Agates form as cavities in rocks are exposed to silica rich water over time that has percolated through. So how does something like this fun horizontal banding form? Well, it percolated up into the rock from the bottom and did so long enough for agate banding to form that way. Details like this give us interesting tidbits about how our dynamic planet functions! #agate #sciencetok

Banded jasper beach agates form through a fascinating process that unfolds over time. 🌊 Initially, silica-rich fluids permeate cavities in rocks along the shoreline. These fluids deposit layers of chalcedony—a type of microcrystalline quartz—creating the banded patterns within the agate. 🏞️ The constant movement of the water further polishes and refines the agates, giving them their smooth, beach-worn appearance. Each agate becomes a natural masterpiece, capturing the essence of geological art
