nebulitic structure

The dolomitized patches were produced by early diagenetic dolomitization which preferentially began within Thalassinoides burrows and spread into the surrounding lime mud.

云斑状构造是早期白云石交代作用优先沿着痕迹化石Ｔｈａｌａｓｉｎｏｉｄｅｓ潜穴进行，然后向围岩扩散而形成的。

The tremendous change that has taken place in eastern China since the Mesozoic did not result from the subduction of the Pacific plate beneath continental China but is a major geological event caused by the reworking of the lithospheric mantle by mushroom structure formed by upwelling of asthenospheric materi.

中生代以来中国东部发生的岩石圈巨变不是太平洋板块向中国大陆的俯冲所造成,而是由于软流圈物质上涌形成蘑菇云构造对岩石圈地幔的改造而引发的重大地质事件。
