-
The mineral contains essential elements like sodium, calcium, magnesium, iron, silicon, and aluminum.
-
It crystallizes in the monoclinic system, which means its crystal lattice is shaped like a skewed rectangle.
-
Magnesiohastingsite's structure includes double chains of silica tetrahedra, a characteristic feature of amphiboles.
-
The presence of hydroxyl groups (OH) in its structure contributes to its classification as an amphibole.
Physical Properties
Magnesiohastingsite's physical properties make it identifiable and useful in various geological studies. Let's explore these properties.
-
It has a Mohs hardness of 5 to 6, making it relatively hard but not as hard as quartz.
-
The mineral exhibits two directions of perfect cleavage, which means it breaks along specific planes.
-
Its specific gravity ranges from 3.0 to 3.5, indicating it is denser than many common minerals.
-
Magnesiohastingsite is typically opaque, meaning light does not pass through it.
-
It has a vitreous to dull luster, giving it a shiny or slightly matte appearance.
Occurrence and Locations
Where magnesiohastingsite is found can tell us a lot about the geological processes that form it. Here are some notable occurrences.
-
It is commonly found in metamorphic rocks such as schists and gneisses.
-
Significant deposits of magnesiohastingsite have been discovered in regions like the Alps, Norway, and the United States.
-
The mineral often occurs alongside other amphiboles, feldspars, and quartz.
-
In igneous rocks, it can be found in gabbros and basalts, which are rich in magnesium and iron.
-
Magnesiohastingsite is also present in some skarn deposits, which form through the interaction of magma with carbonate rocks.
Uses and Applications
While not as widely known as some other minerals, magnesiohastingsite has its own set of uses and applications.
-
It is used in geological studies to understand the conditions under which certain rocks form.
-
The mineral can help in identifying the metamorphic history of a region.
-
Magnesiohastingsite's presence in igneous rocks can provide clues about the magma's composition and evolution.
-
It is sometimes used as a gemstone, although this is rare due to its dark color and opacity.
-
Collectors and museums value magnesiohastingsite specimens for their scientific and aesthetic appeal.
