栖真石产于安徽黄山东麓的旌德县栖真山。此山延绵数十里。据华东地区区域地层表介绍,其中有些地层为距今约6-5亿年浅海相沉积的硅质和石灰质相迭层建造。由于燕山时期黄山地区的造山运动使处在黄山周围的地表也相对隆起为丘陵。炽热的地下岩浆又使得周边地区的沉积岩热变成变质岩。栖真山脉的一个小支脉变质岩出露地表。千百万年的水蚀风化作用,洗刷了其中部分松软灰岩,留下了表层坚硬的硅质岩;由于出露带正好处在人迹罕至的莽山管谷,荆棘丛生,斑茅密布,使得其石表面基本上保持了自然状态。小块石体有的埋埋于碎石泥土里,有的散落在母体裂罅中。石体表面上粗细不等的棱角如芒,沟纹深邃,无人为破坏痕迹。还有的经水冲下山后被先民们就地垒砌在溪墈塘坝中,遇有山洪暴发,墈坝倒塌,则偶可觅得千疮百孔者。栖真石佳者叠褶细密,紧劲联绵,最薄处仅1-2毫米就是一层褶皱,高高低低,重重叠叠。这就为能
Habitat stone produced in east Huangshan Anhui Jingde County habitat Hill. This mountain stretches tens of miles. According to the description of the regional stratigraphic tables in East China, some of these strata are siliceous and calcareous laminations deposited from about 500 million to 500 million years ago. Due to the orogeny in Huangshan area of Yanshan period, the surface around Huangshan is also relatively uplifted to the hills. The hot underground magma in turn makes the surrounding area of the sedimentary rocks become metamorphic rocks. A small veins of the Qizhen Mountains expose the surface of the earth. Water erosion weathering millions of years, scrub some of which loose limestone, leaving the hard surface of the chert; due to the outcrop just inaccessible Mangshan tube valley, thorns tufts, plaques, making its Stone surface basically maintained its natural state. Some small stones buried in the gravel soil, and some scattered in the maternal fissure. Stone body surface ranging from thick edges such as Mount, deep groove, no one to damage traces. There are also rushed down by the water after the ancestors were built on the site in the stream pond dam, in case of flash floods, dam collapse, you can even find riddled people. Very good habitat real rock fold plentiful, tightly linked, the thinnest Department only 1-2 mm is a layer of folds, high and low low, heavy stacked. This is possible
