In this study, the concentration and sources of aliphatic and petroleum markers were investigated in 105 samples of Anzali, Rezvanshahr and Astara cores from the southwest of Caspian Sea. Petroleum importation was diagnosed as a main source in most depths of cores by the results of unresolved complex mixture, carbon preference index and hopanes and steranes. From the chemical diagnostic parameters, petroleum inputs in sediment of cores were determined to be different during years and the sources of hydrocarbons in some sections differed than Anzali and Turkmenistan and Azerbaijan oils. Diagenic ratios in most sediments of upper and middle sections in Astara core were determined to be highly similar to those of Azerbaijan oil, while the presence of Turkmenistan and Anzali oils were detected in a few sections of Anzali and Rezvanshahr cores and only five layers of downer section in Anzali core, respectively.
在这项研究中，对来自里海西南部的安扎利、雷扎凡沙赫尔和阿斯塔拉岩芯的 105 个样本中的脂肪族和石油标志物的浓度和来源进行了调查。未解析复杂混合物、碳偏好指数和藿烷和甾烷的结果表明，石油进口是大多数岩芯深度的主要来源。从化学诊断参数来看，确定了核心沉积物中石油输入在不同年份的差异，并且一些部分的碳氢化合物来源与安扎利和土库曼斯坦和阿塞拜疆石油不同。阿斯塔拉岩芯中上部和中部的大多数沉积物中的成岩比值与阿塞拜疆石油非常相似，而在安扎利和雷扎凡沙赫尔岩芯的一些部分以及安扎利岩芯的下倾部分的仅 5 个层中检测到了土库曼斯坦和安扎利石油的存在。
