泰山石(shi)景(jing)觀石(shi)廠(chang)家(jia)分享什么是(shi)砂巖：

砂巖是指在(zai)碎屑巖中，粒度為2-0.05mm的碎層(ceng)物含量占50％以(yi)上，由膠結物膠結起來的巖石。

(1)砂(sha)巖的特點砂(sha)巖是(shi)一種沉積(ji)巖，主要(yao)由(you)砂(sha)粒膠(jiao)結而成(cheng)，其中秒里(li)粒含量(liang)要(yao)大(da)于(yu)50％。絕大(da)部分(fen)砂(sha)巖是(shi)由(you)石英(ying)(ying)或長石組成(cheng)的。砂(sha)巖按其沉積(ji)環境可劃分(fen)為石英(ying)(ying)砂(sha)巖、長石砂(sha)巖和巖屑砂(sha)巖三大(da)類。按巖石(礦物)類型分(fen)為石英(ying)(ying)秒巖(石英(ying)(ying)和各種硅質巖屑的含量(liang)占砂(sha)級巖屑總(zong)量(liang)的95％以(yi)上)和石英(ying)(ying)雜砂(sha)巖、長石砂(sha)巖(碎(sui)屑成(cheng)分(fen)主要(yao)是(shi)石英(ying)(ying))

中國盛(sheng)產(chan)砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)的(de)(de)兩(liang)個省(sheng)分為(wei)四(si)(si)川(chuan)省(sheng)、云南省(sheng)。四(si)(si)用(yong)(yong)(yong)省(sheng)盛(sheng)產(chan)的(de)(de)紅砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)、云南省(sheng)盛(sheng)產(chan)的(de)(de)黃(huang)秒巖(yan)(yan)(yan)(yan)(yan)享譽國內外。四(si)(si)川(chuan)砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)屬于(yu)泥砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)，其顆粒細膩，質地(di)較軟，非(fei)常適(shi)合作(zuo)為(wei)建(jian)筑裝飾用(yong)(yong)(yong)材，特(te)(te)別適(shi)合用(yong)(yong)(yong)作(zuo)雕刻用(yong)(yong)(yong)石，而(er)(er)且因為(wei)四(si)(si)川(chuan)的(de)(de)地(di)域地(di)質條件比較復雜，所以四(si)(si)川(chuan)的(de)(de)砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)品種(zhong)非(fei)常多。四(si)(si)用(yong)(yong)(yong)砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)的(de)(de)顏(yan)色(se)可以說(shuo)是(shi)中國豐(feng)富(fu)的(de)(de)，有(you)紅、綠(lv)、灰、白(bai)、玄、紫、黃(huang)、青等但是(shi)因為(wei)其材質相對較軟，并且交(jiao)通不便，礦區開采方式比較落后，所以四(si)(si)用(yong)(yong)(yong)砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)基本供給(gei)的(de)(de)是(shi)條板，無(wu)法(fa)提供1m2以上的(de)(de)大(da)板。云南砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)同(tong)四(si)(si)川(chuan)砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)一樣同(tong)屬泥砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)，顆粒細膩、質地(di)較軟，但是(shi)因為(wei)形(xing)成(cheng)的(de)(de)地(di)質地(di)域環(huan)境不同(tong)，云南砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)相對四(si)(si)川(chuan)砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)而(er)(er)言，紋理更漂亮，有(you)自己的(de)(de)風(feng)格特(te)(te)點，顏(yan)色(se)也很豐(feng)富(fu)，常見的(de)(de)有(you)黃(huang)木(mu)紋砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)、山水紋砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)、紅砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)、黃(huang)砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)、白(bai)秒巖(yan)(yan)(yan)(yan)(yan)和青砂(sha)(sha)(sha)巖(yan)(yan)(yan)(yan)(yan)。

砂巖主(zhu)要為沉(chen)積(ji)或沉(chen)積(ji)(輕)變質砂巖、巖頁巖，結構微細，具(ju)有良好的吸溫性(xing)能(neng)、表面粗(cu)獷，不少還具(ju)有原始的沉(chen)積(ji)紋理，用于裝(zhuang)飾更顯得出自然風貌。

(2)砂巖的用途砂巖由于(yu)其獨特(te)的紋理效果(guo)，是雕刻的較佳材料，能(neng)充分展示雕刻所表(biao)現的主題。砂巖也(ye)可以用于(yu)建(jian)筑(zhu)的室內(nei)外裝飾(shi)，尤(you)其特(te)別(bie)適用于(yu)別(bie)墅(shu)裝飾(shi)，它還常被運用在古樸、莊重、粗獷(guang)、原始的建(jian)筑(zhu)裝飾(shi)環境中(zhong)。
