The metal content of the interstellar and intergalactic medium is one of the most sensitive and significant imprints of the star formation history over cosmological time-scales. In current models feed-back mechanisms are crucial to explain the observed properties of galaxies. In a survey of X-ray properties of edge-on disk galaxies we have identified NGC 4634 as a target best suited to study the properties of an outflow governed by the distributed star formation. We propose to obtain X-ray spectra with significantly higher S/N to better constrain the metal content of the gaseous halo. We want to extract spatially resolved spectra which will allow us to discuss the enrichment and mixing processes and compare it with wind models.
