摘要
前陆是指与造山带相毗连的构造相对稳定地区,造山带的岩石向着它俯冲或掩覆,可分为三种类型,即曾为被动型大陆边缘的(Ⅰ型)、曾与沟－弧系有关的(Ⅱ型)和陆内造山带前方的(Ⅲ型)。前陆盆地为沿造山带前陆区分布的线状压性深坳陷,可分为周缘前陆盆地、弧后前陆盆地和陆内前陆盆地三种类型。前陆盆地系统是一个沿造山带分布的长条状的潜在沉积可容空间,可划分为楔顶、前渊、前隆和隆后等４个部分。
The origin and evolution of the concepts, foreland, foreland basin and foreland basin system, are reviewed. Foreland is a relatively stable area near compressive mountain ranges which can be divided into three types, type - I , used to be passive continental margins, type-II ,associated with drench- arc systems and type- III, related to intra- continental mountain belts. A foreland basin can be defined as an elongate, deep depression along convergent mountain. Foreland basins can be classified as peripheral, retroarc and intra-continen-tal(or reactive) foreland basins. A foreland basin system is a system of basins developing along a convergent mountain, which can be divided into wedge top,foredeep,forebulge and back -bulge in a cross section.
