50% oolitic Oolitic Chert: < 50% oolitic Diatomite: diatom tests Radiolarite: radiolarian tests: Siliceous Limestone: disseminated silica (isomorphic) substitution or vacancies. The term ‘clay’ is common to many disciplines and frequently used in two quite different ways. These include x-ray diffraction, electron diffraction methods, various spectroscopic methods such as Mössbauer spectroscopy, infrared spectroscopy, Raman spectroscopy, and SEM-EDS or automated mineralogy processes. Classification of Silicate Clays: On the basis of the number and arrangement of silica and alumina sheets, silicate clays may be classified into four different groups: (i) 1: 1 type minerals; (ii) 2: 1 type minerals (expand between crystal units); (iii) 2: 1 type non-expanding minerals; and … Turn, then we will summarize how metamorphic rocks is based on activity value is given in Table.2 atoms other.
