This is my master's thesis I basically did a uh description of uh tried tried to be as simple as I could to explain uh Hualien's geology hopefully you could pick this up in a year or so but so oh you mean like the book not the not the concept no no this book I still haven't picked up I still haven't picked up on the concept this is like magnetic yeah this is a this is called Serpentinite Taiwan Jade comes from this rock it was formed in the lenses in the veins almost you know like veins in your skin in a serpentinite rock it's magnetic because it's been metamorphosed this used to just be some lame or kind of cool igneous rock kind of cool lava rock and this got basically cooked again and squeezed under intense pressure and the black stuff turned into the mineral magnetite so it's magnetic magnetic which is just iron and oxygen and then the green stuff the green stuff turned into either serpentine this this green mineral which is looks very similar it's a little shinier looks very similar to nephrite but it's not see-through and it's not as hard this is like basically an evolved rock I wanted to talk about like the little bit uh different rock like so these rocks are all from Taiwan yes but they look very different could you just walk me through like just geographically like the rocks that are from different regions of Taiwan if we were to we know Jade so this is like only found in Hualien not found at Jade Mountain Marble Eastern Taiwan Hualien and Taitung這是我的碩士論文 我基本上是在描述花蓮的地質 儘量簡單的解釋 希望你能在一年左右的時間內瞭解這本書 但你的意思是說這本書不是概念?蛇紋石之所以有磁性,是因為它經過了變質處理,以前只是一些蹩腳的或酷酷的火成岩,一種酷酷的熔岩,基本上又被煮熟了,在高壓下擠壓,黑色的東西變成了礦物磁鐵礦,所以它有磁性,磁性就是鐵和氧氣,然後綠色的東西,綠色的東西變成了蛇紋石,這種綠色的礦物看起來非常相似,有點光澤,看起來和軟玉非常相似,但它不透,也不像軟玉那麼硬。我想談談不同的岩石,這些岩石都來自臺灣,但它們看起來很不一樣,你
