Structural Data for the Columbus Salt Marsh Geothermal Area - GIS Data

Shapefiles and spreadsheets of structural data, including attitudes of faults and strata and slip orientations of faults. - Detailed geologic mapping of ~30 km2 was completed in the vicinity of the Columbus Marsh geothermal field to obtain critical structural data that would elucidate the structural controls of this field. - Documenting E- to ENE-striking left lateral faults and N- to NNE-striking normal faults. - Some faults cut Quaternary basalts. - This field appears to occupy a displacement transfer zone near the eastern end of a system of left-lateral faults. ENE-striking sinistral faults diffuse into a system of N- to NNE-striking normal faults within the displacement transfer zone. - Columbus Marsh therefore corresponds to an area of enhanced extension and contains a nexus of fault intersections, both conducive for geothermal activity.结构化数据的 Shapefiles 和电子表格，包括断层和地层的倾角以及断层的滑动方向。 对哥伦布沼泽地热田周边约 30 平方公里的区域进行了详细的地质测绘，以获取阐明该地热田结构控制的临界结构数据。 记录了走向为 E-至 ENE 的左旋走滑断层和走向为 N-至 NNE 的正断层。 部分断层切割了第四纪玄武岩。 该地热田似乎占据了一个位于左旋断层系统东部端的位移传递带，E-至 ENE 走向的左旋走滑断层在位移传递带内逐渐过渡为走向为 N-至 NNE 的正断层系统。 因此，哥伦布沼泽对应一个增强伸展的区域，并包含断层交汇的枢纽，这些均有利于地热活动。
