环二萜类化合物已被各种研究人员在地圈（如化石树脂、煤、土壤、页岩和深海沉积物）中发现。在东北太平洋、黑海和北大西洋沉积物中发现了以脱氢松香酸为主的松香烷骨架的二萜类化合物。这些树脂衍生化合物的存在与陆源粘土成分和花粉的存在。多环二萜类化合物的存在也与其他沉积物脂质组分（如正构烷烃，正脂肪酸等）的分布模式和推断的来源相关。钾质迁移和浊流再分配是这些树脂衍生物进入深海沉积物的可能机制。这些二萜类化合物是高等植物优良的生物学标记。
Cyclic diterpenoid compounds have been found by various investigators in the geosphere (e.g. fossil resins, coals, soil, shale and deep-sea sediments). These compounds occur in significant amounts only in higher plants and are therefore potential markers of terrigenous plant lipids.Diterpenoids with the abietane skeleton (mainly dehydroabietic acid) have been identified in the lipids of sediment samples from the northeast Pacific Ocean, Black Sea and North Atlantic Ocean. The presence of these resin-derived compounds correlated with the terrigenous clay components and with the presence of pollen. The presence of polycyclic diterpenoids was also correlated with the distribution patterns and inferred sources of other sediment lipid constituents (e.g.n-alkanes,n-fatty acids, etc.).Potamic transport, followed by turbidite redistribution are the probable input mechanisms of these resin-derived compounds to the deep-sea sediments. These diterpenoids appear to be excellent biological markers of resinous higher plants.
