Record 3 2006-12-05

English

Subject field(s)
  • Paleontology
  • Mineralogy
  • Petrography
DEF

Agatized, opalized, petrified, silicified wood; a material composed of opal or chalcedony(agate) and formed by the replacement of the woody matter by silica.

CONT

Fossil wood is more durable, however, [than fossil animal tissues] and is found virtually unaltered in rocks as old as the Cretaceous.

French

Domaine(s)
  • Paléontologie
  • Minéralogie
  • Pétrographie
DEF

[...] fragments ligneux des végétaux morts, qui subsistent enfouis dans les terrains sédimentaires du globe.

CONT

Des bois fossiles, même anciens, peuvent être intacts, notamment dans les lignites, ou encore minéralisés. La minéralisation peut s'effectuer de façon variée : avec du calcaire (bois calcifiés), avec de la silice (bois silicifiés), ou avec d'autres substances minérales.

CONT

Les bois fossiles sont abondants à tous les étages à partir du Dévonien.

English

Subject field(s)
  • Petrography
  • Mineralogy
  • Geochemistry
  • Erosion and Weathering (Geol.)
DEF

Petrified wood formed by the mineralization of wood by silica in such a manner that the original form and structure of the wood are preserved.

OBS

The silica is usually in the form of quartz(chalcedony) or opal and gives rise to the following types : agatized wood, jasperized wood, opalized wood.

OBS

shinarump; chinarump: A colloquial term used in southwestern U.S. for silicified wood.

Domaine(s)
  • Pétrographie
  • Minéralogie

DEF

[...] bois transformé en agate ou en jaspe par l'apport continu de molécules de silice qui ont peu à peu remplacé les cellules du bois (branches et troncs d'arbres) se trouvant en contact avec des eaux chargées de silice.

Record 5 2001-09-11

English

Subject field(s)
  • Petrography
  • Mineralogy
  • Geochemistry
  • Erosion and Weathering (Geol.)
DEF

Rock material formed by the mineralization of wood in such a manner that the original forms and structures of the wood are preserved.

OBS

Most fossil wood of this type is replaced by quartz or opal(e. g., agatized wood, jasperized wood, opalized wood), but other minerals may be involved including azurite, barite, bornite, brucite, calcite, carnotite, chalcocite, cinnabar, coffinite, dolomite, hematite, limonite, malachite, siderite, sphalerite, uraninite, and others.

OBS

See also "silicified wood," "agatized wood," and "opalized wood."
