What does pegmatite dikes mean?

I believe in the context of geology a "dike" is a place where rock type has intruded into another rock type, often as magma seeping into cracks in older rock and hardening. So a pegmatite dike would be an intrusion of pegmatite into some other type of rock. --Delirium 19:41 15 Jul 2003 (UTC)
Ok, thanks. I just found the definition on dictionary.com which I hadn't noticed before. dave 17:02 16 Jul 2003 (UTC)

Can someone help me out with the geological definition of dike at dike? Extend it to a dike (geology) page if you like... Thanks. dave 17:18 16 Jul 2003 (UTC)

Done - or at least started. Dike (geology) --Vsmith 03:16, 11 Sep 2004 (UTC)

[edit] Etymology of "feldspar"

Funnily enough, on the German Wikipedia page for Feldspar the first part of the word Feldspat "feld" is explained to have its origin in the Swedish language with "fjäll" meaning hill, mountain. I'm also not so sure about your explaination for "spat" as well. I think I heard that its origin might be German ("spalten") with the meaning cleavable. Alex, Austria

I'm not sure about the Swedish terms either, Alex. The Swedish "fjäll" means (fish)scales or shingles, not mountain. The word "spat" does not seem to exist in Swedish language (online translation only, I'm not native). Its closeness to "spalten", the German word for "to cleave" is apparent (but maybe wrong...). But I seem to remember such etymology from college. "to cleave" in Swedish is "klyva". The etymological explanation as it is now (Mar 2008):
"Feldspar is derived from the German Feld, field, and Spat, a rock that does not contain ore."
thus feldspar = "rock without ore from the field", is probably wrong. feldspar = "cleaves like fishscales" would make more sense to me. But I'm not knowledgeable enough to change anything. --83.77.134.53 (talk) 00:39, 5 March 2008 (UTC)

[edit] Images

Please can someone give an idea of size, such as a scale bar. This is very basic stuff. Not including these is bad practice and makes the images of very little value.

[edit] Output map

This looks wrong. Each circle is said to represent a % of the top producer. The top producer is given as one country (Italy) but a number of circles of given for single countries (for example 9 in China) Surely the map should be based on countries aolone, or individual companies alone. The present design is a mess.

I have answered here. Best regards Rhanyeia 12:28, 16 August 2007 (UTC)

[edit] Text on map

Could some explain what "This map is consistent with incomplete set of data too as long as the top producer is known" actually means? As it is presently written it is jibberish. For example if it is acknowledged there is an incomplete set of data then it would be better not have anything - remember no data is preferable to bad data. —The preceding unsigned comment was added by 81.153.30.48 (talk) 05:57, August 23, 2007 (UTC)

I agree. It does not make a great deal of sense to me. Also data should not be published if it is incomplete. —Preceding unsigned comment added by 81.157.127.176 (talk) 21:51, 23 September 2007 (UTC)
