陆核

分别代表了太古宙的陆核发展及地块形成和早元古宙的裂谷构造等大地构造环境。

They indicate that the Archeozoic tectonic environment is continental nucleus development and crustal block formation , and the Early Proterozoic tectonic environment is represented as rift .

结果表明：古老的陆核、原地台、地台和地块等稳定地区内部的密度值横向变化小，年轻的褶皱带等活动地区内部的密度值横向变化大。

The conclusion show that : the density horizontal change small inside the stable region of the old continental nucleus , original platform , platform , and massif but the density horizontal change big inside the movable region of young fold band .
