摘要:

A technique of isotope analysis has been adopted for extremely small-size samples. Amounts of 50–100 nmol of CO2extracted from gaseous inclusions in natural quartz show δ13C values around –24‰ which indicate an organic origin of this gas, while dispersed hydrocarbons extracted from Permian sediments (mainly CH4) have δ13C below –40‰.
