Where cleavage is developed during tectonic deformation it can be difficult or impossible to determine whether pre-cleavage structures were developed in lithified
or unlithified sediments.
2000: A new techique for retrieving calcareous microfossils from lithified
Just over 65 million years ago, when the animal died, this was not a lithified
sandstone and consisted of fine sand that was washed away by river streams and that was deposited, along with the remains of other turtles of the Barranc de Torrebilles, at the bottom of one of these rivers.
The only habitat known (Sand hills) consists of calcareous lithified
dunes, used for grazing then (Wilkes, 1856) so that it may have been introduced locally.
16) A large block of this karsted dolomite is integrated into the overlying Sixty mile Formation, (17) meaning that enough time elapsed for it to be uplifted, broken off in a landslide, and integrated into a new sediment matrix which then lithified
into solid breccia.
According to the first hypothesis, arsenic is derived from 'erosion of lithified
sediments and crystalline rocks of the Himalayan range and adjacent regions' ,  and was deposited on floodplains across the lower delta where it was subjected to intense chemical weathering.
This area is known as the Oculina Bank, a series of reefs and high-relief bioherms (thickets of live coral, capping mounds of sediment and coral rubble, built upon an underlying lithified
base structure) constructed by the scleractinian ivory tree coral (Oculina varicosa).
This formation of Pleistocene limestone is believed to have been formed from lithified
calcareous sand dunes associated with ancient shorelines (Clarke 1975:79).
fossil mangrove trunks and rhizoliths (fossilised roots) are abundantly exposed along the outer parts of the wave-cut platform all along the northern coast (Fig.
Research was initiated in 1998 on geochemical methods of exploration for copper porphyry deposits buried under thick, lithified
piedmont gravel cover in the Atacama Desert, Chile.
These ledges have a thin veneer of coral-Halimeda-molluscan sand over a lithified
surface and are subject to occasional periods of high current flow.
During the second stage primary cementation develops and the rock becomes lithified
