Writeup from MB 109:
Northwest Africa 13364 (NWA 13364) Morocco Purchased: 2019 Classification: Carbonaceous chondrite (CV3) History: The 227 g sample was purchased from Aziz Mouadine at the St. Marie aux Mines show in June, 2019. Physical characteristics: Sample is dark-brown in color and has a blocky irregular shape. The exterior is devoid of fusion crust and chondrules are visible on the weathered exterior. The interior of the sample has a matrix that is a mixture of mottled gray and dark-red with lighter-colored chondrules and CAIs. Petrography: Description and classification (A. Love, App) Sample has a chondritic texture composed of chondrules and CAIs and abundant AOA’s set within an opaque matrix (~52 vol%). Chondrules have an average apparent diameter of 658 µm (n=56). Some pyroxenes contain ferroan olivine veins (Fa23-41). Additional minerals are: anorthitic plagioclase, hedenbergite, diopside, chromite, rare troilite, Ca-phosphate, and secondary calcite. Geochemistry: (A. Love, App) Olivine (Fa6.0±5.7, Fe/Mn=12.5-116.7, n=16); low Ca pyroxene (Fs1.1±0.2Wo0.9±-0.2, n=6). Classification: Carbonaceous Chondrite (CV3) Sample is an unequilibrated CV carbonaceous chondrite based on modal abundance of matrix, mineral compositions, chondrule diameter and magnetic susceptibility. Specimens: Marc Jost (SJS) holds the main mass. An encut and part slice weighing 31.57 g and a polished thin section are on deposit at App. | ||||||||||||||||||||||||||||||||
