花崗巖成分：

花(hua)崗(gang)巖(yan)(yan)(yan)是巖(yan)(yan)(yan)漿在(zai)地下深處經冷凝而(er)形(xing)成(cheng)的(de)(de)深成(cheng)酸(suan)性火成(cheng)巖(yan)(yan)(yan)，部分花(hua)崗(gang)巖(yan)(yan)(yan)為(wei)(wei)巖(yan)(yan)(yan)漿和(he)沉積(ji)巖(yan)(yan)(yan)經變質而(er)形(xing)成(cheng)的(de)(de)片麻(ma)巖(yan)(yan)(yan)類或混(hun)合巖(yan)(yan)(yan)化的(de)(de)巖(yan)(yan)(yan)石(shi)(shi)(shi)(shi)(shi)。花(hua)崗(gang)巖(yan)(yan)(yan)主(zhu)要(yao)組成(cheng)礦物為(wei)(wei)長(chang)石(shi)(shi)(shi)(shi)(shi)、石(shi)(shi)(shi)(shi)(shi)英(ying)(ying)、黑白云母等，石(shi)(shi)(shi)(shi)(shi)英(ying)(ying)含量是10%～50%。長(chang)石(shi)(shi)(shi)(shi)(shi)含量約總量之2/3，分為(wei)(wei)正長(chang)石(shi)(shi)(shi)(shi)(shi)、斜(xie)長(chang)石(shi)(shi)(shi)(shi)(shi)(堿(jian)石(shi)(shi)(shi)(shi)(shi)灰)及微斜(xie)長(chang)石(shi)(shi)(shi)(shi)(shi)(鉀(jia)堿(jian))。不同品種(zhong)的(de)(de)礦物成(cheng)份不盡(jin)相(xiang)同，還可能(neng)有含輝石(shi)(shi)(shi)(shi)(shi)和(he)角(jiao)閃石(shi)(shi)(shi)(shi)(shi)。

甘肅花崗巖質地堅(jian)硬(ying)(ying)，難(nan)被酸堿或風化作用(yong)(yong)侵蝕(shi)，常被用(yong)(yong)于建(jian)筑物(wu)的材料(liao)。花(hua)崗(gang)巖(yan)(yan)(Granite)的語源是拉丁文的granum，而漢字名詞花(hua)崗(gang)巖(yan)(yan)則是由日本人翻譯(yi)而來。明治初期的辭典(dian)與(yu)地質學書籍(ji)將Granite翻譯(yi)作花(hua)崗(gang)巖(yan)(yan)或花(hua)剛(gang)巖(yan)(yan)。花(hua)形容這種巖(yan)(yan)石有(you)美麗的斑紋，剛(gang)或崗(gang)則表(biao)示(shi)這種巖(yan)(yan)石很(hen)堅(jian)硬(ying)(ying)，也(ye)就是有(you)著(zhu)花(hua)般斑紋的剛(gang)硬(ying)(ying)巖(yan)(yan)石的意思(si)。

巖石成因：

在(zai)成因方(fang)面，有(you)人認(ren)為花(hua)崗(gang)巖(yan)(yan)(yan)是(shi)地殼深處(chu)的花(hua)崗(gang)巖(yan)(yan)(yan)漿(jiang)經(jing)冷(leng)凝結晶或由玄武巖(yan)(yan)(yan)漿(jiang)結晶分異(yi)而成，也有(you)人認(ren)為是(shi)深度變質(zhi)和交代(dai)作用(yong)所引(yin)起的花(hua)崗(gang)巖(yan)(yan)(yan)化(hua)作用(yong)的結果。許多有(you)色金屬(shu)礦(kuang)產如(ru)銅、鉛、鋅(xin)、鎢、錫、鉍(bi)、鉬等(deng)(deng)，貴金屬(shu)如(ru)金、銀等(deng)(deng)，稀有(you)金屬(shu)如(ru)鈮、鉭(tan)、鈹(pi)等(deng)(deng)，放射性元素如(ru)鈾(you)、釷等(deng)(deng)，都與花(hua)崗(gang)巖(yan)(yan)(yan)有(you)關。花(hua)崗(gang)巖(yan)(yan)(yan)結構均勻，質(zhi)地堅硬(ying)，顏色美觀，是(shi)優質(zhi)建筑(zhu)石料。
