论文摘要
我们提出了一种非生物地质机制，该机制说明了Greaves等人，2020年检测到的丰度。我们假设我们假设在地幔中形成的痕量磷化物将通过火山主义将其表面浮出水面，然后通过随后弹出大气层，在那里可以与水或硫酸反应形成磷酸。为了研究该假设的合理性，我们进行了数量级的计算顺序。我们认为，当今的活跃火山症可以产生与产生磷酸磷化物源所需的速率。我们的假设要求维纳斯目前经历高玄武岩火山的速度，这与航天器观测和实验室实验一致。
We propose an abiotic geological mechanism that accounts for the abundance of phosphine detected by Greaves et al., 2020. We hypothesize that trace amounts of phosphides formed in the mantle would be brought to the surface by volcanism, and then subsequently ejected into the atmosphere, where they could react with water or sulfuric acid to form phosphine. To investigate the plausibility of this hypothesis, we carry out an order of magnitude calculation. We suggest that active volcanism today could produce a rate comparable to that required to produce the phosphide-source of the phosphine. Our hypothesis requires that Venus be currently experiencing a high rate of basaltic volcanism, one that is consistent with spacecraft observations and laboratory experiments.
