外表有指捏紋氣印，有一層黑色或深褐色熔殼，這是新鮮墜落隕石最典型特征。而隕石墜落后，如果長期沒被發現或沒被保護，會受到氧化、風化影響使他們的外表特征發生變化，并且不同類別的隕石，其所含礦物結構特征不同，變化也不同，所體現出的顏色也會有差異。
The surface of the pinnix airprint, a layer of black or dark brown molten shell, is the most typical features of fresh falling meteorites. After a meteorite falls, if it has not been discovered or protected for a long time, it will be affected by oxidation and weathering so that their appearance characteristics will change. Moreover, different types of meteorites contain different mineral structure characteristics and changes, and the color reflected will also be different.
一般裂紋較多的隕石，落地后接近裂紋的部分更容易風化；有些隕石落地后熔殼全部脫落，會呈現不一樣特征；有些隕石落地后鐵氧化明顯，會讓隕石呈褐黃色或褐紅色；還有些隕石所含礦物硅酸鹽占比大，如含輝石長石多，又會呈現不同顏色，等等。
Generally, meteorites with more cracks are more likely to be weathered near the cracks after landing. After some meteorites fall to the ground, all the molten shells fall off, will show different characteristics; Some meteorites fall to the ground with iron oxidation, which can make meteorites brownish yellow or maroon. Some meteorites contain a greater proportion of mineral silicates, such as pyroxene feldspar, which appears in different colors, and so on.
隕石大體可分為石質隕石、鐵質隕石、石鐵混合隕石、玻璃隕石等。傳統的隕石交易主要以金屬隕石為主，如我國廣西南丹的鐵隕石、納米比亞的鐵隕石、新疆的富康橄欖石鐵隕石等。這些隕石因知名且相對有固定的價值，受到藏友們喜愛。
Meteorites can be roughly divided into stone meteorites, ferrometeorites, stone and iron mixed meteorites, glass meteorites and so on. The traditional meteorite trade is mainly dominated by metal meteorites, such as the iron meteorite from Nandan, Guangxi, Namibia and Fukang, Xinjiang. These meteorites are popular among Tibetans because they are well known and have relatively fixed value.
如文中此這枚隕石，通體成不規矩形狀，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，無論從重量還是歷史價值和科研價值來說都是稀有的，升值潛力無限，值得收藏。
Such as the text of this meteorite, the entire body into irregular shape, the appearance of a layer of oxide coating, called molten shell; Many large and small round pits on the surface are called air prints; In addition, there are grooves of various shapes, called melting trenches, and the presence of highly visible melting lines; These are caused by the intense friction and combustion with the atmosphere as they fall. Viewed under a high magnifying glass, the ferrocene meteorite, with its distinctive crystalline grains, is rare in terms of weight, historical value and scientific value, with unlimited appreciation potential and worth collecting.
