Besides, it is proposed that the graphite veinlets formed through a complex partial melting process followed by a solidification toward the final eutectic transient coupled with the solid-state precipitation and later decomposition ordering of taenite. The presence of defects and taenite in graphite signal formation in a liquid environment. The \u03b413C values of graphite in the graphite-rich areas (e.g., ranging from \u22120.8\u2009\u00b1\u20091.7\u2030 to +15.3\u2009\u00b1\u20092.5\u2030) suggest a short-circuit diffusion path for C isotope fractionation.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>M.
