According to scientists, this is comfirmed by the complete identity of the ratio of titanium isotopes that have the geological formation of the Earth and moon. The ratios of isotopes of titanium-47 and titanium-50 received as the result of the study of fragments of lunar substances brought to Earth after the mission Apollo-11.
As a result, experts have found that titanium-47 and titanium-50 have almost the same ratio in terrestrial rocks.
钛-47和钛-50这两种同位素在月岩中的比率与地球岩石一致。样本来源于阿波罗11号带回的月岩。
同位素衰变是测定岩石年龄的重要指标,根据半衰期及岩石中同位素的比率可以测算出岩石的形成年龄。
故此项测定结果对于地月起源的证据,是具有重大意义的推进。
