National Assessment of Oil and Gas Project - Appalachian Basin Province (067) 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 Appalachian Basin Province is located in the eastern United States, encompassing all or parts of the counties in Alabama, Georgia, Kentucky, Maryland, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia. The main population centers within the study area are Birmingham, Alabama; Buffalo, New York; Cleveland, Ohio; Pittsburgh, Pennsylvania; Chattanooga, Tennessee; and Roanoke, Virginia. The main Interstates are I-20, I-24, I-40, I-59, I-64, I-65, I-66, I-70, I-71, I-75, I-76, I-77, I-78, I-79, I-80, I-81, I-83, I-84, I-87, I-88, and I-90. The Ohio, Susquehanna, Allegheny, Tennessee, Coosa, Delaware, New, Potomac, and Scioto Rivers and their tributaries drain the area. The province boundary was drawn to include the geologic structures generally considered to be in or bounding the Appalachian Basin.

美国地质调查局（USGS）中部地区能源团队负责评估美国境内的油气资源。美国本土及各州管辖海域共划分为71个油气省。在各油气省内，需厘定总石油系统（Total Petroleum Systems），并对评估单元（Assessment Units）进行定义与资源评估。每个油气省均依据地质特征划定边界，多数省界以重大地质变化作为划分依据。
阿巴拉契亚盆地油气省位于美国东部，涵盖阿拉巴马州、佐治亚州、肯塔基州、马里兰州、新泽西州、纽约州、北卡罗来纳州、俄亥俄州、宾夕法尼亚州、田纳西州、弗吉尼亚州及西弗吉尼亚州的全部或部分县域。本研究区域内的主要人口中心包括阿拉巴马州伯明翰、纽约州布法罗、俄亥俄州克利夫兰、宾夕法尼亚州匹兹堡、田纳西州查塔努加以及弗吉尼亚州罗阿诺克。区域内的主要州际公路包括I-20、I-24、I-40、I-59、I-64、I-65、I-66、I-70、I-71、I-75、I-76、I-77、I-78、I-79、I-80、I-81、I-83、I-84、I-87、I-88与I-90。俄亥俄河、萨斯奎哈纳河、阿勒格尼河、田纳西河、库萨河、特拉华河、纽河、波托马克河以及锡奥蒂河及其支流构成区域的主要水系。该油气省的边界划定以通常被纳入或环绕阿巴拉契亚盆地的地质构造为依据。
