Based on the published data of pillow lava-hosted mineralized veins, this study compares post-magmatic fracturing, fluid flow, and secondary mineralization processes in the Troodos and Izu–Bonin supra-subduction zone (SSZ) and discusses the crucial factors for the development of distinct vein types. Thin section and cathodoluminescence petrography, Raman spectroscopy, fluid inclusion microthermometry, and trace element and isotope (⁸⁷Sr/⁸⁶Sr, δ¹⁸O, δ¹³C, Δ₄₇) geochemistry indicate that most veins consist of calcite that precipitated from pristine to slightly modified seawater at temperatures < 50 °C. In response to the mode of fracturing, fluid supply, and mineral growth dynamics, calcites developed distinct blocky (precipitation into fluid-filled fractures), syntaxial (crack and sealing), and antitaxial (diffusion-fed displacive growth) vein microtextures with vein type-specific geochemical signatures. Blocky veins predominate in all study areas, whereas syntaxial veins represent subordinate structures. Antitaxial veins occur in all study areas but are particularly abundant in the Izu–Bonin rear arc where the local geological setting was conducive of antitaxial veining. The temporal framework of major calcite veining coincides with the onset of extensional faulting in the respective areas and points to a tectonic control on veining. Thus, major calcite veining in the Troodos SSZ began contemporaneously with volcanic activity and extensional faulting and completed within ~ 10–20 Myr. This enabled deep seawater downflow and hydrothermal fluid upflow. In the Izu–Bonin forearc, reliable ages of vein calcites point to vein formation > 15 Myr after subduction initiation. Therefore, high-T mineralization (calcite, quartz, analcime) up to 230 °C is restricted to the Troodos SSZ.

根据已公布的枕形熔岩宿主矿化静脉的数据，本研究比较了Tr​​oodos和伊豆–布宁超俯冲带（SSZ）的岩浆后压裂，流体流动和次生矿化过程，并讨论了发育的关键因素。不同的静脉类型。薄截面和阴极发光岩石学，拉曼光谱，流体夹杂物测温，和痕量元素和同位素（⁸⁷ SR / ⁸⁶的Sr，δ ¹⁸ O，δ ¹³ C，Δ ₄₇）地球化学表明，大多数脉脉由方解石组成，方解石是在温度<50°C时从原始沉淀到略微改性的海水中沉淀的。响应于压裂，流体供应和矿物生长动力学的模式，方解石形成了明显的块状（沉淀成流体填充的裂缝），语法上的（裂缝和封闭）和反轴（扩散填充的位移生长）静脉微纹理特定的地球化学特征。在所有研究领域中，块状静脉占主导地位，而语法上的静脉代表从属结构。在所有研究区域中都存在反轴静脉，但在伊祖-波宁后弧地区尤为丰富，那里的局部地质环境有利于反轴静脉的形成。大方解石脉的时间框架与各个区域伸展断裂的发生相吻合，并指出了对脉的构造控制。因此，Troodos SSZ的主要方解石脉开始同时发生，并伴有火山活动和伸展断层，并在约10-20 Myr内完成。这使得深层海水下降和热液上升。在伊豆–波宁前臂，可靠的静脉方解石年龄表明俯冲开始后> 15 Myr的静脉形成。因此，Troodos SSZ只能承受高达230°C的高T矿化作用（方解石，石英，碱金属）。这使得深层海水下降和热液上升。在伊豆–波宁前臂，可靠的静脉方解石年龄表明俯冲开始后> 15 Myr的静脉形成。因此，Troodos SSZ只能承受高达230°C的高T矿化作用（方解石，石英，碱金属）。这使得深层海水下降和热液上升。在伊豆–波宁前臂，可靠的静脉方解石年龄表明俯冲开始后> 15 Myr的静脉形成。因此，Troodos SSZ只能承受高达230°C的高T矿化作用（方解石，石英，碱金属）。
