水晶之乡——东海水晶是结晶比较完美的透明石英,其化学成分是二氧化硅,它比钢铁还硬,同时还能耐1700℃以上的高温,不含杂质的水晶无色透明,如果有铁、锰、钛等杂质混入,则呈现出不同的颜色,水晶是一种古老而常见的宝玉,它与珍珠、玛瑙和玉石合称为我国的“传统四宝”。江苏省连云港市的东海县是我国著名的水晶产地,据地质部门调查,这里水晶的分布面积达1200平方千米,储量在400万吨以上,多年平均开采量在600吨左右,约占全国水晶产量的1/2,该县十几个乡镇都有水晶产出,当地人在翻地、盖房以及开沟修渠等活动
Crystal Hometown - East China Sea Crystal is the more perfect crystalline transparent silica, its chemical composition is silica, it is also harder than steel, but also resistant to high temperatures above 1700 ℃, impurities free crystal colorless and transparent, if iron , Manganese, titanium and other impurities mixed, then showing a different color, crystal is an ancient and common gem, with pearl, agate and jade collectively known as China’s “traditional four treasure.” Donghai County, Lianyungang City, Jiangsu Province, China is well-known crystal origin, according to geological survey, where the crystal distribution area of 1,200 square kilometers, reserves of 4 million tons, the average annual production of about 600 tons, accounting for the national crystal The output of 1/2, the county more than 10 towns have crystal output, locals in the land, housing and ditching canal and other activities
