东古变质地体位于日本西南部九州岛中部西部，长约40公里，最宽20公里。该变质地体从北向南可划分为三个不同的单元（如Karakida， 1992）。它们分别是马诺塔尼变质单元、Higo变质单元和龙合山变质单元。马诺塔尼变质单元由碱角闪洞和长石等高p /T变质岩组成（Karakida et al., 1989）。龙合山变质单元具有强烈的糜棱岩化作用和低p低t变质作用（Yainamoto, 1962）。与此相反，Higo变质单元由高t变质岩和变质岩组成，直至含无水铁矿的超高温粒粒岩相（Yamamoto, 1983; Obata et al., 1994; Osanai et al., 1996, 1998）。马诺塔尼变质岩单元与Higo变质岩单元的边界为逆冲断层，并伴有蛇纹岩侵入；Higo变质岩单元与龙河山变质岩单元的边界为Miyanohara变质岩（c. 210 Ma; Kamei et al., 1998）和白石野花岗闪长岩（c. 120 Ma; Kamei et al., 1997）的花岗岩体（Higo深成杂岩）侵入。在Higo变质单元的南端，角闪辉长岩和角闪斜辉长岩（约257 Ma）未发生任何变形，也以小块状出现。在西北部的Higo变质岩
The Higo metamorphic terrane, located in the western part of central Kyushu island, south-west Japan, extends for about 40 km in length and has a maximum width of 20 kin. This metamorphic terrane can be divided into three distinct units (eg Karakida, 1992) from north to south. These are the Manotani metamorphic unit, the Higo metamorphic unit and the Ryuhozan metamorphic unit. The Manotani metamorphic unit consists of high-P/T metamorphic rocks including alkali-amphibole and lawsonite (Karakida et al., 1989). The Ryuhozan metamorphic unit is characterized by intense mylonitization and low-P low-T metamorphism (Yainamoto, 1962). In contrast the Higo metamorphic unit consists of high-T and metamorphic rocks up to ultrahigh-temperature granulitefacies with anatexite (Yamamoto, 1983; Obata et al., 1994; Osanai et al., 1996, 1998). The boundary between the Manotani and the Higo metamorphic units is a thrust fault accompanied by serpentinite intrusion while those of the Higo and the Ryuhozan metamorphic units are bounded by intrusions of granitic rocks (Higo plutonic complex) of the Miyanohara tonalite (c. 210 Ma; Kamei et al., 1998) and the Shiraishino granodiorite (c. 120 Ma; Kamei et al., 1997). In the southern end of the Higo metamorphic unit hornblende gabbro and hornblende-clinopyroxene gabbro (c. 257 Ma) without any deformation aIso occur as small masses. In the north-western part of the Higo metamorphic
