石中瑰宝：精选推荐

木化石是最少上亿年的树木，因火山喷发或地壳运动等地质作用，而被迅速埋葬地下后，由于处于缺水的干旱环境或与空气隔绝，木质部分被地下水中的二氧化硅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，又称硅化木或树化玉。

藏品介绍

中文名称：木化石

英文名称：Petrified wood

类别：杂项

规格：两块

上图树化木木质纹理清晰，质地坚硬便于收藏，说到硅化木从古生代石炭纪开始（始于距今3.55亿年）到白垩纪中期（结束于距今1.25亿年）之间均有分布。硅化木主要生成的年代是中生代时期，以侏罗纪、白垩纪中期年代的居多。到21世纪为止最早的木化石是石炭纪早期的裸蕨植物化石，最新的为1.035亿年前白垩纪晚期的硅化木。

此件天然木化石，树干原生微细结构保存完好，质地细腻坚硬，色泽丰富又有清晰的纹路，能反映出树木种类、树皮、树枝、肌理等信息，观赏时会产生视觉、审美、感性和悟性方面的共鸣。其观相古拙典雅，刚直有力。一直以来，人们都将木化石用作皇家宫苑、园林建筑、厅堂雅室的装饰，在案头书桌中也广为应用。

硅化木不但可以以其材质展示富贵和美丽，还可以凭借其化石的年轮、树皮、节瘤、虫洞、肌理等斑斓多姿的特征记录和见证亿万年的地质变迁和物种衍化，为人们研究古植物、古生物史、古代地质和气候变化提供线索。

一般形成木化石都是具有抗腐蚀性的木材，有一定的杀菌能力，普通的木材经过上亿年早已经碳化形成煤炭甚至石油。

木化石是地质学所称硅化木中的极品，它深埋于地下，是天下稀有的亿万年前遗世孤品。木化石集天地之灵气，纳日月之精华，它是集木、石、玉为一体的宝石佳品。本身木化石就非常稀少，且年代悠久，因此此件木化石，具有极高的科研价值和保藏价值。

陨石是起源于外太空，撞击到地球表面后残存的天然物体。当它还在陨石太空时称为流星体，当他进入大气层时，撞击压力使这个物体被加热和放射出光线，于是成为火球，即所谓的流星。火球这个名词显示这是来自地球之外并与地球碰撞的一个物体，或是极端明亮，类似火球这样的流星最终将撞击到地球的表面。

更通俗的说，陨石是来自太空中任何地方，落在表面上的自然天体。月球和火星上也发现到了陨石。陨石因为撞击或经过大气层时发光成为流星时被观测到而被寻获的称为墬落陨石，所有其它的陨石都称为发现陨石。陨石是石头，也是星星。

上图这块陨石，表面融壳极为明显，与地球撞击后地球的沙土已经与陨石融为一体，懂行的人一看便知是陨石无疑。

新疆乌鲁木齐惊现8千万天价陨石，整个体形只有拳头般大小。据介绍，该陨石已经至少46亿岁了，和地球差不多同龄。而之所以能够标8千万天价，其理由是因为当时坠落时，有人目击全程。

不管是不是炒作，陨石的价值毋庸置疑，他是我们研究太空文明最有力的标本，而陨石泡茶可以调节人体磁场使人倍感精神，企业家也花重金请陨石寓意‘时来运转’目前陨石对很多人来说非常神秘，一些科幻大片也有陨石降落赋予有缘人超能力的情节，可见其神秘程度。

这三件藏品两件时间跨度极大，来自亿年以前，一个空间跨度极大，来自外太空，是最好不过的收藏组合。物以稀为贵，千金易得一宝难求。

英文翻译：Fossil wood is at least hundreds of millions of years of trees, due to volcanic eruptions or crustal movement and other geological processes, and was quickly buried underground, due to the lack of water in the dry environment or isolated from the air, wood part of the exchange of silica in groundwater into the fossilized trees. It preserves the wood structure and texture of the tree. Color for earth yellow, light yellow, yellow brown, red brown, gray, gray, black, polishing surface can have glass luster, opaque or slightly transparent, because part of the texture of wood fossils appear jade texture, also known as silicified wood or tree jade.

The collection is introduced

Chinese name: fossil wood

English name: Petrified wood

Category: miscellaneous

Specification: two pieces

The woody wood in the above image has a clear texture and a hard texture that is easy to collect. It is said that silicified wood was distributed from the beginning of the carboniferous period (355 million years ago) to the middle cretaceous period (125 million years ago). Silicified wood was mainly produced in the Mesozoic era, with the Jurassic and the middle cretaceous. The earliest fossilized wood to date in the 21st century is the early carboniferous fern fossil, the latest is 103.5 million years ago late cretaceous silicified wood.

This piece of natural fossil wood, the trunk of the original fine structure is well preserved, the texture is fine and hard, rich color and clear lines, can reflect the tree species, bark, branches, texture and other information, visual, aesthetic, perceptual and understanding resonance. Its view is ancient and elegant, straight and powerful. Since all the time, people use wood fossil as the adornment of royal palace, garden building, hall hall elegant room, also be widely used in desk.

Silicified wood can not only display wealth and beauty with its material, but also record and witness the geological changes and species evolution of hundreds of millions of years by virtue of its colorful characteristics of fossil rings, bark, nodules, wormholes, and texture, providing clues for people to study ancient plants, paleontology, ancient geology and climate change.

Generally speaking, fossilized wood is wood resistant to corrosion and has certain bactericidal capacity. Common wood has been carbonized to form coal and even oil after hundreds of millions of years.

The fossil wood is the best in the silicified wood called by the geology, it is buried deep in the ground, is the world rare hundreds of millions of years ago. Wood fossils set heaven and earth aura, the essence of the sun and the moon, it is set wood, stone, jade as one of the gem. The wood fossil itself is very rare, and the age is long, therefore this wood fossil, has the extremely high scientific research value and the preservation value.

Meteorites are natural remnants of objects that originated in outer space and hit the earth's surface. When it was in meteorite space, it was called a meteoroid. As it entered the atmosphere, the impact pressure caused the object to heat up and emit light, resulting in a fireball, called a meteor. The term fireball indicates that it is an object from outside the earth that is colliding with the earth, or that an extremely bright meteor, such as a fireball, will eventually hit the earth's surface.

More commonly, meteorites are natural objects that fall on the surface from anywhere in space. Meteorites have also been found on the moon and Mars. Meteorites found when they were observed as meteors when they struck or passed through the atmosphere, are called falling meteorites. All other meteorites are called discovery meteorites. Meteorites are stones and stars.

The collection is introduced

Chinese name: meteorite

English name: meteorites

Category: miscellaneous

Specification: one piece

This meteorite, pictured above, has a clear melting shell, and the earth's sand has been fused with the meteorite after the impact.

Urumqi, xinjiang, 80 million sky high meteorite, the entire body is only the size of a fist. The meteorite is said to be at least 4.6 billion years old, about the same age as earth. The reason it was able to bid million was because someone had seen the whole thing at the time of the fall.

Whether the hype, the value of meteorites, no doubt, he is the most powerful specimens, we study space civilization and meteorites make tea can make people feel more spirit of adjusting human body's magnetic field, entrepreneurs also spent heavily on moral please meteorites' fortunes meteorites for many people these days are very mysterious, some of the science-fiction film also has a meteorite landing is predestined friends the human ability of the plot, visible degree of its mystery.

The three pieces, two from hundreds of millions of years ago, and one from outer space, are the best combination. A rare thing is more valuable than a precious thing.
