化石拍賣

一块来自马达加斯加、保存极为完好的化石木片。地质时期为下侏罗世。颜色美丽，木纹清晰且保存完好，质量极佳。
请注意，经过数百万年在木缝中形成的美丽矿物晶体。
这是来自马达加斯加安比洛贝（Ambilobe）的一块宽圆形木化石（Araucaria）。Araucaria 是针叶树科的一员，包含现代猴谜树（Monkey Puzzle Tree）。这块约2.2亿年前的木化石已被两面切片并打磨，可以清晰看到内部木纹细节和美丽的着色。
木化石是通过矿化作用将木材变成石头的过程。在这一过程中，所有有机物质被矿物质取代，而原有的结构，如树轮，仍被保留。要使此过程发生，木材需要埋藏在缺氧环境中以防止分解，并有流动的、富含矿物质的水，以便矿物质替代结构。着色来自化石化过程中水中存在的各种矿物质/杂质。例如，红色在许多情况下可归因于铁化合物，绿色则归因于铜，等等

A really well preserved fossil wood slice from Madagascar. Period Lower Jurassic. Beautiful colors, evident and beautifully preserved wood texture, truly excellent quality. 
Note the beautiful mineral crystallization created over millions of years inside the cracks of the wood
This is a wide round of petrified wood (Araucaria) from Ambilobe, Madagascar. Araucaria is a coniferous tree in the family that includes the modern Monkey Puzzle tree. This 220 million year old petrified wood has been sliced and polished on both sides, allowing the stunning inner wood detail and beautiful coloration to easily be seen.
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
