白垩纪的

Cretaceous granites form a northerly trending belt.

白垩纪花岗岩的分布呈带状向北延伸。

Abstract :The Cretaceous greenhouse climate and paleoceanography is one of hot topics in the Earth sciences during the past twenty years.

白垩纪典型的“温室”气候和海洋一直是学界关注的焦点之一。

In both cases, the researchers have evoked scenarios of Cretaceous vicariance, followed by endemic species radiation within Madagascar and subsequent dispersal from Madagascar to other areas.

这些情形，研已经考虑了白垩纪的隔离，接着特有种在马加斯加听散布及随后从马加斯加扩散到区域。

The basin tectonic model: it is intermont basin during late Jurassic to early Cretaceous, developed into faulted-lacustrine basin in Eogene, and evolved into depression in Neogene and Quaternary.

“盆”构造发育模式为：从晚侏罗世到白垩纪末期发育的山间“盆”开始、发展到早第三纪断陷湖盆的发育、再演化为晚第三纪及第四纪陷发育阶段。
