Plate tectonic features: find the following places on a world map, label your blank map with its number, determine the plate tectonic setting and features including (a) type of boundary, if any nearby, and approximate distance and direction from boundary, (b) physiographic features, (c) volcanism, (d) types of rocks being formed, and (e) earthquakes that occur. (see hefferan 7-18) plate tectonic setting and features for each region, choose all that apply from each letter below a) tvpe of boundary convergent (w/subduction zone extending into mantle, 100s of km under overriding plate), divergent (w/oceanic ridge system and nift valley), transform (w/transform fault). hot spot volcanic activity (not a type of boundary, may occur at or away from boundaries) lb) leconv.) oceanic trench, (over subduction zone mountain range with volcanic arc, or island arc of composite volcanoes, (div.) rift valley, mid- ocean ridge system, basalt plateaus (on land), @hot spots) shield volcanoes, (e trans fault trace, offset mountains or mid-ocean ridges c) volcanism and location relative to boundary: (over subd. zone, ie, not at boundary) explosive eruptions of rhyolitic pyroclastics, @div. & hot spots) fissure eruptions, basalt floods lif on land), shield volcanoes [if on land), mid-ocean ridges of pillow basalts (for submarine eruption) (d) types of rocks currently forming and where they are located relative to boundary over subduction zone (not at boundary): granitic (at depth), rhyolitic (volcanic),& metamorphic, divergent (and hot spots): basalltic (volcanic) e) earthquake characteristics lindicate position relative to boundary): (conv.) strong shallow along boundary, deep over subduction zone (div. and hot spots) shallow and mild to moderate, letrans) mod.-strong, shallow 1. mid-atlantic ridge from north of iceland to the southern atlantic (see tectonic map from lecture d. 2. iceland (see hefferan fig. 1.3 and tectonic map from lecture) b. 3. peru-chile & andes mountains (note: not at boundary but inland from oceanic trench) b.
