# 龟纹石



# 基本属性

龟纹石形成于在距今5.4亿~2.5亿年的寒武纪早期。地下水或者大气降水所溶解的碳酸氢钙在运移过程中，沿着质点凝聚，胶结地层中的砂粒或者黏土，最终形成了链球状、球状和不规则形状的结核石。结核石按其生成阶段可分为同生结核、成岩结核和次（后）生结核等三种。而按照其不同的物质组成则可分为硅质结核、钙质结核、锰质结核、铁质结核、硫铁矿结核等。属于同生结核和次生结核；若按物质组成则属于铁质结核。其具体的名字叫菱铁矿结核石，它的主要成分有：钙、硅、铁、锰、磷、石英、莹石等。形状多呈瘤状、透镜状、饼状或姜状。

# 产地

出产于湖南郴州市桂阳县、宜章县。在宜章的渔溪河、玉溪河、武水河、乐水河四大水系中，武水河流经的浆水乡新车坪、麻田镇泗溪村、梅田镇武水桥河段出产龟纹石。

# 分级

纹路清晰，水冲黑色、红棕色为上品，原石原皮为上品。

# 养护

纹理突出的龟纹石，使用鬃毛刷；光滑的水石，使用棉布。

不用油蜡养护；包浆后可以日晒雨淋的方式，因龟纹石含有铁矿成分，氧化后会呈现红皮。
