松花石是数亿年前海相运动过程中海底的淤积细泥,经过沉积、覆盖、压制等物理过程形成的坚硬的沉积型微晶石灰岩。它的生成时间距今约8.8亿年,国内有名的砚石端石,歙石,澄石在此时期均没有出现,其基本的矿物质成分是:方解石、石英、云母、黏土以及少量的金属矿物质等。且松花石无毒、无味、无辐射,色泽丰富,质地细腻,矿藏稀少,既能用以雕刻实用和观赏砚台,还可作为名贵的建筑装饰及加工工艺品用料。在民间更是盛传着可做镇宅之宝之说。
Songhua stone is the deposition of fine silt in the seafloor during the marine movement hundreds of millions of years ago. It is a hard sedimentary-type microcrystalline limestone formed through physical processes such as sedimentation, covering and pressing. Its generation time is about 880 million years ago. The famous rock stone, stone and stone in this period are not found in this period. Its basic mineral composition is: calcite, quartz, mica, clay and a small amount of metal Minerals and so on. And Songhua non-toxic, tasteless, non-radiation, rich color, delicate texture, mineral deposits scarce, both for carving practical and ornamental ink stone, but also as a valuable architectural decoration and processing crafts materials. In the private sector is even rumored to do the house of the treasure.
