Collaborative Research: Establishment of a Geodetic Crustal Dynamics Network in Eastern Indonesia Using the Global Positioning System

该项目涉及在印度尼西亚东部使用全球定位系统(GPS)，这是一个变形很大的地区，澳大利亚和东南亚的大陆边缘以及太平洋和菲律宾海的海洋板块正以每年80至110毫米的速度汇合在一起。板块构造概念无法解释印度尼西亚和其他扩散变形带的演化，除非非常笼统地解释，因为变形并不局限于定义明确的刚性板块的边缘。因此，对印度尼西亚和类似地区的研究将对发展更普遍的全球构造理论和扩大我们对板块相互作用动力学的知识至关重要。印度尼西亚东部正处于大陆和海洋地壳元素的组装阶段，最终将形成一条复杂的山脉带。这种变形区域内的应变场是一级观测，可以限制人们对造山过程中地壳和上地幔行为的看法。

This project involves using the Global Positioning System (GPS) in eastern Indonesia, a region of broad deformation where the continental margins of Australia and Southeast Asia and the oceanic plates of the Pacific and Philippine Sea are coming together at rates of 80 to 110 mm/yr. Plate tectonic concepts do not explain the evolution of Indonesia and other diffusely deforming belts except very generally because deformation is not confined to the edges of well-defined, rigid plates. Hence, the study of Indonesia and places like it will be critical in developing more general theories of global tectonics and expanding our knowledge of the dynamics of plate interactions. Eastern Indonesia is at the stage of assembly of the crustal elements, both continental and oceanic, that will eventually form a complex mountain belt. The strain field within such deforming regions is a first-order observation that can constrain ideas about the behavior of the crust and upper mantle in mountain building.
