Abstract
<p>Major and trace elements analysis, U-Pb zircon dating, rare earth elements (REE) analysis and SrNd isotope analysis were conducted on samples from the Haki Granodiorite in the eastern part of northern Kyushu, Southwest Japan. This granodiorite is composed mainly of porphyritic medium-grained hornblende - biotite granodiorite, and divided into two facies: main facies and hornblende porphyritic facies. U-Pb zircon age of 106.64 ± 0.82 Ma is obtained from the main facies of this granodiorite. This age similar to that of the Ochiai Granodiorite. Major and trace elements, REE and Sr-Nd isotopic compositions of this granodiorite also similar to those of the Ochiai Granodiorite. Thus, the source magma of the Haki Granodiorite is the same as that of the Ochiai Granodiorite.</p>
