Abstract Peat profiles from the area of the Tunguska explosion epicentre indicate significant carbon and hydrogen isotopic effects which are clearly associated with the zone of the 1908 "catastrophe", and which cannot be attributed to any known terrestrial processes. We explain them with the presence of extraterrestrial matter similar to carbonaceous chondrites or, more probably, to cometary matter. Initial data on nitrogen content and its isotope composition are consistent with the assumption of acid rainfall following the passage and explosion of the Tunguska cosmic body, as is known to have occurred during the Cretaceous-Tertiary boundary.
摘要 通古斯卡爆炸震中区域的泥炭剖面显示出显著的碳和氢同位素效应，这些效应与1908年“灾难”区域明显相关，且不能归因于任何已知的地球过程。我们用类似于碳质球粒陨石或更可能是彗星物质的外星物质的存在来解释它们。关于氮含量及其同位素组成的初步数据与通古斯卡宇宙天体经过和爆炸后出现酸雨的假设一致，正如在白垩纪-第三纪边界所发生的那样。
