大问题。没有足够的数据分辨率目前,无论是空间还是暂时。有地质时期认为经历了更高的侵蚀率的基础上丰富的沉积相,如在三叠纪。也有许多沉积盆地沉积演化的利率是众所周知的。但这很大程度上取决于当地的地理/构造条件,如提供的住宿空间构造沉降,所以它没有提供信息在全球范围内发生了什么。使它更加困难,有充分的迹象表明我们偏见的方式测量(侵蚀)[1]和[2](沉降),夸大最近运输率相对于长期。有你想要的全球视角,作者需要一个连贯的,全球范围内,具有统计代表性的过去的侵蚀或沉降的措施,这对于每一个地质时期。但侵蚀和沉积需要数年时间来确定一个特定的盆地和造山带设置为一个特定的时期;差距是巨大的。唯一的大致量化在全球范围内是Miocene-Pliocene-Quaternary时期。 And even there the discussion is very open. The following studies suggest that **global erosion/sedimentation rates have increased during the last 4-6 million years**. The first is based on a compilation of delta sedimentation rates: > Zhang, P., Molnar, P.& Downs, W. R. Increased sedimentation rates and > grain sizes 2–4 Myr ago due to the influence of climate change on > erosion rates. Nature 410, 891–897 (2001). The second uses thermochronology, mostly Apatite Fission Track analyses: > Herman F, Seward D, Valla PG, Carter A, Kohn B,Willett SD, Ehlers TA. > 2014. Worldwide acceleration of mountain erosion under a cooling climate. Nature 504: 423–426. DOI: 10.1038/nature12877 Both interpret the acceleration of erosion as a result of the changes in Earth's climate during that period: initiation of the glacial interglacial cycle in the northern hemisphere. Due to the gaps in the geological outcrop record, and to our limited capacity of dating sediments, my bet is that it will take decades at least to have a reliable graph like the one you aim at. Hope this helps. [1]: http://www.nature.com/nature/journal/v505/n7483/full/505294a.html [2]: http://clasticdetritus.com/2010/06/28/using-sedimentation-rates-to-infer-long-term-global-climate-change/
