0 Geological Maps 1: Horizontal and Inclined Strata A well-rounded geologist must be familiar with the processes that shape the Earth as well as the rocks and minerals that comprise it. These processes cover the entire spectrum of geology from sedimentation, through rock deformation, to mountain building . This is all very different from the material that you covered in the first portion of GY 111 (e.g., rocks and minerals), but don't panic. Many students find rock deformation and mountain building to be the most fascinating areas of geology. Rock deformation is defined as all changes that occur to the volume and/or shape of a rock body . As you will learn in the lecture portion of GY 111, rock deformation is a component of structural geology . The lectures will mostly be dedicated to the theoretical aspects of rock deformation, structural geology and mountain building. The labs will be dedicated to teaching you how to recognize and interpret the consequences of rock deformation and structural geology. They include tilted and overturned strata, folds and faults. At this point, a warning is called for. In the first portion of GY 111, you were responsible for learning the properties that characterize rocks and minerals. This was largely a self-regulating process. You worked at your own pace and were in the lab at times that best suited your schedule. Clever students did most of their learning during the lab sessions. Others (you know who you are!), did it the night before exams.

Geological Maps: Horizontal and Inclined Strata 1 Cramming for the rocks and minerals section of this course might have actually worked for you, but if you try the same for the geological map component of GY 111, you will surely fail. Structural geology and ultimately the interpretation of geological maps requires a significant amount of background knowledge. It is our job to teach this to you and we do it a little bit at a time to ensure that your brains do not explode. However, if you do not keep up with the work, you will be in over your head in no time. The lab exercises at the end of each chapter will help you to learn the concepts necessary to survive structural geology and each subsequent series of exercises builds upon the previous ones. Make sure that you do each set of lab exercises when instructed to, and be prepared to turn them in for assessment at the beginning of the next lab period . As already implied, it is a good idea to get as much of the lab done as possible in your assigned lab period. In this way, you will be able to ask questions in the lab when there are one or more instructors available for help. Geological maps are not all that difficult, but they do commonly cause problems for students because they involve three-dimensional configurations of rock layers (or strata) and a whole lot of geological information. This chapter of the lab manual contains useful information about rock types, geological time, map symbols and other related information that you will need to interpret geological structures (e.g., folds and faults)
