Participant Support for a GSA Thompson Field Forum: Processes controlling the growth and evolution of continental batholiths, Coast Mountains British Columbia Canada

这项提案为学生参与和早期职业教师参加美国地质学会汤普森田野论坛提供了支持。论坛的参与者将研究将于2018年8月12日至17日举行的泰瑞斯和鲁伯特加拿大王子之间横跨海岸山脉岩基的横断面上的重要野外关系。除了实地考察，晚上的技术会议还将涉及岩浆作用、大陆生长以及碰撞、增生和平移构造的过程。不列颠哥伦比亚省的海岸山脉岩基是举办论坛的理想地点，因为它是地球上最大的岩浆杂岩之一，它在结构、成分和岩石出土深度上沿走向和交叉走向表现出显著的变化。特别是，论坛将审查高通量岩浆事件的概念。越来越多的来自全球上下地壳暴露的熔岩的数据表明，大多数熔岩是由侵入体组成的，侵位时间相对较短(数千万年)，称为高通量事件(HFE)。实地停留和讨论将集中在对识别触发这些高通量岩浆事件的机制至关重要的位置。论坛将讨论的具体议题包括：1)岩基岩浆的来源是什么；2)高通量岩浆事件的触发机制是什么；3)大规模平移断裂对岩基建筑的规模和意义是什么？对这次论坛的支持将帮助十名学生和早期职业教师参加这一独特的活动并从中受益。论坛的差旅和后勤支持将通过提高与会者整合现场科学、分析科学和基于模型的科学的意识和能力，直接加强STEM这一重要学科的科学教育。参与者将处于向研究界和公众传播这些想法的绝佳地位，这些经验将极大地促进他们未来的科学事业。美国地质学会将编制一份公开的文件，描述野外地块和相关的地质综合。

This proposal provides support for student participation and early career faculty to participate in a Geological Society of Geological Society of America Thompson Field Forum entitled." Participants of the forum will examine important field relationships along a transect across the Coast Mountains batholith between Terrace and Prince Rupert Canada that will be held August 12 to 17, 2018. Along with the field trip, evening technical sessions will involve talks and discussion regarding processes of magmatism, continental growth, and collisional, accretionary, and translational tectonics. The Coast Mountains Batholith, British Columbia is an ideal location for forum because is one of the largest magmatic complexes on earth and it exhibits significant along strike and cross strike variations in structure, compostion, and depths from which the rocks have been exhumed. In particular, the forum will examine the concept of high flux magmatic events. A growing body of data from upper and lower crustal exposure of batholiths around the globe indicate that most batholiths are comprised of intrusions that are emplaced during relatively brief time periods (tens of millions of years) known as High Flux Events (HFE). Field stops and discussions will focus on locations that are important for discerning mechanisms that trigger these high flux magmatic events. Specific topics to be addressed during the forum include 1) What are the sources for batholith magmas; 2) What are the triggering mechanisms for high flux magmatic events; and 3) What is the magnitude and significance of large-scale translational faulting on batholith architecture? Support for this forum will provide assistance for ten students and early career faculty to attend and benefit from this unique activity. The travel and logistical support for the forum will directly enhance science education in an important STEM discipline through the participants increased awareness and ability to integrate field, analytical, and model based science. Participants will be in an excellent position to disseminate these ideas to the research community and the general public, and the experience will greatly enhance their future scientific careers. A publicly available document describing field stops and related geological syntheses will be produced by the Geological Society of America.
