| 英文摘要 | Five series of benzohopanes were identified in a set of immature to early-oil-window early Cretaceous sediments from the ZK1006 well, Chaoyang Basin, NE China. Series a (C31 31-C35), 35 ), b (C33 33-C35), 35 ), and c (C31 31-C35) 35 ) benzohopanes form by different pathways, while the newly-found series d (C31 31-C34, 34 , maybe to C35?) 35 ?) and e (C31 31-C32, 32 , maybe to C35?) 35 ?) benzohopanes have similar formation mechanisms. Series a is usually the predominant benzohopane series, but occasionally samples are dominated by series c benzohopanes. Series b benzohopanes may be associated with terrigenous organic matter. Series a and b benzohopanes are possibly influenced by redox properties, while paleosalinity more likely controls the formation and enrichment of series c benzohopanes. Two novel parameters (a benzohopane index, and the C 35 /C 34 benzohopane ratio) are proposed to be useful paleoenvironmental proxies in the study area. A high benzohopane index and C 35 /C 34 benzohopane ratio may indicate an anoxic environment. |
