a TOC content for sites along a proximal-to-distal transect (i.e., from BWZ to Yan56) relative to the volcanic center located on the southwestern margin of the North China Craton. The locations of the wells and outcrop are shown in Fig. 1; b Model of nutrient element migration and redox conditions during volcanic eruptions of the Chang 7 Member in the Ordos Basin. Near the volcanic center, the level of anoxia in the lake basin increased, and nutrient P was recycled into the water column.
