Montmorillonite is a 2:1
phyllosilicate that belongs to the group of smectites and it is the main component of bentonite clay.
Continuum removal analysis is a particularly robust tool for detecting and predicting iron oxides and
phyllosilicate minerals.
This research describes new insight as to how this stone can be identified in hand sample in the field, such as detrital
phyllosilicate grains aligned parallel to bedding that are easily distinguished as silver flecks with a hand lens.
For the textural and chemical characterization of
phyllosilicates, sediments were prepared for transmission electron microscopy (TEM) study by two different methods.
In systematic mineralogy, kaolin, which is a thin clay, usually white in color, formed by the weathering of aluminous minerals, is classified as a
phyllosilicate, due to its absorption capacity and absence of primary toxicity (OWEN et al., 2012).
This composition is consistent with a silica-rich volcanic glass containing plagioclase and
phyllosilicate inclusions, together with secondary calcite veins.
Initially dispersed constituents of the granite are segregated into
phyllosilicate rich (P- rich) and quartz-rich (Q-rich) domains.
Geologic clay deposits are mostly composed of
phyllosilicate minerals containing variable amounts of water trapped in the mineral structure [1].
Clay is a natural mineral of the smectite family of
phyllosilicate group shaped crystals with a layered structure.
