Common error in many major, online professional geological references... claims that metamorphic rock "protoliths" are only sedimentary and igneous rocks. |

Wikipedia "Metamorphic Rock" article correctly states that metamorphic rock "protoliths" include "... and existing metamorphic rocks." This sentence lacks a major professional geological reference, so I provided one above. More available. |

Proven cases over billions of years of plate tectonics show many major mountain belts have undergone multiple orogenies (mountain [re]building events) that clearly include re-metamorphism. Sometimes more intense "prograde" [re]metamorphism; sometime less intense "retrograde" [re]metamorphism.

I moved back the setence about metamorphism to metamorphism, ie, undoing redirect, because i intend to write a proper article about that.
What is missing? Facies and textures. Muriel Gottrop 15:14, 1 Aug 2003 (UTC)
Though well-written I rated this article only "B" for the "WikiProject Geology" assessment because of the severe lack of references. The only reference (apart from a few external links) is to the 1910-11 public domain version of Encyclopedia Britannica; I think the science of metamorphic geology might have moved on just a little since then. --Zamphuor 15:35, 22 April 2007 (UTC)[reply]

The reference to 150 degrees C should be checked. That's only 302 degrees F. That doesn't sound right.69.122.62.231 (talk) 23:20, 11 February 2008 (UTC)[reply]
Thank you for that.69.122.62.231 (talk) 16:59, 15 February 2008 (UTC)[reply]
Hey, what about this idea of the mica or phyllosilicates realigning themselves mechanically within metamorphic rock. I bet it is way more complicated than that. Reference Please! Has any experimental geologist done this in a lab? In addition, styolites caused from pressure solution are very common in marble can be argued as an erratic foliation since they can be composed of carbon, iron oxide, or phyllosilicates. This is based on field experience within several Nevada mines. Here is the only link I could find on the subject. http://erictwelker.com/pressuresolution.htm I am too busy to research this for the next year. — Preceding unsigned comment added by 108.64.107.80 (talk) 21:45, 3 July 2014 (UTC)

Hello fellow Wikipedians,
I have just added archive links to one external link on Metamorphic rock. Please take a moment to review my edit. If necessary, add {{cbignore}}
after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}}
to keep me off the page altogether. I made the following changes:

Hi, im requesting to make temporary changes to this petrology page for a college exam. I need to increase the information regarding the "mixing and minlging" of rocks. basically I need to add 3-4 pages of information regarding that subject. There is literally no information regarding this topic on wikipedia at all. thanks!

basalt is metamorophic and is a rock 51.37.43.200 (talk) 07:25, 26 November 2019 (UTC)[reply]
I know in the more traditional sense of types of metamorphism, it is mainly regional versus contact (or "local"). However, I do think at least a mention of shock metamorphism is relevant. There's even a Wikipedia page that could be linked/mentioned: https://en.wikipedia.org/wiki/Shock_metamorphism It includes many things like impactites, high-pressure polymorphs of quartz like coesite. I think Sudbury or Ries are a prime examples. Joedf (talk) 18:25, 19 February 2020 (UTC)[reply]
