Check out the pattern on this Jackson crossroads site 4 crystal. What could have caused this?  |

I thought the same thing, Ryan. "Ancient Aliens" will be calling soon to film it!!

What is XL crystal growth?

XL is shorthand for crystal

I concur. Definitely Alien Shorthand!  Cool pic, AG. Thanks for posting. Joe |

I'm pretty sure it's contact from other crystals that crystal face was against. The striations you see on the surface are a feature of quartz on quartz contact. There's the slight possibility that it was another mineral that caused the pattern but I believe it was quartz.

There's the slight possibility that it was another mineral that caused the pattern but I believe it was quartz. It for sure wasnt quartz. These were in a pocket with 200 or more crystals and were a single layer of crystals pointing upward as a cluster /vug lining in a managanese pocket. There was not any quartz contacting the terminations and quartz doesnt dissolve easily ( meaning it is unlikely that there were quartz crystals in the pocket contacting the terminations which later dissolved away). |

Hey Rodney,
Do you still think it was growth interference by some other mineral that has eroded away? Have you seen this in other crystal pockets and think that maybe it could have been some environmental conditions during crystal growth that caused this? (ie.. variations in solution temps or flow rates, etc)
What's your guess?
Mickey

we have found a few that looked to be interference growth lines from a mineral that has dissolved away, but this one is different from those. I honestly dont have a clue!

Looks to me to be new re-nucleation sites that occurred after the first (larger) xtal grew. The subsequent multiple crystals grew across the face of the larger xtal and ran into each other, then started growing out and over. Pretty common in artificially grown crystals, since multiple small crystals are energetically favored over single larger xtals. John L. |
