几千元一克的石陨石来了…就是那么牛
Winonaite 辉石无球粒陨石，该类型最初发现与一次考古墓葬发掘有关，非常珍贵的类型！真正值几千一克的石陨石来了，不是土豪想动都动不了[憨笑][憨笑][憨笑]私藏品（欣赏专用）
新入手的一个重量级收藏，Winonaite (metal-veined) 辉石无球粒陨石，馆藏级，表面宽大的金属脉，此种陨石非常稀有，其基质类似于IAB铁陨石里面的硅酸盐包体，属于一种原始无球粒陨石，此块外观特征及重量均为馆藏级别，目前属个人收藏品。真正价值几千元一克的石陨石来了……就它了。
Silicate-rich regions of the specimen have a metamorphic, triple grain junction texture (mean grainsize ~150 µm) and are composed of olivine, orthopyroxene, sodic plagioclase, kamacite, taenite and troilite. Cross-cutting metal-rich veins and patches are composed predominantly of kamacite and taenite.
Olivine (Fa1.1-1.3, FeO/MnO = 3-5, N = 5), orthopyroxene (Fs6.5-6.9Wo1.8-2.1, FeO/MnO = 9-10, N = 4), plagioclase (An14.8-15.4Or3.1-3.4, N = 2). Oxygen isotopes ：analyses of acid-washed subsamples by laser fluorination gave, respectively, δ17O 1.969, 2.049, 2.119; δ18O 4.730, 4.887, 5.035; Δ17O -0.528, -0.531, -0.540 per mil.
