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

该奖项提供了一个涉及康奈尔大学人员和外部调查人员的大陆深部地震反射研究的重点项目。该项目包括：1)在蒙大拿州东部和北达科他州采集超深可控震源/炸药组合地震反射剖面，作为与LITHOPROBE合作研究威利斯顿克拉通盆地和横贯哈德逊造山带的合作项目的一部分。2)获取横跨格鲁吉亚东南部Surrency“亮点”的联合P波和S波扩展扩展剖面，以确定其地震属性，并评估地壳深部亮点来自圈闭流体的可能性。拟议的现场计划利用了Cocorp可用的特殊机会，使用配备了SGR(地震组记录仪)的850通道研究地震反射队。阿莫科制作公司提出将这个团队的硬件免费借给Cocorp进行这些研究。该团队的先进能力将使其能够获得比过去复杂得多的数据，而每英里的成本实际上低于之前的调查。

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.
