Regional metamorphism is most common in orogenic areas. True (ch10 pg 295) Tensional (or extensional) stress causes faults? Normal ( Tensional (or extensional) stress, stress that stretches or pulls apart the crust, causes normal faults)ch9 pg 256 The San Andreas Fault is a_____ fault. right-lateral strike-slip (ch9 pg263) Rocks that are metamorphosed at temperatures and pressures higher than 400°C and 400MPa respectively are known as _____ metamorphic rocks High-grade (ch10 pg282) The mineralogical, structural, textural, and chemical changes that occur below the area of sedimentation and diagenesis are known as _______. metamorphism (ch10 pg294 burial metamorphism) According to the figure below, _____ is the temperature at which melting starts. Seriously, this is not a trick question... look at the diagram. If you get this wrong just quit school because life is not going to be easy for you. According to the figure below, what metamorphic facies occur at 200ºC and 200 MPa. Again, this is not a trick question... look at the diagram. If you get this wrong just quit school because life is not going to be easy for you. The diagram below shows a(n) _____or a(n) _____ fault. Figure 9.10 on p.250 Amphibolite and greenschistfacies are most commonly associated with subduction zones. False _______ is the metamorphic process by which the chemical composition of the rock is changed by the addition or removal of fluids. Metasomatism (ch10 pg297) An igneous intrusion is commonly surrounded by a zone, or _____, of contact metamorphism. aureole (ch10 pg 294) A particular type of stress in which the forces acting on a body are the same in all directions is known as _____.
