- •
Organic-rich marls collected near Madr village in Afghanistan were analyzed.
- •
Marine marls are immature based on multiple proxies but contain a Type IIs kerogen.
- •
Oil seeps at outcrop are interpreted to be locally sourced from the marls.
- •
Marls were deposited in anoxic shallow stratified waters of proto-Paratethys.
- •
Geochemical data suggest laterally equivalent strata are effective source rocks.
