1 ERSC 4011 El-Shazly, A. K., 1996 Outcrops of the Ophiolite Suite along route 23 In this field trip we will examine the different rock types of the Semail ophiolite exposed along route 23. The main objective of this field trip is to train you to recognize the differences between the various parts of the ophiolite so that you can map areas with similar outcrops easily. Other objectives include training you to identify different rock types, intrusive relations and the petrogenetic significance of field and textural relations. Write a short (2 - 3 page - long) essay on the Semail ophiolite summarizing your observations. Stop 1: 7 km SE of Sinsilah: The rocks exposed in this stop belong to the mantle sequence. 1- How many rock types can you identify in this area? Name these rocks listing the essential mineralogy of each. 2- What are the age relationships between these rock types (i.e. arrange these rocks from oldest to youngest). What led you to these conclusions? Draw a labelled diagram of the field relations that led you to this conclusion.
