Laser technology

Gypsum’s crystalline facies and sample handling. Images of the studied twinned selenite crystal and of the sample preparation and handling for optical microscopy, SEM-EDX, and LIMS analyses. (A) Smal crystal selenite (SC) and decimeter-sized twinned arrow-head selenite (TS) crystals show the darker re-entrant angle of the crystals (dashed black lines). (B) Large petrographic thin section of the re-entrant angle of the twinned selenite crystal marked in the blue rectangle in (A). It shows very turbid (vTL), turbid (TL) and limpid laminations (LL). (C) Small petrographic thin section of turbid laminae fixed on the LIMS sample holder with copper tape. (D) Gold coated sample on the LIMS sample holder.
