Chemical composition, bonding and structure:

Pyroxene, silica, alumina, mica, feldspar, quartz

1.      當岩漿上升到地殼

2.      因為溫度下降，而進行冷卻過程，岩漿在地殼下冷卻和凝固

3.      在冷卻期間，地殼下的岩漿會結晶

4.      因為在地殼下冷卻，溫度比地面高，岩漿冷卻得較慢，而有較大的結晶體

5.      這些結晶體最後組合並形成石頭，也形成了花崗岩

1.      When magma rises through the crust

2.      The temperature decrease, and cooling process may take place, magma then will cools and solidifies within the crust

3.      During the cooling process, crystallization will take place in magma

4.      Because is cooling within the crust, the temperature is hotter than the earth surface, magma cools and solidifies very slow, and have large crystals

5.      Those minerals aggregate and forms rocks, also form granite

質地堅硬緻至，抗風化，強度高，耐腐蝕，耐磨損，吸水性低，不耐熱，由礦物晶體形成的，晶體結構，晶體是聯鎖式排列的，可以是深色/淺色，沒有化石，有大的結晶體

Well-jointed, Anti-weathering, high strength, corrosion-resistant, wear-resistant, low water absorption, not, heat-resistant, made of mineral crystals, with crystalline structure, crystals are interlocking, can be both light and dark colour

, no fossil, contains large crystals

用作建築物料

Used as building materials

世界有許多國家都有出產花崗岩，例如 中國，加拿大，義大利，南非等

就香港而言，花崗岩是香港最常見的火成岩，露出的佔35%。能在大嶼山東部，維多利亞港，青山，大欖，沙田，大埔找到

In lots of nations in the world also have granite, like China,

Canada, Italy, South Africa etc.

In Hong Kong, granite is the most comment, and occupies 35% of the outcrop, they occur in, eastern Lantau Island, Victoria Harbour, Castle Peak, Tai Lam, Sha Tin, Tai Po
