LINK<\/strong><\/a><\/p>\n“Mesosiderites are unique stony-iron meteorites, composed of eucrite-like silicates and Fe\u2013Ni metals. Their formation, including silicate\u2013metal mixing and metamorphisms, provide important insights into early planetary processes in the inner solar system. This report describes the first in-situ U\u2013Pb and Hf\u2013W dating of zircon in a mesosiderite Asuka 882023. The U\u2013Pb (4502\u2009\u00b1\u200975\u2009Ma) and Hf\u2013W (4532.8\u2009+\u20095.7\/-10.5\u2009Ma) ages may represent timing of the zircon formation, which is considerably younger than crustal differentiation of the parent body. This evidence, combined with earlier studies of chronology, implies that mesosiderites were reheated at 4530\u20134520\u2009Ma, clearly after the silicate\u2013metal mixing.”<\/p>\n","protected":false},"excerpt":{"rendered":"
