About 10 kilometers southeast of Xuzhou Xincheng District, there are mountains and hills in an area north of the old Yellow River. There are many peaks, many lakes and diverse vegetation. This is the famous Xuzhou Luliang Scenic Area. There are 173 large and small hills in the area, covering an area of about 186 square kilometers. Relying on green mountains, clear water, strange stones, ancient towns and rich animal and plant resources, Xuzhou will build the Xuzhou Garden Expo Park here in 2021. The mountain slopes here are rich in a wonderful Lvliang stone, which is a unique ornamental stone in our province. It is thick, vigorous, majestic and soft in color, and is highly sought after by collectors of strange stones at home and abroad.
Some people may think that Xuzhou Lu Liang is unknown. But I don't know that this is the place where the ancient Sishui flows through, and the location of Lu State and Lu County in the Western Zhou Dynasty, the Spring and Autumn and Warring States Periods, and the Western Han Dynasty. There are Lvliangji and Lvliang Village in the local area, and Lvliang Township was once established in Tongshan County. Li Daoyuan of the Northern Wei Dynasty wrote in the "Notes on the Classic of Water", "...crossing the northeast of Pengcheng County...and southeast of the south of Lu County...There is a stone beam above the Si River, so it is called Luliang", "Three thousand meters of hanging water, Ninety miles of foam." Controlled by the fault zone of the old Yellow River, the ancient Si River has been turbulent in the area of Lvliang for thousands of years. Confucius made a special trip here to watch Lvlianghong, leaving behind the eternal famous saying that "the dead are like husbands, they don't give up day and night". Su Dongpo and Wen Tianxiang also left footprints and poems here. The ancient Sishui washed away the sediment accumulated for millions of years, and at the same time lifted the mysterious veil of Luliangshi.
According to the "Guide to Ornamental Stones in China (Jiangsu Province)", Lvliang Stone is named after the original Lvliang Township and Lvlianghong in Tongshan District, Xuzhou City, and is an outstanding representative of modeling stones among ornamental stones in my country. The Lvliang Shiyuan rock is a soluble carbonate rock deposited in the early Neoproterozoic shallow sea, with a geological age of 800 million to 1 billion years. Output, the original sedimentary strata have undergone multiple periods of crustal movement and various geological actions after formation, resulting in folds, deformations, fractures, differentiation, and uplift to the near surface, mainly formed by the dissolution of surface water and groundwater.
The limestone layer is composed of relatively pure calcium carbonate (the mineral component is calcite), which is easily corroded by water and forms many holes; the marl layer contains a certain muddy composition, which is difficult to dissolve, so there are fewer holes formed. This difference in lithology results in the difference in the degree of dissolution, thus forming the combined shape of Lvliang stone like grottoes, pavilions, reef islands and other special forms. They are thick in shape, ancient and strange, with both the edges and corners of mountains and rocks and the roundness of water stones, with a combination of rigidity and softness.
After deposition, the Lvliang Shiyuan rock formation in some parts underwent metamorphism due to magma intrusion, the limestone was marbleized and serpentinized, the mineral crystal particles became larger, and the color of the rock became more lustrous and bright; The components are fully oxidized, showing a purple-red, maroon color. The Lvliang stone formed by the rocks in these parts is more smooth and colorful, which is what people call "Jade Lvliang Stone". When the serpentine content is high, the stone body is green, and the base material composition is equivalent to "Lantian jade", so it can be carved into various shapes and carvings, which is loved by people.
The vicissitudes of life have shaped Canggu shape, the accumulation of sun, moon and stars shows simplicity and brilliance, and the beautiful Lvliang stone quietly sings in the long river of history.
