Diagenetic Alteration Of Perlite In The Guryongpo Area

Mordenite, associated with clinotpilolite-K, is a replacement product of vitric tuff and perlite, and a common phase in cavities and fractures in the tuff beds in the Guryongo area, Korea (Noh and Boles, 1989). The pyroclastic rocks are interbedded with lacustrine shale, siltstone, and coal beds.

properties of perlite rims and obsidian cores appear to contradict this assumption. Today the problem of hydration-rind dating is no longer centered about the earlier question of syngenetic versus diagenetic formation of hydration rinds, but rather in the rate formula which is used for diagenetic …

Gemstones form in metamorphic, magmatic, and sedimentary rocks. In sedimentary units, these minerals were emplaced by organic and inorganic chemical processes and also found in clastic deposits as a result of weathering, erosion, transport, and deposition leading to what is called the formation of placer deposits. Of the approximately 150 gemstones, roughly 40 can be recovered from placer ...

(1967) concluded that palagonite is an alteration product of mafic volcanic glass. Bonatti (1965) believes that most palagonite is formed at high temperatures (during syngenesis) and that low-temperature palagonites (diagenetic) are rare. He based most of his conclusions on the work done by Marshall (1961). The latter estimated

Syngenetic and diagenetic tensile failure in basaltic glass (low silica glass) is pervasive and provides abundant alteration fronts deep into the glass structure. Perlitic fracturing in obsidian (high silica glass) limits the alteration zones to an onion skin geometry. Borosilicate waste glass
