Fig 5 - Impact-related melting of sedimentary target rocks of the Rubielos de la Cérida structure in Spain

Fig. 5. X-ray powder diffractogram of the silicate melt rock shown in Fig. 4. Beside the sharp diffraction peaks belonging to the feldspar phase ( f ), strongly broadened mica peaks ( m ) can be observed. The broadening reflects the low crystallinity of this phase. A typical glass “hump” is visible in the 2 -range between 20° and 30°, with peaks of feldspar and mica phases superimposed. (Measurement was carried out using a Philips PW1710 diffractometer with secondary monochromator. Operating conditions for the x-ray tube: 40 kV accelerating voltage, 30 mA beam current on a copper anode. Measuring conditions: range 4 ≤ 2 θ ≤ 100 ° ; stepwidth ∆ 2 θ = 0.02 ° ; time/step 2 s. Phase analysis was carried out using MDI-JADE+ program and ICDD database).
