美国有关学者认为,控制石油形成有四组因素:气候,特别是温度;营养物的供应情况;控制初期盆地形成的构造因素和控制后来石油保存的构造因素。石油地质学家和地球化学家的研究,确信石油是由生物转化而来,特別是浮游生物,因为它们的繁殖力强,能生成较多的有机质。而生物的繁殖需要温暖的气 Relevant scholars in the United States believe that there are four sets of factors controlling the formation of oil: climate, especially temperature; the supply of nutrients; the structural factors that control the formation of the early basins and the structural factors that control the subsequent preservation of petroleum. The study of petroleum geologists and geochemists is convinced that oil is derived from organisms, especially plankton, because they are highly fertile and produce more organic matter. Biological breeding requires warmth
