Chemical Composition Of Cement And Zeolitic Tuff Download Scientific Chemical composition of the zeolitic tuff samples. representative samples of zeolitic tuffs from măcicaş, aluniş and apahida occurrences (cluj county, romania) were investigated. The present paper assesses petrographic, mineralogical, chemical, and technological features of different zeolitic tuff samples from various western usa districts of the basin and range province containing mainly erionite, mordenite, clinoptilolite heulandite and phillipsite.
Chemical Composition Of Cement And Zeolitic Tuff Download Scientific This paper presents the results of mineralogical and chemical investigations of the zeolitic tuff from the slanci deposit. structural parameters of the heu‐landite mineral present in the tuff are also reported. Chemical composition: the zeolitic tuff samples zr, z, zd and zt were characterized by x ray fluorescence technique. the percentages of metal oxides in the zeolitic tuff samples are shown in table 2. Whole rock xrf analyses for 12 samples of vitric tuff are listed in table 3. since the tuffs consist mainly of altered volcanic glass, their original chemical composition should approximate that of the volcanic eruptive rocks from which they were derived. Xrd analysis of volcanic tuff samples revealed that most samples are composed of phillipsite as major constituents followed by chapazite and faujasite. each one has own specific gravity and due to that phillipsite, chapazite and faujasite can be separated from each other.

The ert sample presents the following zeolitic terms: erionite (iccd #88 1223), clinoptilolite and chabazite. the results obtained by the mineralogical characterization of the zeolitized tuffs, limited to crystalline phases are summarized in table 3. The chemical composition of the zeolite rich tuff is given in table 1. the total sio, and a1,o, content, which are the main constituents of the geopolymeric reaction, is 78.8% and it is within the range of values reported by davidovits (1994) [30]. The chemical composition of the samples in their natural state was determined by x ray fluorescence (xrf). compounds such as sio2, al2o3, cao, na2o, k2o, mgo, fe2o3, tio2, and mno were found. The results of chemical analysis of the zeolite tuff rock samples are presented in table 2. according to their chemistry, all tuffs studied exhibit shoshonitic affinity and trachytic composition (figure 2).
