MANGANOTYCHITE Meaning and
Definition
-
Manganotychite is a mineral that belongs to the arsenate family. It typically appears as compact and granular masses with a dark brown to black color. The mineral was first discovered in the 19th century and was named after its composition, which includes manganese (Mn) and the Greek word "tyche," meaning luck or fortune.
In terms of its chemical composition, manganotychite is classified as a manganese arsenate mineral. It has the chemical formula MnAsO4·H2O, indicating that it consists of manganese, arsenic, oxygen, and water molecules. Manganese is a transition metal, while arsenic is a metalloid known for its toxicity.
Manganotychite is generally found in hydrothermal deposits or areas where manganese ores have been altered by secondary processes. It commonly occurs in association with other manganese minerals, such as pyrolusite and rhodochrosite. It is also often found alongside arsenic-rich minerals like scorodite and pharmacosiderite.
The mineral has a distinct metallic luster and a dark brown to black streak. Its hardness is relatively low, ranging from 2 to 3 on the Mohs scale. Manganotychite is also known for its brittle nature and uneven fracture.
Due to its scarcity and limited practical use, manganotychite is primarily of interest to mineral collectors and researchers studying the geochemistry of manganese and arsenic minerals. Its unique composition and presence in various geological environments contribute to our understanding of mineral formation and evolution in Earth's crust.
Etymology of MANGANOTYCHITE
The word "manganotychite" is a mineral name derived from two components - "mangan" and "tychite".
The term "mangan" refers to manganese, a chemical element that is commonly abbreviated as "Mn" on the periodic table. Manganese gets its name from the Latin word "magnes", which means "magnet". This is because manganese compounds were initially discovered in a region called Magnesia, known for its magnetic properties.
The second part of the word, "tychite", refers to an obsolete mineral name that comes from the Greek word "tyche", meaning "fortune" or "chance". It was named so because the mineral occurred by chance in a particular location or due to certain circumstances.
Combining these two components, "manganotychite" essentially means a mineral containing manganese elements that forms by chance or in specific circumstances.
