The thermal and pH stability of selected flavonoids has been determined under simulated geologic conditions. Thermolytic rates and products for various regimes, as determined by gas chromatography-mass spectroscopy, indicate the potential usefulness of flavonoids as thermometric indicators in sediments. The parametric factors affecting flavonoid stability are used to geochemically characterize angiosperm "green leaves" (36 to 25 x 10(6) years old) from Succor Creek and indicate that these sediments have not experienced temperatures higher than 80 degrees C or extreme pH shifts (beyond the range 6.3 to 7.2) during postdepositional maturation.
已在模拟地质条件下测定了选定类黄酮的热稳定性和 pH 值稳定性。通过气相色谱-质谱法测定的不同条件下的热解速度和产物表明，类黄酮作为沉积物中的测温指标具有潜在的用处。影响类黄酮稳定性的参数因素被用来地球化学特征化 succor creek 的被子植物“绿叶”（36 到 25 x 10(6)年），并表明在沉积后成熟过程中，这些沉积物的温度没有超过 80 摄氏度，也没有经历过极端的 pH 值变化（超出 6.3 到 7.2 的范围）。
