Lithology description: "The sediments of the Loh Fm. are dominantely trough cross-bedded, poorly sorted, polymict, matrix-supported gravels and sands. [...] Within the Loh Fm. several layers are of aeolian origin and are associated with caliche horizons, which show the same features as those in the Hsanda Gol sediments. Especially these aeolian deposits are rich in fossils, whereas the fluvial facies is poor in small mammals but contains large mammals." (Höck et al., 1999)
Environment:dry floodplain Tectonic setting:rift
Geology comments: "The Loh Fm. probably reflects a fluvial system between a 'shallow, gravel-bed river' and a 'shallow, perennial, sand-bed braided river', but with restrictions to a more ephemeral character." Mudstones are interpreted as eolian dust deposits. (Höck et al., 1999)
