项目摘要
Subduction zones play a major role in governing chemical cycling between the Earth's crust, hydrosphere and atmosphere and the deeper mantle. In these environments volatile elements (H, C, F, Cl, S and others) mediate mass transfer and elemental cycling, and also strongly influence the processes that lead to the generation, transport and eruption of magmas within subduction zone environments. To investigate the distribution and role of volatile elements and their effect on mass transfer and melting in single subduction system, this study will involve a systematic study of major, trace and volatile elements trapped in melt inclusions from primitive magmas in the Cascade arc in California, Oregon and Washington. The aims are to determine pre-eruptive volatile concentrations and oxygen fugacity conditions for the different primitive magma types found in the Cascade arc, and to use this data to examine the composition of slab- and mantle-wedge derived components along and across the arc, and to test current models for melting and magma genesis in subduction zones. Although the Cascade subduction zone is recognized as an endmember "hot and dry" subduction zone, the role of volatiles in element cycling and magma genesis remains unclear. Existing studies and our preliminary data show that water contents vary and that some primitive Cascade magmas are quite "wet" - with H2O up to 4 to 7 wt.%. Two sampling strategies will be pursued, firstly involving study of lavas from along an east-west cross-arc traverse in the Central Oregon Cascades (Lat. ~43-45 degrees). The Oregon High Cascades region is characterized by the highest recent erupted volumes of mafic magma and contains all major primary magma types found in the arc (HAOT, OIB-like, CAB, and shoshonite). This work will be combined with work on other lavas from selected well-studied locations along the arc. Overall this approach will allow use to identify the volatile composition of the range of different magma types produced within the Cascade arc, and provide insight on the variations in volatile abundances across and along the arc.
俯冲带在控制地壳、水圈、大气与更深地幔之间的化学循环方面发挥着重要作用。在这些环境中,挥发性元素(H、C、F、Cl、S 等)介导质量传递和元素循环,并且还强烈影响俯冲带环境中导致岩浆生成、输送和喷发的过程。为了研究单一俯冲系统中挥发性元素的分布和作用及其对传质和熔融的影响,本研究将对加利福尼亚喀斯喀特弧原始岩浆熔体包裹体中捕获的主量、微量和挥发性元素进行系统研究,俄勒冈州和华盛顿州。目的是确定喀斯喀特弧中发现的不同原始岩浆类型的喷发前挥发物浓度和氧逸度条件,并利用这些数据来检查沿弧和跨弧的板片和地幔楔衍生成分的成分,并测试俯冲带熔融和岩浆成因的当前模型。尽管喀斯喀特俯冲带被认为是端元“干热”俯冲带,但挥发物在元素循环和岩浆成因中的作用仍不清楚。现有的研究和我们的初步数据表明,含水量各不相同,一些原始喀斯喀特岩浆相当“潮湿”——水含量高达 4 至 7 wt.%。将采用两种采样策略,首先是对俄勒冈州中部喀斯喀特山脉(纬度约 43-45 度)东西向跨弧线沿线的熔岩进行研究。俄勒冈州高喀斯喀特地区的特点是最近喷发的镁铁质岩浆量最大,并且包含弧内发现的所有主要原生岩浆类型(HAOT、类 OIB、CAB 和钾钠岩)。这项工作将与弧线沿线选定的经过充分研究的地点的其他熔岩的工作相结合。总体而言,这种方法将允许识别喀斯喀特弧内产生的不同岩浆类型的挥发性成分,并提供对整个弧内和沿弧的挥发物丰度变化的深入了解。
