1. Epidermal morphology of the cordaitalean leaf Noeggerathiopsis brasiliensis nom. nov. from the southern Paraná Basin (Lower Permian, Rio Bonito Formation) and paleoenvironmental considerations
Abstract A Brazilian cordaitalean leaf is reassigned and redescribed based on cuticular analysis. The new name Noeggerathiopsis brasiliensis is erected as a replacement for Rufloria gondwanensis Guerra-Sommer. The leaf adpressions come from a tonstein layer within a Sakmarian coal seam of the Faxinal Coalfield, southern Paraná Basin, Brazil (U-Pb SHRIMP mea

2. Pyrite utilization in the carboniferous region of Santa Catarina, Brazil - Potentials, challenges, and environmental advantages
Abstract The main coal seams explored in the coal region of Santa Catarina are Barro Branco (BB) and Bonito (BO). Owing to the association with the mineral matter, the tailings generated in the beneficiation are arranged in disposal areas, and subject to the generation of acid mine drainage (AMD). The objective of this study was to evaluate the use of pyrite

3. Estudo tecnológico para beneficiamento do carvão da camada Bonito, SC
The coal from Barro Branco seam, which is widely used, is situated in the southern Brazil, State of Santa Catarina, and it is reaching depletion. The remaining coal from Bonito seam in the same region is less known and is characterized by the high percentage of near-gravity material and ash content. This peculiarity makes it difficult to treat in the current

4. Methodology to estimate the in situ uniaxial compressive strength of coal seams based on geophysical data / Proposta para a estimativa da resistência à compressão uniaxial in situ de camadas de carvão com a utilização de geofísica
A arte de dimensionar pilares em minas subterrâneas de carvão tem sido objeto de pesquisa há mais de 100 anos no mundo inteiro. A maioria dos métodos de dimensionamento de pilares para a lavra segundo o método "câmara e pilares" se vale de parâmetros de resistência e geométricos das camadas de carvão. A resistência in situ da camada de carvão (S1
