摘要
本文以解释地震L14、L55测线为重点,结合地面地质、钻井资料对龙门山北段的地层、构造和断层作了系统分析,认为它是以水平挤压力为主形成的推覆构造。并对其构造分带、成生演化、运动方式及推覆规模等作了深入的探讨和油气远景的评价。
Taking explanation of seismic profile L_(14) and L_(55) and combined with surface geology and drilling data, this paper systematically analyzes the strata, structures and faults at northern sector of Longmen Mountains and recognizes that it is a nappe structure formed mainly by horizontal compressive force. The author deeply discusses the zoning of Its structures, their formation and evolution, the fashion of movement as well as the thrusting scale, and evaluates its oil and gas prospects.
