The atomic-scale features of pressure-induced amorphized material are described for selected materials. Mössbauer spectroscopy parameters such as hyperfine magnetic and quadrupole interactions, isomer shift, spectral intensities, and f-values are applied in <SUP>57</SUP>Fe, <SUP>119</SUP>Sn and <SUP>129</SUP>I nuclei to elucidate features of the disordered phase such as changes in coordination number, density, relative abundance in the coexisting pressure range, magnetic features, and local-ordering. Those findings are supplemented by IR, Raman, X-ray spectroscopy, and X-ray diffraction. The materials discussed are some of the AB<SUB>4</SUB> molecular crystals, the antiferromagnetic four-fold coordinated FePO<SUB>4</SUB> and Fe<SUB>2</SUB>SiO<SUB>4</SUB>, and some preliminary data on the layer structured Fe (OH) <SUB>2</SUB>.
