The photograph below shows two fracture faces. One is vertical (N30W\/90) and bears a plume, and the other has an intermediate dip (N76W\/42SW).<\/p>\r\n

Given this image, answer the following questions.<\/p>\r\n

a) What type of fracture is the vertical fracture? What is the orientation of the principal stresses and the tectonic regime that produced it?<\/p>\r\n

b) What is the mode of formation of the N76W\/42SW fracture? What is the orientation of the principal stresses and the tectonic regime that generated it?<\/p>\r\n

c) Is it possible that both fractures could have been formed in the same tectonic event (same stress field)? Explain your answer.<\/p>\r\n
