白垩植物

If your ground is too alkaline for individual plants they will become chloritic on chalky ground.

当然如果土质盐碱化太重，一些特定品种的植物在白垩地上会被chloritic。

All of these were composed of plants adapted to the difficult conditions due to the clayey chalk support composed by the rubble.

所有的这些树林都是由这些适应了不利立地条件的植物组成，不利的立地条件也是那些由废渣碎石产生的粘土状的白垩导致的。

The early and late Early Cretaceous palynofloras in the region have been established.

建立了研究区早白垩世早期和晚期两个孢粉植物群。

On the other hand, some deciduous gymnosperms including Ginkgoales, and the presence of growth rings in the fossil secondary wood, indicate seasonal changes.

植物组合中以丰富的热带及亚热带型植物为主要特点，未发现针叶类型的植物，说明早白垩世穆棱组沉积时，该地区的气候温暖湿润；另一方面，落叶的银杏类和松柏类，以及裸子植物木化石中具有清楚的生长轮，又说明该地区的古气候存在着季节变化。

According to the characters of the palynofloras, the Early Cretaceous palaeoecologic, palaeoclimatic, sedimentary environment as well as palaeogeographic significance have been discussed.

根据孢粉植物群的特征，探讨了该区早白垩世古生态、古气候、沉积环境及古地理意义。

Chalk or limestone soils, such as marls.

例如在白垩、或泥灰这种富含石灰石的土壤中生存的植物。

They expected to find evidence of well-known Late Cretaceous vegetation such as conifers and cycads.

他们原本期望发现晚白垩世时期著名植物如针叶树和苏铁存在的证据。

By means of the comprehensive study of the petrified wood,other plant fossils and rock groups,some principal characteristics of the ancient climate in SE China are .

根据浙江省新昌硅化木的分布与特点，应用硅化木记录的可知性和植物学的类比原理，通过该地区硅化木、其他植物化石和岩性组合等综合分析，初步探讨了早白垩世新昌盆地南洋杉型木的生态环境，以此研究该时期东南沿海地区的古气候主要特征。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
