| 摘 要： | 哀牢山、澜沧江、高黎贡山、念青唐古拉山等汇聚造山带变质岩中,发现一些标型或特征变质矿物间形成冠状反应边或生长环带。它们是变质过程的真实记录,反映了变形变质环境条件的不断变化,完整或直观地表现了不同地体或构造带PTt轨迹特征。可帮助恢复汇聚造山带中不同地体构造属性,为研究造山带PTtD轨迹和PTDX轨迹,提供准确资料。可从另一侧面了解汇聚造山带的演化史。 |
| 关 键 词： | 冠状反应边 生长环带 PTt、PTtD、PTDX轨迹 构造属性恢复 汇聚造山带 |

| Abstract: | In the convergent orogens of Ailaoshan,Lancangjiang,Gaologongshan and Nianqingtanggula,etc,the cap corona or growth zone is formed between some typomorphic or feature metamorphic minerals,which is the real record of metamorphic process and reflects the continuous change of metamorphic environment,shows the complete and object PTt locus characteristics of different terrain or structural zone,helpful to the recovery of structural nature of different terrain in the convergent orogen and can provide the accurate information for the study of PTtD locus and PTDX locus of orogen and the acquaintance with the evolution of convergent orogen from another side. |
| Keywords: | Cap Corona Growth Zone PTt PTtD PTDX Locus Recovery of Structural Nature Convergent Orogen |
