The mechanical compaction is interpreted based on the presence of bioclastic
The Baltoscandian sea also had a very flat seabed and a low depth gradient, which is reflected in a very smooth lateral sedimentation trend from inner ramp pure bioclastic
carbonates towards outer ramp argillaceous limestones and marls (Fig.
The facies that make up the continental shelf are the platform (silt and clay) and continental muds, sands (quartzose and bioclastic
), terrigenous gravel and shells.
This facies is bioclastic
grainstone and consists of brachiopod shells, bryozoans, ostracods, gastropods, crinoids and mollusks (Fig.
The Lower to Middle Devonian sequence is dominated by two groups of carbonate facies: the first are bioclastic
and biolithic sediments deposited in comparatively shallow, high energy settings while the second are micritic and biomicritic sediments deposited in comparatively deep, low energy settings.
This theme appears to play a vitally significant role associated with several natural disasters, such as landslides, earthquakes, debris flows, and surface collapses, and engineering applications; for instance, how to drive long offshore piles into bioclastic
, calcareous soils or how to choose an applicable PSD of materials in constructing large earth and rockfill dams [1-9].

This salt-tolerant grassland develops in crevices and rocky edges of limestone cliffs of Bonifacio (lower and middle Miocene: bioclastic
limestone (Rossi & Rouire, 1980a, b) with a sandy-silty interstitial matrix.
The well exposed Upper Sinemurian, Pliensbachian and Lower Toarcian deposits cropping out in the coastal cliffs of the eastern part of the Asturias region in northern Spain, are represented by a succession of alternating lime mudstone to bioclastic
wackestone and marl (Fig.

At Locality 1 (Fig.1; GR24[degrees]29'35"N, 54[degrees]38'04"E), the cross-bedded aeolianite is separated locally from an underlying, flat topped, coarsely bioclastic
marine limestone by a 40 cm thick, reddish gypsum layer (Evans and Kirkham, 2005; Kirkham, 2011; Fig.
