摘要

南极洲利文斯顿岛Sally Rocks的石英多金属矿脉产于Miers Bluff组，特别是Sally Rock段的沉积序列，由泥岩和砂岩的薄层交替组成。矿脉由黄铜矿、闪锌矿、方铅矿、黄铁矿和毒砂组成。黄铜矿和闪锌矿为主，方铅矿次之，黄铁矿和毒砂次之。根据地质环境、质地和矿物组合，Sally Rocks的成矿作用可确定为热液成矿，这与赫德半岛其他矿点的成因相对应。

Mineral composition of quartz-polymetallic veins in Sally Rocks, Livingston Island, Antarctica

The quartz-polymetallic veins from Sally Rocks, Livingston Island, Antarctica are hosted in the Miers Bluff Formation, particularly in the sedimentary sequences of the Sally Rocks member, consisting of thin bedded alternation of mudstone and sandstone. The veins consist of chalcopyrite, sphalerite, galena, pyrite, and arsenopyrite. Chalcopyrite and sphalerite predominate, galena is second in distribution, and pyrite and arsenopyrite are in a subordinate amount. According to the geological setting, textures, and mineral assemblages, the ore mineralization in Sally Rocks can be determined as hydrothermal which corresponds to the genesis of the other ore occurrences in the Hurd Peninsula.
