What is the formula of petzite?

It forms isometric crystals, and is usually associated with rare tellurium and gold minerals, often with silver, mercury, and copper. The name comes from chemist W….

Where is Petzite found?

Description: Petzite is a steel-gray granular mineral found in hydrothermal deposits associated with other rare tellurium, gold and silver minerals. TAYLOR COUNTY: Petzite is found as small grains intergrown with pyrite, chalcopyrite, calaverite, krennerite, and other minerals at the Bend Deposit, NW sec. 2 T. 32N.

What is gold’s fracture?

Fracture is jagged. Streak is golden yellow. Hardness is 2.5 – 3. Specific Gravity is 19.3+ (extremely heavy even for metallic minerals)

What is Ag in minerals?

Silver (Ag) has a bright, metallic luster, and when untarnished, has a white color. It is rarely found in its native form. Silver can be found combined with a number of different elements such as sulfur, arsenic, antimony or chlorine to form a variety of minerals and ores, such as argentite, chlorargyrite, and galena.

What is gold Telluride?

Calaverite or gold telluride is an uncommon telluride of gold mineral with chemical formula (AuTe2). It was discovered in Calaveras County, California, in 1861 and named for the county. The color ranges between brass-yellow and silvery-white with green to yellow-green streak and metallic luster.

What elements are mistaken gold?

Pyrite is called “Fool’s Gold” because it resembles gold to the untrained eye. While pyrite has a brass-yellow color and metallic luster similar to gold, pyrite is brittle and will break rather than bend as gold does. Gold leaves a yellow streak, while pyrite’s streak is brownish black.

Why is it called Telluride?

Our Mining History Most say Telluride is named after tellurium, a nonmetallic element associated with rich mineral deposits of gold and silver. Others say it originated from the castaway call “To-Hell-You-Ride” shouted by loved ones who knew of the town’s boisterousness.

How is quartz used in everyday life?

Today, billions of quartz crystals are used to make oscillators for watches, clocks, radios, televisions, electronic games, computers, cell phones, electronic meters, and GPS equipment. A wide variety of uses have also been developed for optical-grade quartz crystals.
