火山喷发，地质学专业术语，是一种奇特的地质现象，是地壳运动的一种表现形式，也是地球内部热能在地表的一种最强烈的显示。是岩浆等喷出物在短时间内从火山口向地表的释放。由于岩浆中含大量挥发分，加之上覆岩层的围压，使这些挥发分溶解在岩浆中无法溢出，当岩浆上升靠近地表时，压力减小，挥发分急剧被释放出来，于是形成火山喷发。火山喷发石往往都爆发出巨大的能量和伴随着极高的毁灭性，几乎可以说是火山喷发之处将“尸横遍野，寸草不生”！而由于火山岩的温度极高，很多生物体和无生命物质在被其淹没时就融化了，因此能够保存下来的火山化石极其稀少，加之火山化石对我们研究过往的地质文化和人文条件有着极其重要的作用，所以预防显得火山化石弥足珍贵！

Volcanic eruption, geology term, it is a kind of peculiar geology phenomenon, crustal movement is a form, is also the interior of the earth thermal energy is one of the most intense display on the surface. Such as magma ejecta in a short period of time to the release of the earth's surface from the crater of the volcano. Due to magma contains a large number of volatile, and confining pressure of overburden, make these volatile dissolved in the magma cannot overflow, when rising magma near the surface, the pressure decreases, and volatile sharply was released, so the formation of volcanic eruptions. Volcanic eruptions tend to burst into a huge amount of energy and with extremely high devastating, almost is the place of volcanic eruptions will "corpses, nothing grows"! Due to the high temperature of volcanic rock, a lot of living organisms and nonliving matter when submerged by the melting, can therefore preserved fossils are rare, and volcanic fossil for us to study of geological culture and cultural conditions has a very important role, so prevention is volcanic fossil precious!

普遍化石一般是平行沉积，多为片状结构，岩石硬度偏小，没有色泽；而火山化石的沉集相对杂乱，岩石硬度大线条扭曲厉害，多为块状结构，色泽相对丰富，这样从它们状态中可以解读出这些来自地球深处的众多地理信息。通过对它们的所含元素成分检测，我们就知道这里火山岩浆中各种物质含量；火山的结构类型；这些物质成分对当时环境和生态影响范围等等信息。因此，火山化石具有极高的科研价值和鉴赏价值，这也使得火山化石成为众多科研人员和收藏爱好者的心头好，具有很高的升值空间。

Fossils are generally parallel deposition, common to the lamellar structure, rock hardness is small, no color; And volcanic fossil heavy set relatively mixed and disorderly, rock hardness big line distortion, more for massive texture, colour and lustre is relatively abundant, so from their state can be read out these numerous geographic information from deep inside the earth. By their composition elements in testing, we know here various substances content in the volcanic magma; The type of volcanic structure; The material composition of environmental and ecological impact range, etc. Therefore, volcanic fossil has high research value and appreciation value, it also makes volcanic fossil collector of numerous scientific research personnel and good heart, has the very high appreciation of space.

文中图示火山化石重量约2815g，保存完整，外形圆润，凹凸的石头纹路，完美复原了当时被炙烤焚烧时产生的纹理和岩浆脉络。整体看上去，光泽润丽明亮，色泽褐黑发亮，端庄厚重，浑然天成。没有微孔，质地坚硬，凹凸有致，筋骨毕现，千姿百态，栩栩如生极具观赏性和艺术性！据史料记载。中国最早记录的活火山是山西大同聚乐堡的昊天寺，它在北魏(公元 5世纪)时还在喷发；东北的五大莲池火山在1719年至1721年，还猛烈喷发过，其情景是：“烟火冲天，其声如雷，昼夜不绝，声闻五六十里，其飞出者皆黑石硫磺之类，经年不断…… 热气逼人30余里”。可见火山爆发由来已久，可是能够保存下来的火山化石确极其稀少，这更加鉴定了火山化石的尊贵地位和收藏价值！

The graphic volcanic fossil weight about 2815 g, intact, appearance is fruity, the stone grain of concave and convex, perfectly healed his was burned when the texture and magma veins. The overall look, ZeRun beautiful bright light, colour and lustre is brown glossy black, dignified and thick, like nature itself. No pores, hard, concave and convex have send, bones and muscles scene, various, vivid highly ornamental and artistic! According to historical records. China is the earliest record of active volcanoes in shanxi datong together heaven temple, science of le fort it return when the northern wei dynasty (5th century AD) in the eruption; Northeast of the five lianchi volcano in 1719 to 1721, had a violent eruption, the situation is: "the fireworks going up into the sky, day and night the sound of thunder,, their five or six miles, its fly out all black stone such as sulfur, years continuously... "In the hot gas is threatening more than 30. Has long been a volcanic eruption, but can be preserved in the fossil is extremely rare, the more exalted status and appraise the volcano fossil collection value!

在火山化石的发现史上最让人感动的应该就是紧紧相拥了两千多年的一对庞贝情侣。在死亡来临之前，高大的那个男子即使知道这样做毫无用处确仍然把自己女友的头紧紧的护在胸口，最后相拥死去的画面定格了千年，让千年后的我们再去见证他们的刻骨铭心的爱情与至死不渝的守候，让人不得不感慨火山活石真的就是一本不会言语的故事书，值得我们去揣摩珍藏。

The discovery of fossil in the history of the volcano are embracing the most moving should be the Pompeii couple of more than two thousand years. Just days before the arrival of death, even knowing the man on the tall do useless is still tight in the chest, his girlfriend head finally embrace dead picture frames for one thousand years, one thousand years later we'll witness their deep-rooted of love and loyalty of waiting, let a person have to sigh with emotion volcanic living stones is really a book won't words story, is worth us to ponder the collection.
