Stable parts of continental crust just sit there for billions of years, doing nothing. In the oceans things are much more dynamic. Live fast, die young, stay pretty is the motto of oceanic crust. It goes on one of the most amazing journeys rock can take. Along the way it affects well nigh everything in and on the planet. Lets tag along. Making the crust. Mantle material, usually made of a dark heavy rock called peridotite, is odd stuff. Whenever Ive seen it on the surface it always looks out of place somehow, too homogeneous, too brown, too massive. Yet it forms over 8. Found everywhere immediately below the crust, from between 5 to 7. C hot enough so that it flows slowly to us, but fast on geological timescales but still remains solid. The top, lithospheric, layer of mantle has frozen on to the crust, becoming part of a rigid plate. The rest makes up the aesthenosphere, where the mantle is constantly flowing and mixing, like hot soup in a saucepan. Our little piece of oceanic crust is about to be formed at a mid ocean ridge, where two plates move apart. This makes space that is filled by part of the hot mantle rising up whereupon the reduction in pressure causes it to melt. Rock is made up lots of different minerals and when it melts it usually doesnt melt completely and produces a magma that has a different composition than the original rock. Shallow melting of mantle material gives basaltic magma. This rises up and pools into magma chambers. Here it may cool to form coarse gabbro, or flow upwards through cracks to form basalt lava flows, or cool in the cracks to form a sheeted dyke complex. This creates a characteristic layered pattern in the crust. Pillow basalts. Image from Earthwatcher on Flickr. N0. 02. 88. 27. 65. All of this is taking place under water. A 2. 5 km thick pile of water in fact. When magma reaches the surface, it flows out as lava but it cools extremely quickly and forms piles of distinctive pillow shapes. Water also flows down into the crust where it is heated up. When it comes back to the surface, at places called hydrothermal vents, it may form dramatic chimneys called black smokers, built up as minerals precipitate out of the suddenly cooled brine. Water is making important changes under the surface, changing the original igneous minerals into new ones, often by putting H2. O into the mineral structure. Incredibly, it seems there may be bacteria living in this hot wet rock deep below the surface. That sinking feeling. As our new crust slowly drifts at finger nail speed 5 cmyr away from the ridge, it cools and grows denser, causing the sea bed to sink. Sediment builds up on top. We are a long way from land and the sediment tends to consist of dead things with great names falling from above diatomaceous ooze, globigerina ooze, the Titanic. It depends. After 5. Ma million years our crust is denser than the underlying mantle. It would sink down into it, but it is part of a rigid plate so it cant until it reaches a subduction zone, that is. Subduction zones, usually associated with deep ocean trenches, are found around the world. They are doorways a place where our crust leaves the surface and enters the interior of our planet. As it moves down into the subduction zone, our crust is pushed down under another plate. It bends down and starts to sink into the mantle the older the crust, the steeper the angle. Some of the sedimentary cover is scraped off, to form an accretionary wedge above the plate. All this scraping and bending is associated with earthquakes, some of the strongest ones known. The bending of the plate allows water to get into the mantle part of the plate, further changing its composition. Subduction zones and mid ocean ridges are linked. In them, creation and destruction is broadly balanced. Oceanic crust is created from the mantle and returns there to be destroyed. The balance is not perfect 0ceanic crust starts of different in composition from the mantle and all that brine it interacted with caused many chemical changes. The crust returns changed and cant just turn back into peridotite it stays as something more interesting. As our crust starts to sink deeper into the subduction zone, the pressure increases. A lot. Imagine the pressure of a kilometre of rock sitting on top of you I bet you cant. For every kilometre the crust descends, the more rock is pressing down on it. The temperature increases too, but to a lesser extent the cold crust takes a long time to heat up. As conditions change, two things start to happen, metamorphism and metasomatism. Firstly the minerals forming the basaltic rock such as plagioclase, pyroxene, olivine become unstable and new minerals are formed metamorphism. This process is fairly continuous as the conditions change, but the most dramatic and attractive transformation occurs about 2 million years after subduction starts, at around 5. Here the basaltic rock turns into eclogite. Eclogite with rutile. Photo from Graeme Churchard. N0. 06. 08. 20. 84. Many of the metamorphic reactions affecting the crust release water which flows from the subducting crust up into the wedge of mantle sitting above it. Water is a fantastic solvent, so it takes other elements up dissolved with it this flow of material is called metasomatism. These elements tend to be ones that make large ions, like Potassium and Boron they are harder to fit into the increasingly tightly packed mineral structures that form at depth. Its as if they are being squeezed out of the rock. How on earth does a slab of rock force its way deep into the earth The driving force is density. Old cold subducting crust starts off denser than the surrounding rock and the process of turning it into eclogite makes it 1. Over geological timescales the mantle behaves like a stiff fluid and a cold and rigid dense plate is able to force its way into it. The force generated by the sinking plate is called slab pull and is one of the major drivers of plate tectonics. Eclogites make the worlds plates go round. After burial, rebirth. A lot of what we know about subducting crust comes from pieces of it that have somehow got back to the surface. We dont know of any eclogite that has been deeper that 1. One such method is to study the pattern of earthquakes associated with modern subduction zones. Over time, plotting their distribution picks out the subducting plate and shows that typically it carries moving down to at least 6. One, rather important, consequence of subduction is the creation of volcanic arcs. These are chains of volcanoes, parallel with the subduction zone, typically about 1. Many major modern day volcanoes, such as Mount St. Helens and Krakatoa are found in volcanic arcs. Subduction zone diagram from infringer. Flickr http www. N0. Working out what is going on below volcanic arcs relies on the indirect tools provided by geochemistry studying the composition of earth materials. We know the composition of what we start with subducting crust and mantle materials and of what we end up with volcanic rocks and comparing the two gives insights into the process. Its complex. At depths of 1. The resulting magma, along with the water mentioned earlier, rises up into the wedge of mantle above. This rising material then lowers the melting point of the hot mantle wedge, so in turn parts of that melt. This new mantle wedge melt is what rises to the surface and forms the volcanic arc.
