A-俯冲带术语,在中国大地构造学中广为应用,若考虑其沿革、应用状况较为岐乱。作者从各家厘定A-俯冲带涵意进行评述,并提出C-俯冲(中国型俯冲)的8点特征与A-俯冲对比和区别。本文最后建议B、A、C俯冲用在造山带形成的不同阶段来解决这一矛盾。

The terminology of A-subduction is rather confusion in the geotectonics of Chinathough it is popularly used by Chinese geologists for a long period.After making reviewson the various definitions and expressions of this teetonic term,the author of this paperput forward the conception of C-subduction(Chinese-type subduction)with eight geological characters which have been compared with those of A-subduction. Consequently,it issuggested that three B,A,and C subductions should be expressed different orogenic stagesof plate subduction, continental collision and intracontinental sequence, respectively.
