It is not necessarily a comet if the ice/snow was from the impactor, because asteroids called chondrites have water and chondrites have high mass (approx 1000 kg chondrite found at earth because chondrites have iron in the Jilin meteorite shower) but there is no proof that it was a chondrite.

So the Martian atmosphere (100 times thinner than Earth's) still could cause a comet to evaporate (because the comet would start regelation and vaporize (due to the collision of air molecules in front of the comet creating pressure and heat. ) as it is more volatile than iron (2,862 °C), nickel (2,730 °C), copper (2,562 °C) and will condense and freeze (which will not make the bolders of ice ) which would also not cause the impact and seismic activity and If it was a comet the ice would not cling to the boundary of the crater but would rain from the cloud and be a bit larger in radius.
