9305282 Lerner-Lam This research is a continuation of a collaborative effort of four universities to use the PASSCAL portable broad-band seismometer array facility for a comprehensive imaging study of the lateral transitions in mantle structure beneath the Rocky Mountain Front. Field work was completed under the first grant and this will complete the analysis and synthesis of the data. The Front Range of the Colorado Rockies marks the eastern boundary of heavily tectonized western North America and the western physiographic boundary of the stable continental interior. Earlier studies show that their is a major lateral transition in seismic velocities across the Front Range transition, but its details are poorly understood. Understanding this transition will provide constraints on models of western U.S. dynamics and evolutionary models of the North American craton. ***

这项研究是四所大学合作努力的延续，利用pascal便携式宽带地震仪阵列设备对落基山锋下地幔结构的横向转换进行全面的成像研究。实地工作已在第一笔赠款下完成，这将完成数据的分析和综合。科罗拉多落基山脉的前山脉标志着构造强烈的北美西部的东部边界和稳定的大陆内部的西部地理边界。早期的研究表明，这是一个主要的横向地震速度过渡，但其细节尚不清楚。了解这一转变将为美国西部的动力学模型和北美克拉通的演化模型提供约束。＊＊＊
