<< I am slightly confused. Are all metoerites considered gaseous or is it just a certain group of metoerites? Any good reading on the subject? >> All meteorites contain gasses locked into their crystal structure. There are some however that are considered "gas rich". Gas rich meteorites have spent time on the surface or within 1mm of the surface. Over time the solar wind implants gasses on to the exposed surfaces. Howardites are good candidates for gas rich meteorites because they are considered to be asteroidal soil. However not all howardites are gas rich, in fact most are not. An example of a gas rich howardite is Bununu. I don't have any refereneces, but maybe Bernd can help.
