即使被困在有机地质大分子(如干酪根、沥青质和固体沥青)中的碳(n-alk-1-enes)也能存活下来，因为地质大分子复杂的基质结构提供了有效的保护。这些烯烃被认为是从各种生物体中普遍存在的酯中衍生出来的。在正常成熟度增加或剧烈热事件的影响下，这些圈闭-ALK-1-烯的浓度逐渐下降，最终消失。
Even carbon numberedn-alk-1-enes, trapped inside organic geomacromolecules such as kerogen, asphaltene and solid bitumen, can survive geologic time because of the effective protection provided by the complex matrix structures of geomacromolecules. These alkenes are presumed to be derived from esters which are commonly present in various organisms. Subjected to either normal maturation increase or the impact of drastic thermal events, these trappedn-alk-1-enes gradually decrease in concentration and eventually disappear.
