The Structural and Stress Analysis of Hemrin North Structure, North of Iraq.

The study focused on the results of first paleostress from thrust fault slip data Tertiary age Hemrin North Structure, Iraq. stress inversion was performed for using an improved right dihedral model, and then followed by rotational optimization (Georient Software). trend principal axes (σ1, σ2 σ3) ratio differences (R) show main field is NE-SW compression regime. As well as Lisle graph Mohr diagram to determine magnitudes palestress. values area were σ1=1430 bars, σ2=632 bars σ3=166 bar. large primary could be attributed active tectonic processes that caused pre-Tertiary deformation.
