Ambohimirahavavy Complex


Mixed intrusive and extrusive complex about 18 km long forming a mountainous area and including an outer intrusion of granite which may be ring dikes (Donnot, 1963) and an inner complex of volcanic rocks.

The alkaline intrusions of the Ampasindava Suite are exposed on the Ampasindava Peninsula and its surroundings. They mainly include Miocene to Oligocene gabbro, nepheline syenite, syenite, quartz syenite, and alkaline granite intrusions, with Mesozoic sedimentary rocks forming the surrounding area. The northeastern and southeastern parts of the Ampasindava Peninsula are primarily composed of the Ankaizina volcanic group, ranging from basalt to phonolite-trachyte. This region has a tropical humid climate, with an average annual temperature between 20 °C and 27 °C and an annual rainfall of approximately 1500 mm. This climate supports dense vegetation and the formation of thick weathering layers.
The Ambohimirahavavy complex is one of the four major alkaline complexes on the Ampasindava Peninsula (together with Manongarivo, Bezavona, and Andranomatavy). It consists of silica-undersaturated or oversaturated volcanic and intrusive rocks, including quartz syenite and syenogranite intrusions in the northwest, and circular syenite intrusions containing nepheline syenite, quartz syenite, and granite in the southeast.
