The 15th century altar, part of the Aztec empire's main temple, was uncovered last weekend near the city's main Zocalo square along with the 3.5 metre stone slab, most of which is still buried under earth.
"It is a very important discovery, the biggest we have made in 28 years. It will allow us to find out a lot more," Mr Encinas told reporters.
The altar has a frieze of the rain god Tlaloc and another figure related to an agricultural rite.

The Aztecs began building the Templo Mayor pyramid-shaped temple in 1375.
Its ruins are now only yards from downtown's choking traffic. It was first excavated in 1978 after electricity workers found an eight-tonne carving of an Aztec goddess.
Spanish conquistadors destroyed the temple when they razed the city in 1521 and used its stones to help build their own capital.
