Abstract

Fossil worm tubes of Cretaceous age preserved in the Bayda massive sulfide deposit of the Samail ophiolite, Oman, are apparently the first documented examples of fossils embedded in massive sulfide deposits from the geologic record. The geologic setting of the Bayda deposit and the distinctive mineralogic and textural features of the fossiliferous samples suggest that the Bayda sulfide deposit and fossil fauna are remnants of a Cretaceous sea-floor hydrothermal vent similar to modern hot springs on the East Pacific Rise and the Juan de Fuca Ridge.

摘要

保存在阿曼萨迈尔蛇绿岩的拜达块状硫化物矿床中的白垩纪化石虫管，显然是地质记录中首个有文献记载的嵌入块状硫化物矿床的化石实例。拜达矿床的地质背景以及含化石样本独特的矿物学和结构特征表明，拜达硫化物矿床和化石动物群是白垩纪海底热液喷口的遗迹，类似于东太平洋海隆和胡安德富卡海岭上的现代温泉。
