(Table 1) Minerals found in vesicles and fractures from DSDP Leg 54 Holes basalts@en

A variety of secondary minerals, formed in response to different oxidation and hydration states, are found in vugs and on fracture surfaces of the basalt cores from DSDP Leg 54. The minerals are smectite (blue to grey), high-magnesium calcite, manganoan calcite, aragonite, iron oxides, phillipsite, todorokite, marcasite, and hydrobiotite. The relationship of the mineral assemblages to four depositional modes of the basalts are delineated. A definite sequence and genetic link exists between mineral type and host rock which is dependent upon the origin and subsequent cooling history of the basalt.在深海钻探计划（Deep Sea Drilling Project, DSDP）第54航次所获玄武岩岩心的晶洞及破裂面中，发育有多种响应于不同氧化与水化状态形成的次生矿物。该类矿物包括蒙脱石（smectite，呈蓝至灰色）、高镁方解石、含锰方解石、文石、铁氧化物、辉沸石（phillipsite）、钡镁锰矿（todorokite）、白铁矿（marcasite）以及水黑云母（hydrobiotite）。研究厘清了该矿物组合与玄武岩四种沉积模式之间的对应关系。矿物类型与其赋存围岩之间存在明确的演化序列与成因联系，这一联系由玄武岩的成因及后续冷却历史所决定。
