What This Document Is
These are lecture records from Earth History (GY 112) at the University of South Alabama, prepared by Dr. D. Haywick in 2006. The material focuses on foundational concepts in geology, specifically a detailed review of rock types and the rock cycle, with a strong emphasis on sedimentary rocks and their significance in understanding Earth’s past. It appears to be designed to complement textbook readings and prior coursework (specifically GY 111).
Why This Document Matters
This resource is ideal for students currently enrolled in or planning to take an introductory Earth History course. It’s particularly valuable for those needing a refresher on basic rock classifications before diving into more complex topics like stratigraphy, paleontology, and geological time. Students who benefit from detailed lecture notes and visual aids will find this especially helpful for reinforcing concepts presented in class and preparing for assessments. It’s best used *in conjunction* with assigned readings and lab exercises.
Common Limitations or Challenges
These lecture records are a supplement to, not a replacement for, active class participation and assigned course materials. The notes are specific to Dr. Haywick’s 2006 lectures and may reflect a particular teaching style or emphasis. While comprehensive in its overview, it does not offer practical application exercises or detailed field study guidance. Access to the full document is required to gain the complete understanding of the concepts presented.
What This Document Provides
* A recap of the three primary rock classifications: igneous, sedimentary, and metamorphic.
* An overview of the parameters used to classify sedimentary rocks, including grain size and composition.
* Categorization of sedimentary rocks into clastic, bioclastic, chemical, and organic types.
* Key terminology related to sedimentology and rock identification (e.g., lithification, fossiliferous).
* References to relevant textbook chapters for further study.
* A summary chart referencing materials from a prior course (GY 111) for context.
