on a collision course

Of a person, group, or object, on a certain path to conflict, collision, destruction, or ruin with someone or something else.

Compared to liquid, our understanding of ice-phase microphysics is still poor owing to the complexity of ice crystal formation and growth, the diverse morphology of ice particles, the representation of ice melting, and the mechanisms of ice particle breakup (i.e., spontaneous, collisional, and rime splintering).
Complicated deformation history in the study area is related to the geodynamic setting of this region and collisional event in the Zagros orogeny (Agard et al., 2011; Mohajjel and Fergusson, 2000; Mouthereau et al., 2012).
