Druse

[FairieSpirit]

Okay all you rock hounds.....here are two different definitions for Druse

Geological Glossary: Druse
A crystal-coated surface of rock, commonly used interchangeably (but erroneously) with vug.


(geology) drüz
A small cavity in a rock or vein encrusted with aggregates of crystals of the same minerals which commonly constitute the enclosing rock.

in reference to the second definition...what is the difference between a geode and druz...is the geode crust not the same as the crystal cavity????

they seem like different definitions....first one.. crystal-coated surface
second... small cavity

this is confusing me............
and what is a window druse????:weirdsmil

i cannot refer to english definitions, but in germany, a geode can be any mineral compound, but druse mostly refers to amethyst, very rarely to clear crystal

vugs are similar to geodes. actually geodes are a form of vug. but that is debate.

let's see a geode is a rough sphere like minerial that could be the size of ping pong to the size of a polar bear. it's lined with a thin layer of chaledony with a cavity that is filled with another minerial. the most commonly known is quartz, of course there are other minerials that could be found in it as well. Unlike a druse, a geode is separable by weathering as a discrete concretion from the minerial in which it occurs and its inner minerials are not of the same minerals as those of the enclosing minerial. druse are of the same minerials. also duses may contain water in them.
