项目摘要
Understanding how melts are generated and focused across hundreds of kilometers through the upper mantle to the narrow mid-ocean ridge (MOR) axis is fundamental to understanding how Earth's ocean crust is formed and how elements and heat are exchanged between the interior of our planet and its surface. Significant advancements have been made in the use of computer models to investigate mantle melting and melt transport. However, the lack of complementary geophysical and geochemical data from the same area is a critical information gap that needs to be filled before progress can be made in refining present models. This research entails a multidisciplinary geophysical and geochemical program to map, sample, and analyze samples from the 8°20'N Seamount Chain that extends 200 km westward from the East Pacific Rise Siqueiros ridge-transform intersection in the Pacific Ocean. Seamounts provide a unique opportunity to test hypotheses of melt distribution and source variation that occur away from spreading centers. Melts that build these seamounts provide geochemical windows into the upper mantle. The research includes an oceanographic cruise to map and sample the targeted region. This will be followed by geophysical data processing and petrographic, petrologic, and geochemical analyses of samples collected by both using ALVIN, a manned deep submersible, and dredging. Goals of the research are to develop new, integrated models for upper lithosphere structure, deformation, and melt distribution at a fast-spreading center and investigate the dynamics of off-axis melting. The approach is interdisciplinary and includes analysis of geophysical and geochemical data and geodynamic modeling. Rock samples will be analyzed for all major and trace elements and radiogenic isotopes of Nd, Sr, and Pb will also be analyzed. Broader impacts of the project include creation of a marine geology curricular unit targeted at the middle school level and compliant with Next Generation Sciences Standards that have currently been adopted by 45 states. The project involves working closely with teachers and administrators of Pipkin Middle School, a nationally ranked Title I school that serves 580 students in the low-income center-city of Springfield, MO (poverty index of 78%). The teachers will work closely with the reserachers and both parties will jointly create the educational materials. Emphasis will be placed on inquiry learning and connecting fundamental science processes with current research. The pilot implementation will coincide with the proposed field program. The developed unit will be made broadly available via the web on curricular resource sites.
了解熔体如何产生并集中在数百公里范围内穿过上地幔到狭窄的大洋中脊 (MOR) 轴,对于了解地球洋壳如何形成以及元素和热量如何在地球内部与地壳之间交换至关重要。在使用计算机模型研究地幔熔化和熔体迁移方面已经取得了重大进展,但是,缺乏来自同一地区的补充地球物理和地球化学数据是一个关键的信息空白,需要在取得进展之前予以填补。制造于这项研究需要一个多学科的地球物理和地球化学项目来绘制、采样和分析北纬 8°20' 海山链的样本,该链从太平洋东太平洋海隆 Siqueiros 脊转换交叉点向西延伸 200 公里。海山提供了一个独特的机会来检验远离扩散中心的熔体分布和来源变化的假设,形成这些海山的熔体为了解上地幔提供了地球化学窗口。随后将对目标区域进行地球物理数据处理,并对使用载人深潜器 ALVIN 和疏浚采集的样本进行岩石学、岩石学和地球化学分析。该方法是跨学科的,包括对地球物理和地球化学数据以及地球动力学的分析。将对岩石样本的所有主要元素和微量元素以及 Nd、Sr 和 Pb 的放射性同位素进行分析,该项目的更广泛影响包括创建针对中学水平并符合标准的海洋地质课程单元。下一代科学标准目前已被 45 个州采用,该项目与皮普金中学 (Pipkin Middle School) 的教师和管理人员密切合作,该中学是一所全国排名第一的学校,为低收入中心城市的 580 名学生提供服务。密苏里州斯普林菲尔德(贫困指数为 78%)。教师将与研究人员密切合作,双方将共同创建教育材料,并将重点放在探究性学习并将基础科学过程与当前研究相结合。所开发的单元将通过课程资源网站广泛提供。
