Chapinite is a nodular jasper that was fractured and then resealed with agate or chalcedony turning it into a brecciated jasper.
It was found originally on the Fort Irwin Military base by a guy named - I think - Roy Chapin. Later it was found at Siam Siding which is off Route 66. Another deposit was uncovered by Castle Butte west of Barstow.
All this is Mojave Desert region.

Great looking pieces, thanks Lowell. Looks like they polish into great looking cabs.

Another deposit was uncovered by Castle Butte west of Barstow. All this is Mojave Desert region. A buddy of mine was on an assignment around the Fort Irwin area over the weekend.......He was with a couple of casual rock hounds and ran across some material that looked interesting........he thought of me and brought back several fist size pieces of stuff and dropped them off late last night........Asked me to look into it and cut some up tumbling size for him and to keep the rest.
I did not take any pictures of the rough material, but some of it looked like a cross between a Jasper/Agate mix, although not much crystallization, very sharp and translucent.......the rest of it was a Jasper for sure.
Went in early to work this morning for a couple of hours, came home and started research......found this thread.......looked up Barstow locations and the area fits. Did a couple of acid tests, ran it under my long wave UV (it glows a yellow pea green) and has speckles of blue/white seams.
Started scubing and cutting up.....posted picks of the pieces (wet)........any opinions on both the Agate and Jasper are more than welcome....!
Top 2 rows all came off the same stone.
Third row and fourth row two different stones......need help identifying......

None of that is chapenite.
Pea green longwave means tiny tiny bit of uranium. Parts per million glow green.

Thanks NRG........I took another look (long wave) at the Agate tonight with my wife (she is not color blind, I am red & green).......she see's it as a orange/yellow almost the color of pineapple, as she calls it. It's not as bright like the pea green/yellow (wife confirmed) on two of the other Jaspers pieces that fluoresce within the surface fractures........sorry for the confusion.
So what do you believe the Agate is........and also the blue-ish (3rd row) and the greenish (4th row) Jasper....?
I ask my buddy again where he found the material, he thinks it was the Nelson Wash area since their project was about 1/2 mile away.......parcel survey to do with the Nelson Lake rehab extension.
I understand you're very knowledgeable with respect to the Mojave Desert area. Any information is appreciated.........thanks.

I am having a very hard time understanding why you are still using the attachment feature on this board. People have explained several times that it is a limited and very expensive feature, that is why almost everybody uses a third party to host there photos. I like the fact that you want to post many pictures but please respect the fact that there is a large cost involved in posting attachments.................................MrP |

pizzano Tapatalk is very easy to use Thanks Ali.......I'm using one of my go-to third party applications........getting to much flack here using RTH's attachment tool. Guess we're not suppose to take "advantage" of the service.....as if I post that many "image heavy" anyway........lol......I've gotten more responses to image transfers than I have rock identification help.........why offer it, if it's "to expensive" to support.........being called out as "disrespectful" doesn't set well either........(no reflection on you Ali). |

I am sure it is a reflection on me but that is OK. I have not seen anybody else on here that it has taken so long to take the HINT. I believe it is respectful to not use a service that cost RTH dollars once a person gets used to the board and starts posting a lot. You say you don't post 'image heavy' posts but I have found where you post 3 attachments one after another. I normally keep my mouth shut but seeing you keep on using the feature, after a number of people tried to 'suggest' you use another source, I decided to be more blunt. This is a wonderful board and I am sure many people want it to be around for a long time. As you know nothing is free. I know that Tommy says there is money in the pot but that is probably mainly because of donations and auctions. I think Tommy is running this because of his love for the hobby. The board would have to get very large before it would generate an income. I just feel it is being respectful to limit the cost involved in running the board. I will say no more....................MrP |

In the future mrP....please consider dropping me a PM if you have a beef about something I did or said here at RTH, rather than aggrandize your personal opinions publically here, without offering up any real help or useful contribution to the thread topic, wasting good web space........thank you for your consideration.
