与基莫洛斯(Kimolos)岛南部上新世一更新世酸一中性火山岩有关的原生高岭土中含有高岭石和石英±方英石.蒙脱石很少出现,而明矾石却很常见,且比重晶石或石膏更普遍。高岭石显示出无序结构(Hinckiey指数变化于0.6和1.1之间),且沿c轴存在着层错。元素Nb,Th,Ce和Sr,La,V构成两组,它们之间具有明显的互为相关关系,高岭土比母岩富集这些元素。K,Rb,Y和Ba同长石含量正相关,但随着高岭土化作用的增强而减少.矿物组合显示出由不同热液蚀变类型所造成的带状分布的模式.根据基莫洛斯的明矾石一钾长石-钾云母-石英共生矿物的三相点所做的研究,提出了一条假定的轨迹来表示各种矿物组合形成时所需K_2SO_4和H_2SO_4浓度的大致范围。
Primary kaolinite, associated with the Pliocene-Pleistocene-neutral-volcanic rocks in southern Kimolos Island, contains kaolinite and quartz ± cristobalite, while montmorillonite is rare, whereas alunite is common and specific gravimetric Stone or plaster is more common. Kaolinite shows disordered structure (Hinckiey index varies between 0.6 and 1.1) and there is a fault along the c axis. The elements Nb, Th, Ce and Sr, La and V constitute two groups with obvious correlations with each other. Kaolinite enriches these elements more than the parent rock. K, Rb, Y and Ba are positively correlated with feldspar content but decrease with increasing kaolinization.The mineral assemblage shows a banded distribution pattern caused by different hydrothermal alteration types.According to Kimolos’ Alunite-K-feldspar-kiemite-quartz symbiotic minerals, a hypothetical trajectory was proposed to show the approximate ranges of K 2 SO 4 and H 2 SO 4 concentrations required for the formation of various mineral assemblages.
