今天为广大藏友带来的是来自一位资深收藏家陆先生的珍藏“树化石”。下面，为大家介绍一下这件藏品：

Today, for the vast number of Tibetan friends brought is from a senior collector Mr. Lu's collection of "tree fossils". Next, I would like to introduce this collection to you.

 

树化石是最少上亿年的树木被迅速埋葬地下后，木质部分被地下水中的SiO₂交换而成的树木化石。它保留了树木的木质结构和纹理。颜色为土黄、淡黄、黄褐、红褐、灰白、灰黑等，抛光面可具玻璃光泽，不透明或微透明，因部分木化石的质地呈现玉石质感，树化石或树化玉。硅化木是上亿年前的树木因种种原因被埋入地下，在地层中，树干周围的化学物质如二氧化硅、硫化铁、碳酸钙等在地下水的作用下进入到树木内部，替换了原来的木质成分，保留了树木的形态，经过石化作用形成的植物化石，因其中所含的二氧化硅成分多，所以，常常称为硅化木或树化玉。

Tree fossils are tree fossils that are exchanged by SiO Ramming in groundwater after at least hundreds of millions of years of trees are buried underground rapidly. It retains the wood structure and texture of trees. The color is yellowish, light yellow, yellowish brown, reddish brown, gray-white, grey-black and so on. The polished surface can be glassy, opaque or slightly transparent. Because some wood fossils have a jade texture, tree fossils or tree fossils. Silicated wood was buried underground for a variety of reasons hundreds of millions of years ago. In the stratum, chemical substances such as silicon dioxide, iron sulfide and calcium carbonate around the trunk entered the interior of the tree under the action of groundwater, replaced the original lignin composition, retained the shape of the tree, and fossil plants formed through petrochemical process. Because there are many silicon dioxide components in it, it is often called silicified wood or dendritic jade.

 

古代树木因火山喷发或地壳运动等地质作用而被埋入地下，由于处于缺水的干旱环境与空气隔绝，木质不易腐烂，在漫长的地质作用过程中被含硅钙物质交换替代，替换的过程保存了木质的纤维结构和树干的外形，使树木变成化石

树木保存为化石的条件极为苛刻，树干要想成为硅化木，先决条件是其树干必须得到迅速掩埋，环境的特殊，与空气隔绝这种迅速掩埋的情况毕竟是极少见的，因此，树木成为化石的几率非常小。

树木被泥沙埋藏后，含丰富硅质成分的地下水溶液一边溶解树木的木质成分，一边将自己携带的硅质成分沉淀于所溶解的孔洞中，发生物质交换替代现象。如果溶解和交替速度相等，且以分子相交换，则可保存树木的微细结构，如年轮及细胞轮廓等。如交替速度小于溶解速度，则主要保存了树木的形态，年轮一般不清楚。

最后，树木的原来成分已荡然无存，全部由含硅钙成分的石质所取代。之后，经过压实、固结、成岩，原来的树木就完全变成了坚硬的石头木化石。

Ancient trees were buried underground because of volcanic eruption or crustal movement. Because they were isolated from the air in the arid environment of water shortage, the wood was not easy to decay. During the long geological process, they were replaced by the exchange of silica-calcium-containing materials. The process of replacement preserved the fibre structure of wood and the shape of tree trunk, making the trees become. Fossil

The conditions for trees to be preserved as fossils are extremely harsh. The prerequisite for trees to become silicified wood is that their trunks must be buried quickly. After all, the situation of rapid burial is very rare because of the special environment and the isolation from the air. Therefore, the probability of trees becoming fossils is very small.

After the trees are buried by sediment, the underground water solution containing abundant siliceous components dissolves the wood components of the trees while depositing the siliceous components carried by the trees in the dissolved holes, which results in the substitution of material exchange. If the dissolution and alternation rates are equal and the molecules are exchanged, the fine structures of trees, such as rings and cell contours, can be preserved. If the alternating rate is less than the dissolution rate, the tree morphology is mainly preserved, and the ring is generally not clear.

Finally, the original composition of trees has disappeared, and all of them have been replaced by stone containing calcium and silicon. After compaction, consolidation and diagenesis, the original trees were completely turned into hard stone wood fossils.

 

优质木化石兼有化石之美、奇石之美和玉石之美，除了可制作化石摆件、奇石摆件和玉石摆件外，还可以经过切割和琢磨以制作硅化木珠宝首饰，如串珠、戒指、挂件、手镯等以质地细腻匀称、能反映有木质纹理或者细胞结构的为最好，而佩带这样的首饰，可以感悟地球上经历了亿万斯年的生命历程，从而增进了解地球奥秘的灵感和信心;用它制作的每一个摆件都反映了亿万年的地球生命和大千世界的无限美丽，因此对于收藏家来说是件件有故事。 High-quality wood fossils have the beauty of fossils, exotic stones and jade. Besides making fossil ornaments, exotic stones and jade ornaments, they can also be cut and polished to make silicified wood jewelry, such as beads, rings, pendants, bracelets, etc. with exquisite and symmetrical texture, reflecting wood texture or cell structure. The best is to wear jewelry like this, which can help us to appreciate the life course of the earth which has gone through billions of years, thus enhancing our inspiration and confidence to understand the mystery of the earth. Every ornament made with it reflects the infinite beauty of the life of the earth and the world for billions of years, so it is a story for collectors.

木化石的价值，可根据适用于观赏石评价的"质(品质)、色(颜色)、形(形状)、纹(花纹)、体(整体造型)"五项价值指标来鉴赏和评价。一般认为，最有价值的应该是带虫化石的木化石，其次是树枝形、树节形、数瘤形的木化石。自然，能反映出树木种类、树皮、树枝、树节、树瘤、年轮、虫洞、肌理和材质种水的，并能对收藏者个人产生视觉、审美、感性和悟性方面共鸣的木化石，就是最好的木化石。 The value of wood fossils can be appreciated and evaluated according to the five value indexes of "quality", "color", "shape", "pattern" and "body" which are suitable for the evaluation of ornamental stones. It is generally believed that the most valuable fossils should be wood fossils with insects, followed by wood fossils with branches, knots and tumors. Naturally, the best wood fossils are those that can reflect tree species, bark, branches, knots, tree tumors, rings, wormholes, texture and materials to grow water, and can resonate with collectors in visual, aesthetic, perceptual and perceptual aspects.
