 Introduction   

 Generally referred to stone people usually associate it with: Nanjing Yuhuatai, all thought that the stone is produced in Yuhuatai area, in fact, this is only the people's misunderstanding.    Ornamental Stones stone is one of the world in a wonderful, beautiful colors and patterns available for viewing. She mainly from the Yangtze River, Nanjing has beautiful scenery and Liuhe. Stone in order to "spend" the name of flower and crown rain, beautiful. history and legend    Gestation to stone formation, after the formation of primary, secondary layer of gravel and sediment removal of these three stages of the complex and lengthy, but also can be experienced significant romantic side of the vicissitudes of life. Stone, is a natural flower agate, mainly produced in Luhe District, Nanjing City, Jiangsu Province, for the nation's largest stone origin. Produced by the quality of stone, shape, pattern, color, was like, six mood in both the United States, known as "heaven-sent David, the Chinese a must." Beautiful stone was appreciated, collectors have thousands of years of history, in recent years, weathering complex, the stone much at home and abroad who favor and become a gift from relatives and friends and enjoy a collection of precious gifts.    Stone unique to the United States for China's stone, in百千kinds of stones, the stone can be called the best in Queens. Referred to stone, is a head start on the stone myth: the ancient legend of the platform is a Yuhuatai Yuhuatai concept, Yuhuatai Yuhuatai concept in a real person. Yuhuatai live a dignified and wise, deep Ruoxu, he staged a sit-in rather than by the Christian and Missionary Alliance, as if their is a MacGraw玄秘by the book. One day, Yuhuatai real open altar preaching. Implication, hanging river water into the root of the matter, cough spit into beads, the charm of the character and wisdom shocked many people moved heaven and even the gods, gods command joy of colorful rainy weather to rain. Colorful rainy weather杂沓shoulder to shoulder and the next one after another, like a treasure in the National Palace Museum in the landscape scroll Mi Fu. Yuhuatai泠泠rainwater percussion on stage in a粒粒turned into a stone like agate. Chemical composition    Silica stone composition is mainly composed of red iron ions and ferrous ions. Stone is a stone for the agate, opal, chalcedony, quartz pebbles, etc., found in the riverbed, river terrace sediments, of which the most famous Nanjing Yuhuatai stone output. Stone is divided into small two types of stone and rough stone, small stones to agate mainly stone delicate, bright colors, rounding high Jingying lovely; coarse to coarse stone, quartz or metamorphic rock mainly low value . Beautiful stone often can present a variety of landscape, figures, birds, animals, trees, such as a scene of people lost in conjunction Pina, thoughts into the stone, very beautiful.    As a result of a wide range of stone, its causes and chemical composition is extremely complex. To agate gravel for example, from the original agate. Is generally believed that agate is a native of residual magmatic hydrothermal formation. Such hydrothermal filling in the volcanic rocks such as basalt, rhyolite gap as a result of the gap of different shapes, or into agate ball, or into a vein agate. After the role of the forces of nature, native agate falling out after the impact of flash floods, water handling, ground into gravel. This is what we have seen in the gravel layer Yuhuatai agate stone.    Stria stone its surprising色艳known to the world of natural beauty. It is the ring-shaped pattern around the volcanic silica glue gap cavity, the wall began, from the outside-in multi-layered sediment layers formed. In its growth process, often with color ions and compounds the cycle of proliferation. Agate raw main chemical composition is silicon dioxide, followed by a small amount of iron oxide and traces of manganese, copper, aluminum, magnesium and other elements and compounds. They themselves have different colors, such as red for iron, copper for blue, purple for manganese, yellow translucent stone for myeloid colloidal silicon dioxide, emerald green color with minerals and so on; as a result of these ions into dioxide pigment hydrothermal silicon content in different types and, thus showing a bias, changing color depth, so colorful and beautiful scenery.
