The significance of carbonate in meteorites from Mars is that they contain water.
Yes. The thin atmosphere of Mars and low rates of weathering means that there are probably more intact meteorites on Mars than on Earth.
Yes. The Mars probes have photographed a meteorite on the surface of Mars. See related link below.
Meteorites formation.
Meteorites fall into two classes, stony and iron. There is a belt of meteoric material near Mars, from which many of our meteorites come. Perhaps the debris from a broken planet? The iron meteorites, in fact iron-nickel mixtures, are magnetic. the stony meteorites are not. Have a look for Bode's Law in a reference source.
Mercury, Venus, Earth, and Mars all have impact craters.

From Wikipedia, article "Martian meteorite": These meteorites are thought to be from Mars because they have elemental and isotopic compositions that are similar to rocks and atmosphere gases analyzed by spacecraft on Mars.
The diameter of meteorites varies greatly, from the size of a grain of sand to the size of Mars (speculated).
Yes. The Mars probes have photographed a meteorite on the surface of Mars. See related link below.
Yes. In fact, scientists have found meteorites here on Earth that appear to be pieces blasted off the surface of Mars when some much larger object hit it!
Martian meteorites were ejected from the surface of Mars during massive asteroid and comet impacts.

Most meteorites are believed to Originate in the asteroid belt between Mars and Jupiter.
