Norouzi overpowered wrestlers from China, Bulgaria, Kazakhstan and Japan before defeating Georgia's Lashkhi in the first and second periods with similar results of 1-0 in the final and earning a gold medal.
Norouzi's medal was Iran's second gold in the London Olympics.
On Sunday, Iran's five-time world champion Hamid Sourian Reihanpour won the country's first gold medal in the London Olympic Games after defeating Azerbaijan's Greco-Roman wrestler in the 55kg category Rovshan Bayramov in the final match.
Sourian had a wonderful start in the London Games and won wrestlers from Hungary, Kazakhstan and Denmark before meeting Bayramov in the final.
The 26-year-old Iranian genius won both times 2-0 and 1-0, respectively.
Sourian's medal was not just Iran's first gold in the London 2012 Olympics, but the country's first-ever Greco-Roman wrestling gold medal in Olympic games throughout the history.
Iran's weightlifting world champion Kianoosh Rahmati had also earlier earned a bronze medal in the London Games.
USD 165,000-state rewards will be waiting for Iranian gold medal winners as soon as they return home.
