The Borborema Pegmatitic Province (PPB), located in the Seridó region, has historically known occurrences of industrial minerals, gems, and rare elements (Li, Ta- Nb, Be and Sn) associated with pegmatites. However, the ...

The Borborema Pegmatite Province (PPB) is recognized for comprising a complex geological framework, encompassing several lithologies containing a set of mineralized pegmatites of industrial and gemological interest. However, ...

In order to mitigate the effects of drought and provide a more reliable water supply, both public and private-sector entities have attempted to utilize water wells across the semiarid regions of northeast Brazil. However, ...

Topological analysis can help in structural characterization, as well as in understanding the influence of connections on flow properties in reservoir rocks affected by deformation bands. In the present work, we used a ...

The demand for high purity feldspars, especially for use in the manufacture of porcelain tiles and whiteware, poses a challenge for the processing of the ore. Due to the need for very low levels of iron oxide (Fe2O3), ...

Problems related to the instability of oil wells such as agglomeration and accretion of cuttings lead to an increase in non-productive time in the operation of drilling, and careful selection of drilling fluid components ...

Acoustic tomography of cores can be rather useful on identification and quantification of several petrophysics attributes. Time-traveling tomography technique involves the inference of local acoustic velocity from the ...

The present document is about a master dissertation, where is presented all the development activities during the research. The silicification of carbonate and siliciclastic sediments can occur several times throughout ...

The Congo Shear Zone (CSZ) is considered to be a structural boundary that separates the Alto Moxotó (AMT) and Rio Capibaribe (RCT) terrains, both belonging to the Central Domain of the Borborema Province. Due to its ...
