賣家描述
Northwest Africa 14688 (NWA 14688)
Purchased: 2021 Nov
Classification: Ordinary chondrite (LL5)
History: 据所有者称，这些石头由撒哈拉维陨石猎人小组于2021年10月在马里塔奥登尼以西北约100公里处发现。
Petrography: (K. Metzler, IfP) Brecciated ordinary chondrite, consisting of dark mm- to cm-sized chondritic clasts, embedded in a yellowish matrix of fine-grained related debris. The clasts show a recrystallized texture with barely visible chondrules of various textural types. Secondary feldspar grains are mostly µm. Accessory phases are Fe-Ni metal (mostly terrestrially altered) and troilite, mostly residing outside of chondrules.
Classification: LL chondrite based on mineral chemistry. Petrologic type 5, based on the equilibrated state of olivine and pyroxene and grain size of secondary plagioclase.
Specimens: The largest stone has a weight of 354 g.
Shock stage: C-S3
Weathering grade: W3/4
Classifier: K. Metzler, IfP.
This lot comes with certificate of authenticity.
