      大洋板块地层(OPS)简介及评述

      Introduction and commentary on ocean plate stratigrapgy

      摘要:
      大洋板块地层(Ocean Plate Stratigraphy)是由日本地质学家Isozaki在1990年首先提出来的,基本含义是大洋板块在从洋中脊到海沟俯冲带的运动过程中形成的一套构造-沉积地层.近年来,关于大洋板块地层的研究取得了长足的进展,丰富了大洋板块地层的内涵.本文着重介绍大洋板块地层的基本概念、物质组成、形成环境及构造特征.在此基础上,对大洋板块地层在区域地质矿产调查中的作用进行了讨论,建议在造山带地质研究中采用"俯冲增生杂岩"取代"大洋板块地层".因为在成因上,地层并不等同于杂岩.
      Abstract:
      The concept of ocean plate stratigraphy was proposed by Japanese geologist Isozaki Y and some other experts in 1990.OPS is a tectonic-sedimentary sequence,which is set up by ocean plate movement from oceanic ridge to sea trench.Research on OPS has gained remarkably progress,which has enriched the meaning of OPS.This paper introduces basic concept,components,formation en-vironment,and structural features of OPS.On such a basis,this paper discusses the role of OPS in regional geological and resources sur-vey.It is preliminarily suggested that subduction accretional complex(SAC)should be used in place of'ocean plate stratigraphy'in the study of orogenic belt.As'stratigraphy'is not genetically equivalent to 'complex',the SAC is better than the OPS in usage.
