Intracratonic Basins, Proterozoic Layered Complexes, and Fluids in the Crust: A Three Component Program of COCORP Deep Seismic Reflection Research

该奖项为大陆深层地震反射研究提供了一个重点项目，涉及康奈尔大学的人员和外部调查人员。该计划包括：1)在蒙大拿州东部和北达科他州获得超深组合可控震源/炸药地震反射剖面；作为与LITHOPROBE合作项目的一部分，研究威利斯顿克拉通内盆地和下伏的跨哈德逊造山带。2)获取横跨乔治亚州东南部surcy“亮点”的P - S波扩展扩展剖面，以确定其地震属性，并评估深部地壳亮点源自被捕获流体的可能性。拟议的现场项目利用了COCORP的一个特殊机会，使用配备有850通道、SGR（地震组记录仪）的研究地震反射机组。阿莫科生产公司将向COCORP免费提供该团队的硬件，用于这些研究。这批船员的先进能力将使他们能够获得比过去更复杂的数据，而每英里的成本实际上比以前的调查要低。

This award provides for a focused program of continental deep seismic reflection research involving Cornell personnel and outside investigators. This program includes: 1) Acquisition of ultradeep combined vibroseis/dynamite seismic reflection profiles i eastern Montana and North Dakota, as part of a cooperative program with LITHOPROBE to study the Williston intracratonic basin and underlying Trans-Hudson orogen. 2) Acquisition of a combined P and S wave expanding spread profile across the Surrency "bright spot" in southeastern Georgia to determine its seismic attributes, and assess the possibility that deep crustal bright spots originate from trapped fluids. The proposed field program takes advantage of a special opportunity available to COCORP to use an 850-channel, SGR (Seismic Group Recorder) equipped, research seismic reflection crew. Amoco Production Company is offering to lend the hardware for this crew to COCORP free of cost for these studies. The advanced capabilities of this crew will allow the acquisition of greatly more sophisticated data than in the past, at a cost per mile that is actually less than that of previous surveys.
