Unformatted text preview: 1 Lab 12 High Pressure Metamorphic Rocks from Saih Hatat, Oman (mostly mafics) In this section, you will examine samples that represent a progressive metamorphic sequence from Region III, Saih Hatat, NE Oman (Fig. 2). For this lab, all you have to do is examine the samples carefully, determine the mineral assemblage and the important textures for each sample and answer the questions . You should then try to construct a paragenetic sequence diagram for these mafic rocks. III-207 This sample was collected from the lowest grade zone A of Region III (see Fig. 2). 1- List the mineral assemblage of this sample? 2- What is the Ti-bearing mineral in this sample? 3- When do you think the epidote formed in this sample (relative to the other minerals and to the prevailing deformation)? Support your answer with labeled illustrations. 4- Represent the mineral assemblage of this sample on an ACF diagram 2 As-101: This sample was collected from the same mafic unit from which III-207 was collected, but from zone B (Fig. 2). but from zone B (Fig....
