Research on the tectonic-thermal evolution of Lu’an mining area
摘要
Abstract
Through studying the geological background of Lu’an mining area, we recovered the burial and thermal history of the coal-bearing strata of multiple coal mines in the study on the basis on testing and analyzing the vitrinite reflectance. The result shows that from Early Triassic to Jurassic Period, burial depth in the study area in-creased to around 3 500 meters because of the strongly tectonic movement. The study area went through relative high paleogeotherm, 120~135℃, and heat flux reached the first peak value, 76~89 mW/m2. Then from Late Juras-sic to Early Cretaceous Period, the mine lot was influenced by the strongly tectonic movement again, experienced high paleogeotherm, 160~180℃and second palae-heat flux peak, 90~99 mW/m2. In comparison, we conclude that the tectonic-thermal evolution degree in the southeast edge of Qinshui basin is higher than that in the center of Qinshui basin.关键词
