摘要
黔西南地区燕山—喜山运动期间发生过4期褶皱,它们通过跨褶、移褶、限褶、重褶、弯转、加强等方式叠加,在区内形成穹—盆构造,蛇形褶皱、环状褶皱等复杂的露头干涉型式。叠加褶皱对金矿田具有重要的控制作用,多数矿田不仅受叠加褶皱形成的穹隆控制,而且大致按15～20km的等间距排列。本区叠加褶皱的深入研究,对基础地质、成矿规律研究及成矿预测等均具重要意义。
In the southwestern Guizhou sedimentary region, there exist complicated folds formed by superposition of four period folds. The major types of superposed folds are ridden fold, shifted fold, non sequent fold, bended fold, refolded fold and enhanced fold. Outcrop pattern of the superposed folds are dome structural, basin, winding folds and ring folds etc. The gold mine field is almost all related to with the superposed folds. NW-SE and NE-SW direction range and utensil equidistance are chiefly assumed to the dome structure. Its interval is roughly 15～20km. The research of superposed folds possesses has important significance to the basic geology, mineralization law and mineralization prognosis.
