Marls

The true marls, that is those in which carbonate of lime abounds, are greatly preferable to clay marls, the latter, indeed, operate chiefly mechanically, by altering the texture of the soil -- the lime they contain being frequently too small to exercise much appreciable effect. ❋ Thomas Anderson (N/A)

The sediments at Site 1202 are deposited from low-grade metamorphic schist and marls, which is found within these mountain ranges on the island of Taiwan. ❋ Ariesgogogo (2010)

The lime clays or "marls" of class (2), which contain essentially a high percentage of chalk or limestone, are not so widely distributed as the ordinary brick-clays, and in England the natural deposits of these clays have been largely exhausted. ❋ Various (N/A)

"marls," [1] and may contain as much as 40\% of chalk. ❋ Various (N/A)

In general, it is comprised of a wedged-shaped series of unconsolidated layers of sands, clays and marls on a gently, southeastward dipping bedrock (80 to 100 feet per mile) which is 1,300 to 6,000 feet below the surface. ❋ Unknown (2009)

It marls them out from the beige background and makes them feel like they are "really believing" something....that their version is the correct version because it stands in opposition to the surrounding culture of what they view as "nominal Christianity". ❋ James F. McGrath (2010)

•Underlain by clays, silts, marls, sands, gravels, and shell beds that are lithologically distinct from the rocks of Ecoregions 58, 64, and 67. ❋ Unknown (2009)

Ultisols dominate throughout the region, with locally conspicuous Vertisols formed from marls or soft limestones. ❋ Unknown (2009)

The rolling to nearly level plains of the Northern Blackland Prairie ecoregion are underlain by interbedded chalks, marls, limestones, and shales of Cretaceous age. ❋ Unknown (2009)

The Miocene-age Fleming Formation and to the west the Oakville Sandstone have some calcareous clays and marls, but differ some from the Cretaceous-age formations of Ecoregion 32a. ❋ Unknown (2009)

In general, it is comprised of a wedged-shaped series of unconsolidated layers of sands, clays and marls on a gently, southeastward dipping bedrock 80 to 100 feet per mile which is 1,300 to 6,000 feet below the surface. ❋ Unknown (2009)

The ridge is formed from outcroppings of marls and sands on the Ripley Formation cuesta. ❋ Unknown (2008)

The coastal sediments are made up of marine sediments (marls and limestones) and recent sands laid down in different sedimentary basins. ❋ Unknown (2008)

Ecoregion 35a is underlain by Cretaceous sandy, clayey, or gravelly deposits that are often calcareous; it is lithologically distinct from the Tertiary noncalcareous deposits of Ecoregion 35a, the Quaternary alluvium of Ecoregions 35b, 35g, and 73, and the chalks and marls of Ecoregion 35h. ❋ Unknown (2008)

Poorly drained soils overlie limestone, calcareous sandstones, marls, swamp deposit mucks, and algal muds. ❋ Unknown (2008)

Mineralogically, these oil shales are marls or argillaceous limestones, which may be associated with volcanic tuffs and evaporites. ❋ Ann Althouse (2008)
