Limestone and Blue Granite Reserves

Limestone and Blue Granite reserves play an important role in a country''s economic growth. Rocks are deposited according to the topography of the area. Some oldest rocks can be found in the Canadian Shield, Australia, Africa and in a few other old regions around the world. The ages of these felsic rocks are around 2.5 and 3.8 billion years.

Granite and Granodiorite FAQ

 · Granite contains mostly potassium feldspars and has a low percentage of dark iron and magnesium minerals. In contrast, granodiorite contains more plagioclase (calcium and sodium) feldspar than potassium feldspar and has more dark minerals. Thus it is a darker color than granite. Chemical and x-ray analysis of granite and granodiorite can be ...

The deposit has a strike length of ~1800 m, persists down dip for ~600 m, varies from 2 to 17 m in thickness, averaging 8 m, and is lower grade, containing ~2% Cu. A small ore lense is also found in arkose below the Cobble Conglomerate where these beds abut the western granite ridge.

2.3 Granite-related mineral system | Geoscience Australia

2.3.1 Geological setting. Most deposits that form in the granite-related mineral system (Figure 2.3.1) are associated with felsic magmatic rocks in orogenic belts well inboard of plate margins during mineralisation (Thompson and Newberry, 2000). Granite emplacement typically has an orogenic to post-orogenic timing, with pegmatite belts emplaced ...

Mineral-deposit model for lithium-cesium-tantalum pegmatites

Lithium-cesium-tantalum (LCT) pegmatites comprise a compositionally defined subset of granitic pegmatites. The major minerals are quartz, potassium feldspar, albite, and muscovite; typical accessory minerals include biotite, garnet, tourmaline, and apatite. The principal lithium ore minerals are spodumene, petalite, and lepidolite; cesium mostly comes from pollucite; and tantalum mostly comes ...

Precambrian

Precambrian - Precambrian - Greenstones and granites: Greenstone-granite belts such as those of the Archean continued to form in the Proterozoic, albeit in greatly reduced amounts. They are characterized by abundant volcanic rocks that include pillowed subaqueous basalt flows and subaerial and subaqueous volcaniclastic rocks. Magnesian komatiites are for the most part absent, however.

Can You Find Gold in Granite? – Prospectingplanet

Indeed, while gold deposits have been found in the past in the quartz components of granite, the rock boasts a too-polished surface to act as an effective gold trap. Alternatively, formations such as irregular bedrocks and crevices, as well as minerals like quartz, can be more useful in identifying gold deposits and eventual pay streaks.

Porphyry copper deposit

Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magmatic ...
