Joubert previously took charge of Ireland's opening pool win over the USA in New Plymouth and their bonus point victory over Russia in Rotorua.
Rolland and Clancy will be the assistant referees for the England v France encounter on Saturday, with Clancy also running the touchline 24 hours later during the New Zealand v Argentina tie.
As announced in April, a panel of 10 referees and two specialist television match officials have been selected from the panel of 21 officials for the tournament's showcase matches which kick-off with the quarter-finals.
The appointments were made by the IRB's Match Official Selection Committee in Auckland on Sunday following a thorough review of performances across the 40 pool matches.
Wayne Barnes (England), George Clancy (Ireland), Craig Joubert (South Africa), Jonathan Kaplan (South Africa), Bryce Lawrence (New Zealand), Nigel Owens (Wales), Dave Pearson (England), Romain Poite (France), Alain Rolland (Ireland) and Steve Walsh (Australia) will perform referee and assistant referee duties.
Giulio De Santis (Italy) and Shaun Veldsman (South Africa) have been selected as the two specialist TMOs.

"The extensive performance review of all 40 matches included coach, match official and performance reviewer feedback and we are very happy with the way that the group has worked together to collectively achieve the goals set.
"Accuracy in decision making is our top priority. We will continue to work as a unit to achieve the high standards that have collectively been set and maintain a zero-tolerance attitude towards infringements across the key areas of the game.
"In that regard, I would also like to thank the coaches for their buy-in to the process during this tournament," he added.
IRB Match Official Selection Committee Chairman David Pickering commented: "This was a very tough selection process.
"The overall standard in performance has been exceptional and the team has achieved all that has been asked of them.
"And while it is inevitable that there are those who are unlucky to miss out on selection, I would like to thank all the referees, assistant referees and television match officials for their hard work, commitment and professionalism. They can be proud of playing their full part in contributing to what has been an exceptional Rugby World Cup."
The appointments for the Rugby World Cup semi-finals will be announced on Monday, October 10.
