Geology of Saudi Arabia - Wikipedia
The marl, limestone and shale units taken together do store groundwater and communities in the Eastern Province often draw on the Alat aquifer in the Khobar Member. Groundwater conditions vary widely within Cenozoic units. Al Hasa and Al Qatif are examples of oases, fed by artesian wells.
Little Limestone Lake - Must Visit Natural Wonder in Manitoba
Little Limestone Lake is the world's largest example of a marl lake, which is a calcium carbonate-rich lake. When it's warm out, the marl forms into calcite and separates from the water, which creates crystals and leads to the turquoise hue in the water (what you find in the Caribbean).
Limestone subsoil, chalk subsoil, good soil drainage ...
The subsoil in Champagne is predominantly limestone. So too are the outcrops of sedimentary rock (75% limestone), composed of chalk, marl and limestone proper. This type of subsoil provides good drainage and also imparts that particular mineral flavour found in certain Champagne wines. Regional differences in subsoil

The Arkadelphia Marl is chiefly marl and marly clay containing sandy clay and limestone, and impure chalk. All of these Cretaceous formations dip gently to the south-southeast and crop out along the same trend. In Arkansas, the Marlbrook Marl is currently used as a …
The alluvial confining unit (ACU) consists of Holocene to Pliocene playa, lake, marsh, and spring-deposited clay, marl, limestone, silt, sand, gravel; evaporite deposits, and thin tuff layers. The ACU tends to be a regional confining unit, but limestone and sand layers can be productive local aquifers, although the limestone component is ...

· The contribution of event deposits to various basin fills can be very significant, higher than 90% in some cases. Events may lead to the formation of marl–limestone alternations, which can also result from cyclic changes in sea level or climate, for example.

Ordovician limestone-marl alternations in the Oslo-Asker District have been interpreted as signaling glacio-eustatic lowstands, which would support a prolonged "Early Palaeozoic Icehouse".
What is Limestone? (with pictures)
· Limestone is a type of sedimentary rock found in deposits all over the world and used in an assortment of ways. This rock is one of the most common forms of sedimentary rock, with an estimated 10% of sedimentary rock worldwide being composed of limestone.

Limestone is another excellent source of calcium carbonate, but the grades found in Wisconsin can't be used to make cement. Evens so, importing limestone to cement plants in Wisconsin proved more economical than processing marl.

Marl | Geology Wiki | FANDOM powered by Wikia
Marl is a sedimentary rock made of clay and limestone, which belongs to the family of pelitic rocks (clays <0.02 mm, the fine particles in water sales) and a carbonate is a variety of mudstone. The rocks can be both clastic and chemical-biogenic origin.
Kimmeridgian Soil: - Wine Guy
· He identified a unique layer of dark marl which he named Kimmeridgian. It must be noted that the Kimmeridgian soils found in France, differ from that found in England. The layer is a relatively uniform chalky marl, though with thin marly limestone containing rich layers of seashells.
argillaceous limestone - definition - English - Glosbe
This interpretation is supported by the presence of fine, alternating laminae of light grey argillaceous limestone, or calcareous shale, and dark grey silt to sand-rich calcareous shale, as observed in thin section, and the characterization of the lithology for the vertebrate-bearing strata as an interlaminated argillaceous limestone and calcareous shale.

Generally marl soils form a layer 2 to 72 inches (5–183 cm) thick above the limestone bedrock. Drainage of marl soils is poor or very poor. The native climax vegetation is mainly sawgrass, switchgrass, needlegrass, reedgrass, various sedge, reeds, mimosa, buttonwood, and black mangrove.

Environmental changes during marl-limestone formation ...
Limestone-marl alternations are usually interpreted to reflect cyclic paleoenvironmental fluctuations linked to Milankovitch-scale climate variations. However, the impact of diagenesis on lithological differentiation can be overprinted on the primary signal. In order to evaluate environmental variations during the deposition of the Gargasian hemipelagic limestone-marl alternations from the "La ...
