| 形成：
原生物： 它是由入侵性火山作用的過程中形成的。當裂縫發展到地殼，時間流逝後, 它延伸到地幔。岩漿通過裂縫上升。途中，它冷卻和凝固。在冷卻過程中，結晶發生在岩石上。礦物的集合體形成的岩石，被稱為火成岩。

Formation:
Living Specimens: It is formed during the process of intrusive vulcanicity. When cracks develop in the crust. After time passes, it extends to the mantle. Magma rises up through the cracks. On its way, it cools and solidifies deep within the earth’s surface. During the cooling process, crystallization takes place in rocks. The aggregate of minerals forms rock, called igneous rock. |
| 特性：
它包含三個礦物質：雲母（黑），石英（灰色）和長石（粉紅色）。因為它們是形成在地球表面深處，需要緩慢冷卻過程。正因為如此，它們具有比噴出岩更多的時間發展成粗粒度的大小。 |
Properties:
It contains three minerals: mica(black), quartz(grey) and feldspar(pink). Since they are formed deep within the earth surface, slow cooling process is required. Because of this, they have much more time than extrusive rock to develop into coarse-grained size. |
| 用途：
許多工人使用花崗岩作為一種建築材料, 用於建房。 |
Application:
Ｍany workers used granite as a kind of construction materials for building houses. |
| 分佈：
超過35％的岩石是在露頭在香港。它很容易在雙方的維多利亞港，屯門，青山，大嶼山，西貢等地區發現 |
Distribution:
Over 35% of rocks are at outcrops in Hong Kong. It is easily found in the area of the both sides in Victoria Harbour, Tsun Mun, Castle Peak, Lantau Island, Sai Kung etc. |
