在实验室中生长的一硫化铁球和管具有与在爱尔兰石炭纪银矿喷流沉积矿体中发现的化石黄铁矿葡萄状体和烟囱相似的形态。我们设想，在最早的海洋中，在温泉（100-200摄氏度）中生长的类似的精细结构为生命提供了培养室和流动反应器，通过磷酸化和硫化铁表面上有机分子的生长来起源。这种在实验室中生长的硫化物结构可用于生命起源实验。
Iron monosulphide globules and tubes grown in the laboratory have similar morphologies to the fossil pyrite botryoids and chimneys found in the Silvermines exhalative sedimentary ore-body of Carboniferous age in Ireland. We envisage analogous fine structures growing at hot springs (100-200 degrees C) in the earliest oceans as having provided the culture chambers and flow reactors for life to originate by phosphorylation and growth of organic molecules on the iron sulphide surfaces. Such sulphide structures grown in the laboratory could be used in origin-of-life experiments.
