Caledonian Movement in southeastern oft-com:office:smarttags" />Guizhou area has a significant affect on the deposition pattern, magmatism, deformation and metamorphism, and it leads to unconformity contact between the Late Paleozoic strata and underlying strata. Luocheng-Longsheng in Guangxi and Tongdao region in Hunan are high-position tectonic areas of Caledonian Movement, which appears on a regular change westwards to eastern Guizhou area in the plane with underlying strata respectively Sinian, Cambrian, Ordovician and Silurian; after Caledonian Movement, the deposition of the Early Devonian is featured by lack of sediments in the high-position tectonic area, namely erosion zone, while in east and west sides of high-position tectonic area it appears Early Devonian sedimentation, namely depression area; contact interface is characterized by high-angle unconformit, low-angle unconformity and parallel unconformity; degree of deformation and metamorphism gradually weakens, and metamorphic degree of early Paleozoic strata decreases from obvious to not obvious, thus from a close Alpine-style folds to the open-type Alpine folds. oft-com:office:office" />
