In petrography, triple junctions are a part of a suite of textures collectively called "granoblastic texture" resulting from metamorphic recrystallization of a rock. Three grains will often meet at a triple junction, with three 120 degree angles defining the intersection. This is also called "foam texture". Perhaps this should be included, along with a link to the "granoblastic" page. -A university instructor of 3rd and 4th year geology. —Preceding unsigned comment added by 205.206.125.33 (talk) 20:46, 17 February 2009 (UTC)


Please note that "triple junction" also refers to a well known type of thin-film solar cell that uses three layers of silicon as opposed to the more common two layers. This makes for higher efficiencies. This technology is expected to become commonplace in the near future. http://sharp-world.com/corporate/news/070124.html

Okay - things to add:

Stability criteria (eg. RRR always stable, FFF never stable etc.) Movement of triple junctions. Examples from Earth

How about an example? Ravedave 00:39, 16 July 2005 (UTC)

I don't, yet, know the best way to put it but we are going to have to be careful with the stability criteria (from kinematics - e.g. RRR is always stable) and our observations of the Earth (RRR triple junctions can form in the early stage of rifting, but then one of the arms stops spreading, the Bay of Biscay is just one example).

add from wiki mid ocean ridge[edit]

24.50.151.151 (talk) 12:13, 3 October 2014 (UTC) I do not now have the link but one (of many) ocean trench pages revealed the massive Indus delta off the coast of India, so large it spread over the triple junction. There was talk of deleting that page as duplicating info which I asked them not to.
