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.

为火星上可能存在石油类型的现象提供证据意味着为火星上过去的生命提供迹象。我们通过分析梳理（对齐）的重力撞击角来做到这一点，重力撞击角是从最近的火星引力场模型之一得出的重力（引力）方面（描述符）之一，目前具有最高的可实现精度和分辨率。在对地球和月球的特征进行密集测试后，重力方面适用于火星。我们在最大的区域中检测候选地下水/碳氢化合物/泥浆/石油含矿地点，并使用尽可能多的梳理重力走向角，均匀地排列成“板块”。它们主要但不仅仅出现在假设的火星北部古海洋（北部低地）。事实证明，梳理走向角不仅对盆地均匀有序的沉积物敏感，而且对假定的火山泥流也敏感。
