Table of Salts
| Mineral | Composition | Known or probable occurrence |
|---|---|---|
| Halite | NaCl | Principal constituent of chloride zone and of salt-impregnated sulfate and carbonate deposits. |
| Sylvite | KCl | With halite. |
| Trona | Na3H(CO3)22H2O | Carbonate zone of Cottonball Basin, especially in marshes. |
| Thermonatrite | Na2CO3·H2O | Questionably present on floodplain in Badwater Basin, would be expected in marshes of carbonate zone in Cottonball Basin. |
| Gaylussite | Na2Ca(CO3)2·5H2O | Carbonate zone and floodplain in Badwater Basin. |
| Calcite | CaCO3 | Occurs as clastic grains in sediments underlying salt pan and as sharply terminated crystals in clay fraction of carbonate zone and in sediments underlying sulfate zone. |
| Magnesite | MgCO3 | Obtained in artificially evaporated brines from Death Valley; not yet identified in salt pan; may be expected in carbonate zone of Cottonball Basin. |
| Dolomite | CaMg(CO3)2 | identified only as a detrital mineral; may be expected in carbonate zone. |
| Northupite and/or tychite | Na3MgCl(CO3) and/or Na6Mg2(SO4)·(CO3)4 | An isotropic mineral, having index of refraction in the range of Northupite and Tychite, has been observed in saline facies of sulfate zone in Cottonball Basin. |
| Burkeite | Na6(CO3)(SO4)2 | Sulfate zone in Cottonball Basin. |
| Thenardite | Na2SO4 | Common in all zones in Cottonball Basin and in sulfate marshes in Middle and Badwater basins. |
| Mirabilite | Na2SO4·10H2O | Occurs on floodplains in Cottonball Basin immediately following winter storms. |
| Glauberite | Na2Ca(SO4)2 | Common on floodplains except in central part of Badwater Basin; sulfate zone in Cottonball Basin. |
| Anhydrite | CaSO4 | As layer capping massive gypsum 1 mile (2 km) north of Badwater. Possibly also as dry-period efflorescence on floodplains. |
| Bassanite | 2CaSO4·H2O | As layer capping massive gypsum along west side of Badwater Basin and as dry-period efflorescence in floodplains. |
| Gypsum | CaSO4·2H2O | In sulfate caliche, layer in carbonate zone, particularly in Middle and Badwater basins, in sulfate marshes and as massive deposits in sulfate zone. |
| Bloedite | Na2Mg(SO4)2·4H2O | Questionably present in efflorescence on floodplain in chloride zone. |
| Polyhalite | K2Ca2Mg(SO4)4·2H2O | Questionably present on floodplain in chloride zone. |
| Celestine | SrSO4 | Found with massive gypsum. |
| Kernite | Na2B4O7·4H2O | Possibly present in Middle Basin in surface layer of layered sulfate and chloride salts. |
| Tincalconite | Na2B4O7·5H2O | Probably occurs as dehydration product of borax. |
| Borax | Na2B4O7·10H2O | Floodplains and marshes in Cottonball Basin. |
| Inyoite | Ca2B6O11·13H2O | Questionably present (X-ray determination but unsatisfactory) in floodplain in Badwater Basin. |
| Meyerhofferite | Ca2B6O11·7H2O | Found in all zones in Badwater Basin and in rough silty rock salt in Cottonball Basin |
| Colemanite | Ca2B6O11·5H2O | Questionably present (X-ray determination but unsatisfactory) in floodplain in Badwater Basin. |
| Ulexite | NaCaB5O9·8H2O | Common in floodplain in Cottonball Basin; known as "cottonball" |
| Proberite | NaCaB5O9·5H2O | A fibrous borate with index of refraction higher than ulexite occurs on dry areas in Cottonball Basin following hot dry spells and in surface layer of smooth silty rock salt. |
| Soda niter | NaNO3 | Weak, but positive chemical tests obtained locally. |

Famous quotes containing the word table:
“They were not on the table with their elbows.
They were not sleeping in the shelves of bunks.
I saw no men there and no bones of men there.”
