英文摘要	新甘交界红柳河地区早二叠世玄武岩与灰岩互层,玄武岩局部发育为枕状,枕间充填灰岩。通过对剖面碳酸盐岩样品的全岩无机碳氧同位素研究发现,与玄武岩互层的层状灰岩的δ~(13)C 和δ~(18)O 平均值分别为3.2‰和-14.2‰,枕状玄武岩间的块状灰岩的δ~(13)C 和δ~(18)O 的平均值分别为-0.7‰和-18.2‰,即碳酸盐岩的碳氧同位素组成在火山快速爆发时期相对于火山活动间隙时期明显偏负。通过对层状灰岩和枕间灰岩碳氧同位素研究发现,海盆火山作用是环境变化的主要控制因素。; The early Permian basalts in Hongliuhe area on the Border between Xinjiang and Gansu Provinces are interbedded with limestone, and a small amount of limestone are filled in the triangle gap of pillow basalts. The carbon and oxygen isotopic composition of carbonates in intermittent volcanic eruption period and rapid volcanic eruption period are significantly different, respectively, delta C-13 and delta O-18 are 3.2 parts per thousand and - 14.2 parts per thousand in average in interbedded limestone which is partially positive, -0.7 parts per thousand and - 14.2 parts per thousand in average in limestone among pillow basalts which is partially negative. The research of carbon and oxygen stable isotope shows that environment variation in the marine basin is influenced greatly by volcanic eruption.; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 07; 1779-1784; 23
