“…In contrast, the "semi-arid monsoonal" model shows a decrease in water storage in April resulting in a slight cool season bias. However, cool season biases tend to be much smaller in magnitude (less than 4 ºC) than warm season biases (as much as 24 ºC) (Kelson et al, 2020). Therefore, regardless of the interpretation of seasonal biases, our mean temperature based on clumped isotopes (14.9 ºC) suggests very cool conditions in the mid-latitude Asian continental interior during the Aptian-Albian.…”

“…The presence of vegetation (suggested by abundant root traces) may shade the soil surface from solar radiation. However, Burgener et al (2019) and Kelson et al (2020) found that this effect is rare, and samples for this study were collected from paleosol horizons deep enough (i.e., > 50 cm) to be buffered against the effects of radiative heating (i.e., Burgener et al, 2019). Seasonality of precipitation, evaporation, and evapotranspiration likely affects the degree to which a warm season temperature bias may occur.…”

“…towards lighter δ 13 C and δ O values and drier conditions favor an excursion towards heavier δ 13 C and δ 18 O values (Richoz et al, 2017). Hence, variations in chemical weathering indicators (CIA, PIA and CIW) and in the δ 13 C and δ 18 O profiles of soil carbonates across a sedimentary succession can be used to trace and assess fluctuations in the climatic conditions that prevailed in the source areas and in the sedimentary basin at the time of sediment deposition, and during pedogenesis (Nesbitt and Young, 1982;Bahlburg and Dobrzinski, 2011;Fischer-Femal and Bowen, 2020;Kelson et al, 2020;Zamanian et al, 2021). The formation of soil carbonates is a highly complex process that can complicate the interpretation of their δ 13 C and δ 18 O isotopic values (Richoz et al, 2017), as global climatic trends may be overprinted by regional factors, such as contamination with detrital carbonates, dolomitization, meteoric diagenesis, maturation or oxidation of organic matter, dis-equilibrium conditions between atmospheric (or biogenic) CO2 and soil solution, evaporation, basalt hydrothermalism, etc.…”
