Jasper is a form of chert with impurities and inclusions. For example, an Fe impurity will cause for the red-coloured Jasper, Cu will cause for blue, Ni for green, etc. Chert is an extremely hard, microcrystalline form of quartz. It is typically formed by the accumulation of silicious skeletons of marine creatures (e.g. diatoms and radiolarians; form in beds of chert) or by chemical replacement (i.e. migration of silica) of nodules in carbonates. Jasper is typically in association with the later, for if formation occurs as a nodule in an iron-rich dolostone, fluids that migrate the silica will also cause for the iron to relocate, causing the impurity upon precipitation.
Jasper forms through the deposition and solidification of silica-rich fluids or volcanic ash in cracks and cavities within rocks. These fluids then slowly crystallize over time, creating the banded patterns and vibrant colors that jasper is known for.
Jasper a Intrusive rock is an intrusive rock which is opaque. It is a variety of silica which is impure.
Jasper House is located approximately 31 kilometers (19 miles) south of the town of Jasper in Alberta, Canada.
Jasper is a naturally occurring form of chert, a variety of quartz, which owes it's red or orange coloring to impurities of iron.
