摘　　要：Based on coinjection and/or comparison with synthesized standards, a novel C_(18-23) tricy-clic terpane series with a base peak at m/z 123 on their mass spectra have been detected andconclusively identified from the basal sandstone in the Upper Proterozoic Xiamaling For-mation, eastern Yanshan region, North China, and their molecular structure has been deter-mined as 13α(n- alkyl)- tricyclic terpanes. Dealing with the biomarker assemblage of the reser-voir bitumen, the source input of their organic material, two kinds of degradation effectsand origin of the novel tricyclic terpane series are approached herein.Based on coinjection and/or comparison with synthesized standards, a novel C_18-23 tricy-clic terpane series with a base peak at m/z 123 on their mass spectra have been detected andconclusively identified from the basal sandstone in the Upper Proterozoic Xiamaling For-mation, eastern Yanshan region, North China, and their molecular structure has been deter-mined as 13α（n- alkyl）- tricyclic terpanes.
