Tectono-Thermal Evolution and Exhumation in Transpressional Orogens: the Deep Crust of the Damara Orogen

许多现代板块边界涉及构造板块之间以高度倾斜的角度会聚。这些斜向会聚的系统产生了跨压造山带，在那里断层和岩石变形是垂直于板块边界的缩短和平行于边界的剪切的组合发生的。在转压造山带中，岩包通常显示出与中央走滑断裂带相邻的高度可变的压力-温度-时间路径。该项目的重点是确定考古带地壳深部岩石的变形和折返历史，考古带是南比亚省约5亿年的达梅拉造山带的北支。考古带是典型的挤压造山带，剥蚀程度较深，因此可以在地表评价中、下地壳的岩石变形过程和热历史。Kaoko带的运动学和热学史使我们能够深入了解沿着现代挤压系统发生的构造过程，如加利福尼亚州的圣安德烈亚斯断层和新西兰的阿尔卑斯断层。

Many modern plate boundaries involve convergence between the tectonic plates at highly oblique angles. These obliquely convergent systems produce transpressional orogenic belts where faulting and rock deformation occurs by a combination of shortening perpendicular to the plate boundary and shear parallel to the boundary. In transpressional orogens, rock packages typically show highly variable pressure-temperature-time paths adjacent to a central strike-slip fault zone. This project is focused on the determining the deformation and exhumation histories of deep crustal rocks in the Kaoko zone, which is the northern branch of the ca. 500 million year old Damera Orogen in Nambia. The Kaoko zone is a classic transpressional orogen that is deeply eroded so that the rock deformation processes and thermal histories of the lower and middle crust can be assessed at the surface. The kinematic and thermal history of the Kaoko zone gives insights into the tectonic processes occurring at depth along modern transpressional systems like the San Andreas Fault, California and the Alpine Fault in New Zealand.
