Données géochimiques des échantillons de type "CAB" du domaine "Afrique" :



Jean-Louis JORON et Michel TREUIL
Laboratoire Pierre Süe
Centre d’Études de Saclay – France
Laboratoire Pierre Sue

Les analyses en éléments traces fournies ci-dessous concernent des roches prélevées par carottage terrestre, dragage ou forage océanique profond. Elles ont toutes été réalisées par la même technique : l’analyse par activation neutronique purement instrumentale(*) et en utilisant les mêmes données standards de calibration. La technique a été développée au Laboratoire Pierre Süe (CE Saclay).
*sans nécessité de mise en solution, source d'imprécisions dans le cas d'analyse de roches, du fait de la présence de minéraux "non solubles".

Lexique :

  • CAB : calk-alkaline basalt / Basaltes calco-alcalins
  • CFB (Continental Flood Basalt) ou Trapps,
  • MORB : Middle Oceanic Ridge Basalt / Basaltes des rides médio-océaniques
  • OIB : Ocean Island Basalt / Basaltes des îles océaniques intraplaques
  • Subduction : roches issues de zones de subduction, lieu de destruction de la croûte océanique. Lorsqu’une plaque se heurte à une autre plaque, elle retourne dans le manteau en formant une zone de suduction.
  • Volcanisme d’arc insulaire : les arcs insulaires, répartis en bordure des zones de subduction, résultent de la formation de nouvelle croûte similaire à celle des continents
  • Volcanisme arrière-arc : en arrière d'un arc insulaire, formation de petits bassins dits "arrière-arcs". L’ouverture de ces bassins serait le signe précurseur de la formation d’un bassin océanique.
  • Ophiolite : roches correspondant à la lithosphère océanique, charriée sur un continent par obduction lors de la convergence de deux plaques lithosphériques
  • Magmatisme ancien Magmatisme antérieur à la tectonique des plaques actuelle (antérieur à 500 millions d'années)
    • Archéen : éon précédent le Protérozoïque (de - 4 à - 2.5 milliards d’années).
    • Basalte : roche magmatique rapidement refroidie. C'est le constituant principal de la croûte océanique.
    • Protérozoïque : éon (ou période géochronologique) de la fin du précambrien (de - 2,5 à - 0,541 milliards d’années).
    • Komatiite : roches témoins direct du manteau archéen à olivine et pyroxène.
    • Gabbro : roche magmatique, constituant principal de la couche inférieure de la croûte océanique.
    • Ophite : roche magmatique intermédiaire entre le gabbro et le basalte, qui résulte de la cristallisation d'un magma sans contact avec l'atmosphère .
  • Birimien : âge stratigra^phique équivalent à l'époque paléoprotérozoïque du précambrien (-2.5 à -1.6 Milliards d'années).
  • Les roches de cet âge morceau de croûte terrestre (terrane), essentiellement composé de granites alcalins, agrégé à l'aire continentale sud (craton) de l'Afrique de l'Ouest, âgé de
  • Shale : roche sédimentaire n'ayant pas subi de transformation (métamorphisme) et censée représenter la composition de la croûte continentale primitive.
  • Chondrite et achondrite : météorites avec ou sans "chondres", petites billes composées de silicates, traduisant leur origine primitive ou issue d'astéroïdes.
Echelle des temps géologiques du BRGM.

NB : les références des échantillons suivies de "(d)" indiquent de nouvelles analyses sur des échantillons, précédemment analysés.

Lexique :

  • CAB : calk-alkaline basalt / Basaltes calco-alcalins
  • CFB (Continental Flood Basalt) ou Trapps,
  • MORB : Middle Oceanic Ridge Basalt / Basaltes des rides médio-océaniques
  • OIB : Ocean Island Basalt / Basaltes des îles océaniques intraplaques
  • Subduction : roches issues de zones de subduction, lieu de destruction de la croûte océanique. Lorsqu’une plaque se heurte à une autre plaque, elle retourne dans le manteau en formant une zone de suduction.
  • Volcanisme d’arc insulaire : les arcs insulaires, répartis en bordure des zones de subduction, résultent de la formation de nouvelle croûte similaire à celle des continents
  • Volcanisme arrière-arc : en arrière d'un arc insulaire, formation de petits bassins dits "arrière-arcs". L’ouverture de ces bassins serait le signe précurseur de la formation d’un bassin océanique.
  • Ophiolite : roches correspondant à la lithosphère océanique, charriée sur un continent par obduction lors de la convergence de deux plaques lithosphériques
  • Magmatisme ancien Magmatisme antérieur à la tectonique des plaques actuelle (antérieur à 500 millions d'années)
    • Archéen : éon précédent le Protérozoïque (de - 4 à - 2.5 milliards d’années).
    • Basalte : roche magmatique rapidement refroidie. C'est le constituant principal de la croûte océanique.
    • Protérozoïque : éon (ou période géochronologique) de la fin du précambrien (de - 2,5 à - 0,541 milliards d’années).
    • Komatiite : roches témoins direct du manteau archéen à olivine et pyroxène.
    • Gabbro : roche magmatique, constituant principal de la couche inférieure de la croûte océanique.
    • Ophite : roche magmatique intermédiaire entre le gabbro et le basalte, qui résulte de la cristallisation d'un magma sans contact avec l'atmosphère .
  • Birimien : âge stratigra^phique équivalent à l'époque paléoprotérozoïque du précambrien (-2.5 à -1.6 Milliards d'années).
  • Les roches de cet âge morceau de croûte terrestre (terrane), essentiellement composé de granites alcalins, agrégé à l'aire continentale sud (craton) de l'Afrique de l'Ouest, âgé de
  • Shale : roche sédimentaire n'ayant pas subi de transformation (métamorphisme) et censée représenter la composition de la croûte continentale primitive.
  • Chondrite et achondrite : météorites avec ou sans "chondres", petites billes composées de silicates, traduisant leur origine primitive ou issue d'astéroïdes.
