Web1 jul. 2024 · We present the first stable isotope (δ 13 C and δ 18 O) speleothem record from continental Croatia retrieved from two coeval stalagmites from Nova Grgosova Cave. U-Th dates constrain the stalagmite growth history from 10 ka to the present, revealing coeval growth between 7.8 and 5.6 ka. http://skleg.gyig.cas.cn/cy/yjy/200910/t20091021_2905081.html

WebHendy (1971) proposed a test for isotopic equilibrium conditions in speleothems in which the δ18O and δ13C should be measured along the length of individual growth bands. If the samples had been significantly affected by kinetic fractionation due to rapid CO 2 degassing and/or evaporation, significant variability in Web16 jan. 2024 · Studied Speleothems and Methodology Anoop Kumar Singh2 Chapter First Online: 16 January 2024 227 Accesses Part of the Springer Thesesbook series (Springer Theses) Abstract Considering the vast expansion of limestone host rock throughout the Himalaya, we studied six caves in the different sectors (Fig. 3.1) under varying … ruth lathrope anaconda mt https://womanandwolfpre-loved.com
