Tanlu fault is an important intense deformation zone whose influence is great.It experienced multiphase tectonic evolution, and its quality is different during each period. Owing to its important geologic significance, it attracted a lot of scholars at home and abroad to research it.All the conginitions about Tanlu fault of each scholar are not identical.For understanding the developments better of Tanlu fault zone, we arranged and analyzed abundant research data of predecessor, and summarized its distribution characteristics, structural style, deep geological setting, formation and evolution, formation model and so on, and discussed the problems in the research.
