'I do not think I fully realize yet what I have done. I feel great, but quite numb,' Mork said.
The 26-year-old Mork's 12-under-par round gave him a 36-hole total of 122. He shot 63 in the first round.
His total beat by three strokes the record shared by Tiger Woods and Frankie Minoza of the Philippines as the lowest 36-hole aggregate on any of the European, Challenge and Senior Tours.
It also beat Ernie Els' low 36-hole record of 18-under at the Heineken Classic in Melbourne in 2004.
'I have never been close to a 59 before. It is an honor to break so many records for European golf,' Mork said.
Mork began his round at the 10th hole and made six birdies to turn in 29 at 6 under.
But he made a double-bogey six at the second, only to eagle the third before closing with six successive birdies.
