A meteor is a bright trail or streak that appears in the sky when a meteoroid coming from space is heated to incandescence by friction with the earth's atmosphere. Therefore the composition of a meteor is the same as the composition of the incoming meteoroid.
If the meteoroid does not survive its passage though the atmosphere we do not for sure know what its composition may have been.
However if it does survive and lands as a "meteorite" we can collect it and analyse its composition.
Work with meteorites has found a variation in composition as you can find out from the related link below.

The suffix "meteor" is typically used to indicate a connection to meteors or meteorites, such as in the words "meteoric" (resembling a meteor) or "meteorite" (a fragment of a meteor).
A visible meteor is a meteor that can be seen by the naked-eye
Meteor Rain? Are you thinking of Meteor Mash or Draco Meteor or are you playing Pokemon Black & White
Rocks are made up of minerals. Different rocks consist of different minerals in different proportions.
I think you are mistaking "meteor blast", for meteor mash, or Draco meteor. Arceus can't learn meteor mash, but can learn Draco meteor by leveling it while it's holding the Draco plate.
