| 英文摘要 | A better understanding of the fractionation properties of carbon isotope between different carbon-bearing minerals will provide insights into the core-forming process of planets. In this study, we carried out an integrated study of petrography and in situ secondary ion mass spectroscopy (SIMS) carbon isotopic analysis for Nantan and Aletai iron meteorites. Haxonite in Aletai IIIE-an iron meteorite has a delta C-13 value of -14.80 +/- 2.31 parts per thousand, which is different from that of haxonite in Colonia Obrera IIIE iron meteorite. This suggests that the parent body of Aletai has a different initial carbon isotopic composition or experienced different planetary processes (e.g., degassing of CO2/CH4). A graphite-rich nodule in Nantan IAB iron meteorite, characterized by a core-mantle-rim texture, was systematically studied. Some graphite grains in the nodule mantle (GNM; delta C-13 value as low as -14.65 parts per thousand) and all graphite grains in the nodule rim (GNR: delta C-13 = -12.65 +/- 2.90 parts per thousand) are more depleted in C-13 than those in the nodule core (GNC; delta C-13 = -7.17 +/- 2.42 parts per thousand). This could be due to the preferential incorporation of C-13 into the early-crystallized GNC. The carbon isotopic fractionation (Delta C-13 = 6.9 +/- 2.7 parts per thousand) between coexisting GNR (delta C-13 = -12.65 +/- 2.90 parts per thousand) and cohenite (delta C-13 = -1 9.60 +/- 2.59 parts per thousand) yielded an equilibrium temperature of similar to 950-1310 degrees C, supporting the melt-crystallization genesis for nodule. We concur with previous studies that the early differentiation of Earth could have led to positive carbon isotopic fractionation between graphite/diamond in the mantle and metallic melt sinking to the core. |
