化學組成, 鍵及結構：(礦物)

Chemical composition, bonding and structure: (Mineral)

大理石是有由石灰岩凝結而成，它是由風化破壞了石頭然後沉積為沉積物，當沉積物被掩埋時，它被壓實和接合形成沉積岩（石灰岩）。變質岩（大理石）通常位於岩漿接觸出岩的區域，在火山和地殼之間發生，當岩石受到高溫和高壓時，變質作用改變岩石的組織和礦物組成，因高溫會使岩石融化並重新凝結成新的岩石，形成變質岩（大理石）。

原生物：(化石)

Marble is formed by limestone which is a sedimentary rock, it is due to weathering breaks down the rock that is transported and deposited as sediment, when sediment is buried, it compacted and cemented to form sedimentary rock (limestone). Metamorphic rock (marble) usually located at the zone where the magma intrusion touches the existing rock, where volcanism and crustal movement occur, when the rock is subject to high temperature and high pressure, metamorphism changes the texture and mineral composition of the rock, since high temperature can make the rock crystals melt and recrystallize into new rock, forming metamorphic rock (marble).

Living Specimens: (Fossil)

它有不同的組織和化學成分，是結晶性的，有光澤的外觀。

It have different texture and chemical composition, is it crystalline and it has shiny appearance.

大理石是重要的石材，經過磨光後，它有很多不同的用途。例如：建築物的地板和牆或者是紀念性建築物的雕像，甚至雕刻成藝術品，像文具和燈具。還有，在開採和加工過程後留下的碎石可用於塑料，橡膠等行業的填料。

Marble is an important stone, after polishing, it has lots of different uses. For examples, the floor and wall of building or the statue of monumental building and even carved into a craftwork, such as stationery and lamps. Also, the crushed stone left after mining and processing can be used for fillers in plastics, rubber and other industries.

·         由較純的碳酸鹽岩石形成的大理岩中，方解石，白雲石佔90％以上，有時可含很少的石墨，白雲母，磁鐵礦，黃鐵礦等，在低溫高壓下方解石可轉變成文石

In marbles formed from relatively pure carbonate rocks, calcite and dolomite account for more than 90%, and sometimes they can contain few graphite, muscovite, magnetite, pyrite, etc. Under low temperature and high pressure, the rock can be transformed. Cheng Wenshi;The marbles formed from tantalum-bearing carbonate rocks may contain talc, tremolite, actinolite, quartz, etc. at medium and low temperatures. Diopside, orthopyroxene, and forsterite may be present at high temperatures. , Wollastonite, periclase, etc., In the high temperature and low pressure conditions, there may appear granulite, calcareous olivine, feldspar and so on;Marbles formed from argillaceous carbonate rocks may contain serpentine, chlorite, epidote, eucalyptus, fushan, biotite, acid plagioclase, microcline, etc. at medium and low temperatures. In high temperature, it may contain sibisite, Calcium Almanite, Cericite, Phlogopite, Spinel, Apatite, Basic plagioclase, and Orthoclase.

大理石裡的方解石和白雲石的含量一般大於50％，有的達99％。遇鹽酸反應產生二氧化碳。

The content of calcite and dolomite inside the marble is generally greater than 50%, and some are up to 99%. Reaction with hydrochloric acid to produce carbon dioxide
