1.灰岩；石灰岩
limestone is a whitish-coloured rock which is used for building and for making cement.
e.g. ...highlimestone cliffs...
高耸的石灰岩峭壁
e.g. The locallimestone is very porous.
当地的石灰岩有很多孔隙。
1. 石灰石：Columbia)和阿尔帕塔省(Alberta)交界处时,把头贴着窗边,向下俯视那一片连one),石灰石(limestone)等构成的岩样群山. 从九千到一万米的飞行高度上看飞机到达卡加利(Calgary)时,正是当地时间下午三点. 阳光正灿烂地照耀
2. 石灰岩：描 述: 石灰岩 (limestone) 简称 灰岩 以方解石为主要成分的碳酸盐岩. 有时含有白云石、粘土矿物和碎屑矿物,有灰、灰白、灰黑、黄、浅红、褐红等色,硬度一般不大,与稀盐酸反应剧烈. 结构较为复杂,有碎屑结构和晶粒结构两种.
3. 灰岩：相似之处:与美国相似的是,加拿大石材产业也由少数厂商所主宰,尤其是源於魁北克(Quebec)的几家大厂,如Granicor Inc,Granite Bussiere Inc,Lacroix & fils等,尤其花岗石(Granite),石灰岩(limestone)等大理石以外之石种更为明显;

水渗透石灰石则形成洞穴。
We may burn limestone to obtain lime.我们可以通过烧石灰石来得到石灰。
limestone is often used in building construction.石灰岩常用于建筑.
Cement is made from limestone.水泥是由石灰石制成的.
The limestone is sufficiently fissured for tree roots to have breached the roof of the cave.石灰岩上有许多缝隙，故而树根能从岩洞顶部长出来。
Between the white limestone and the greyish pink limestone is a thin bed of clay.在白色石灰石和粉灰色石灰石之间是一层薄薄的黏土。
The large limestone caves are also quarried for cement.同时还在这些大石灰岩洞里开采水泥原料。
The local limestone is very porous.当地石灰岩渗透性很强。
The limestone must be calcined in such a way.石灰石必须煅烧到这样地步.
Calcitic limestone is mainly CaCo 3 with relatively small amounts of impurities.方解石灰岩,主要是由CaCo3和少量的杂质所形成.
A thin, resistant limestone escarpment is present just basinward.薄层状的坚硬的石灰岩山崖正好位于靠盆地一侧.
The limestone, sandstone and shale of this area were soft.这个地区的灰岩 、 砂岩和页岩都是很柔软的.
The mud is interrupted by numerous thin beds of limestone.泥质物被许多薄层灰岩所隔开.
There the soil is from weathered limestone soil or loess.那里的土壤是经过风化作用的石灰石土壤或黄土.
The answer is the same if the limestone overlays the sandstone.当灰岩盖在砂岩上时,系数是相同的.
The channel is overlain by siltstone and lenticular beds of limestone.河道上面覆盖着粉砂岩和石灰岩透晶体.
limestone had been carved away.石灰石已被开采运走.
