Texas, the "Lone Star State"

Gypsum "Ram's Horn"
Crystal Cave, lower levels, (like, maybe the 300 level) Mariposa Mine, California Hill, Terlingua Mercury District, Brewster County, Texas, USA

To start the mineralogy of the Lone Star State we used the image of this fine Gypsum from Gail Spann.
Thanks Gail! |

Here is an important part of the mineralogy of Texas.
I thought this would be a good start, with more photos of minerals and localities to come.

I can only wish this was in my collection. This is in the Paris School of Mines just has you walk through the front door. The label is about 2in high. This was a wow factor since this has to be one of the best Selenites/Gypsum for the location. Photo is mine.

Here is another ramshorn selenite on matrix, from a different locality. This one grew inside a concretion. This photo was taken the first night I had my then new dSLR. Still learning macro technique, so I apologize for the busy background. This came from a very large concretion.....a lot of specimens were recovered.......but only two good ones. The other selenite was hand sized, but not as curved. We flipped a coin, and I got first choice.
Pfeil Mine, Karnes Uranium District, Karnes County, Texas.

Here are some more minerals from Texas. They are all self-collected. i went to school in Canyon, Texas and El Paso Texas, worked for Pioneer Nuclear and was Noranda's Texas Projects Geologist. Hence the opportunities to collect these minerals. All of these specimens are from the Terlingua Mercury District and nearby environs.
Next I will post some odd-balls from the Lone Star State y'all (thanks Gail).

The Terlingua Mercury District is characterized by breccia pipes, collapse breccias that formed just a big jumble of limestone boulders. Caves are not uncommon in the mines of the district. Lots of open cavities means good collecting. |

This tiny crystal is 1.8 cm long. Montroydite is perfectly sectile normal to the c-axis. It is so flexible that the crystals can be bent, and even tied into knots. There are old texts that illustrate this. Had to throw in a rarity. I have a suite of the oxychlorides of mercury, but they are very difficult to photograph, and to be truthful, kind of boring unless you are a species collector. Miguel Romero got my best Gianellaite, the finest in the world. Wonder where that specimen wound up?. |

I cannot say words.
Paul, cool pics from Texas, including flowers and child.
Ed, my mind remains twisted like your gypsums. Please, go on. What can I say about the vertebrae fitting? Although 1967/1967 could sound near to prehistory for young minsurfers I am afraid -not my case-, so you had some advantage (I am kidding, of course).
Cheers

Ed-
Thanks for the great calcites and gypsums!!! I graduated from Canyon High School and spent MANY days hiking through Palo Duro Canyon. Was aware of the celestine but never found any. I do have some calcites from there, however, as well as phytosaur vertebrea and teeth.
Thanks again for posting!

Ah. So Darren, we have some common ground. I found the 1st half of the vertebra on my senior year picnic from Caprock High School there in Amarillo. The second half was on our 1st field trip for Historical Geology at WTSU there in Canyon. I found only one tooth, either Phytosaur or Buetnerria, not sure which. The celestite was a pleasant surprise.
Thanks for your click-back.

Antonio, you silver-tongued devil. Thank you for your words of appreciation. I am honored by your reply. I posted the specimens from Texas because the crystals are unusual and beautiful, and were collected BEFORE I had ever attended the Tucson show.(1975, first time to go there). To my knowledge, the location in the Chinati Mountains is the only known occurrence of wulfenite in Texas. So, pretty cool, eh?
Thanks again for the input. Wait till we do Mississippi.
Gratefully yours,
Ed

My tongue is fairly dull in English, you all are lucky for that :-) However I admire your sportmanship.
Very cool indeed your rare pieces from Texas. Texas alone has the same area as Spain or so.
Then, I am looking forward to seeing Mississipi trip.
Kind regards

Ed-
Spent my youthful days skateboarding all over Caprock, and trying to climb that big orange monster (Auditorium?) - never made it! We lived on Browning Street before my parents divorced and I moved to my dad's place in Timbercreek Canyon. My maternal grandparents lived on Nelson Street, just behind the church - 1 street over from Caprock! I remember trying to jump a skateboard down those outdoor concrete steps at Caprock. My mom graduated from there i about '65. Small world, huh????

Great posts, and great stories! Thanks for sharing! That Phytosaur fossil find was inspiring- to come back to the same location, and find the other half... It is true skill. Bravo!
Thank you for posting the pics, and the effort to find them and share them.
