In this article, you’ll obtain answers to common questions about mariposite.
What Is Mariposite?
Mariposite is a metamorphic rock, well known for its shiny and reflective surface.
It is also commonly referred to as “rainforest marble” or “birdseye rhyolite.”
What Is The Composition Of Mariposite?
It’s made up of chromium-rich green micas known as glauconite.
Mariposite often contains quartz, feldspar, and other minerals.
It can be found in shades of yellow, green, white, or gray.
The color is usually caused by the presence of iron.

How Is Mariposite Formed?
Mariposite is usually found in metamorphic terrains that have undergone low-grade regional metamorphism.
Mariposite can also form from the alteration of chromite-bearing rocks in a hydrothermal environment.
What Does Mariposite Look Like?
Mariposite has a glassy to pearly luster and a vitreous to dull fracture.
It’s usually found as an enclave in metamorphic rocks.
