五光十色的地球上有许多色彩斑烂的石头。它们有花的艳丽,云的袅娜,钢的坚劲,因此吸引了人们极大的兴趣,成为地学研究的对象。有一种形状独特的石头,地学工作者给这种石头取了个特定的名字,叫做“砾石”。说起砾石,人们自然地要想起那染满烈士鲜血的 “雨花石”;想起那蔚为壮观的“风动石”和巍峨庐山上的冰川漂砾!它们或剔透玲拢;或晶莹如玉;或温润如脂。小者有如珠矶;大者胜过广厦。这些砾石身世不凡,在岩石家族中独树一帜,堪称石中精英!它们都有一付浑圆的外貌,然而孕育它们成形的却是千古的地质时代;岩石则是它们的亲生母亲。这都是靠了大自然的力量。 There are many colorful stones on the colorful world. They have the beautiful flowers, the beautiful clouds and the strength of the steel, thus attracting people’s great interest and becoming the object of geosciences research. There is a unique shape of the stone, geology workers to give this stone a specific name, called “gravel ”. Speaking of gravel, people naturally think of the “stone” stained with martyr blood; think of the magnificent “Pneumatic Stone” and glacial boulders in the towering Lushan Mountain! Crystal jade; or moist as fat. The smaller is like a pearl; the bigger is better than the mansions. These gravel extraordinary life, unique in the rock family, called the elite stone! They have a pair of rounded appearance, but the birth of them is forming the era of eternity; rock is their biological mother. It all depends on the power of nature.
