Marques netted 10 of Brazil’s goals in a 12-5 win over Lithuania, who had come into this game having scored 21 times in their opening two wins in Group A.
Brazil raced into an 8-3 lead at half-time, as Lithuania looked second best throughout, before securing the victory after the interval to bounce back from their loss to Sweden in their previous match.
On his team’s goal-scoring hero Marques, Brazil coach Diego Goncalves Colletes said: ‘He really is one of the best players in the world. He is very young, only 23 years old, and we have really great expectations for him.’
Turkey’s men are guaranteed progression to the quarter-finals after recording their third straight win in Group A, having only conceded three times so far in the competition.
The Turks won 4-0 against European champions Finland, who gave away seven penalties in an error-strewn performance that enabled their opponents to take the win thanks to a hat-trick from Tuncay Karakaya.
In the other game in Group A, Great Britain's men's team took a point for the first time in Paralympic Games Goalball history in a tense 3-3 draw with Sweden.
Goals from Adam Knott, Niall Graham and Michael Sharkey helped the British team move 3-1 ahead, but Sweden fought back when Knott was beaten twice at the post by two accurate shots.
In Group B, meanwhile, Canada’s men produced a fine comeback from 4-1 down to beat the Republic of Korea 5-4 to record their first win of the tournament.
Brendan Gaulin scored a hat-trick and Mario Caron got one in the triumph and Canada coach Danny Snow said: ‘I asked the guys to hang in there. We adjusted to the game and they did a great job.’
Johan de Rick and Youssef Bihi both scored three times as Belgium won 8-6 against Iran, whose top scorer in the game was Seyed Mehdi Sayahi with three, and in the final game of day in Group B there was a 1-0 win for China over Algeria in a match where defences were on top and Yao Yongquan's goal was enough to decide the outcome.
In the three women’s Goalball games, defending champions USA lost 2-1 to Japan in Group D.
Six-time Paralympian Jen Armbruster gave the USA the lead midway through the first half before Akiko Adachi levelled and Masae Komiya netted a penalty to maintain Japan’s 100 per cent record in the competition so far.
Komiya said: ‘We are strong at defence so we just did what we can do, that's why it was a low-scoring game. Japan are cheering us on so we need to give them something to smile about.’
In the same group, substitute Marin Gustavsson’s brace helped Sweden fight back from a goal down against two-time Paralympic Games champions Canada to win 2-1.
In Group C, a Krista Leppanen double helped Finland’s women gain their first victory of London 2012 with a 3-2 win over Beijing 2008 bronze medallists Denmark, who have yet to pick up points in this tournament.
