There are many depositional
settings in which sand is reworked, but the geologically older the sand deposit, the more chance it has had to undergo multiple cycles of sediment reworking (Levson and others, 2012).
REE and Nd isotopes in conodont apatite: variations with geological age and depositional
In cultivated soils, SOC inventories were 29% higher in depositional
areas than in erosional areas, although there was a smaller increase (19%) in SOC concentrations of the surface soil horizon, showing a role of soil layer thickness in SOC pools (i.

environments: Mega end members in geologic time.
The track-bearing lithologic unit represents a period of high-frequency depositional
cyclicity on a very shallow and partly restricted inner shelf.
1992; Kadastik 1994, 1995), were applied to describe and define the main glacigenic depositional
The objectives of this study were to: (1) describe the rock types, associated sedimentary structures, and fossils; (2) relate petrographic thin sections of common rock types to visual descriptions; (3) describe dispersed organic matter (palynodebris) and palynomorphs (spores and pollen) in selected rocks; (4) correlate the two cores and effects of sea level fluctuations; (5) refine formation boundaries; and (6) reconstruct a depositional
model from the dataset.
This ramp contains lithofacies ranging from shallow peritidal deposits in the southern depositional
limit to shoal and outer ramp deposits in the north.
These facies are related to the three depositional
settings (lagoon, barrier, and open marine) of inner, middle and outer portions of a carbonate platform (Fig.
Atlas of Australian and New Zealand hydrocarbon seals; worldwide analogs for cap rocks and intraformational barriers in clastic depositional
It was designed to provide our clients with a comprehensive understanding of depositional
systems, structural evolution, and geological development of the underexplored deeper potential in this highly prospective region.
Tertiary coals exposed in the north-central part of onshore Sarawak are evaluated, and their depositional
environments are interpreted.
The survey will cover 90 square kilometres in the south end of EPL 3403 and will cover depositional
areas 1, 2 and 3 already delineated by previous sampling programes.
The well will target similar Miocene and Oligocene deep water depositional
environment sandstones which form the reservoirs in the nearby Mnazi Bay and Msimbati gas fields.
