The heat and fluids which feed hot springs are driven by subsurface volcanic activity. These types of systems are long lived and last from tens of thousands to upwards of millions of years. Recurrent magmatic pulses take place at depth, old conduits reopen and old hot springs regenerate at surface. Chemistry of upwelling fluids may change as they mix with ground water. The water table may change with the climate. Fluids may precipitate their dissolved iron, manganese or other materials along with silica. When an old hot spring gains new life, old cracks, veins and fissures below become conduits for new fluids. These fluids may deposit iron and silica and later seal the old cracks as the system cools down and dies again. These late crack fillings stained by the residual iron or other elements contrast with the older parent agate exhibiting a criss-cross pattern (pull-apart).

Hot spring deposits and their feeder systems can be later exposed at surface by uplift and erosion. The pebble size agates we find in modern day stream beds with red (iron) stained silica cemented (sealed) desiccation cracks are actually the fossil remains of ancient hot spring systems.

The different color agate which fills the healed cracks are just evidence of different mineral saturation in the late stage fluids pulsing the mature hot spring system.
