1. Ediacaran emerald mineralization in Northeastern Brazil: the case of the Fazenda Bonfim Deposit
Abstract The Fazenda Bonfim emerald deposit lies within the Seridó Belt. It is a classic example of deposit formed through metasomatic interactions between Be-rich granite intrusions and Cr(± V)-rich mafic-ultramafic rocks. The setting of the emerald mineralization was built under strong strike-slip dynamics, which produced serpentinization and talcificati

2. Petrologia do plúton granitico serra verde, porção lestre do domínio seridó
A área estudada situa-se na porção centro-leste da Faixa Seridó, na interface dos metassedimentos do Grupo Seridó e as rochas do embasamento cristalino do Complexo Caicó (RN). Dados petrográficos e qeoquímicos permitem definir os aspectos relativos à gênese e evolução do(s) magma(s) do Plúton Serra Verde, que constitui o alvo desta Dissertação

3. Análise de terrenos na porção setentrional da Província Borborema, NE do Brasil: integração de dados geológicos e gravimétricos
It is presently assumed that the Borborema Province resulted from a complex collisional process associated with the convergent movement of plates, possibly involving amalgamation and accretion of microplates. This process was consolidated at the end of the Brasiliano event. It is investigated the possible limits for the tectonostratigraphic terranes in the n

4. Estudos sedimentológicos e o contexto estrutural da formação Serra do Martins, nos platôs de Portalegre, Martins e Santana/RN
This dissertation deals with sedimentological and structural framework of the siliciclastic rock of the Serra do Martins Formation (FSM) in the Portalegre, Martins and Santana plateau, located to the south of Potiguar Basin, in the southwest and central Rio Grande do Norte state. This formation, regarded as of Oligo-Miocene age based on intrusive relations o

5. Mecanismos de alojamento de magmas granitóides :exemplo do plúton de Japi(RN)
This dissertation describes the igneous suites of the Japi granitoid pluton, intrusive in the Paleoproterozoic gneiss-migmatite complex of the eastern domain of the Seridó Belt, northeastern Brazil. Field relations show that the pluton is affected by strong deformation associated to the Brasiliano orogeny (known as the D3 phase) , with a NW-trending extensi

6. Petrologia dos granitóides brasilianos associados à zona de cisalhamento Remígio-Pocinhos(PB)
The Brasiliano Cycle in the Seridó Belt (NE Brazil) is regarded mostly as a crustal reworking event, characterized by transcurrent or transpressional shear zones which operated under high temperature and low pressure conditions. In the eastern domain of this belt- the so-called São José de Campestre Massif (SJCM), a transtensional deformation regime is ev
