目前,大多数的学者都一致认为,红色层基本上是典型的陆相沉积,偶或是泻湖相沉积。他们认为,红色层是在干旱气候条件下的山前平原上生成的。大地构造环境是产生红色层的决定性因素。Л.Б.鲁欣指出,这一类型的沉积与上升的山脉有着密切的联系,但是他又认为,红色层同时又与海盆有关。 At present, most scholars agree that the red layer is basically a typical terrestrial sedimentation, and even lagoon deposition. They believe that the red layer was formed on the piedmont plain under arid climates. The tectonic setting of the earth is the decisive factor in producing the red layer. Lushing pointed out that this type of sedimentation is closely linked with the rising mountains, but he also believes that the red layer is also related to the basin.
