Argillic alteration constitute exploration objectives for epithermal and porphyry-type deposits. Argillic alteration exhibits lateral and down zonation that can be divided into mineral assemblages. These assemblages were as follows: silicified zone (silica cap), quartz+ kaolin minerals + alunite zone and K-feldspar + illite + montmorillonite zone.On the basis of geochemical and mineralogical characteristics, the hydrothermal fluids that formed the kaolin deposits were acidic.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659278501\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659278501","offer_id":39429707464797,"sku":"9783659278501","price":39.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/e8917df3-77be-43f9-b327-02d4226e0c0b.jpg?v=1773382615","url":"https:\/\/shop.autorenwelt.de\/products\/kaolin-deposits-mineralogical-geochemical-and-isotopic-properties-von-sedigheh-zirjanizadeh","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
