Major faults in Iran (flt2cg)

The geology data set for this map includes arcs, polygons, and labels that outline and describe the general geologic age and type of bedrock of Iran. The geologic provinces data set includes arcs, polygons, and labels of geologic and petroleum provinces interpreted and designated by R.M. Pollastro from a number of literature and map resources to assist in the assessment of oil and gas resources for the USGS World Energy Project. The oil and gas field centerpoints data set is a point coverage that marks the approximate centerpoints of oil and gas fields in Iran. Political boundaries are provided to show the general location of country and/or other reference 'political' boundaries.本地图配套的地质数据集包含弧段（arc）、多边形（polygon）与注记（labels），用于勾勒并描述伊朗基岩的大致地质年代与类型。 地质省数据集包含表征地质与油气省的弧段、多边形与注记，相关数据由R.M.波拉斯托（R.M. Pollastro）基于多篇文献与地图资源解译并划定，旨在助力美国地质调查局（USGS）世界能源项目的油气资源评估工作。 油气田中心点数据集为点要素覆盖（point coverage）图层，用于标记伊朗境内各油气田的近似中心点。 附带提供的政治边界图层，用于展示该国及其他参考性政治边界的大致区位。
