Barlangi jégképződmények korának és fejlődésének vizsgálata izotópos elemzések alapján | Age and evolution of cave ice based on isotope analyses

The thousand years old cave ice records information about the Late Holocene environmental changes. Isotope studies are proxies to reveal frozen information. Using 3H-3He and radiocarbon methods few individual ice layers were dated. Furthermore, short term (2.7 cm/yr) and long-term (0.79-0.9 cm/yr) g...

Description
Summary:The thousand years old cave ice records information about the Late Holocene environmental changes. Isotope studies are proxies to reveal frozen information. Using 3H-3He and radiocarbon methods few individual ice layers were dated. Furthermore, short term (2.7 cm/yr) and long-term (0.79-0.9 cm/yr) growth rates were calculated. The two growth rates show a ratio of ca. 3 : 1. Identifying the strata of impurities the different ice producing periods are separated. So the delta-18O curve of the ice core, which can represent maximum 850+/-50 years long duration, is divided into intervals according to freezing age.
