从Ｄｅｌａｍｅｒｉａｎ造山带的碎锆年代看冈瓦纳早古生代太平洋边缘的发育Ｔ．Ｒ．Ｉｒｅｌａｎｄ等大陆边缘板块的重组通常伴随着强烈侵蚀，继而发生源区不明的单一碎屑物的巨量沉积。然而，沉积物源区地壳要素的重要信息通常记载在碎锆石的年代谱上。这些年代谱对于了...
Development of the Early Paleozoic Pacific margin of the Gondwana from the zircon dating of the Delamerian orogenic belt. R. The reorganization of continental margins such as Ireland is often accompanied by intense erosion followed by the massive deposition of single clastic matter of unknown source. However, important information on crustal elements in the sedimentary source zone is often recorded on the chronological spectrum of zircon. These chronological spectrum for the ...
