lavacicles
Posted: Nov 21, 2006 2:45 pm
Hey all,
I have a question about lava tubes-
I believe the standard explanation for lavacicles is that they formed when the lava was still molten, dripping...etc. etc...
I'm wondering if some drippy-looking formations in lava tubes could actually be calcareous but through mineral leaching/dyeing actually appear to be of the same igneous rock as the cave(tube) itself...this wouldn't explain the differences in their structure and form but then again why do we rarely ever see calcite formations in lava tubes anyway??
thanks
