This morning I put together a collection of drawings the Geode Kid made.  |

 So how did this one form the way it did? 7x 5 inches. Good possibility that it is a Lucky Strike mine egg. Bought it form a gentleman at a small rock show in Burns Oregon a few years back. He said he was from Prineville, Oregon. |

He said he was from Prineville, Oregon. Very Interesting! The upper left corner appears to be the main entry point after the steam condensed and the void became vacuum chamber, sucking in nearby shattered rock that collected primarily in the lower right corner, becoming less common toward the entry point. The shattered rock particles became nucleating places for the first crystal growth - Opposite from the fig-1 below because instead of the liquid being experimentally supersaturated, crystallization was driving it from f to a, from poly crystals to single crystals.  later flooding sequences first eroded, then filled in the remaining spaces. Harder to understand is the repeated rectangular areas! Perhaps calcite or feldspar plates that were later replaced with agate? A delight to ponder! |

Thank you so much Dave! I figured a brighter mind would prevail!  I don't think it is a coconut. Not enough calcite. I'm not sure where it came from. The iron stain seems to be where the water table usually was for a long period. Well, darn it all...I thought we had it figured out. LOL |

1dave , just for the sake of clarity, you define Amygdala as"geodes. But I've found agates with no interior cavity that formed in almond shapes in vesicular basalt. Does the term relate to a single shape of vesicle or material contained in all shapes (non-almond shapes included?) Precious opal is found in basaltic vesicles at the Whangdoodle Mine in western Idaho as well as other locations. They're not always almond-shaped. Would they be called amygdules as well or is there a more appropriate name? Not to my knowledge. Science is as Science does. They form as gas bubbles. What do gas bubbles do? Some form as teardrops, spheres, flat bottoms, collect in bunches, . . . Smooth exteriors in basalt, but as the silica content increases with melting the overhead crust rocks, basalt magma changes to andesite, becoming lumpier. The bubbles have to conform. Whoever named them was probably a man studying the brain. en.wikipedia.org/wiki/Amygdule It occurs to me... since many "orbicular jaspers" are technically rhyolite (OJ and leopardskin for sure, possibly even some/all PJs), I guess the orbs are also technically miniature thundereggs, still in matrix. |

That's the first time I've seen the interior without it being cut. That's really neat! I wish I could contribute more pics, but I've only got three examples of Thundereggs...two slabs and one half of one. So, I'll have to settle for ogling for the time being! |

I especially love the Blue Bed t-eggs. That one makes me think of the view looking out of an ice cave at the sea. Wow! Thanks for showing that beauty off, woodman . Did some cleaning up today on the patio, and accidentally found a triple egg. I remember that it was a raffle prize when we used to belong to a club, and actually went to meetings! It is a half piece, not face polished. But the price was right. Yeah, I know, pictures or it don't exist. Will try to take some tomorrow. |

You have no idea how difficult this little task was for me, what with me having CRS and all. I had seen this triple T-egg while looking through my rock stash for something else. It was in a place it should not have been, but I was excited to see it. Even remembered where I had gotten it from.
So I mentioned it in the post just above on 1/7/21, which was a Thunderegg Thursday. I went out with my camera a couple days later, with the intention of taking a few pics of it, and I couldn't find the darn thing! Should not have been that difficult to find it, I mean, it's not like it could have sprouted legs and walked away... It had been in a smaller cardboard box, wrapped in brown paper, somewhere in the mess that is under my patio table.
Looked for it some more the next day, no luck. Finally I saw something on top of the table. Something wrapped in a beige colored plastic bag. Eureka, I had found it!
But wait, the story is not done yet. It was too late in the day for natural light to take the pics, so move another day forward to today. Took my camera out, and again, could not figure out what I had done with it. Just a little searching today, and it found it, on the table still. But not in a box, and no longer wrapped up in a beige plastic bag. Without further ado, I got some pics of it, and present them here, for your enjoyment.
A nice triple t-egg. 
Area to the left side.
Love the mossy/filament stuff to the right side in this center egg. 
And lastly, the lumpy outside of it. Should have taken one more shot of it from the side. Oh, well. 
I was going to wait until Thursday to post the photos, but figure you all have waited long enough. Not only that, but I wanted to get them posted to the forum before I misplaced the images, lol.
I keep telling my husband that I am losing it... 
(I think he is starting to believe me.)

Ahhh...another person afflicted with CRS syndrome. Don't think you're the only one afflicted with this issue. What were we talking about? Oh, that right...squirrels! That left side of the egg(s) is mesmerizing! I keep going back to the picture to look at it! Thanks for going through all the headache to post these pics! |

I have the joy of finding stuff that I cut years ago and have no memory of it at all. JUst like finding it in the first place!! Nice triple! Thanks, Bob. What you said about rediscovering rocks you had cut and forgotten all about reminded me of a joke about Alzheimer's patients. Something about meeting new friends every day. Ten years ago, it would have been funny, but not so much now. My dad is 90, I go visit him every Monday, and do whatever he has put on my "do" list - yard work, watering, cut his toenails, talk with him, etc. He has good days and not so good days. I wouldn't say he has Alzheimer's, or even dementia, but some days, his thought processes work a little slow. Some days, like yesterday, he can talk about things that happened 80 years ago like it was last week. Other days, he's a little "foggy." His father also lived into his 90s. He was healthy as a horse, but his mind slipped. I know this is what I have to look forward to. He has a neighbor across the street that is in her 80s. She is showing signs of dementia, and sometimes slips out of the house and wanders some. (Her daughter needs to have her people watch her more closely.) She came over to talk to me while I was raking leaves in the front yard, and showed me her pill caddy, and was asking me which ones she should take next? OMG, she needs more supervision! What she said next, about broke my heart. She said, "BTW, my name is Lucy." I have known the woman - and she me - for years. Sad. We know we are all heading down that road, some faster than others. |

I do what I can, especially after I've said I would do it. I don't just have CRS, I've also got ADD. Only it's not squirrels, it's chickens that distract, lol. ![]()  Lol. |

That triple egg is very cool! I love the pattern on the left side. But the difference between the eggs is even more interesting. It’s like having hard boiled eggs with a side of scrambled eggs all in one! |

It’s like having hard boiled eggs with a side of scrambled eggs all in one! So much to teach us! When did they expand? when and where did they fill? When and how did they become triplets? [/quote] |
