木化石 - 化石木材 - 38 cm - 28 cm

来自马达加斯加的极为保存完好的化石木片。地质时期：下侏罗纪。色彩美丽，木材纹理清晰且保存完好，质量确实卓越。
Note the beautiful mineral crystallization created over millions of years inside the cracks of the wood
这是来自马达加斯加阿姆比洛贝（Ambilobe）的广圆形化石木（Araucaria 属的一员，属于包括现代 Monkey Puzzle Tree 的科）。这块约2.2亿年前的化石木已被两面切片并打磨，便于清晰看到内部木纹细节和美丽的颜色。
Petrified wood is the name given to wood that has been turned into stone (fossilized) through the process of permineralization. In this process, all of the organic matter becomes replaced by minerals, while much of the original structure, such as tree rings, is retained. For this to happen, the wood needs to be buried in an environment low in oxygen to prevent decomposition and with flowing, mineral-laden water, so minerals may replace structures. The coloration is caused by various minerals/impurities present in the water during fossilization. For example, red colors in many cases can be attributed to iron compounds, greens due to copper, and so on
化石木指通过矿化作用将木材转变为石头（化石化）的木材。在这个过程中，所有有机物被矿物质取代，同时保留了原始结构的大部分，如树轮。要发生这种现象，木材需要埋在缺氧的环境中以防止分解，并且有流动、富含矿物质的水，以便矿物质能够替代结构。着色由化石化过程中水中的各种矿物/杂质引起。例如，红色在很多情况下可归因于铁化合物，绿色来自铜，等等
