The Tocantins Gold Project, which is located near the town of Conceicao de Tocantins in Central Brazil, comprises a two exploration licenses totalling 14,329 hectares, covering Lower Proterozoic age greenstone lithologies that have been mined for gold sporadically since colonial times.
Approximately 75% of the gold enriched shear zones of Bullion Alley are hosted in porphyritic monzonite with the remaining 25% hosted in Inzana Formation (Takla Group) indurated volcanic and sedimentary lithologies. Several other syn to post-mineral vein types have been identified in drilling and in outcrops in the Bullion Alley zone.
The purpose of the survey work was to sample lithologies to establish a base geochemical signature as well as test the mobile ion (MI) technique in this area.
The lithologies and discontinuities encountered in bore holes, were identified and assessed for Tunnel construction and stability.
Tuffaceous debris and tuffite are widely distributed in sandstone, mudstone and carbonatite lithologies. Organic matter including mineral nutrients and aquatic organisms can increase bioproductivity, while terrigenous and aquatic organic matters determine kerogen types [17].
Recent prospecting on the Property has resulted in the discovery of numerous gold nuggets in 10 locations dispersed throughout the tenement from various stratigraphic lithologies. The property covers basalt dominated rocks of the Pilbara Well Greenstone belt.
2016-2018 scout-type drill holes, comprised of 22 individual holes drilled from 15 total drill sites, have importantly added to the knowledge of, and geological understandings of the permissive lithologies and favorable stratigraphy of the project.
The Catatumbo sequence studied in this research was deposited from Aptian to Coniaician, where succession of tectonic events along with right environmental conditions allowed sedimentation of several calcareous lithologies, resulting in a very rich petroleum system which have been producing hydrocarbon since the beginning of the last century.
The variation rules of the borehole stability of the 2# drilling path with the roof lithologies including a common roof, a hard roof, and a soft roof are shown in Figure 13.
A stratum is the place to store the geothermal energy where the thermal storage and conductivity vary significantly in different lithologies, and only the good stratum and lithology can store rich geothermal resources.
