近年来,在我国前寒武纪不同时代的地层中发现了大量的痕迹化石,其中前寒武纪冰期前的痕迹化石主要分布于我国北方的长城纪和青白口纪地层中。这些痕迹化石产出时代古老,表明在我国北方14~17亿年前的海水中就可能生活有古老的后生动物,这些痕迹化石的发现对于探索后生动物的起源及演化具有重要意义。前寒武纪冰期后所发现的痕迹化石主要分布于我国西南地区震旦纪晚期的地层中,这些痕迹化石在震旦纪地层中的广泛分布,对震旦系及震旦系与寒武系界线的划分对比将提供重要依据。 相似文献

袁复礼教授字希渊,他曾是我的学术导师。1939年,我随他在西康省(今四川省西部)做地质工作半年有余。我们曾在会理县通安测绘金矿和铜矿地质图件,在会理县北发现猫猫沟的碱性岩体等。我们是比较早的到西康做工作的地质学者。那里的高山深谷给我们很深的印象,在那里我们遇到过土司和彝族头人,增长了许多见识。 相似文献
