介紹
太武山的地質特色
金門的誕生是在距今兩億至一億年前的燕山運動隆起，喜馬拉雅運動上升之中，發育出來的花崗岩，經風化，裸露出地面而成丘陵，如太武山（高253公尺），五虎山（127公尺），其構成主要罕見的基盤岩石以花崗片麻岩所組成，在太武山之南側，出露岩石以花崗片麻岩為主，山之北側則以花崗岩較多.
這個地質寶會介紹在台灣罕見的岩石以花崗片麻岩。根據您所觀察到的您會辨識岩石以花崗片麻岩。
Intoduction
Unique Geological Features of Taiwu Mountain
Kinmen surfaced one to two billion years ago due to the Yanshan and Himalayan plate movement, and is composed mostly of granite. Taiwu Mountain (253 meters high) amd Wuhu Mountain (127 meters high) are both formed by granite gneiss and gneiss, which are rarely seen in Taiwan. The south part of Taiwu Mountain is mostly granite gneiss, and the north side is large of granitic composition.
Now granite is mostly found in the continental crust of the Earth, The continental crust is the layer of granitic, sedimentary, and metamorphic rocks which form the continents. Granite and granite gneiss are mostly found around the actual landmasses especially in North America. However, an island on the other side of the Pacific, just a mere two kilometers from mainland China, lies Kinmen, which has an abundance of granite and granite gneiss, which makes this a geologically unique place where you can observe an anomaly of rocks since the main island of Taiwan is mostly siltstone, basalt, shale, and limestone, but Kinmen takes on a whole new geological face.
In this Earth Cache you will visit a total of six places along the trail and based on your observations identify granite and gneiss and draw conclusions based on those observations, and try to figure out why this anomaly of rocks occurs here.

岩石
花崗岩
花崗岩岩漿並沒有經火山噴發出來，而是在地下冷卻凝固，後來經國地殼隆升和侵蝕才露出地面的
花崗片麻岩
花崗片麻岩是由堅硬的砂岩或花崗岩經高壓，溫度（攝氏約600度以上) 而發生化學變化，而形成黑白兩種新礦物，岩面上的黑白斑點，一顆顆都是礦物結晶，有如撒上芝麻。白色斑點可能是岩英，正長石，白雲母等礦物；黑色斑點則多半是黑雲母。
Rocks
Granite:
Granite is formed when magma is cooled deep in the earth's crust; uplifting and erosive forces then cause the granite to surface.
Granite Gneiss:
Granite gneiss is formed when granite is subjected to high pressure and heat (600 degrees Celsius and above), and is transformed into new types of minerals. The black and white sesame-like specs on the surface of granite gneiss are minerals. The white specks could be quartz, orthoclase, muscovite, etc. The black specks are mostly biotite.

花崗岩及花崗片麻岩的差別
組成
花崗岩主要礦物成分是石英及長石，花崗片麻岩只要礦物成分是雲母及長石。 另外，花崗岩是火成岩，花崗片麻岩則是變質岩。
顏色
因為花崗岩主要成分是石英及長石所以石頭顏色為紅，粉紅，灰，白這些顏色。花崗片麻岩雖然有類似的成分但是顏色比較會像一半是深粉紅或灰一半是淺粉紅或灰
紋理
花崗岩非常粗糙至極粗糙，花崗片麻岩比較中等粗糙
用途
花崗岩得天獨厚的物理特性加上它美麗的花紋使他成為建築的上好材料，素有「岩石之王」之稱；在建築中花崗岩從屋頂到地板都能使用，人行道的路緣也是，若是把它壓碎還能製成水泥或岩石填充壩。 許多需要耐風吹雨打或需要長存的地方或物品都是由花崗岩製成的。 花崗片麻岩比較偏擺飾用途，用在地板，墓碑，石碑等。
Differences between Granite and Granite Gneiss
Composition
Granite is the kind of rock with the composition of feldspar and quartz while Gneiss has mica and quartz. Also, Granite is an igneous rock whereas Gneiss is a metamorphic rock.
Color
Granite is composed mainly of feldspar and quartz so these mineral compositions usually give granite a red, pink, gray, or white color with dark mineral grains visible throughout the rock. Gneiss, despite being composed of similar minerals as granite, due to its exposure to high temperatures and its classification as a metamorphic rock, its colors vary from alternating dark and light (white, pink or grey) bands.
Texture
Granite is coarse to very coarse-grained whereas Gneiss is is a medium- to coarse-grained.
Uses
Granite is used in buildings, bridges, paving, monuments, and many other exterior projects. Indoors, polished granite slabs and tiles are used in countertops, tile floors, stair treads and many other design elements. Gneiss is an ornamental stone and has many uses as a building material such as flooring, ornamental stones, gravestones, facing stones on buildings and work surfaces.

登記條件：
為了登 [Found It]你必須走這座山的不同步道， 總共有六個步驟。當你到了每一個步驟時，你會看到一些特別的岩石，在觀察之中，要回答下列的問題並寫email跟我說答案：
1. 第一個步驟就是此寶的座標。到了後跟我說你看到什麼樣的岩石
2. 再來走去其他的步驟然後跟我說你看到的是什麼
3. 根據你的觀察，你認為這些岩石是屬於花崗岩還是花崗片麻岩？你為什麼這麼認為？
4. 在每一個步驟，你覺得那裡有比較多的花崗岩還是花崗片麻岩？為什麼這樣說呢
5. 去完所有的步驟之後你覺得為什麼一些地區有更多或者更少的花崗岩或者花崗片麻岩?
6. 去完所有的步驟之後你覺得為什麼金門這個島嶼為什麼說會有這麼多的這種岩石呢?
7. (非必需的) 可以把你或者你的GPS的照片貼上去。
請注意：一些部分得爬石頭，而且有可能會有野生動物及有毒植物在，所以務必走已鋪好的步道，還有千萬不要隨意去碰植物或者摸看不到的地方! 希望各位喜歡此地理寶還有在享受風景之餘可以走一下歷史路線！
Logging Requirements
You will need to walk along the various trails of this mountain, visiting all six waypoints. As you arrive at each of the waypoints, you will come to various rock formations. In order to log this cache you must email me with the answers to the following:
1. Go to posted coordinates (Stage 1) and observe the rocks there. Based on your observations, are the rocks more likely to be Granite or Gneiss or a combination of both.
2. Go to Stages 2 through 6 and observe the rocks there and tell if the rocks are more likely to be Granite or Gneiss or a combination of both.
3. Based on your observations at each of the Stages, how did you come to your conclusions of which type of rock(s) was/were there?
4. At each of the waypoints visited, was there a bigger concentration of Granite Rocks or a bigger concentration of Gneiss, or was it even? How did you come to your conclusion?
5. After visiting all six waypoints and based on your observations and conclusions, why do you think some parts of the mountain had a bigger concentration of Granite Rocks and a smaller concentration of Gneiss Rocks or vice versa?
6. After visiting all six waypoints and based on your observations and conclusions， as well as what you learned from this cache page, what could be the cause of why Kinmen has such a high concentration of granite and/or granite gneiss?
7. (Optional) Post a picture of you (face can be blurred out) and your GPS at one of the Stages.
Please Note: Some parts along the trail require you climb up rocks and walk along trails where poisonous plants and various animals/insects may be present. Please stick to the main paths that have been laid out and pay attention to where you are sticking your hands. I hope you enjoy this Earth Cache and taking a walk through history!
