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

该项目涉及在印度尼西亚东部使用全球定位系统（GPS），这是一个广泛变形的地区，澳大利亚和东南亚的大陆边缘以及太平洋和菲律宾海的大洋板块正以每年80至110毫米的速度融合在一起。板块构造概念不能解释印度尼西亚和其他漫漫性变形带的演化，除非非常普遍，因为变形并不局限于明确的刚性板块的边缘。因此，对印度尼西亚和类似地方的研究对于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认识至关重要。印度尼西亚东部正处于大陆和海洋地壳元素的组合阶段，最终将形成一个复杂的山带。这种变形区域内的应变场是一阶观测，可以约束关于地壳和上地幔在造山过程中的行为的想法。

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.
