Geophysical data and grids of the Grouse Creek and Utah part of the Jackpot 30' x 60' quadrangles, Utah

New geophysical data, including density and magnetic susceptibility measurements, were collected in the Grouse Creek and Utah part of the Jackpot 30' x 60' quadrangles in Box Elder County, Utah and Cassia County, Idaho. The release contains 324 new gravity measurements merged with a 2013 compilation. These data were inverted for basin thickness and basement density variations. The release includes grids of gravity, aeromagnetic, basin thickness, and basement gravity as well as automatically calculated density and magnetization boundaries using the maximum horizontal gravity gradient method. These datasets aid projection of geologic features into the subsurface and supports geologic and geophysical studies in the region.

本研究在犹他州博克斯埃尔德县与爱达荷州卡西亚县境内的Jackpot 30'×60'矩形测区（quadrangle）的松溪片区及犹他州片区，采集了涵盖密度与磁化率（magnetic susceptibility）测量的全新地球物理数据。本次发布包含324组新重力测量数据，并与2013年的汇编数据集进行融合。上述数据被用于盆地厚度与基底密度变化的地球物理反演分析。本发布包涵盖重力、航空磁测、盆地厚度以及基底重力栅格数据，同时包含基于最大水平重力梯度法（maximum horizontal gravity gradient method）自动计算得到的密度与磁化率分界范围。该数据集可辅助地质特征的地下推演，为该区域的地质与地球物理研究提供有力支撑。
