论全球性中-新生代陆内造山作用与造山带

ON GLOBAL MESO CENOZOIC INTRACONTINENTAL OROGENESIS AND OROGENIC BELTS

对不同类型造山作用与造山带的深入剖析，在现代地学研究中占有重要的位置。迄今对造山带类型划分以及陆内（ 板内） 造山带是否存在及其形成机制问题，尚有不同认识。文章在阐明造山带分类准则的基础上，将全球性中－ 新生代造山带划分为陆缘型、陆间型与陆内型三大类。对陆内造山带则划分出发育在前寒武纪古克拉通基础上、发育在前中生代陆缘、陆间造山带基础上两种类型。文内还对全球性中－ 新生代陆内造山作用与造山带的展布特点。

The profound study of different types of orogenesis and orogenic belts occupies an important position in modern geosciences. Until recently among the geoscientists there are still different views on the classification of orogenic belts, the existence of intracontinental or intraplate orogenic belts and their formation mechanism. Three aspects are dealt with in this paper: (1) On the basis of description of the classification criteria of orogenic belts, the global Meso Cenozoic orogenic belts may be subdivided into three major types-the continental margin, intercontinental and intracontinental types. (2) The intracontinental orogenic belts can be considered as indication of two main types developed on the Premambrian cratonic basement and on the Pre Mesozoic continental margin or intercontinental orogenic belts. (3) The distribution characteristics and formation mechanism of the global Meso Cenozoic orogenesis and orogenic belts, as well as the significance of continental dynamics are also discussed.
