Description:
Geologic observations and paleo magnetic studies of the western and eastern Palu Bay was undertaken, in order to study the extent of rotated areas and to develop constraints on tectonic models concerning the formation of this bay. Characteristic of remanent magentization (ChRM) results from Palu bay, the western show that; yield a pole at -39.116 ° N, 119.895 ° E with R=13.99, α 95 =0,42, D m /I m =61.76/-26.7 and the Eastern Palu bay show that; yield a pole at -81.855 ° N, 52.913 ° E, R=8.99, α 95 =0.29, D m /I m =67.1/-5.42. The granitic rocks in these areas are dominated by granite and Monzonit-Quartz in composition, with high-K calc-alkaline photasik (KAP) and show metaluminous-peraluminous affinity. This suggests that the rotational motion on both sides of the bay are similar during the Neogen.
