项目摘要
Intellectual Merit: With mounting evidence that most plutons and batholiths are constructed episodically over timescales of up to millions of years, it is important to reexamine existing methodologies for studying their formation. To understand magma emplacement and cooling histories, multiple ages using several minerals with different closure temperatures and crystal sizes are needed. Likewise, more complex 3D thermal and geochemical scenarios for the magma chamber evolution must be considered. From this perspective, collaborative research is proposed, consisting of field-based integrated high-resolution geochronology, and3D thermal modeling, to investigate a set of related problems - examples include: (1) testing the validity of different episodic growth models, (2) understanding the significance of internal contacts within plutonic bodies, (3) quantifying the extent of chemical mixing or physical mingling, (4) understanding the geometry of intrusion and controls on this, (5) understanding the relations between plutons and related volcanoes, and (6) understanding the sources of hydrothermal fluids and their flow patterns around putons at depth. Understanding of these and similar issues will provide insights into magma formation and evolution, development of associate mineralization, and thermal and tectonic processes that drive and accompany magmatism.Broader Impacts: This project will support the involvement of graduate and undergraduate students from CSF and USC in the research. It involves close collaboration with Yosemite Park personnel in a variety of outreach programs in a Park with millions of visitors per year. In conjunction with the research, a variety of educational materials (particularly on the physics of heat flow and resulting thermal, rheological, and microstructural models of episodically constructed chambers) which will be made available to the public. A Tuolumne Intrusive Series (TIS) website regarding research and geology in the Park will be maintained. And the work will have broad scientific applicability.
智力优势:随着越来越多的证据表明,大多数岩体和岩基是在长达数百万年的时间尺度上形成的,重新审视现有的研究其形成的方法是很重要的。 为了了解岩浆就位和冷却历史,需要使用具有不同闭合温度和晶体尺寸的多种矿物进行多个年龄。同样,必须考虑岩浆房演化的更复杂的3D热和地球化学情景。 从这个角度来看,建议进行合作研究,包括基于现场的综合高分辨率地质年代学和三维热建模,以调查一系列相关问题-示例包括:(1)检验不同幕式生长模型的有效性,(2)理解深圳湾岩体内部接触的重要性,(3)量化化学混合或物理混合的程度,(4)了解侵入体的几何形状及其控制;(5)了解深圳湾岩体与相关火山的关系;(6)了解深圳湾岩体周围热液流体的来源及其流动模式。 了解这些和类似的问题将提供深入了解岩浆的形成和演化,相关矿化的发展,以及驱动和伴随岩浆作用的热和构造过程。更广泛的影响:该项目将支持来自CSF和南加州大学的研究生和本科生参与研究。它包括与约塞米蒂公园工作人员密切合作,在每年有数百万游客的公园开展各种推广计划。与研究相结合,将向公众提供各种教育材料(特别是关于热流物理学以及由此产生的热,流变学和间歇性构造腔室的微观结构模型)。将维护一个关于公园研究和地质的图奥勒米侵入系列(TIS)网站。 这项工作将具有广泛的科学适用性。
