Depletion patterns in the absorbing gas of GRB 120327A, taken from average gas-phase abundance measurements in warm halo (black dotted line), warm disk + halo (red solid line), warm disk (blue long-dashed line) and cool disk (green short-dashed line) clouds of the Milky Way (Savage & Sembach 1996). Filled black circles represent our data points, which are best fitted by the warm halo cloud pattern. Si and Mg are clearly over-abundant.
