The paleomagnetic investigation is carried out in the eastern part of lake langano-ziway, MainrnEthiopian Rift. The aim of this paleomagnetic study is to quantify vertical axis rotation.A total ofrn11 paleomagnetic samples were sampled from outcrop of basalt, ignimbrites and rhyolite flowsrnranging in age from 2ma to 0.1ma. The paleomagnetic specimens are subjected to progressivernalternating field demagnetization, thermal demagnetization and impulse magnetization. Inrngeneral, the directional analysis showed either one or two components of Natural RemanentrnMagnetization (NRM) to characterize the wholemeasurements. The low stability components arernremoved by alternating fields up to 15mt or by heating up to 300oC. The high stabilityrncomponents are isolated above those steps and vector is directed towards origin, and itrnrepresented by Characteristic Remanent Magnetization (ChRM). The principal componentrnanalysis and site mean directions calculation yielded normal and reversed polarities. An overallrnmean direction calculated from individual site mean directions are Ds=354.1o, Is=8.3o, N=11, Krn=22, Î±95=10o, with an angular difference of -7.8 Â± 8.24 and the negative value indicate thernrotation is counter clock wise.The comparison of this result with the mean expected referencerndipole geomagnetic field direction (Ds=1.9, Is=13.5, N=32, K=105.6, andÎ±95 =2.5), from thernapparent polar wander path reference curve for Africa at 1.5 ma (Besse&Courtillot 2003), foundrnto be statistically different. This would imply that the area is at the contact of central and riftrnmargins with small rotation. These results indicate that the late Pliocene-Pleistocene rocks of thernMER in the study area show small vertical axis rotation, argue transtensional and seafloorspreading-rntransform kinematic models. It is therefore, suggested that large offset faults, producernthe right stepping, en echelon magmatic segments of the MER, which is at the transition fromrncontinental to oceanic extensionrather thanmagma intrusion.
