Highlights•We study mudstone geochemistry in marine ramp setting.•Enrichment in Fe, P, Mo, As and Sb, excluding U may be a proxy to iron shuttle.•Limitation in reactive iron increases sulfurization-induced protection of OM.•It may be also the case for marine environments with no strong productivity•Iron supply is a key factor for (in-)organic geochemistry of margin sediments.
