Abstract

The subalpine, atmospherically fed Śnieżka peatland, located in the Polish part of the Sudetes, is one of the nominated candidates for the GSSP of the Anthropocene. Data from two profiles, Sn1 (2012) and Sn0 (2020), from this site are critical for distinguishing the proposed epoch, while an additional core Sn2 is presented to support main evidence. The Sn0 archive contains a wide array of critical markers such as plutonium (Pu), radiocarbon (F14C), fly ash particles, Hg and stable C and N isotopes which are consistent with the previously well documented 210Pb/14C dated Sn1 profile, which provides a high-resolution and comprehensive database of trace elements and rare earth elements (REE), Pb isotopes, Pu, Cs, pollen and testate amoebae. The 1952 worldwide appearance of Pu, owing to its global synchronicity and repeatability between the cores, is proposed here as a primary marker of the Anthropocene, supported by the prominent upturn of selected chemostratigraphic and biostratigraphic indicators as well as the appearance of technofossils and artificial radionuclides.

作为人类世系列候选全球边界地层类型剖面和点的希尼卡泥炭地

亚高山，大气喂养Śnieżka泥炭地，位于苏台德山脉的波兰部分，是人类世GSSP的提名候选人之一。该地点Sn1(2012)和Sn0(2020)两个剖面的数据对于区分所提出的世是至关重要的，而另一个Sn2岩芯则提供了支持主要证据。Sn0档案包含了大量的关键标记，如钚(Pu)、放射性碳(F14C)、飞灰颗粒、汞和稳定的C和N同位素，这些标记与之前记录良好的210Pb/14C年代Sn1剖面一致，为微量元素和稀土元素(REE)、Pb同位素、Pu、Cs、花粉和遗存阿米巴虫提供了高分辨率和全面的数据库。由于其全球同步性和岩心之间的可重复性，本文提出1952年在世界范围内出现的Pu作为人类世的主要标志，并提出了一些化学地层和生物地层指标的显著上升，以及技术化石和人工放射性核素的出现。
