Geological Mapping Derain 10 Quadrangle

项目摘要

The four-year orbital mission of NASA's MESSENGER spacecraft ended in April 2015. In preparation for Europe's Mercury orbiter (BepiColombo), which will be launched in 2017, a co-ordinated effort is being mounted by the MESSENGER and BepiColombo teams to produce geological maps of the whole of Mercury using the best MESSENGER data available. The maps will provide very important contextual information for planning and interpreting BepiColombo data, and will replace the partial map coverage at 1:5M scale achieved using Mariner-10 data.Mercury is divided into 15 mapping 'quadrangles' (including one at each pole), and the student on this project will be responsible for creating a geological map of one of the southern hemisphere quadrangles under the guidance of the supervision team at 1:3M scale. This will be ether the south polar quadrangle (H-15 Bach) between 66 S and the pole, or one of the four quadrangles (H-11 to H-14) in the belt occupying 21-66 S. The choice will depend on mapping known to be already underway by colleagues at other institutions. However, every quadrangle has a wide range of features and a long and complex geological history making it an exciting region to study. It is particularly important to understand Mercury's southern hemisphere as fully as possible. This hemisphere was less-well studied by MESSENGER, but it will be observed in detail by BepiColombo and so southern hemisphere mapping will establish the context for what we expect to be BepiColombo's most novel findings.The student will compile a geological map in ArcGIS using MESSENGER narrow- and wide-angle-camera images supplemented by topographic and spectral data, all of which will be available from NASA's Planetary Data System (pds.nasa.gov), and will co-ordinate with colleagues mapping adjacent quadrangles. Mapping will follow United States Geological Survey protocols and conventions agreed among the joint MESSENGER-BepiColombo geological mapping team, and the map will be published via USGS. Online digital publication facilitates the inclusion of multiple layers, so that (for example) this new generation of maps could have a chronostratigraphic version (surface units divided by age, such as smooth plains, intercrater plains, and so on) and a more innovative lithostratigraphic version (for example subdividing plains into spectral types). Mercury is tectonically complex, and so the systems of isolated and linked faults will require careful attention.Although a thorough quadrangle map will be the main product of this study, the intimate insight gained by close examination of any part of Mercury will offer plenty of opportunities for spin-off science. These could, for example, be geomorphological, tectonic, related to space-weathering, or related to volatile processes, according to the student's interests. We would expect the student to present findings at meetings such as the annual Lunar & Planetary Science Conference (Houston) and the European Planetary Science Conference, and also to submit papers for publication in peer-reviewed journals. The supervisors will train the student in ArcGIS and planetary geological mapping, in addition to which there will be opportunities to attend MESSENGER-BepiColombo mapping workshops in Europe and/or the USA. Experience of geological mapping in Earth would be an advantage.

NASA MESSENGER 航天器为期四年的轨道任务于 2015 年 4 月结束。为了准备将于 2017 年发射的欧洲水星轨道飞行器 (BepiColombo)，MESSENGER 和 BepiColombo 团队正在协调努力，利用现有的最佳 MESSENGER 数据绘制整个水星的地质图。这些地图将为规划和解释 BepiColombo 数据提供非常重要的背景信息，并将取代使用 Mariner-10 数据实现的 1:5M 比例的部分地图覆盖。水星被分为 15 个测绘“四边形”（每个极点各一个），该项目的学生将负责在监督团队的指导下绘制南半球其中一个四边形的 1:3M 比例地质图。这将是南纬 66 度和极点之间的南极四边形（H-15 巴赫），或者是占据南纬 21-66 度的带中的四个四边形（H-11 至 H-14）之一。这一选择将取决于已知其他机构的同事已经在进行的测绘。然而，每个四边形都具有广泛的特征和悠久而复杂的地质历史，使其成为令人兴奋的研究区域。尽可能全面地了解水星的南半球尤为重要。 MESSENGER 对这个半球的研究还不够深入，但 BepiColombo 将对其进行详细观察，因此南半球测绘将为我们期望的 BepiColombo 最新颖的发现奠定基础。学生将使用 MESSENGER 窄角和广角相机图像并辅以地形和光谱数据，在 ArcGIS 中编制地质图，所有这些都可从 NASA 的行星数据系统获得 (pds.nasa.gov)，并将与同事协调绘制相邻四边形的地图。测绘将遵循 MESSENGER-BepiColombo 联合地质测绘小组商定的美国地质调查局协议和公约，地图将通过 USGS 发布。在线数字出版有助于包含多个图层，因此（例如）新一代地图可以具有年代地层版本（按年龄划分的表面单位，例如光滑平原、火山口平原等）和更具创新性的岩石地层版本（例如将平原细分为光谱类型）。水星的构造很复杂，因此需要仔细关注孤立和相连的断层系统。虽然完整的四边形地图将是这项研究的主要产品，但通过仔细检查水星任何部分所获得的深入见解将为衍生科学提供大量机会。例如，根据学生的兴趣，这些可能是地貌、构造、与空间风化有关或与挥发过程有关。我们希望学生能够在年度月球与行星科学会议（休斯顿）和欧洲行星科学会议等会议上展示研究结果，并提交论文以在同行评审的期刊上发表。导师将对学生进行 ArcGIS 和行星地质测绘方面的培训，此外，学生还将有机会参加在欧洲和/或美国举办的 MESSENGER-BepiColombo 测绘研讨会。有地球地质测绘经验者优先。
