Improving Mindat.orgUploading rock photos results in mineral species error message

3rd Mar 2017 19:32 UTCKelly Nash 🌟 Expert

Guessing this may have been mentioned before - I uploaded a rock picture (lamproite) a few minutes ago, just to see how it works (now that rocks can be uploaded with minerals). I was pleased to see that lamproite was in dropdown menu for rocks, but after uploading, I got the familiar message on the photo caption "the mineral species Lamproite is not listed in our database...". I wonder if there is not a way to distinguish between mineral species and rock types in the error message so that future users are not confused wondering what mineral lamproite is. In this case, I'll go back and try to edit the locality to add lamproite as a rock type for the locality (with a suitable reference), but I suspect this problem will occur again and again until the locality database is as populated with rocks as it is with minerals.

On a related note, there's a locale in Missouri where devonite (www.mindat.org/min-6565.html) is found. I've been thinking about adding the locale to Mindat, but since there aren't any individual minerals found there I may just add a photo or two to the devonite page. Any thoughts?

Curiously, the devonite page indicates its an informal name for a porphyritic dolerite, but also gives a formula for a hydrous aluminum phosphate!

Devonite is also a synonym for wavellite. Another rock and mineral that have the same name.

If you have a rock photo, please add the locality and post it there.

I've posted photos of two specimens to the devonite page, and just used the general "Fredericktown District, Madison Co., Missouri, USA" as the locale. The photos are pending approval, but here's one of them:

It seems unreasonable to me that an igneous intrusive rock, and associated minerals, that has nothing to do with the classic lead mining region around Fredericktown, Missouri, should be included as a sub locality of that mining district. Can't Mount Devon, and also Rhodes Mountain and Robinson Mountain, be noted as geographic sites in Madison County, without being included within the old mining district ?

Tom,

All mining/mine sites have one or more host rock units. It can be very helpful to have images in the locality page for the various rock units not just the ore body.

What would make this a whole lot easier is a way to designate those host rock units and download them without running foul of the mineral species lists.

So having a specific drop down selection category to choose them might solve this issue.

Tom,

You're right on with Mount Devon as being the exact locale where my devonite is from. Maybe I should have just used "Madison County" as the locale, but I was trying to give a little more info without creating a new locality page.

Steve, that's fine to have an interest in "host rocks", but I don't think these particular intrusives have anything at all to do with the lead mineralization. The ore host rock is generally limestone. These intrusives just happen to be in the same county.

Kevin, adding Mount Devon as a new site would be the best idea, generally the more specific we make our locations the better.

Devonite now seems to have been separated into two pages thanks Dave. Though porphyrytic dolerite would be what most geologists would call this specimen, but that's not listed. And the devonite page now lacks the links to the rock hierarchy. I changed its status from a variety to a rock type as I imagine the former only applies to minerals?

????

I did it. Devonite should be fixed once I do a new import from the sheet.
