引言近年来,北美克迪勒拉是通过分离的构造地层地体增生而形成的这一认识已经得到可资利用的新的地质、地球物理和古生物资料的支持(Jones等,1981;Jonts等,1983;Coney等,1980;Davis等,1978;Balke等,1983)。同样的增生过程似乎也影响了环太平洋边缘的大部分地区。为了探讨这一假说,我们已经编制了初步的环太平洋地体图。本文的目的是回顾Coney等(1980)和Jones等(1983)所提出的地体分析 INTRODUCTION In recent years, the recognition that North American Cordillera was formed by separate tectonic stratigraphic accretions has been supported by the availability of new geophysical and geophysical and paleontological data (Jones et al., 1981; Jonts et al. 1983; Coney et al., 1980; Davis et al., 1978; Balke et al., 1983). The same proliferation seems to have affected most parts of the Pacific Rim. To explore this hypothesis, we have prepared a preliminary map of the Pacific Rim. The purpose of this paper is to review the terranean analysis proposed by Coney et al. (1980) and Jones et al. (1983)
