The conception, studied objects and basic constituents of non-Smith strata are elaborated from theory level: Non-Smithian strata are the strata that have undergone mixing of different degrees, thus were deformed, metamorphosed and displaced into disorder totally or partially. They are the disorder parts in orogenic belts. Melange is the solo studied object of non- Smithian stratigraphy. The slices in melange is one of the basic constituents of non- Smithian strata, and also one of the basic units in the non-Smithian mapping. The slices used in this paper refer to blocks divided by small-scale tectonic boundaries and have certain constitutes. Superslices used in this paper refer to a set of slice association with similar tectonic deformation bounded by large-scale tectonic mixing.
