Porphyroblast vs Porphyroclast

I remember being told there was a difference, so I put back the braces that Vsmith removed. Woodwalker 22:32, 7 June 2006 (UTC)[reply]

No problem, seems I misread in the edit screen and thought that was a second linking of porphyroblast. There is a bunch of red there though :-) Vsmith 22:53, 7 June 2006 (UTC)[reply]

Tectonite

All mylonites are tectonites but schists, gneisses and other ductiley deformed rocks with a strongly developed fabric are tectonites as well; actually most mylonites are L-S tectonites. So I guess I have to write an article. Mikenorton 20:50, 7 November 2006 (UTC)[reply]

Sinistral/Dextral

Clockwise and anticlockwise depend on which direction you are viewing the rock. Clockwise is only dextral if you are looking down at a steeply-dipping mylonite with a near horizontal lineation. Mikenorton 19:53, 6 March 2007 (UTC)[reply]

Metamorphic Rock?

"Mylonite" is a structural term on its own is a structural term. It is meaningless (aside from describing the structure) to use to name a rock unless you also attach the original rock name (if you can determine it). For example, a quartzite having undergone deformation to a mylonite would be called a quartzitic mylonite. Alison Troup —Preceding comment was added at 07:37, 24 May 2008 (UTC)[reply]
