RI039 Kimberlite

Class: 4C
Name: Wong Crystal Ching Lam
Year: 2014 – 2015
地質年代:(化石) (岩石)

化學組成, 鍵及結構:(礦物)

 

Geological Age: (Fossil) (Rock)

Chemical composition, bonding and structure: (Mineral)

 

形成:(岩石) (礦物)

原生物:(化石)

金伯利岩由岩地球的地幔,由火山管道帶到地殼。它在這些火山管道中慢慢冷卻,其中所述熔融礦物成長為大晶體。

Formation:(Rock) (Mineral)

Living Specimens: (Fossil)

Kimberlite is formed within the earth’s mantle and is brought to the earth’s crust by means of volcanic pipes leading from the mantle to the surface. It cools slowly in these volcanic pipes where the molten minerals grow into large crystals

特性:

金伯利岩是一種雲母橄欖岩,其最豐富的礦物成分是橄欖石。其他豐富的礦物質包括金雲母。

Properties:

It is a mica peridotite, and its most abundant mineral constituent is olivine. Also has other abundant minerals include phlogopite mica.

用途:(岩石) (礦物)

有些金伯利岩含有鑽石。它是鑽石的最主要的來源之一。金伯利岩管是用來產生豐富的沖積和殘坡積砂礦金剛石礦床。

Application: (Rock) (Mineral)

Kimberlite may contain diamond. It is one of the most important source of primary diamonds. Kimberlite pipes are used to produce rich alluvial or eluvial diamond placer deposits

分佈:(岩石) (礦物)

分佈於南非,加拿大,美國阿肯色州,也會在百萬年前曾經是火山的地區發現。

Distribution: (Rock) (Mineral)

It is found in South Africa, Canada, Arkansas , also found in areas that were once volcanic many millions of years ago.
