Principles of Structural Analysis of Migmatites,l complexity of migmatites and other rocks affected by multiple deformation stems largely from a failure to adopt a systematic, sequential approach to the study. Presumably this is because, having initially been overawed by the complexity of the structure, the observer has forgotten, or has not appr

Development of Migmatite Structure: Overprinting, where overprinting (Sander’s ‘Uberpragung’, 1911) has taken place, the structural features that are overprinted are earlier than those that overprint them. This rule, fundamental in geology, has as its counterpart in stratigraphy, the ‘Law’, or ‘.’ enunciated by William Smith (1789-1839) and based

No doubt it is this initial sense of overwhelming complexity, particularly when experienced by an observer with little experience of such complex structures, that has prompted the use of expressions such as ‘wild

Field Approach: Reconnaissance and Detailed Study, consider what is entailed when it comes to putting the theory into practice and discuss aspects that are especially relevant to fieldwork in highly deformed rocks. In the following chapters we will examine examples from complex terranes that have been studied in detail using this approach.
