Sedimentary records suggest that the mid-Proterozoic (ca. 1.8–0.8 Ga) was persistently characterized by a greenhouse climate despite significantly lower solar luminosity compared to modern levels. To maintain greenhouse conditions, the partial pres

Marine red beds (MRBs) are common in sedimentary records, but their genesis and environmental implications remain controversial. Genetic models proposed for MRBs variably invoke diagenetic or primary enrichments of iron, with vastly different implica

Stratiform or layered siderites are much less common than siderite concretions in the stratigraphic record. In the middle part of the Mesoproterozoic Xiamaling Formation (ca. 1.40–1.35 Ga), layered siderites are widespread across the North China Pl

Authigenic glaucony precipitation in Phanerozoic oceans takes place mostly in middle shelf to upper slope environments with low depositional rate or sediment starvation. Precambrian glaucony, however, is more common in stratigraphic successions depos
