| 摘 要： | 海底黑烟囟为当代海洋地质调查的重要发现，对于揭示地史时期块状硫化物的成矿过程中以及生命起源具有重要意义。本文初步报道在冀东中元古代块状硫化物矿床中首次发现保存完好的黑烟囟构造，它们保留了成矿流体运移的通道构造，围绕通道构造还显示良好的矿物分带现象。完全可以与现代海底黑烟囟对比，黑烟囟的发现证明了该区硫化物矿床的形成与海底喷流过程密切相关。

| Abstract: | The modern black smoker chimney and relevant sulfide at the sea floor is an important discovery of oceanic science in the last ten years. It has crucial implication for the understanding of genesis with the massive sulfide and the origin of life. Here we report the first discovery of well - preserved chimney preserved within the Mesoproterozoic sulfide deposit from Eastern Hebei. The chimney shows the mineral zonation around a tight conduit associated with fluid, which is quite similar to those formed by modern black smoker at sea floor. The identification of chimney supports the exhalation origin for the massive sulfide deposit. |
