National Assessment of Oil and Gas Project - San Joaquin Basin Province (010) Boundary

The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, Total Petroleum Systems are defined and Assessment Units are defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes.

The San Joaquin Basin Province is located in south-central California, encompassing all or parts of Fresno, Kern, Kings, Madera, Merced, Monterey, San Benito, San Luis Obispo, Stanislaus, and Tulare counties. The main population centers within the study area are Bakersfield, Fresno, and Modesto. The province boundary was drawn to include the geologic structures generally considered to be in or bounding the San Joaquin Basin Province.

美国地质调查局（United States Geological Survey, USGS）中部区域能源团队负责评估美国境内的油气资源。美国陆上及州属水域范围内共涵盖71个石油地质省。在这些石油地质省内，将划定总石油系统（Total Petroleum System, TPS），并对评估单元（Assessment Unit, AU）进行定义与评估。各石油地质省均以地质特征为依据划定，多数省界由重大地质变化边界确定。
圣华金盆地省（San Joaquin Basin Province）坐落于加利福尼亚州中南部，覆盖弗雷斯诺、克恩、金斯、马德拉、默塞德、蒙特雷、圣贝尼托、圣路易斯奥比斯波、斯坦尼斯劳斯及图莱里县的全部或部分辖区。研究区内的主要人口聚居地包括贝克斯菲尔德、弗雷斯诺与莫德斯托。该省边界的划定范围涵盖了通常被认为属于圣华金盆地省或构成其省界的地质构造。
