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

垩纪典型的“温室”气候和海洋地学界关注的焦点之。

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，研究人员已经考虑了垩纪的隔离，接着特有种在马加斯加听散布及随后从马加斯加扩散其中地区域。

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.

“盆地”构造发育模式为：从晚侏罗垩纪末期发育的山间“盆地”开始、发展早第三纪断陷湖盆的发育、再演化为晚第三纪及第四纪地陷发育阶段。
