陨铁,石铁陨石iron meteorite,主要成份为的陨石。

主要由铁纹石和镍纹石两种矿物组成,其次含有少量的石墨、陨磷铁镍矿、陨硫铬矿陨碳铁铬铁矿陨硫铁等。在化学成分上除Ni和Fe外,还含有Co、S、P、Cu、Cr、Ga、Ge和Ir等元素。有少数铁陨石还含有硅酸盐包体。铁陨石的分类主要根据Ni、Ga、Ge和Ir的含量及其构造特征,分为13个群。

Iron meteorite is mainly composed of iron and nickel.

It is mainly composed of two kinds of minerals, i.e. serpentine and nivalite, followed by a small amount of graphite, chondrite, pyrochromite, chromite and pyrite. Besides Ni and Fe, it also contains Co, s, P, Cu, Cr, GA, GE and IR. A few iron meteorites also contain silicate inclusions. According to the contents of Ni, GA, GE and IR and their tectonic characteristics, the iron meteorites can be divided into 13 groups.

石铁陨石似乎像一块巨大的烧灼物体,表面布满了角形腔结构,科学家认为这可能是岩石边缘的金属晶体受到侵蚀后形成的,另一种可能的解释是这些中空的腔形结构与橄榄石具体有关,这种物质可以在罕见的石陨石中发现,而后者形成的过程比较复杂,一般情况下科学家认为其形成于行星核幔附近的边界层上,显然石陨石是一种比较罕见的物质。

The iron meteorite seems to be like a huge burning object, and its surface is covered with angular cavity structures. Scientists think that this may be formed after the metal crystals at the edge of the rock are eroded. Another possible explanation is that these hollow cavity structures are specifically related to olivine, which can be found in rare meteorites, and the formation process of the latter is more complex, In general, scientists believe that it was formed in the boundary layer near the planet's core mantle. Obviously, meteorite is a relatively rare material.

石铁陨石有两种分类法被使用,较早的结构分类法是以百分比或是魏德曼花纹为依据,可以从用酸蚀刻后,在抛光的表面上呈现的交叉条纹来评估。这种分类与铁镍的相对丰度相联结,分类为:六面体陨铁:低镍含量,没有魏德曼花纹。八面体陨铁:通常镍含量较高,有魏德曼花纹,最为普通。

无纹陨铁:镍含量很高,没有魏德曼花纹,非常罕见。

八面体陨铁可以依据魏德曼花纹的特性再进一步分为粗糙、中等、和细致的八面体陨铁。

Two classifications of iron meteorites have been used. The earlier structural classifications are based on percentages or weidmann patterns, which can be evaluated by the cross stripes on polished surfaces after acid etching. This classification is associated with the relative abundance of iron and nickel, which can be classified as hexahedral meteorite iron with low nickel content and no weidmann pattern. Octahedral meteorite: usually high nickel content, weidmann pattern, the most common.Matte meteorite: high nickel content, no weidmann pattern, very rare.Octahedral meteorites can be further divided into coarse, medium and fine octahedral meteorites according to the characteristics of weidmann pattern.
