Greensand \Green"sand`\ (-s[a^]nd`), n. (Geol.) A variety of sandstone, usually imperfectly consolidated, consisting largely of glauconite, a silicate of iron and potash of a green color, mixed with sand and a trace of phosphate of lime.

Note: [hand]Greensand is often called marl, because it is a useful fertilizer. The greensand beds of the American Cretaceous belong mostly to the Upper Cretaceous.

Douglas Harper's Etymology Dictionary

"clayey soil used for fertilizer," late 14c., from Old French marle (Modern French marne), from Late Latin marglia, diminutive of Latin marga "marl," which is said by Pliny to be a Gaulish word, but modern Celtic cognates are considered to be borrowed from English or French. As a verb by late 14c. Medieval Latin margila is the source of Dutch mergel, German Mergel.


alt. A mixed earthy substance, consisting of carbonate of lime, clay, and possibly sand, in very variable proportions, and accordingly designated as calcareous, clayey, or sandy. n. A mixed earthy substance, consisting of carbonate of lime, clay, and possibly sand, in very variable proportions, and accordingly designated as calcareous, clayey, or sandy. vb. To cover, as part of a rope, with marline, marking a peculiar hitch at each turn to prevent unwinding.


n. a loose and crumbling earthy deposit consisting mainly of calcite or dolomite; used as a fertilizer for soils deficient in lime


__NOTOC__ Marl or marlstone is a calcium carbonate or lime-rich mud or mudstone which contains variable amounts of clays and silt. The dominant carbonate mineral in most marls is calcite, but other carbonate minerals such as aragonite, dolomite, and siderite may be present. Marl was originally an old term loosely applied to a variety of materials, most of which occur as loose, earthy deposits consisting chiefly of an intimate mixture of clay and calcium carbonate, formed under freshwater conditions; specifically an earthy substance containing 35–65% clay and 65–35% carbonate. It also describes a habit of coralline red alga. The term is today often used to describe indurated marine deposits and lacustrine (lake) sediments which more accurately should be named 'marlstone'. Marlstone is an indurated (resists crumbling or powdering) rock of about the same composition as marl, more correctly called an earthy or impure argillaceous limestone. It has a blocky subconchoidal fracture, and is less fissile than shale. The term 'marl' is widely used in English-language geology, while the terms Mergel and Seekreide (German for "lake chalk") are used in European references.

The lower stratigraphic units of the chalk cliffs of Dover consist of a sequence of glauconitic marls followed by rhythmically banded limestone and marl layers. Upper Cretaceous cyclic sequences in Germany and marl– opal-rich Tortonian- Messinian strata in the Sorbas basin related to multiple sea drawdown have been correlated with Milankovitch orbital forcing.

Marl as lacustrine sediment is common in post glacial lake-bed sediments, often found underlying peat bogs. It has been used as a soil conditioner and acid soil neutralizing agent.

Usage examples of "marl".

Really, it would be more interesting to lunch with the waterbound students than sitting in the cafeteria while her own lunch wilted watching that nasty boy, Marl Fidd, make threatening faces at Khiindi and make fun of Hap for talking all the time.

When he hit the water, he should have landed hard and possibly injured the parts Marl had not already broken, but instead something held him up and he drifted rather than smacked down to the surface of the pool.

As for Marl, Khiindi thought for a moment that perhaps he was a shapeshifter who was really at least partly descended from the Khleevi, the horrible buglike race that had had no purpose except to waste, destroy, and eat the rest of the universe.

Khiindi mewed weakly and tried to drag himself forward, giving Shoshisha and Marl as wide a berth as possible.

With his strength, Elviiz could have prevented Marl from causing more harm to Khiindi without damaging him so badly.

If you want to help him, you should take your special poultice up to Marl and see if you can help.

She hoped that Marl, like Thariinye, had some good buried in him somewhere.

Had Marl maybe attacked Khiindi because of the underwear incident, which Shoshisha had confided to a half dozen of her best friends?

All he had left to do was to get this ship back into space and away from the likes of Marl Fidd.

Khorii slept, he tucked himself up tightly against her, ready to defend her against Marl or anyone else.

But on the other hand, she had brought Marl Fidd with her for some reason that Khorii could not fathom.

He was explaining to us a little while ago about how the drive on this particular model of ship works, but then Marl came in and made a remark that upset Jaya.

Elviiz with her maybe, or just send him, but she was not going to be alone with Marl again.

She passed the first cargo bay at a run, half-afraid Marl would jump out and remind her of her promise.

Khorii found Marl, Sesseli, Captain Bates, and Jaya on the bridge, staring at the viewscreen.
