6 The 3rd-order sequence have been identified in early Cretaceous, the position of sequence is erected on 2 sets andesite.

3将下白垩统划分为6个三级层序，指出本区两层安山岩的层序位置。

The andesite lava (114Ma) and quartz porphyry (94Ma) are of Early Cretaceous age.

安山岩（114Ma）和石英斑岩（94Ma）则是早白垩世火山活动的结果。

The Late Jurassic-Early Cretaceous activity produced basaltic and basaltic andesitic lavas(146Ma,137Ma), followed by gabbro intrusion(135Ma) and aplite dyke (129Ma).

侏罗纪末～早白垩世初的火山活动除有熔岩（146Ma，137Ma）喷出外，还发育有辉长岩侵入体（135Ma）和辉绿岩岩墙（129Ma）等次火山岩。

Old English cealc, related to Dutch kalk and German Kalk, from Latin calx see calx

"麦斯"、和"粉笔"。氢氯甲基安非他命是无色透明的块状晶体，。。。2。白垩，粉笔

Except for Aodiju deposit, the other deposits are located in the malmstone stratum of liuju area of the Cetaceous Maton hill group.

除凹地苴矿床外，其余矿床均赋存于上白垩统马头山组六苴段的砂岩地层中。

It was sealed by a wall and contained chalky soil to the depth of one metre.

它被一堵墙密封著，仿如白垩时期的泥土深达一公尺。

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。

This conclusion is supported by:(1) typical red color, whatever it is shale, marlstone, chert, and or limestone, with their matrix rich in patches of Fe oxide.

通过沉积学、古生物学、沉积地球化学等研究表明，藏南上白垩统海相红层床得组为底层水高度氧化的沉积环境。

The passive continental marginal basins of South America formed in Late Jurassic-Early Cretaceous as Gondwana land splitting, underwent pre-rift stage, synrift stage, transitional period and drift episode, formed sets of generating rock and reservoir-cover rock compages.

南美洲被动大陆边缘盆地形成于晚侏罗世-早白垩世冈瓦纳大陆的裂解，经历了前裂谷期、同裂谷期、过渡期、后漂移期4个阶段，发育了多套生储盖组合。

And Cretaceous in South Tibet was selected as the subject to investigate this relation in this article.

本文选择西藏南部白垩系为研究对象，对这一联系进行了针对性的研究。

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。
