Jaspers are found world round. There are many localized names but jasper is universal. Agate is too. Lake Superior agate is characterized by iron and the vivid reds, many blue agates are from the american west. They are also found worldwide. Trace elements cause color variations. There are tube agates, fortication agates, dendritic agates, .... they are actually banded chalcedony. I will attempt to get a name for your type of jasper. Read up on agate and jasper formation to understand the similarities and differences. If your rock has agate formation under 50 percent it is not considered "officially" an agate.Lastly some natural things like wood in a petrified forest can become agatized. The silica replaces natural fibers in the wood. All very interesting. Short discussion on differences below.
