Some Sedimentary and Structural Evidences of Ppossible Graben in Mawat-Chuarta Area, NE -Iraq
Iraqi National Journal of Earth Science,
2005, Volume 5, Issue 2, Pages 9-18
AbstractMawat –chuarta area has a complex geological setting, which is manifested by highly deformed mixture of all type of rocks, sedimentary , metamorphic and igneous. Through the area these rocks have penetrated, as tongue, in to the autochthonous rocks. In the southeast and northwest of the area two large normal faults are identified which have more than 500m of throw. The area between these faults (chuarta-mawat area) has suiffered clear subsidence as compared to the neighboring areas. This subsidence is attributed to the normal faulting accompanying graben. Much structural and sedimentological evidence are given to prove the presence of a graben . the evidence is striation. Slickenside, triangular facet , bitumen seepage, nappe of sedimentary and ophiolite rocks and thick accumulation of conglomerates.
