D/H Ratio in the Interiors of Rocky Protoplanets Accreting in the Solar Nebula

The deuterium/hydrogen (D/H) ratio of primordial water partitioned into a planetary interior seems to be different on Earth and Mars. Water from volcanic rocks originating from Earth's deep mantle has a low D/H ratio with high 3He/4He ratios, implying that it was inherited partially from the so...
