自然石鐵隕石
隕石(meteorite)也稱“隕星”,是地球以外脫離原有運行軌道的宇宙流星或塵碎塊飛快散落到地球或其它行星表面的未燃盡的石質、鐵質或是石鐵混合的物質。大多數隕石來自于火星和木星間的小行星帶,小部分來自月球和火星。隕石大體可分為石質隕石、鐵質隕石,石鐵混合隕石。
Meteorite, also known as "the comet", is an unburned stone, iron or stone-iron mixture that is scattered from the surface of the Earth's orbiting or other debris. . Most of the meteorites come from the asteroid belt between Mars and Jupiter, and a small part comes from the moon and Mars. Vermiculite can be roughly divided into stone vermiculite, iron vermiculite, and stone iron mixed vermiculite.
隕石被定義為是地球以外脫離原有運行軌道的宇宙流星或塵碎塊飛快散落到地球或其它行星表面的未燃盡的石質的、鐵質的或是石鐵混合物質,亦稱“隕星”。根據其內部的鐵鎳金屬含量高低通常分為三大類:石隕石、鐵隕石、石鐵隕石。絕大多數隕石來自位于火星和木星之間的小行星。它們含有地球上不常見的礦物組合,或者地球上沒有的球粒結構,通過研究隕石可以獲得對太陽系的物質起源、組成和演化的認識。石鐵隕石Stony-iron Meteorite,是隕石的一種。這類隕石中硅酸鹽與鎳鐵合金的含量各占50%。石鐵隕石又分為橄欖隕石與中鐵隕石兩個子類。是比較罕見的一類隕石,占隕石數量的2%～4%,鐵鎳和硅酸鹽礦物含量相當(30%～65%)。主要礦物有橄欖石、各種輝石、鐵紋石和鎳紋石。
Meteorites are defined as unburned stone, iron, or stone-iron mixtures of cosmic meteors or dust fragments from the original orbit outside the earth that quickly disperse onto the surface of the earth or other planets. ". According to the internal iron-nickel metal content, it is usually divided into three categories: stone meteorite, iron meteorite, stone iron meteorite. Most meteorites come from asteroids between Mars and Jupiter. They contain mineral combinations that are not common on the earth, or spherulite structures that do not exist on the earth. Through the study of meteorites, we can obtain an understanding of the material origin, composition and
evolution of the solar system. Stone iron meteorite Stony-iron Meteorite is a type of meteorite. These meteorites each contain 50% of silicates and nickel-iron alloys. Stone iron meteorite is divided into two subclasses of olive meteorite and medium iron meteorite. Is a relatively rare type of meteorite, accounting for 2% to 4% of the number of meteorites, iron nickel and silicate mineral content (30% to 65%). The main minerals are olivine, a variety of pyroxene, iron-grain, and nickel-grain.
石鐵隕石外表裹著一層氧化層,叫熔殼;表面分布的許多大大小小的圓坑,叫做氣印;此外還有形狀各異的溝槽,叫做熔溝,并存在十分醒目的熔流線;這些都是由于它們隕落過程中與大氣劇烈摩擦燃燒而形成的。在高倍放大鏡下觀察該石鐵隕石,有明顯的晶狀顆粒。石鐵隕石包含著大量豐富的太陽系天體形成演化的信息,對它們的實驗分析將有助于探求太陽系的奧秘。通過對隕石中各種元素的同位素含量測定,可以推算出隕石的年齡,從而研究太陽系開始形成時期的各種信息。此外石鐵隕石還能攜帶來小行星、行星、大的衛星或彗星等這些天體的原始信息,所以十分具有科研價值。
The surface of the stone iron meteorite is wrapped with an oxide layer, called a molten shell; many large and small round pits distributed on the surface are called air marks; in addition, there are grooves of various shapes, called melting grooves, and there is a very striking melt. Streamlines; these are formed by their intense friction and combustion with the atmosphere during their fall. Observing the stone iron meteorite under a high magnification, there are obvious crystalline particles. Stone iron meteorite contains a wealth of information about the formation and evolution of solar system objects. Experimental analysis of them will help to explore the mysteries of the solar system. By measuring the isotopic content of various elements in the meteorite, the age of the meteorite can be deduced to study various information about the period when the solar system began to form. In addition, the stone-iron meteorite can carry the original information of asteroids, planets, large satellites, or comets, so it is of great scientific value.
此組自然石鐵隕石是趙先生收藏的珍品,4枚石鐵隕石,此石鐵隕石通體似鐵非鐵,似石非石,其色渾然天成,獨具特色;整體硫燒痕跡清晰可見。外表裹著一層黑色的的氧化層,叫熔殼;表面分布的許多大大小小的熔坑,叫做氣印;這些都是由于它們隕落過程中與大氣劇烈摩擦燃燒而形成的。它不僅具有一般高端收藏品的稀有性,其科學探索的價值是隕石獨有的內涵,正是這種內涵決定了隕石收藏具有深刻的內在價值發現和無窮的魅力。從長遠看來,遠非一般收藏品所能比擬。
