However, occasional additions of clastic sediment
(silty alluvium) and fine domestic refuse (ash, dung, food remains etc.
A conceptual review of regional scale control on the composition of clastic sediment
and the co-evalution of continental blocks and their sedimentary cover .
The stratigraphic record is dominated by thick submarine slope and fan deposits reflecting rift basin formation and influxes of large volumes of clastic sediment
, including carbonate debris, from uplifted rift shoulders.
PART 1 MAKING SEDIMENT Chapter 1 Clastic sediment
as chemical and physical breakdown products.
With a combination of geologic and geophysical data on the property, a huge NE trending Precambrian structure (high) has been identified with a thick wedge of keg River-Granite Wash clastic sediment
abutting (onlapping) orthogonally to it.
These IP anomalies and the sampled areas are all associated with strong hydrothermal alteration in Permian carbonate and Jurassic clastic sediment
host rocks, including silicification, sulphidation, clay alteration, decalcification, and breccation.
Until the early 1990s, little was known of the pre-Permian section but it was supposed that clastic sediments
were better represented than they were in the younger section.
Here, I propose to implement a novel approach termed comminution dating , to determine spatial and temporal changes in the transport time of fine clastic sediments
produced by Antarctic subglacial erosion during the Late Quaternary, which is connected to the flux of ice and sediment discharge into the Southern Ocean.
Red clastic sediments
at the base of the lower Triassic indicated that an erosion period started after sedimentation in the mid-Permian and has been dominant on land in the region.
Nd isotopes can provide important information about the provenance of clastic sediments
in marine environments .
Silver-gold-lead-zinc mineralization is hosted in a sequence of Permian marine clastic sediments
and limestone which are overlain by a Jurassic terrestrial sedimentary sequence and underlain by Proterozoic metasedimentary rocks.
The extreme depth and association with development of the Walker Lane leads to the inference the basin is filled with late Tertiary to Quaternary clastic sediments
