《"Palaeoenvironmental setting of lacustrine stromatolites in the Miocene Wudaoliang Group, northern Tibetan Plateau"》
Wudaoliang stromatolites showδ13C values ranging from2.43‰to 4.12‰,about 1.20‰higher than skeletal limestones(Yi et al.2008)and marlstones(Wu et al.2009)of the same formation.Highδ13C values might point to a significant photosynthetic effect in the water body.In photosynthetic process12C is preferentially assimilated by primary producers,resulting13CDICenrichment in lake water and highδ13C in the carbonates(Kerby and Raven1985;Hollander and Mc Kenzie 1991;Gu et al.1996).Therefore,despite high salinity,a significant primary carbon production is evident for this depositional period of the lake in the Hoh Xil Basin.
