| Fig. 2. Distribution of 25-norhopanes (m/z 177) in typical crude oil samples from the Tazhong uplift (C29H-C35H refer to hopanes; C29Ts refers to C29 18α(H)-norneohopane; TsN, TmN C28NH-C32NH refer to 25-norhopanes). (a) TZ11, S, 4301.00- 4307.00 m; (b) TZ113, S, 4525.35-4671.42 m; (c) TZ 74, O, 4683.40-4699.05 m; (d) TZ 122, O, 4631.88-4733.92 m. |
