产自广西红水河,其原岩是致密块状的砂岩,成岩后受火山喷发作用影响,经接触变质,块体较大,石体没有存留层理面,而岩石中的成分、结构又有一定的差异,局部也有一些不穿透石体的节理,这些部位受河流水蚀及冲刷而被蚀去,留下没有裂隙的坚硬块体,又因为其所处河床环境的特殊,使一般很难保存下来的弧形弯曲部位保存完好,从而形成十分奇特的外形。摩尔石形态特别,无层次结构,条线柔和、流畅、完整、抽象,富有独特的神韵;坚硬致密,石肤细腻;主要以青灰色调为主、也有的微带黄色,以纯黑 Produced from the Hongshui River in Guangxi, the original rock is a dense block of sandstone, after diagenesis affected by volcanic eruptions, by contact metamorphism, the larger block, the stone does not exist bedding plane, and rock composition, structure and There are some differences, some also have some non-penetrating stone joints, these parts of the river by water erosion and erosion was eaten away, leaving no hard rock block, and because of its special riverbed environment, so that is generally very Difficult to save curved arcs well preserved, resulting in a very strange shape. Mohr stone special shape, no hierarchy, soft lines, smooth, complete, abstract, full of unique charm; hard and dense, delicate skin; mainly gray-gray tone, and some microstrip yellow to pure black
