| 中文摘要:<正> 一、地体概念形成的历史回顾 德人Gerth五十年代在南美洲南端首先发现(竹蜓)科化石。Ross,Douglass,Danner等人六十年代又先后在北美西部发现特提斯型(竹蜓)科生物群,并进行了古生物地理的研究工作,为后来出现的地体概念准备了生物地层学材料。七十年代初期Monger和Ross研究了加拿大科迪勒拉地区(竹蜓)科化石的分布,发现特提斯型与非特提斯型(竹蜓)科化石群空间上紧邻并列。1972年Irwin研究北加利福尼亚克拉马茨山的古生代和三叠纪地层,提出了地体概念。 |

| ON TERRANE--A LATEST CONCERN IN THE STUDY OF PLATE TECTONICS |
|
|
| Abstract:Terrane, a new term in plate tectonics, has been accepted by more and more geologists. It was first used by Irwin in 1972 when he was investigating the Paleozoic and Triassic strata in the Klamath Mountains in California. In 1977, Jones, Silberling and Hillhouse described a typical terrane--the Wrangellia terrane, and studied it on the part of paleontology, structure and paleomagnetism, which is a standard example for terrane study. It was at the 1983 Circum-Pacific Terrane Conference in Stamford University that Howell and Jones gave it a somewhat complete definition.This paper introduces the study of terrane in combination with some examples in China. It also deals with their classification, activity, origin and the subsequent effect of terrane accretion. |
