The Cretaceous sedimentary rocks were baked by the basaltic lava flow erupted in the Early Miocene, contracting in volume owing to loss of water contained mainly in the clays of the clastic rocks, and thus forming the columnar jointing. According to the occurrences of jointing and the sedimentary strata the authors calculated the two different rotations of the Mellit block: the block tilted toward 338° for 18° from Late Cretaceous to the beginning of Miocene, and tilted toward 138° for 18° since Miocene.
可以合理地假定柱状节理在形成时是垂直于大地基准面的,根据柱状节理和沉积岩层的产状,笔者计算出Mellit地块的两期旋转事件:自晚白垩世初期到中新世初期该地块向338°方向倾斜了18°,而自中新世以来又向138°方向倾斜了18°。

From the bottom up, the strata are the Fuxian, the Yan'an, the Zhiluo and the Anding Formations. In the past, it was thought that only the Yan'an Formation contains coal in the Jurassic systerm of the basin. However, recent explorations have shown that the Zhiluo Formation also has some minable coal seams in a certain area.
