Novaculite: Description, Characteristics, and Other FAQs

In this article, you’ll obtain answers to common questions about Novaculite.

What Is Novaculite?

Novaculite is a type of sedimentary rock that’s composed mainly of microcrystalline quartz.

It is also sometimes called silica stone.

How Is Novaculite Formed?

Novaculite is formed in a marine environment when silica-rich sediment is deposited on the seafloor.

The sediments undergoes diagenesis, or burial metamorphism, which changes the sediment into rock.

How Long Does It Take For Novaculite To Form?

The time it takes for Novaculite to form; it depends on the rate of sediment deposition and the depth at which burial metamorphism occurs.

It takes millions of years for Novaculite to form.

What Does Novaculite Look Like?

Novaculite can vary in color. It can be white, gray, black, or even green.

The rock is usually fine-grained and has a waxy or greasy luster.
