近年来,在南极地区发现了大量不同类型的陨石,这些陨石是在非常清洁的条件下保存下来的,由于低温、低湿度和缺乏工厂产生的有机酸或无机土壤酸的影响而使陨石的化学风化作用大大地减慢了,低的化学反应速率及高度清洁的南极冰高原对于保留碳 In recent years, a large number of different types of meteorites have been discovered in the Antarctic. These meteorites have been preserved under very clean conditions. The meteorite chemistry has been preserved due to the effects of low temperature, low humidity, and lack of plant-generated organic or inorganic soil acid Weathering has greatly slowed down, with low chemical reaction rates and highly clean Antarctic ice sheets that retain carbon
