Chapenite
Chapenite is a nodular fine grained brecciated jasper from Ft. Irwin, in the Mojave Desert, California, south of Barstow.
Brecciated Jasper means the jasper has broken or fragmented patterns. The term “brecciated” refers to the rock formation process where angular fragments of minerals are cemented together by a fine-grained matrix. Brecciated Jasper usually has a mixture of colors, including red, brown, beige, pink and sometimes yellow, with lines or splotches of other minerals interspersed throughout. These colors are a result of the minerals present at the time of.
Chapenite (sometimes spelled Chapinite) is a jasper that formed in a prehistoric ocean or lake bed millions of years ago and then was broken up by seismic shaking (earthquakes) from within the former marine sedimentary deposits. Then, as lots of time passed, the silica laden waters infiltrated the cracks and “healed” them, making the stone whole again and creating interesting colors and striking patterns within the stone.
Chapenite was named after Howard Chapin, who first recognized this material.
Though it is considered a jasper, Chapenite can also contain agate, it may have translucent areas or even pockets with druse agate crystals! Some people refer to it as a jasp-agate.
This area is on a military base and has been closed to collecting for a long time, making material of good quality very rare.
