Fluid inclusion microthermometry and Raman spectroscopy of fluid inclusions in quartz veins from the Pennsylvanian rocks of the Anthracite belt, eastern Pennsylvania support a deep burial model of coalification in favor of focused orogenic hot fluid flow. High-temperature (250 to 255 °C) trapping of CH4 ± CO2 saturated aqueous fluids and CH4 ± CO2 inclusions indicate fluid trapping at depths of 11.5 to 13.4 km under a cover of Pennsylvanian to Permian(?) syntectonic load. In the folded rocks to the south of the Anthracite belt, CH4 ± CO2 fluid inclusions indicate a sediment load that was up to 16.3 km thick. Re-equilibrated aqueous fluid inclusions from veins in Silurian through Devonian rocks give the same range of trapping conditions but a wide range of fluid salinities suggesting that folding, fracturing, and meteoric recharge resulted in the intermixing of fluids from throughout the stratigraphic succession.

宾夕法尼亚州东部无烟煤带的深层构造埋藏


宾夕法尼亚州东部无烟煤带宾夕法尼亚岩石中石英脉中流体包裹体的流体夹杂物显微测温法和拉曼光谱支持煤化的深埋模型，有利于集中造山热流体流动。高温（250 至 255 °C）捕获 CO2 饱和水流体± CH4 和 CH4 ± CO2 包裹体表明，在宾夕法尼亚至二叠纪 （？） 共构造载荷的覆盖体被困在 11.5 至 13.4 公里的深度。在无烟煤带以南的褶皱岩石中，CH4 ± CO2 流体包裹体表明沉积物负荷高达 16.3 公里。从志留纪到泥盆纪岩石的矿脉中再平衡的含水流体提供了相同的圈闭条件范围，但流体盐度范围很广，这表明折叠、压裂和流星补给导致了整个地层演替过程中的流体混合。
