Writeup from MB 111:
Loulan Yizhi 042 ~40°30’N, ~89°40’E Xinjiang, China Find: 2019 Classification: H/L-melt rock History: (Ziyao Wang) Ai Li Kayiti discovered this stone close to Loulan Yizhi in 2019 while they were searching for archaeological objects, sold it on the Shanshan market to Ziyao Wang, and donated it to R. Bartoschewitz. Physical characteristics: Single brown stone of 22.9 g Petrography: (R. Bartoschewitz, Bart) granular texture of hypidiomorphic olivine 100-500 µm (~50%), pyroxene laths up to 1500 µm (~30%), feldspar, and intergranular devitrified glass with chromite grains. Metal and sulfide specks up to 5 µm occur in all mineral phases. Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa20.6 (Fa16.8-23.8; Fe/Mn=42-56; n=18); low-Ca pyroxene Fs21.1Wo3.9 (Fs21.2-22.9Wo3.4-4.8); Fe/Mn=27-34; n=7); pigeonite En56-70Fs22-32Wo8-12 (n=7); feldspar An6-17Or4-12 (n=15); chromite CRAL80-88, FFM74-80 (n=11). Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 4.19. O-isotopes (A. Pack and T. Di Rocco, UGött): δ17O(‰) = 4.439, δ18O(‰) = 6.840, D’17O (0.528) = 0.830. Classification: H/L melt rock (OC based on Fe/Mg vs. Fe/Mn of olivine and O-isotopes, H/L due to Fa/Fa and O-isotopes) Specimens: 4.74 g on deposit at Kiel, main mass and polished thin section with Bart, 2 g with Ziyao Wang. | ||||||||||||||||||||||||||||||||||||||
