Geological Setting Clause Samples
The Geological Setting clause defines the physical and geological characteristics of the area relevant to the agreement or project. It typically outlines details such as rock types, soil composition, fault lines, and other subsurface features that may impact construction, mining, or exploration activities. By clearly describing the geological context, this clause ensures all parties have a shared understanding of site conditions, helping to allocate risk and inform planning or operational decisions.
Geological Setting. The regional geological setting of Madagascar has a bearing on the copper mineralisation (Fig.3). Madagascar was formerly attached to the African continent as part of the Gondwana supercontinent. The supercontinent broke up during the mid- Jurassic to mid-Cretaceous. Madagascar was first disconnected from the Kenya- Somalia part of the African continent during the Middle to Upper Jurassic by rifting within what is now the Mozambique Channel. Later, during the Upper Cretaceous, a new dislocation took place between lndia and Madagascar. There were several volcanic episodes due to rifting which resulted in the eruption of extensive basalt lavas, principally during the Upper Cretaceous, when Madagascar was ultimately separated from India. The resulting flood basalts are believed to have covered the entire surface of the island. Remnants of the volcanic pile are now preserved in the Mesozoic sedimentary basins of the west coast, namely the Morandava Basin, the Majunga Basin. The Maintirano copper project area is located on these Cretaceous flood basalts within the Majanga Basin (Fig. 4). All copper occurrences observed and recorded in the area lie within mapped Cretaceous basalt. In most occurrences observed the copper mineralisation occurs as green secondary copper minerals, including malachite (copper carbonate), chrysocolla (copper silicate) with minor azurite. Cuprite (copper oxide) is recorded in several occurrences. Traces of native copper occur and some quite large native copper specimens (4 cm diameter), reportedly collected from the area, were observed. In most of the occurrences observed the copper mineralisation lies within sub horizontal vesicular zones within the basalts, very likely representing the tops of individual lava flows. In two occurrences observed, the Sicilian and Ralf Point 1 (Fig. 6), mineralisation appears to be within steeply dipping zones, probably in joints and fractures. Cuprite is reported to have been mined on artisanal scale in at least two locations. In occurrences observed, Tsarandaba and Belitsaka, widespread green copper mineralisation in vesicles in basalt can be traced for considerable distances along the hillsides of flat basalt plateaus, with observed stockpiles and pits evidence previous small-scale mining. The copper occurrences within the basalts are virtually un-explored with sparse publications on the work complete in the Maintirano area. There has been small-scale mining by Chinese and Korean companies but the to...
Geological Setting. Sediment-hosted, "C▇▇▇▇▇-type" gold systems account for the vast majority of the gold production in Nevada and for most economic gold discoveries made since 1975. Mineralization in these environments lies mainly in four geographic belts of mostly Paleozoic carbonate rocks. These belts are located in north-central Nevada, and the three most productive pass through the townsites of Carlin (“C▇▇▇▇▇ Trend”), Battle Mountain (“Battle Mountain-Eureka Trend”) and Golconda (“G▇▇▇▇▇▇▇ Trend”). The fourth belt, the “Independence Trend”, is located north of the town of Elko and is the location of the Jerritt Canyon group of mines (Queenstake Resources) and the Big Springs Mine (Golden Gate Resources). Collectively, these belts hold a geochemical endowment of over 200 million ounces of gold. Northern Nevada’s geology is complex, but is dominated by Basin and Range brittle, extensional tectonics resulting in the characteristic northerly-trending basins and ranges throughout the state. In the ranges (h▇▇▇▇ blocks), marine sedimentary rocks are exposed spanning the entire range of Paleozoic rocks that are complexly thrust, intruded by younger Cretaceous intrusions. and both intruded and capped by Tertiary-age volcanic rocks. Of primary interest to the P▇▇▇▇▇ mineral system are the lower Ordovician rocks of the Comus Formation and the underlying Cambrian P▇▇▇▇▇ Formation.
Geological Setting. The PSA block lies in the SW part of the Corozal Basin, northern Belize. The basin is an eastward extension of the oil and gas productive Northern Peten Basin of Guatemala. The Corozal Basin was part of a rift basin in the Jurassic but by the early Cretaceous had evolved into an intracratonic sag basin and shallow carbonate platform. From the early to the mid Cretaceous carbonate platform sedimentation was characterized by alternating sequences of dolomite and anhydrite. Important reservoir quality sandstone units occur along the basin margin where this PSA is located.
