抚顺盆地湖泊沉积物的主量元素、总有机碳和总氮含量及碳同位素数据。

运用中国东北抚顺盆地的始新世湖泊沉积物的地球化学数据，来探索对全球气候变化的区域气候响应。化学变化指数（CIA）和斜长石蚀变指数（PIA）始终呈现逐渐的长期下降，表明抚顺盆地始新世期间从温暖湿润到相对寒冷和干旱的气候转变。这种气候趋势与全球降温和二氧化碳浓度降低大致相符，这意味着区域气候与地质时间尺度上的全球气候变化密切相关

We employed geochemical data from Eocene lacustrine sediments in the Fushun Basin, Northeast China, to investigate regional climatic responses to global climate change. The Chemical Index of Alteration (CIA) and Plagioclase Index of Alteration (PIA) consistently exhibited gradual long-term declines, indicating a climatic shift from warm and humid conditions to relatively cold and arid environments during the Eocene epoch in the Fushun Basin. This climatic trend broadly aligns with global cooling and declining atmospheric CO₂ concentrations, suggesting that regional climate is closely linked to global climate change on geological timescales.
