DEF

An iron formation in which the principal iron minerals are silicates, such as greenalite, stilpnomelane, minnesotaite, and iron-rich chlorite...

OBS

Banded iron formation is characterized by its fine layering. ... The simplest and commonest BIF consists of alternating hematite and chert layers. ... James (1954) identified four important facies of BIF. (a) Oxide facies. ... (b) Carbonate facies. ... (c) Silicate facies. ... (d) Sulphide facies.

Record 2 1999-06-11

English

Subject field(s)
  • Chemical Engineering
  • Geology
OBS

Siderite cement characterizes some sandstones; but because of its instability and easy oxydation, it is seen only in cores and other fresh samples and seldom or never in natural out croppings.

OBS

Sideritic sandstones are sometimes formed by the alteration of original silicates, such as chamosite, glauconite, or greenalite.

OBS

«Grès à ciment de sidérite». - Ce sont des roches invariablement rattachées aux minerais de fer paléozoïques, dont elles représentent des variétés trop pauvres pour être misent en valeur. Leur gangue est formée de grains de sidérite, moulés les uns sur les autres ou tendant vers la forme géométrique, et exceptionnellement des menus rhomboèdres, généralement allongés et sublenticulaires.

CONT

Los depósitos marinos de cal y arena [...] contienen con frecuencia pequeñas cantidades de los minerales de silicato de hierro llamados glauconita y chamosita, y el carbonato de hierro denominado siderita (calibita).
