Galena rocks.

Pb isotopic compositions of the Korsnäs galena plot with the rest of the galena from Svecofennian supracrustal rocks studied by Vaasjoki (1981). Taken together, these data strongly suggest the carbonate is derived from crustal sources, probably hydrothermal in origin, and is not a carbonatite, sensu stricto (Mitchell, 2005).Aug 29, 2022 · Galena is primarily known for its lead content, but in rare cases, it also contains a considerable amount of silver. Among collectors, galena is best known for its sharp crystal system and its affinity for other minerals. Galena can be found alongside fluorite, calcite, and even pyrite. The combination of galena and pyrite is particularly ... Most of the minerals of Earth's crust formed through the cooling of molten rock (magma or lava). Molten rock is very hot, typically on the order of 1000 °C (1800 °F) or more. Heat is energy and temperature is a measure of that energy. Heat causes atoms to vibrate and temperature measures the intensity of the vibration.Galena is formed in hydrothermal veins in metamorphic or igneous rocks at moderate to low temperatures. Additionally, it produces solitary grains, dolostone and limestone substitutes, veins, and breccia cement in the form of sedimentary rocks. Fluorite, sphalerite, and calcite are only a few gangue minerals closely related to galena ore.

Galena is by far the greatest ore of lead. The extraction process to remove the lead from the sulfur is very simple, thus lead has been extracted from Galena since the earliest times. Galena from certain regions is rich in silver, and some specimens may contain as much as 20 percent silver. Because of this, silver-rich Galena is also an ore of silver. . Another use of Galena was its importance ...
