carbon has two non-radioactive isotopes, and in material from the solar system, including most meteoritic minerals, these are mixed in a well-known ratio.
碳有两个非放射性的同位素,在太阳系的物质中,包括在大多数的陨石矿石中,它们的混合比例是众所周知的。

古侵蚀面之上发育铁、铝质泥巖,古侵蚀面之下发育大气淡水溶蚀带;
geochemical investigation reveals that the ore-forming fluids originated from the mixing of magmatic formation and meteoritic water.
成矿流体为巖浆水、变质水和大气降水的混合液。
in addition, over 30 tons of meteoritic iron in small chunks covered the plain when europeans first discovered the crater.
