《"Palaeoenvironmental setting of lacustrine stromatolites in the Miocene Wudaoliang Group, northern Tibetan Plateau"》
Furthermore,we compared the oxygen isotope of Wudaoliang stromatolites with the Holocene travertines in the Qiangtang Basin(Niu et al.2013).The source water of the hot spring travertines is of meteoric origin(Tian et al.2001;Zhang et al.2002).A significantly elevatedδ13C(up to 11.7‰)is found in these travertines,possibly related to a deep source of CO2(Tian et al.2001;Zhang et al.2002).Similarδ18O values of stromatolites to those of the Holocene travertines thus may also indicate a mixed origin of hydrothermal fluids with the Miocene period local rainfall,presuming the monsoon precipitation was similar to present conditions.However,uncertainty remains with this hypothesis,since the monsoon precipitation on northern Tibetan Plateau could have had different isotopic composition during the Miocene(see Polissar et al.2009).Further studies are required to address this problem.
