Summary:

The texture and chemistry of three petrographically distinct styles of altered glasses -- two hyaloclastites and one hylaotuff, were studied in an effort to better understand the mechanism by which alteration of sideromelane and formation of palagonite occurred in these samples. This was done by using a combination of electron micro-probe analysis, transmission electron microscopy, high-resolution transmission electron microscopy, and scanning electron microscopy.
