Gravity, aeromagnetic, magnetic potential, and physical property data of the Bartlett Springs fault zone and surrounding areas, California

This data release contains principal facts of gravity measurements collected by the U.S. Geological Survey in 2020-2022, a compilation of existing and new density and magnetic susceptibility data, and gridded magnetic and magnetic potential data of the Bartlett Springs Fault Zone and surrounding areas, northern California. These data support modeling of gravity and magnetic anomalies to characterize serpentinite bodies along the Bartlett Springs Fault zone as a proxy for fault creep and understand structure along the Coast Range-Sacramento Valley interface.

本次发布的数据包含美国地质调查局（U.S. Geological Survey）于2020至2022年采集的重力测量核心数据集、现有与新增的密度及磁化率（magnetic susceptibility）数据汇编，以及加利福尼亚州北部巴特利斯普林斯断层带（Bartlett Springs Fault Zone）及其周边区域的网格化磁测与磁势数据。本数据集可用于支撑重力与磁异常模拟工作，以刻画该断层带沿线的蛇纹岩岩体特征，将其作为断层蠕变的替代指标，并解析海岸山脉（Coast Range）-萨克拉门托谷（Sacramento Valley）交界带的构造结构。
