| 中文摘要:采用Sm-Nd同位素定年方法，测得江苏北部新沂地区踢球山榴辉岩岩体时代为221.6±8.4 Ma,Sm-Nd年龄被看作为踢球山超高压变质之后板块折返过程中的高压榴辉岩相重结晶阶段年龄。中朝板块与扬子板块碰撞时代主要发生在晚三叠世。 |

| Abstract:Sm-Nd isotope age of 221.6±8.4 Ma has been obtained for three eclogite bodies in Tiqiushan area，northern Jiangsu Province. Evidence shows that the Su-Lu belt can be regarded as a part of the Qinling-Dabie folded zone. Collision between Sino-Ko-rean and Yangtze plates might have occurred around Late Triassic. |
