According to semi-quantitative composition results at the site 1 (Table 2), the molar ratio Si/Al at the site is 1.51 which indicates a silica phase along with free quartz into the matrix.
Chemical Element Site 1 (wt. %) Fe 1.25±0.18 O 40.81±0.48 Al 22.41±0.24 Si 35.18±0.34 Ca 0.35±0.07 Fig. 3 shows the EDS spectrum of X-ray microanalysis at the site 1, probably into a vitreous phase, Fig. 2.

Elemental Analysis From SEM photomicrograph and EDS analysis of the selected samples, the gold was found to be interlocked with Al, Si and O which indicates the aluminosilicates.
ICP-OES results for elemental analysis after acid digestion Element Fe Al S As Concentration (g/t) 15641.8 5381.33 192.66 1174.26 Conclusions From the research work, mineralogical studies shows that gold was found associated with arsenopyrite, hematite, magnetite and quartz, where the majority of gold was found to be in aluminosilicates phase.

Pollak et al. [15] have studied some properties of SmPo by X-ray photoemission spectra and reported lattice parameter.
Jayaraman et al. [16] studied continuous and discontinuous semiconductor-metal transition in samarium monochalcogenides under pressure.

An essential component of the model introduced in this communication exploits a quantitative model for the coarsening of subgrain structures introduced by Holm et al. [5] which in turn built on earlier work on abnormal grain growth [6].

Owais et al. [1] stated that the air that was present inside the PCM coated composite affect thermal conductivity of fabrics.
On the other hand, Mao et al. reported that [12] there was a little change in fabric density and decreasing of thermal conductivity due to the effect of hydro entangling a wool web on to the surface of a knitted spacer fabric.

The transitional period of friction is usually influenced by microstructure and physical properties of matrix, phase transformation and transfer, temperature and ambient condition et. al., as mentioned in detail in the Ref. [5].
In these areas, a tribo-chemical reaction obviously happened due to frictional heat and surface shear stresses, which is quite different from the thermal reaction of Ti3SiC2, and some products may be different from which observed by Sun et. al. [4].
