南极半岛中生代岩浆弧具有长期的右行走滑变形历史。这种变形最初与广泛的增生杂岩的发展有关，通过弧前碎屑的迁移，以及厚的弧前盆地序列的形成和反转。它也是弧内主要剪切带内的重要组成部分，并可能控制了弧后地区沉积盆地的形成。尽管弧前区的一些横流运动与斜向俯冲有关，但主要运动发生在冈瓦瓦兰岛解体和形成主要的伸展裂谷系统期间。考虑到这一横流运动，提出了冈瓦瓦兰这一部分的新重建。
The Antarctic Peninsula Mesozoic magmatic arc has had a long history of dextral, strike-slip deformation. The deformation was initially associated with the development of a wide accretionary complex, by the migration of fore-arc slivers, and the formation and inversion of a thick fore-arc basin succession. It also formed an important component within major shear zones in the arc, and may have controlled the formation of sedimentary basins in the back-arc region. Although some transcurrent motion within the fore-arc region was related to a component of oblique subduction, the main movement occurred during the breakup of Gondwanaland and the formation of a major transtensional rift system. A new reconstruction for this part of Gondwanaland is presented taking this transcurrent motion into consideration.
