为了确定热液石油形成的时间界限．我们已放得了三个不同地区样品的14C年龄，这三个地区是：加利任尼亚湾瓜伊马斯盆地．东北太平洋（埃斯卡诺巴海槽和米德尔裂谷）和东非裂谷（坦噶尼喀地堑）。这些数据确定了碳源的年龄，从而为热液石油的形成和定位提供了最大年龄。年龄最小的石油产于瓜伊马斯盆地的南海槽（3200～6600年，平均4692年）；北海村石油的年龄稍大一些（7400年）。年龄较大的石油主要产于埃斯卡诺巴海槽（17000年）和米德尔裂谷（29000年）。东非裂谷的大陆石油样品的年龄为25000年，与东北太平洋的海洋石油样品的年龄相当。这些年龄证实，热液石油的形成是一个非常迅速的过程．是在更新世晚期至现代之间的某段时间内在这些活动的热液体系中进行的。
In order to determine the time limit for the formation of hydrothermal oil. We have placed 14C ages for samples from three different regions: the Guayas Basin in the Gulf of Jayanaga. Northeast Pacific (Es Canocuba Trough and Middel Rift) and East African Rift (Tanganyika Graben). These data identify the age of the carbon source and thus provide the maximum age for hydrothermal formation and location. The youngest oil is produced in the South China Trough of the Guaymas Basin (3200-6600 years, an average of 4692 years); Beihai Village has a slightly older age (7400 years). Older oil is mainly produced in the Escañoba trough (17,000 years) and the Middel rift (29,000 years). Continental oil samples of the East African Rift have a age of 25,000 years and are comparable in age to the offshore petroleum samples from the northeastern Pacific. These ages confirm that the formation of hydrothermal oil is a very rapid process. Was carried out in these hydrothermal systems during some time between the late Pleistocene and modern times.
