通过对郯庐断裂带内马站盆地中沉积岩相和同沉积构造分布特征的详细研究及盆地内凝灰岩夹层中的锆石裂变径迹年龄测定和盆内化石的研究，认为该盆地是一个形成于晚白垩世并与郯庐断裂带活动有关的走滑盆地。该盆地的形成表明郯庐断裂带，至少是其一部分，在晚白垩世时期仍存在明显的走滑活动。
Based on the detailed study of the distribution characteristics of sedimentary facies and synsediments in the Mazhan basin in the Tanlu fault zone and the zircon fission track dating and tuff fossil research in the Tufa interlayer in the basin, the basin is considered to be a Late Cretaceous strata associated with activities of the Tan-Lu fault zone. The formation of the basin shows that the Tanlu fault zone is at least a part of it, and significant slip-walking activity still exists during the Late Cretaceous.
