Markasite: A Sparkly Ore with Diverse Applications

Introduction

Markasite, a mineral composed of iron disulfide (FeS2), has captivated humans for centuries with its captivating golden hue and striking crystal formations. Known for its versatility and diverse applications, markasite is making a resurgence in various industries, including jewelry, medicine, and energy storage. This article explores the fascinating world of markasite, unveiling its properties, applications, and potential for future advancements.

Properties of Markasite

Markasite is a brittle mineral with a hardness of 6-6.5 on the Mohs scale. It exhibits a characteristic cubic orthorhombic crystal structure, resulting in its distinct radiating or stalactitic formations. The mineral's golden-yellow to pale bronze color originates from its high iron content. Markasite is often mistaken for pyrite (fool's gold) due to their similar appearance, but it can be distinguished by its paler color and weaker magnetic properties.
