14.7.3: Aragonite Group Minerals
Aragonite 's softness ( H = 3.5 to 4), color, and association help identify it. Like calcite, it effervesces in cold dilute HCl. However, it does not have well-developed rhombohedral cleavage like calcite. If not well crystallized or showing orthorhombic cleavage, it may be difficult to distinguish from calcite.

Aragonite | Mineralogy4Kids
Aragonite. A member of the aragonite group of minerals, Aragonite is a low-temperature, near surface mineral that forms speleothemes in caves, massive lamellar deposits by geysers and hot springs, as seafloor oolites and as a replacement mineral. It was named in 1797 for the type locality, Molina de Aragon, Spain.

1. Introduction. Aragonite is the most abundant mineral in modern-day, shallow-marine carbonate sediments (Gischler et al., 2013) and has been for a large proportion of the Phanerozoic Eon (Hashim and Kaczmarek, 2019).Because aragonite is a metastable phase under most Earth surface conditions, aragonitic sediments tend to …

Blue Aragonite vs Caribbean Calcite
There's this cool thing called the Mohs scale, and it's like a ruler for mineral hardness. It goes from 1 (super soft) all the way up to 10 (super hard). Both blue aragonite and Caribbean calcite fall near the bottom of this scale. Blue aragonite is around 3.5 to 4, while Caribbean calcite is close by at 3 to 3.5.

Calcite vs. Aragonite: What's the Difference?
Aragonite's main use is in jewelry, and due to its relative instability, it's less common in industrial applications. 12. Aragonite is thermodynamically less stable than calcite at standard temperature and pressure and can transform into calcite over geological time scales. Calcite remains stable under a broader range of environmental conditions.
