LINDGRENITE Meaning and
Definition
-
Lindgrenite is a mineral that belongs to the copper-arsenic-antimony sulfide family. It is typically found in hydrothermal ore deposits and is named after the Swedish-American geologist, Waldemar Lindgren.
The chemical composition of lindgrenite can vary slightly, but it is generally composed of copper (Cu), arsenic (As), and antimony (Sb). It has a chemical formula of Cu 3(AsO4)(AsO3OH)(OH)2. Lindgrenite forms in low-temperature environments where sulfur-rich fluids interact with copper-rich rocks, often in association with other copper minerals.
Physically, lindgrenite usually occurs as small crystals or as grains in compact masses. It commonly appears as earthy, powdery, or botryoidal aggregates. The mineral can exhibit colors ranging from greenish-blue to turquoise, and it displays a vitreous to dull luster when polished.
Lindgrenite is not a widely known or economically important mineral. However, its presence can provide valuable clues for geologists in mineral exploration and ore prospecting. Its distinctive crystal structure and specific chemical composition can help identify the geological processes that have occurred in a particular area and provide insights into the formation of associated copper deposits.
Overall, the unique properties and occurrence of lindgrenite make it an interesting mineral for study and mineralogical analysis in various scientific fields, including geology, mining, and mineralogy.
Etymology of LINDGRENITE
The word "lindgrenite" is named after Waldemar F. Lindgren (1860–1939), a Swedish-born American geologist who made significant contributions to the field of economic geology. He is particularly known for his work on ore deposits and his studies on the formation of mineral resources. Due to his contributions to the field, a mineral was named after him, and it was given the name "lindgrenite" in his honor. Lindgrenite is a rare copper arsenate mineral that was first identified in the Shield's (Lode) Mine in Arizona, USA.
