摘要

为火星上可能存在的油类生物提供证据，意味着为火星上曾经存在生命提供了线索。我们通过对精梳(对齐)重力走向角的分析来做到这一点，这是来自火星最近的引力场模型之一的重力(引力)方面(描述符)之一，目前具有最高的可获得精度和分辨率。在对地球和月球的特征进行密集测试后，将重力方面应用于火星。我们用尽可能多的重力走向角，均匀排列成“板块”，在最大的区域探测地下水/碳氢化合物/泥浆/含石油的候选地点。它们主要出现在假想的火星北部古海洋(北部低地)中，但不仅如此。结果表明，梳状走向角不仅对均匀有序的盆地沉积物敏感，而且对假定的火山泥流也敏感。

Hydrocarbons on Mars

Abstract Providing evidence for possible oil-type occurrences on Mars means providing an indication for the past life on Mars. We do this via analysis of the combed (aligned) gravity strike angles, one of the gravity (gravitational) aspects (descriptors) derived from one of the recent gravitational field models of Mars, currently having the highest accessible precision and resolution. After intensive testing for features on the Earth and the Moon, the gravity aspects are applied for Mars. We detect candidates for the groundwater/hydrocarbon/mud/petroleum-bearing sites in the largest areas with as many as possible combed gravity strike angles, uniformly ordered into ‘plates’. They appear mainly but not only in the hypothetical northern Martian palaeo-ocean (the northern lowlands). It turns out that the combed strike angles are sensitive not only to uniformly ordered sediments of the basins, but also to supposed lahars.

期刊介绍： International Journal of Astrobiology is the peer-reviewed forum for practitioners in this exciting interdisciplinary field. Coverage includes cosmic prebiotic chemistry, planetary evolution, the search for planetary systems and habitable zones, extremophile biology and experimental simulation of extraterrestrial environments, Mars as an abode of life, life detection in our solar system and beyond, the search for extraterrestrial intelligence, the history of the science of astrobiology, as well as societal and educational aspects of astrobiology. Occasionally an issue of the journal is devoted to the keynote plenary research papers from an international meeting. A notable feature of the journal is the global distribution of its authors.
