The authors synthesized geological, geophysical and geochemical data, and believe that the plate tectonic setting of the study area should belong to the rift valley within the continental plate.

研究表明，本区火山活动应为大陆板块内部的裂谷环境，与消减带无关。 文中还总结了火山活动的时代、规模、顺序、碎屑锥特点。 研究了绳状、渣状熔岩的典型剖面、形成条件及流动方向。

This is apparently related to the tectonic setting of Shandong, namely, the continental margin where the Pacific Plate collided against the Eurasian Plate.

之所以如此，显然与山东所处的大地构造位置，即太平洋板块与欧亚板块相互碰撞的陆缘地带密切相关。
