Class: 5D
Name: Reese Chan
Year: 2017 – 2018

 

地質年代:(化石) (岩石) N/A

化學組成, 鍵及結構:(礦物)

藍閃石、柘榴子石、綠簾石、石英、白雲母、綠泥石、黑硬綠泥石、榍石和磷灰石等

Geological Age: (Fossil) (Rock) N/A

Chemical composition, bonding and structure: (Mineral)

Amphibole, sphagnum stone, epidote, quartz, muscovite, chlorite, black hard chlorite, vermiculite and apatite

形成:(岩石) (礦物)

藍閃石片岩是由片岩原岩的低溫高壓(藍片岩相)區域變質作用形成的。 它通過在高壓和低溫下形成類似成分的玄武岩和岩石的變質作用形成,大約相當於深度15至30公里和200至500°C

原生物:(化石) N/A

Formation: (Rock) (Mineral)

Blueschists are formed by low temperature, high pressure (blueschist facies) regional metamorphism of basaltic protoliths. Blueschist forms by the metamorphism of basalt and rocks with similar composition at high pressures and low temperatures, approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C

Living Specimens: (Fossil) N/A

 

特性:

藍閃石片岩為一種粗粒而緻密組織的岩石,它含有斑狀變晶的黑色角閃石,岩基為粉紅色,是由細粒的柘榴石、綠簾石及石英所組成。(藍閃石55%、柘榴子石17%、綠簾石13%、石英12%、白雲母1.5%、綠泥石0.7%、榍石0.6%、及痕量(tr.)的黑硬綠泥石)。

Properties:

Glaucophane Schist is a coarse-grained and densely organized rock that contains a speckle-like metamorphic black amphibole. The rock base is pink and consists of fine-grained garnet, epidote and quartz. (Ultrachromite 55%, eucalyptus stone 17%, epidote 13%, quartz 12%, muscovite 1.5%, chlorite 0.7%, vermiculite 0.6%, and trace (tr.) black hard green mud stone).

分佈:(岩石) (礦物)
西北部的土耳其擁有兩個主要的構造單元,即龐蒂德和Anatolides,由伊茲密爾 – 埃爾津詹縫合線分開。 Anatolides是Taurides變形的北部延伸部分,由幾個區域組成。 更南方的阿菲永地帶是一個早古生代到馬斯特里希特·陶里德的貨架式序列,它依賴於Menderes地塊的片麻岩。

 

 

 

Distribution: (Rock) (Mineral)

North-west Turkeyencompasses two major tectonic units, the Pontides and the Anatolides, separated by the Izmir-Erzincan suture. The Anatolides, the metamorphosed northern extension of the Taurides, consist of several zones. The more southerly Afyon Zone is an Early Palaeozoic to Maastrichtian Tauride shelf-type sequence which rests on gneisses of the Menderes Massif.

知多一點點:

1962年,美國地質調查局的埃德加貝利將“藍片岩”的概念引入變質地質學科。 他精心構造的定義確定了產生這種變質作用的壓力和溫度條件。

 

More to learn:

In 1962, Edgar Bailey of the U.S. Geological Survey introduced the concept of “blueschist” into the subject of metamorphic geology. His carefully constructed definition established the pressure and temperature conditions which produce this type of metamorphism.
