(Granite, Gabbro, Diorite) 2 of 16 Pluton Large, irregular shaped mass of igneous intrusive rock 3 of 16 Dyke/Sill Sheet-like body of intrusive igneous rock. 4 of 16 Igneous (Extrusive) Solidify fom lava that has erupted to the earth surface. If successive eruptions occur, this may from sheets. 5 of 16 Sedimentary Rocks Formed at the earth surface from the deposition of precipitates of dissolved solids/organic matter, which froms into hard rock. 6 of 16 Detritus Precipitates of solids/organic matter. 7 of 16 Strata Sedimentary rock layers 8 of 16 Conformable Neatly stacked strata that have no time gap between them 9 of 16 Unconformity Break in a sequience of rocks that represet a period of non-deposition or erosion. 10 of 16 Angular Unconformity Younger beds overly & truncate older beds which have been folded or tilter, 11 of 16 Disoconformity both younger and older strata lay parallel to eachother, yet there is an abrupt change in age across the disconformity. 12 of 16 Nonconformity Stratified sedimentary rock overlay older plutonic igneous or massive metamorphic rocks 13 of 16 Metamorphic Rocks Rocks that have undergone a transformation as they have ben subjected to high temperatures, pressures &/or fluids. 14 of 16 Foliation Layering 15 of 16 Contact Metamorphism occurs when hot malten magma "bakes" the surrounding rocks 16 of 16
