Serpentinite
Serpentinite is a metamorphic rock primarily composed of the mineral serpentine, which forms from the alteration of ultramafic rocks like peridotite. It typically exhibits a greenish color and a smooth, waxy texture, making it visually distinctive. This rock is often found in areas where tectonic plates interact, particularly in regions with significant geological activity.
Serpentinite is important in geology because it can indicate the presence of subduction zones, where one tectonic plate moves under another. Additionally, it has been studied for its potential use in carbon capture and storage due to its ability to react with carbon dioxide, forming stable minerals.
