Greywacke is an old term still sometimes used for a particular type of wacke especially in grey-coloured turbidite sequences. |
|
More distal carpets of wacke sand can extend for thousands of square kilometres across oceanic abyssal plains. |
|
These internal structures are arranged within wacke beds in a regular sequence. |
|
The upper surfaces of wacke beds are less well characterized by sedimentary structures. |
|
The hole continues through a sedimentary sequence comprised of fine to medium grained wacke and local fine siltstone and argillite sections. |
|
The most typical external structures of wacke beds are sole markings, which occur on their undersurfaces. |
|
The hole anchored in bedrock at 13.0 metres and cut through wacke with local hematite and epitode alterations to 274.4 metres. |
|
The Annascaul Formation is at least 500 m thick, and is dominated by mudrocks with subordinate quartz wacke sandstones, tuffaceous fine conglomerates and melange. |
|
The lower portion of the hole cored wacke. |
|
It contains fragments of volcanics, 0.5 to more than 6.0 centimeters in size, consisting of felsic to mafic volcanics, as well as chert blocks, in a wacke type matrix. |
|
One is to call the sandstone an arenite, and the other is to call it a wacke. |
|
The Long Creek Formation consists of laminated quartzose argillite and sandstone interbedded with altered basaltic rocks and minor quartz-rich lithic wacke. |
|
The three major arenite sandstone families are separately described below, but the varieties of wacke can be conveniently considered together as a single group. |
|
The middle clastic interval is characterized by shale, siltstone, wacke, and lesser sandstone and breccia, and is tuffaceous in places. |
|
Petrographically, the sample is subarkosic wacke with sub-rounded grains. |
|
Trucker Perry Wacke, 32, of Rotterdam, and chef You Yi, 38, and Ying Yo, 29, of South Woodford, Essex, also face charges. |
