To reveal the impact of biomass input (marine algae, terrestrial plants and lacustrine Botryococcus braunii) on the composition of high molecular weight organooxygen and organonitrogen compounds (O_x, N_y and N_yO_x), solvent extracts of immature–early mature rock and coal samples were systematically characterized by Fourier transform ion cyclotron resonance mass spectrometry using different ionization modes. In total, 16 samples from the marine Schöneck, Dynow and Posidonia formations, the lacustrine Wealden Formation and the terrestrial New Zealand coals were investigated.

Coals as the in-situ deposits of terrestrial plants consist to a great degree of aromatic polyoxygenated O_x and N₁O_x compounds, representing the degradation products of lignin like phenolic ketones and carboxylic acids as well as their condensation products with the degradation intermediates of labile organonitrogen compounds. Aliphatic O_x moieties derived from plant protective constituents principally waxes and cutan show a pronounced even or odd carbon number predominance of the C₂₃–C₃₃ species with C₂₆, ₂₈, ₃₀ or C₂₇, ₂₉, ₃₁ as the major homologs. In contrast, marine and lacustrine microbial communities contribute plentiful middle-chain C₂₂, C₂₄ or C₂₃, C₂₅ O_x compounds. Marine rock extracts are characterized by abundant organonitrogen compounds, especially N₂ and N₂O_x classes, interpreted as signatures of protein-rich marine algae that were successfully preserved via a degradation-recondensation pathway, whereas the low protein content of lacustrine Botryococcus braunii is reflected by a low amount of N₁O_x and N₁ classes. Highly aliphatic algaenan of Botryococcus braunii sterically protected its oxygen-bearing groups from degradation, leading to a great abundance of O_x compounds, furthermore, it characterizes the Botryococcus braunii source by substantial heteroatomic species containing more than 40 carbon atoms.

为了揭示生物质输入（海藻、陆生植物和湖相布氏葡萄球菌）对高分子量有机氧和有机氮化合物（O _x、N _y和 N _y O _x）组成的影响，未成熟-早熟岩石的溶剂提取物采用不同电离模式的傅里叶变换离子回旋共振质谱系统对煤样进行了系统表征。总共研究了来自海洋 Schöneck、Dynow 和 Posidonia 地层、湖泊 Wealden 地层和新西兰陆地煤炭的 16 个样本。

煤作为陆生植物的原位沉积物，在很大程度上由芳香族多氧化的 O _x和 N ₁ O _x化合物组成，代表了木质素的降解产物，如酚酮和羧酸，以及它们与降解中间体的缩合产物。不稳定的有机氮化合物。源自植物保护成分（主要是蜡和表皮）的脂肪族 O _{x部分在具有 C 26}、₂₈、₃₀或 C ₂₇、_{29的 C 23} -C ₃₃物种中表现出明显的偶数或奇数碳数优势，₃₁为主要同源物。相比之下，海洋和湖泊微生物群落贡献了丰富的中链 C ₂₂、C ₂₄或 C ₂₃、C ₂₅ O _x化合物。海洋岩石提取物的特点是富含有机氮化合物，尤其是 N ₂和 N ₂ O _x类，这被解释为通过降解-再冷凝途径成功保存的富含蛋白质的海藻的特征，而湖相Botryococcus braunii的低蛋白质含量是由少量的 N ₁ O _x和 N _1反映类。Botryococcus braunii的高度脂肪族藻聚糖在空间上保护其含氧基团免于降解，从而产生大量的 O _x化合物，此外，它通过含有超过 40 个碳原子的大量杂原子物种来表征Botryococcus braunii来源。
