Structural control of hydrothermal flow: A comparison between the RIDGE2000 sites and the Iceland spreading centers

这项研究对沿沿着RIDGE 2000洋中脊的热液地点、东太平洋海隆、胡安德富卡海脊和劳盆地的重点地点以及广泛研究的冰岛地热区的已知数据进行综合、比较综合和汇编。 对由此产生的共同登记的测深/地形、形态、地质和热液喷口流体化学和喷口位置数据进行分析，可以根据绘制和成像的结构、火山特征和热液矿床，详细了解喷口和喷口地点的分布情况。重复调查和（或）长期监测的数据提供了喷口分布和行为随时间变化的详细情况，以清楚地了解每个地点热液活动的短期演变情况。结果揭示了热源之间的相互作用，流体和可渗透的途径，在海洋浅地壳的热传输，地壳的蚀变，和分布的热液产品/矿床（活动和化石）有直接的影响。 这项工作的更广泛影响包括博士后培训和与冰岛科学家的国际合作。 还将对K-12教室进行公共宣传。

This research carries out an integrative, comparative synthesis and compilation of known data among hydrothermal sites along the mid-ocean ridge at the RIDGE2000 focus sites on the East Pacific Rise, the Juan de Fuca Ridge, and the Lau Basin and extensively studied geothermal areas in Iceland. Analysis of the resulting co-registered bathymetric/ topographic, morphological, geological, and hydrothermal vent fluid chemistry and vent location data allow generation of a detailed picture of the distribution of vents and vent sites with respect to mapped and imaged structures, volcanic features, and hydrothermal deposits. Data from repeat surveys and/or long-term monitoring provide detail on changes in vent distribution and behavior over time to provide a clear picture of the short-term evolution of hydrothermal activity at each location. Results shed light on the interplay between heat sources, fluids and permeable pathways in the ocean shallow crust which has direct implications for the transport of heat, alteration of the crust, and distribution of hydrothermal products/ore deposits (both active and fossil). Broader impacts of the work include postdoctoral training and international collaboration with Icelandic scientists. Public outreach to K-12 classrooms will also be carried out.
