Abstract We report herein for the first time, the presence and relative composition of medium volatility organic compounds in samples from a super-hot geothermal field in Mexico. We sampled ten water/vapor condensates from active exploitation wells from Los Humeros Geothermal field. We identified 48 compounds, being alkanes, aromatics and S-bearing the predominant homologues, followed by O-bearing. Evidence suggests that the origin of the hydrocarbons is mainly thermogenic derived from hydrothermal alteration of buried organic matter, supported by the presence of aromatics, S-bearing and an alkane CPI below 1. The results of this study increase the scarce knowledge of dissolved organic fraction in hydrothermal systems.

墨西哥某高温地热田凝析油中有机物的分布及来源

摘要 我们在此首次报告了墨西哥超热地热田样品中中等挥发性有机化合物的存在和相对组成。我们从 Los Humeros 地热田的活跃开采井中采集了 10 个水/蒸汽冷凝物。我们确定了 48 种化合物，包括烷烃、芳烃和含 S 的主要同系物，其次是含 O 的。有证据表明，碳氢化合物的来源主要是源自埋藏有机质的热液蚀变的热成因，并得到芳烃、含硫和烷烃 CPI 低于 1 的支持。这项研究的结果增加了对溶解有机组分的稀缺知识在热液系统中。
