# Correction: Corrigendum: Possible generation of heat from nuclear fusion in Earth’s inner core

### Subjects

The Original Article was published on 23 November 2016

The original version of this Article contained errors resulting from the incorrect calculation of formation energy in Equation 6. In the Abstract,

2D + 2D + 2D → 21H + 4He + 2 + 20. 85 MeV. The possible heat generation rate can generation rate can be calculated as 8.12 × 1012 J/m3”.

2D + 2D + 2D → 21H + 4He + e- +  + 21. 63 MeV. The possible heat generation rate can generation rate can be calculated as 1.27 × 1015 J/m3”.

In addition, there was an error in the ‘Introduction section’, where

“Increase in paraeomagnetic magnitude between 2.7–2.1 billion years”

“Increase in palaeomagnetic magnitude between 2.7–2.1 billion years”

There were also errors in Equations 6, 7, 9, 10 and 11, which now read:

There were also errors in Equations 23, 24, 25 and 26 which now read:

Under the sub-heading “Existence of a D-rich inner core”,

“On the other hand, because the incorporated gross weight of D from the creation of Earth’s core to present time is estimated as 6.67 × 1021 kg (=100 Mkm3 × 2 Mg/m3 × 4/20 × 1/0.006), the volume of Fe-D crystals up through the present is 4.99 × 1017 m3 (6.67 × 1021/13.36 [Mg/m3]), resulting in an unreacted (Fe-D) crystal volume of 4.37 × 1017 m3 (=4.99 × 1017 − 6.23 × 1016)”.

Finally, there was an error in the ‘Conclusions’ section where:
