The phosphorites are of pelletal
type and commonly contain cellophane, dahlite, francolite, glaucophane, dolomite, iron oxide and pyrite in various proportions.
In such contexts, glauconite is an authigenic mineral developed as pelletal
facies (mud coprolites, foraminiferal tests and mineral debris), and less frequently as films growing in holes, cracks and borings on hardgrounds and omission surfaces that may be associated with phosphates (e.
Each cycle began with deposition of carbonate pelletal
mud, micrite, followed upward by fossiliferous calcarenties and an upward shoaling oolite bar.
The programme is to test diamond content of pelletal
claystone sediments at the site.
Whereas most of the northern shoreline is rocky, the eroded edges of the platform along the south coast and parts of the northeast are flanked by a narrow beach of skeletal pelletal
sands and by a belt of low modern dunes (1-2m high).
The remains of repeated small scale camping episodes were uncovered in a palaeosol capping a buried pelletal
Hesse and McTanish 2003) suggesting that there is little clear evidence of pelletal
clay aggregates being transported long distances as dust.
Middle Smackover strata, especially in basinal areas, are dominated by lime mudstone and pelletal
or fossiliferous wackestone, deposited in relatively deep water.
Our building materials all gathered and ready, we killed time by riding along the creek, seeking out scattered greenery and last year's dry grass so the horses could stretch their dwindling supply of pelletal
