黄海南部海底风成砾石的发现

中国科学院海洋研究所青岛 266071

摘要:

于1992年5—6月在南黄海海底打捞到大量海底砾石。通过对这些砾石的形态和表面特征的研究,结合其它证据,发现其形成原因可能与冰期低海面时期陆架上的风力作用有关,因此将这些砾石命名为“风成砾石”。

Abstract:

Careful study of many stones collected by bottorntrawl in June, 1992 by the “RV Scinece I” of the Institute of Oceanology, Academia Sinica, during investigations in the (southern) Yellow Sea continental shelf showed they were composed of sandstone (sandy gravel) and probably resulted from eolion erosion in the glacial period. These stones were mostly longish and in cylindrical form, and showed many signs of abrasion by wind, for which reason they are called “ventifacts”.

Key words: Ventifact, Eolion erosion, Glacial period
