Slate Slate Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called "slaty cleavage". It is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation, with a specialized tool in the quarry, many slates
Theory of change of change’ actually means; in some cases, what some program developers describe as a Theory of Change is, in essence, simply log frame, strategic plan or another approach that does not encompass the complexity of the theory of change approach. Practitioners have developed logic models and logical frameworks as strategies and tools to plan and evaluate social change programs. While these models well articulate the goals and resources of an initiative or organization, they give less focus to the complex social, economic, political and institutional processes that underlie social and societal change. Thus, while logic models and logframes have developed
