    • The dilemma of asymmetric porphyroclast systems and sense of shear 

      Zhang, Qing; Fossen, Haakon (Elsevier, 2020-01)
      Asymmetric porphyroclast systems have long been used as independent shear-sense indicators based on their clast-tail asymmetry and/or stair-stepping tail geometry. Over the last two decades, advances in exploring the ...
