| Limonite is not a mineral species as such, but rather a mixture of amorphous hydrous iron oxides. |
|
| Furthermore, the textural evidence implies that the main hydrous minerals in this rock, staurolite and biotite, largely predate garnet growth. |
|
| Moreover, magnesian and hydrous magmas such as boninites and lamprophyres apparently find no difficulty in traversing the crust. |
|
| Pulmonary disease due to talc, a group of hydrous magnesium silicates, is almost exclusively encountered after occupational exposure. |
|
| If such adiabatic freezing were to control the ascent of hydrous mafic magmas, basalts would probably never erupt in volcanic arcs. |
|
| The aqueducts provided public baths with hydrous spectacles and private houses with running water and flush toilets. |
|
| These had the refractive indices and gave the chemical reactions of lazulite, which is a hydrous phosphate of aluminum, iron and magnesium. |
|
| If water is locked in hydrous minerals in the Venusian crust, it is perhaps possible that any re-release of water could occur locally during volcanism and lava flow activity. |
|
| The water in the mantle may be contained either in high pressure hydrous phases, or alternatively as small hydrous defects in nominally anhydrous minerals. |
|
| These lands less productive and fragile ate very sensitive to hydrous and wind erosion. |
|
| More likely, however, is that any water would become incorporated in the rock through formation of hydrous minerals as the reaction fronts advance. |
|
| This system often leads to lands fertility loss due to hydrous erosion, to silting up and alkalization. |
|
| Grain-scale brittle dilatancy would increase permeability, readily promoting the influx of CO2-rich hydrous fluids into the fault zone soon after its initiation. |
|
| Opal is poorly crystalline or amorphous hydrous silica that is compact and vitreous and most commonly translucent white to colourless. |
|
| Opaline silica is a friable hydrous silica found near hot springs and geysers. |
|
| Intensely hydrate the skin thanks to oils of Dodder and grape pips and to Impérata Cylindrica which restore its hydrous balance. |
|
| Jadeite dykes are intruded within serpentinites and are the metasomatic products of crystallization from hydrous fluids reacting with the serpentinites. |
|
| Precious opal, a hydrous form of silica, has been a gemstone since Roman times. |
|
| Chondrus crispus and Laminaria digitata algae regulate the hydrous flow and stimulate cell metabolism. |
|
| A complex system of pipeline water of rain collected then in large impluvia was useful for the hydrous provisioning of the area. |
|
|
|
| In the summer months, the finely porous limestone returns water to the vine that it has soaked up during the winter and this prevents any occurrence of excessive hydrous stress. |
|
| Although not exhaustive, one can seriously wonder after this test whether if, because of the heat and of the hydrous stress, some right bank 1990 wines have not started to decline! |
|
| A fat substitute comprising microparticulate beads characterised in that the beads are of a hydrous hydrocolloid gel and are the product of gelation of the disperse phase of an emulsion. |
|
| Chrysoprase, plasma, and prase are names for green varieties of chalcedony coloured by admixed green minerals, such as chlorite, fibrous amphiboles, or hydrous nickel silicates. |
|
| The crude melts are leached with water to give solutions of sodium tungstate, from which hydrous tungsten trioxide is precipitated upon acidification, and the oxide is then dried and reduced to metal with hydrogen. |
|
| Silicon dioxide is an amorphous substance, which is produced synthetically by either a vapour-phase hydrolysis process, yielding fumed silica, or by a wet process, yielding precipitated silica, silica gel, or hydrous silica. |
|
| Eventually, these various phenomena also contribute to limit water infiltration, and therefore limit hydrous reserves for the plants and this, in addition, reduces surfaces of lands suitable for cultivation. |
|
| A method of carrying out ion exchange on a solution using a hydrated metal oxide, characterised in that the solution is contacted with an ion exchange material consisting essentially of hydrous uranium dioxide. |
|
| The volcanic arc is the surface expression of the magma that is generated by hydrous melting of the mantle above the downgoing slab. |
|
| The subducting basalt and sediment are normally rich in hydrous minerals and clays. |
|
| Pyrophyllite, a hydrous aluminum silicate, is the basis for the new product, called Airblock. |
|
| The most abundant ingredient present in face or body powders is talc, a natural hydrous magnesium silicate. |
|
| Water is also bound in hydrous minerals, especially clays and opal. |
|
| The high water content of NE Pacific alkalic magmas suggests that one trace phase in the enriched mantle source is a hydrous phase, possibly phlogopite or amphibole. |
|
| Unlike silicates, says Arrhenius, hydrous iron and manganeseminerals grow and dissolve readily in response to small changes in acidity or electric potential. |
|
| Increasing pressure and temperature experienced by subducted materials converts the hydrous minerals to denser phases that contain progressively less structurally bound water. |
|
| Zeolites have been considered as the hydrous silicates of scaffolds. |
|
| Limited Tenders are invited for Supply Of Hydrous Sodium Acetate, Qty-12,000 Kg In 50Kg Carbouys. |
|
| Hydrous magmas composed of basalt and andesite are produced directly and indirectly as results of dehydration during the subduction process. |
