental arcs include many low-temperature gold and porphyry Cu-Au deposits of the Mesozoic-Cenozoic Chilean Andes. An example of a post-collision arc is the Porgera gold deposit of the Miocene Papua New Guinea. For these late-stage oceanic arcs, continental arcs and post-impact kalium-related igneous deposits associated with the gold-copper deposits, the content of CL in the mica phenocrysts is particularly high compared with non-kalinite rocks in the same tectonic setting. The mineralized porphyry mica phenocrysts in the Oceanic arc appear to be characterized by very high CL and F.
