Abstract A possibly prominent role for Green Rust minerals in life's emergence is inferred from a comparison of their structural, mechano-dynamic and electrochemical properties and of the layout of bioenergetic, i.e. free energy converting processes in extant organisms. From fundamental thermodynamic considerations, the conversion of environmental free energy into the decrease of entropy that defines life is an indispensable ingredient for life to emerge. A specific scenario for life's emergence mediated by Green Rust minerals in the framework of the alkaline hydrothermal vent hypothesis is proposed.

关于粘土矿物在生命出现中的重要性的原因和方式

摘要 通过比较它们的结构、机械动力学和电化学特性以及现有生物中生物能(即自由能转换过程)的布局,可以推断出绿锈矿物在生命出现中可能扮演的重要角色。从基本的热力学考虑,将环境自由能转化为定义生命的熵减是生命出现不可或缺的组成部分。提出了在碱性热液喷口假说框架内由绿锈矿物介导的生命出现的特定情景。
