该项目是继发现在巴布亚新几内亚(PNG)东端附近的岛屿上有非常年轻的超高压岩石之后的又一发现。 一个主要目标是利用对该地区的详细研究,以更好地了解超高压岩石如何从很深的地方到达地表。 由于这些岩石位于构造活动区,因此可以认为,有很好的机会改进超高压折返模型,因为这个例子仍然处于其构造背景中。 有证据表明,这一进程正在进行。 与此相关的是研究该地区的整体构造演化,这是为了帮助了解超高压岩石是如何到达它们所在的位置以及它们来自何处所需要的。在这个框架内,该项目涉及一系列研究,这些研究有助于将超高压折返历史和构造演化拼凑在一起。 一项大型研究涉及被动地震数据采集,以便对可能出现部分折返的高压/超高压岩石的区域下方的地壳和地幔进行成像;大部分研究涉及岩石学、地质学、矿物物理学和地球化学。 此外,还包括全球定位系统工作和地球动力学建模。
英文摘要
The project is a follow-on to the discovery that there are very young UHP rocks exposed on islands near the eastern tip of Papua New Guinea (PNG). A major objective is to use detailed study of this area to better understand how UHP rocks get to the surface from great depth. Because the rocks are in a tectonically active region, it can be argued that there is a good chance of improving models for UHP exhumation because this example is still in its tectonic context. There is evidence that the process is ongoing. Related to this objective is the study of the overall tectonic evolution of this area, which is needed in order to help understand how the UHP rocks got where they are and from whence they came.Within this framework, this project involves a range of studies that can contribute to piecing together the UHP exhumation history and the tectonic evolution. One large study involves passive seismic data acquisition to image the crust and mantle beneath the area where partially exhumed HP/UHP rocks may occur at depth; a large fraction of the studies involve petrology, geology, mineral physics and geochemistry. In addition, GPS work and geodynamic modeling are included.
