The Life Explosion at Cambrian Period brings forth a question and challenge to Darwin s theory of gradual and continuous evolution.
寒武纪生命大爆发 ,对达尔文渐进连续的进化论发出了诘难和挑战 ,本文根据 2 0世纪末现代分子生物学研究的最新成果 ,试探性地解释了寒武纪生命大爆发的成因和机
The relationship between the proterozoic Era and explosive evolution of the life on the Cambrian period was preliminary explored by an Ecological and Evolutionary approach in this paper.

The authors discuss some major geological issues in Pre-Cambrian and Mesozoic ear in the South -East China in the light of recent geological mapping and re-expound the geological texture of Mesozoic ear in the South-East China.
作者根据近期一系列地质编图所取得的认识,就中国东南部前寒武纪和中生代地质的一些主要问题进行了讨论。
Therefore,the Re-Os age of molybdenite in the Lüliang period not only provides evidence for existence of the Pre-Cambrian metallogenic period,but also shows the prospecting direction to find molybdenum deposits and the metamorphic porphyry-type copper-molybdenum ore in this area.
因此,吕梁期辉钼矿Re-Os年龄的获得,一方面证实了前寒武纪成矿期的存在,另一方面也为该地区寻找钼矿及变斑岩型铜钼矿指出了找矿方向。
The regional ore-forming process was closely related to the Pre-Cambrian crystalline basement.
笔者认为,区域内铅锌(银)成矿与前寒武纪基底变质岩关系密切,矿体产于特定的地层层位和岩性建造(大理岩、含碳碎屑岩)内,并受一定构造部位的控制,华力西期岩浆活动对成矿具有改造变富作用,矿床成因类型属沉积变质-热液改造型层控矿床。
