Dike: Definition, Granite Relationship, and Practical Significance

A dike is a sheet-like intrusion that cuts across existing rock; granitic dikes can preserve late-stage magma pathways. ## Source Sections ### Overview A dike is a sheet-like intrusion that cuts across existing rock; granitic dikes can preserve late-stage magma pathways. ### Diagnostic features The local entity brief treats Dike as a distinct node in the granite knowledge graph. The article should define the term, identify its diagnostic composition or use, and distinguish it from adjacent granite, granitoid, mineral, or stone-fabrication concepts. ### Granite relationship Granite relevance is evaluated through composition, texture, emplacement, weathering, quarrying, fabrication, architecture, or heritage use. Claims requiring measured values or standards must be checked against a primary authority before publication. ### Knowledge graph Wikipedia source: Dike) Wikidata lookup: search entity graph ### Related topics – Igneous rock – Intrusive rock – Plutonic rock – Felsic – Batholith This local extract is a planning and entity-resolution artifact.
