Banhadao is a multiple intrusion of some 11 km2 intruding the Tres Corregos granitic complex.
Barra do Teixeira is a small phonolite plug intruding the Precambrian Tres Corregos batholith. Sete Quedas is a similar phonolite plug some 10 km to the east.
This is a body of about 4.5 km2 elongated northwest-southeast and intruded into Precambrian granites of the Tres Corregos complex.
This carbonatite intrusion is situated only 2.3 km southeast of Itapirapua (025-00-103) and forms a plug over 500 m high surrounded by precipitous cliffs; it is about 2 km2.
The Mata Preto complex is intruded into the Precambrian metasediments of the Acungui Group and Tres Corregos granites but shows little topographical expression.
Small phonolite plugs are found a few km north and northeast of Cerro Azul.
Tunas comprises four coalescing intrusions covering 25 km2 which are cut by three intrusions of volcanic breccia. Several phonolite dykes up to 200 m thick extend to the northeast and southwest.
An oval-shaped complex of about 1 km diameter. Olivine gabbro and phonolite are present but little information is available.
The complex of Jacupiranga is an oval-shaped intrusion of 65 km2 emplaced in mica schists and granodiorites of the Precambrian Acungui Group, which are fenitized and nephelinized in places.
