@Earthworm of course, but my question is the bulk chemical composition of the incoming meteor and cosmic dust

Then just look up what ordinary and carbonaceous chondrites are made of, and you're set to go..

I would like to know, if there is an estimate of chemical composition of mass. That is , I am looking for a categorization of this mass in x% Carbon, y% Silicon, etc.

Thank you.
