A Brazilian court has suspended a government decree that would open up a vast natural reserve in the Amazon to commercial mining.
The area covers 46 000 square kilometres and is thought to be rich in gold, manganese and other minerals.
On Monday, following widespread criticism, the government revised the decree prohibiting mining in conservation or indigenous areas.
The latest decision follows an outcry from activists and celebrities.
The federal court in the capital Brasilia said in a statement it was suspending possible administrative acts based on the decree signed by President Michel Temer.
The Renca Reserve in the Eastern Amazon is home to indigenous tribes and large areas of untouched forest.
Its size is larger than Denmark and about 30 percent of it was to be opened to mining.
Mr Temer said this will boost the country’s economy.
