勘探概况 MJT断褶带长约120公里,宽20公里左右,是地槽和地台的过渡地带,断裂褶皱发育,以近南北向褶皱为主,总的轮廓是个大复背斜。断褶带表层岩性多变,低降速层厚度不均,造成了地震地质条件的复杂性。 一
Exploration Profile MJT fold belt is about 120 km long and about 20 km wide. It is a transition zone between the earth trough and the platform. The rupture folds developed mainly in the near south-north fold, and the general contour is a large complex anticline. Fluctuations in the fold-fold surface have varied layers and the velocities of the low velocity layers are not uniform, which has caused the complexity of the seismic geological conditions. one
