Now we take these little bits and put them all together.

現在，我們把這些碎片拼在一起。

Or they could clump together and look like this.

或者，它們可以聚集在一起，看起來就像這樣。

From a microscopic perspective, these three rocks are all pretty much just like this, quartz.

從微觀角度看，這三塊石頭都差不多，都是石英。

那麼，為什麼它們看起來都如此不同呢？

And just like salt, quartz can actually dissolve in water at high temperatures.

就像鹽一樣，石英在高溫下也能溶於水。

Imagine this is a high-concentrated quartz soup, and the rocks below our Earth are practically made of this stuff.

想象一下，這是一種高濃度的石英湯，而我們地球下面的岩石實際上就是由這種東西構成的。

And so this high-concentrate, silica-rich bed starts filling in all the nooks and crannies of all the rocks below us.

於是，這個高濃度、富含二氧化硅的岩床開始填充我們腳下所有岩石的所有角落和縫隙。

If it gets oversaturated, then the silica will start to leave the bed in the form of solid crystals.

如果過飽和，二氧化硅就會開始以固態晶體的形式離開床層。

This rock is filled with chalcedony, microscopic needle-like silica crystals that grow in a radiating pattern.

這種岩石上佈滿了玉髓，玉髓是微小的針狀二氧化硅晶體，呈放射狀生長。

Imagine these open spaces were hyper-concentrated, super-hot silica soup.

想象一下，這些空地是超濃縮、超熱的硅湯。

If there are any little iron oxide impurities within the cracks of that microscopic silica, it'd be this color.

如果在這些微小的二氧化硅裂縫中有任何氧化鐵雜質，就會呈現出這種顏色。

If there are little pieces of copper in between, it may look like this.

如果中間有小銅片，可能會是這樣。

This is also a quartz vein, but what makes it different than this?

這也是一條石英礦脈，但它與此有何不同？

That's because the silica mixture that probably filled this crack may have been less concentrated.

這是因為填充這條裂縫的二氧化硅混合物的濃度可能較低。

Also, the quartz crystals in this vein are way larger.

此外，這個礦脈中的石英晶體要大得多。

White, brown, and even blue chalcedony can be found on Taiwan's east coast.

在臺灣東海岸可以找到白色、棕色甚至藍色的玉髓。

This is because Taiwan's coastal range used to be a group of volcanic islands.

這是因為臺灣的海岸線曾經是火山島群。

Back then, there was lots of hydrothermal activity going on, creating a bunch of silica-rich soup, which later cooled down to form chalcedony.

當時，熱液活動頻繁，產生了大量富含二氧化硅的湯汁，冷卻後形成了玉髓。

OK, this last one is a red jasper, and it isn't semi-transparent like chalcedony, but it's still made of microscopic quartz crystals.

好吧，最後這塊是紅碧玉，它不像玉髓那樣是半透明的，但它仍然是由微小的石英晶體組成的。

However, unlike chalcedony, they have a grain-like shape.

不過，與玉髓不同的是，它們的形狀像顆粒。

So for this rock, there must also be some oxidized iron in between the silica crystals, making it such a dark red color.

是以，這塊岩石的二氧化硅晶體之間一定還夾雜著一些氧化鐵，使其呈現暗紅色。

In Taiwan, all of these rocks are considered semi-precious gemstones, and all have unique names.

在臺灣，所有這些岩石都被視為半寶石，並且都有獨特的名稱。

Like this one is glutinous rice cake jade, and this one is chicken blood rock.

比如這個是糯米糕玉，這個是雞血石。

All around Taiwan, any rock with a unique appearance is given a special name and can have value.

在臺灣各地，任何具有獨特外觀的岩石都會被賦予特殊的名稱，並具有一定的價值。

So like this one, have you heard of rose stone?

那麼就像這個，你聽說過玫瑰石嗎？
