For those seeking introductory resources in Structural Geology and Optical Mineralogy, several key textbooks are recommended. "Optical Mineralogy" by David Shelley is noted as a solid choice, particularly for its relevance in university geology programs. Another significant recommendation is "Optical Mineralogy" by Paul Kerr, which, despite being based on older editions, remains valuable for understanding polarized light in minerals. Additionally, "The Manual of Mineral Science" by Cornelis Klein and Barbara Dutrow is highlighted as a required text for mineralogy courses, offering useful insights that extend into petrology studies. These resources are considered essential for foundational knowledge in the field.
