The Romans were very fond of Carnelian.

罗马人非喜欢卡 Carnelian。 ：Carnelian 翻译为“角闪石”或“红碧石”，但根据上下文，如果指的是宝石中的“红碧石”，则更见翻译为“红碧石”。此处未进一步具体化，以保持原文的简洁性。

She decided to test a rock called pitchblende.

她决定测试一种叫做沥闪石的岩石。

When Marie tested the pitchblende, she found it gave off even more rays than uranium alone!

当 Marie 测试沥闪石时，她发现它发出的射线比单独的铀还要多！

She tried to separate the polonium from the pitchblende—but she failed.

她试图将钋从沥闪石中分离出来——但她失败了。

The pitchblende contained another mysterious metal that was giving off rays.

Most of the broad summit is comparatively level and thick sown with crystals, quartz, mica, hornblende, feldspar, granite, zircon, tourmaline, etc., weathered out and strewn closely and loosely as if they had been sown broadcast.

宽阔的峰顶大部分较为平坦， 密布着晶、石英、云母、角闪石、长石、花岗岩、锆石、电气石等，经风化后，密布、松散， 犹如播种。

Listening, admiring, until late in the afternoon I compelled myself to hasten away eastward back of rough, sharp, spiry, splintery peaks, all of them granite like the Cathedral, sparkling with crystals—feldspar, quartz, hornblende, mica, tourmaline.

边听边欣赏，直到下午晚些时候，我才强迫自己加速向东撤退，回到粗糙、尖锐、尖尖、多裂的山峰，所有这些山峰都像大教堂一样的花岗岩，闪闪发光的晶体——长石、石英、角闪石、云母、电气石。
