Dated from Proterozoic to Mesozoic, they have poly-circle characteristics, found from one tectonic circle to another, which is very rare in the worldwide orogens. This reveals that the orogen and stable area of the world, the mantle and crust states of the Proterozoic and Phanerozoic are different in tectonic evolvement and dynamic process and that the rapakivi granite of the Qinling-Kunlun is a kind of orogenic granite different from the stable area of the Proterozoic.

它们出现在每一个大的造山旋回晚期，即向另一个构造旋回的转折期，这在世界造山带中是十分罕见的，反映出世界上造山带与稳定区元古宙和显生宙的地慢与地壳状态是不一样的，有着不同的构造演化历史和动力学过程，表明秦岭－昆仑地区的环斑花岗岩是一种有别于元古宙稳定区的造山型环斑花岗岩。

The author expounds the concept of Ecozoic Era and of Community, the origins of Ecozoic Era thoughts, the relations between Ecozoic Era and religions and other cultural factors, forgiveness and Grace, and probes into the foundations of future Ecozoic Era and social communities, which reveal the essence of Ecozoic Era stressing a mutually favourable balance that should be established between ecological nature and the future forms of social communitie...

作者论述了生态时代和共同体观念、生态时代观念的思想来源、生态时代与宗教等文化因素的关系、宽恕和恩惠，探讨了未来生态时代和社会共同体的基础。其主要的思想内容是强调未来的社会共同体形式应该与生态自然之间建立起相互有益的平衡，改造我们的文化以使生态时代的生活成为现实。

Features and innovations in this study:(1) Longest successive time scale of Precambrian samples is studied;(2) The environmental and biological significances of the difference between . the carbon isotopic compositions of kerogen and coexisted carbonate were discoved;(3) The difference of biogeochemical processes between Proterozoic closed and open sea system was considered in the disccussion;(5) It is first time to carry out the chemolysis and thermolysis of kerogen in Precambrian organic matter research.(6) It is first time to apply molecular organic geochemical data to the reconstruction of Proterozoic Rodinia Supercontinent.

此项研究具有以下特色和创新之处：(1)研究对象连续时间跨度最长；(2)研究内容涉及面较全面；(3)较早详细探讨了前寒武纪沉积有机质的分子特征与古环境和生物群落的演化关系；(4)独立推导和论证了δ〓C〓和δ〓C〓的差值的生物和环境的重要意义；(5)在前寒武纪有机质研究中区分了局部封闭环境下的生物地球化学循环过程与广域海环境下的生物地球化学过程的差异；(6)开展了前寒武纪干酪根化学和热降解研究；(7)开创性地将分子有机地球化学的数据应用于元古宙Rodinia超大陆的重建中。
