近边缘的

The source rocks of the former are mainly the well-developed, huge thickness of Neogene marine depression sedimentary rocks and Miocene marine sedimentary rocks; those of the latter are significantly the rift sediments of Paleogene continental facies, and large-scale source rocks of medium-deep lacustrine facies and inshore paludal facies with coal measure strata well-developed.

根据南海北部边缘新生代沉积盆地结构、构造特征可将其划分为走滑伸展型和断陷裂谷两大类型，前者以新近系巨厚海相坳陷沉积及海相中新统烃源岩发育为突出特点，后者则以古近系陆相断陷裂谷沉积和大规模中深湖相烃源岩、近海沼泽相煤系烃源岩发育为主要特征，这些烃源岩的发育展布规律、有机质丰度和生烃母质类型、成熟演化特点以及生烃潜力等均差异较大。
