Not sure what you mean by 合成, but granite is an igneous rock and is formed
from magma, so 合成 happened long time ago.
Granite is a natural source of radiation, like most natural stones. However,
some granites have been reported to have higher radioactivity thereby
raising some concerns about their safety.
Some granites contain around 10 to 20 parts per million of uranium. By
contrast, more mafic rocks such as tonalite, gabbro |

By the way, the picture of blue pearl above is not 大理石, it is granite. 大
理石 is marble. They are complete different kind of rock. Granite is igneous
rock, marble is metamorphic rock.
唉！ |

如果我选这个颜色的countertop, 那么地板和墙的颜色选什么好看呢？ 谢谢指点！

发帖数: 4125 | 6 Granite is much more abundant than marble and widely distributed throughout
the entire earth. That is why granite is the cheapest natural stone you can
buy (also the reason why builder use it in all the house because the cost)
Granite and marble are complete different kind of product.
Granite is igneous rock, marble is metamorphic rock.
Marble is much more pretty than granite as far as the counter top is
concerned. |

昨天老公说“这十年把你耽误了”因为过去的9年，我跟老公海归，现在回来了，以前
同事比我的职务、工资都高。我倒是觉得这些年非常值得，首先，孩子是自己一手带大
，没有老人和保姆，孩子是自己想要的样子；第二是孩子们在中国的9年使他们学会了
中文读写，也让他们懂得珍惜美国这里的好处；第三是自己做了几年小生意，虽然没有
像别人期望的“挣大钱”，但是了解了很多不同的东西，比如从老板的角度怎么看问题
，所谓“子非鱼”，现在回了美国，发现周围的老中脑子里的中国都是他们出国前的故
事和这边媒体的一面之词，还觉得自己看明白了中国。

这些天板上好多讨论生一个还是生两个的问题
看到很多妈妈说，生两个是为了给孩子一个伴，很是sweet
我是非独生子女，很庆幸有妹妹这个伴
不过我想讲讲自己从小到大的经历，不代表任何人，纯讲故事
我爸妈都是普通市民，我们家就是普通小市民家庭
我们那个generation，很多人都是独生子女
但是爷爷想要孙子，所以爸妈生了第二胎，不过是个妹妹
所以我们家就2孩子，
记得那个时候，同一单位的住在一起，家家收入差不多，
房子也差不多，所以从小我就跟妹妹share房间，share床
穿差不多的衣服，爸妈也尽力给我们提供必需的条件
然后也积极为我们的将来省钱，我想我爸妈应该是我周围的父母中比较辛苦的
吃的穿的也基本上比别人家会差一点，这个还是看的出来的
我从小羡慕其他的朋友有自己的房间，觉得有自己的天地，
可惜我只有自己的一个抽屉
还经常被妹妹撬开偷看我的日子，从此以后我就不写日记了
我跟妹妹小时候关系其实并... 阅读全帖 |

锆石。锆石会把铀元素掺入晶格，但是强烈排斥铅。因此后来在锆石里发现的铅就是形

http://en.wikipedia.org/wiki/Uranium-lead_dating
Uranium-lead dating is usually performed on the mineral zircon (ZrSiO4),
though it can be used on other minerals such as monazite, titanite, and
baddeleyite.
The zircon mineral incorporates uranium and thorium atoms into its
crystalline structure, but strongly rejects lead. Therefore we can assume
that the entire lead content of the zircon is radiogenic.

Radiometric dating
Geologists use radiometric dating to estimate how long ago rocks formed, and
to infer the ages of fossils contained within those rocks.
Radioactive elements decay
The universe is full of naturally occurring radioactive elements.
Radioactive atoms are inherently unstable; over time, radioactive "parent
atoms" decay into stable "daughter atoms."
When molten rock cools, forming what are called igneous rocks, |
