Abundant fibrous calcite veins containing organic-bearing inclusions occur in faulted Lower Paleozoic through Triassic hydrocarbon source rocks in the Dabashan Foreland Belt (DBF). d13CPDB and d18OPDB values of the fibrous calcite range from - 4.8 to -1.9 to per mil and - 12.8 to - 8.4 per mil respectively, which is lighter than that of associated carbonate host rocks ranging from - 1.7 to + 3.1 per mil and - 8.7 to - 4.5 per mil. A linear relationship between d13CPDB and d18OPDB indicates that the calcite veins were precipitated from a mixture of basinal and surface fluids. The fibrous calcite contains a variety of inclusions, such as solid bitumen, methane bearing all-liquid inclusions, and vapor-liquid aqueous inclusions. Homogenization temperatures of aqueous inclusions range from 140 to 196° with an average of 179°. Salinities of aqueous inclusions average 9.7 wt% NaCl. Independent temperatures from bitumen reflectance and inclusion phase relationships of aqueous and methane inclusions were used to determine fluid pressures. Results indicate high pressures, elevated above typical lithostatic confining pressure, from 150 to 200 MPa. The elevated salinity and high temperature and pressure conditions of the fibrous calcite veins argue against an origin solely from burial overpressure resulting from clay transformation and dehydration reactions. Instead fluid inclusion P-T data and geochemistry results and regional geology indicate abnormally high pressures during fluid migration. These findings indicate that tectonic stress generated fracture and fault fluid pathways and caused migration of organic bearing fluids from the DBF during the Yanshan orogeny. 107.6175 108.6435 31.35 32.52250000000001 108.319510891089 32.04961089108913 2008-06-04T00:00:00 2008-07-19T00:00:00 point Dabashan_Foreland_Belt 31.35 107.6175 Sichuan, Shaanxi, China http://en.wikipedia.org/wiki/Sichuan 2008-06-04T00:00:00 32.5225 108.535 2008-07-19T00:00:00 Sampling by hand HAND 726 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Sample code/label Sample label Li Rongxi Sample label LATITUDE Latitude http://en.wikipedia.org/wiki/ISO_6709 Latitude LONGITUDE Longitude http://en.wikipedia.org/wiki/ISO_6709 Longitude Lithology/composition/facies Lithology Li Rongxi Lithology Homogenization temperature Th °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Th [°C] (Linkam THMS600 microscope stage) Homogenization temperature Th °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Th [°C] (Linkam THMS600 microscope stage) Homogenization temperature Th °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Th [°C] (Linkam THMS600 microscope stage) Homogenization temperature Th °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Th [°C] (Linkam THMS600 microscope stage) Homogenization temperature Th °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Th [°C] (Linkam THMS600 microscope stage) Homogenization temperature Th °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Th [°C] (Linkam THMS600 microscope stage) Homogenization temperature Th °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Th [°C] (Linkam THMS600 microscope stage) Freezing point depression Tm °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Tm [°C] (Linkam THMS600 microscope stage) Freezing point depression Tm °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Tm [°C] (Linkam THMS600 microscope stage) Freezing point depression Tm °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Tm [°C] (Linkam THMS600 microscope stage) Freezing point depression Tm °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Tm [°C] (Linkam THMS600 microscope stage) Freezing point depression Tm °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Tm [°C] (Linkam THMS600 microscope stage) Freezing point depression Tm °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Tm [°C] (Linkam THMS600 microscope stage) Freezing point depression Tm °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Tm [°C] (Linkam THMS600 microscope stage) Homogenization temperature Th °C Temperature Θ http://dbpedia.org/resource/Temperature Linkam THMS600 microscope stage http://www.linkam.co.uk/thms600-features/ Li Rongxi Thm Th [°C] (Thm, Linkam THMS600 microscop...)
