Large ilmenite and titaniferous magnetite deposits... are classified on the basis of mineralogy into two main types : those consisting mainly of ilmenite hosted in massive or layered anorthosite... ;and complex mineral assemblages of titaniferous magnetite and ilmenite in gabbroic anorthosite.

French

Domaine(s)
  • Pétrographie
CONT

Record 7 1992-06-03

English

Subject field(s)
  • Petrography
  • Metals Mining
CONT

Titaniferous magnetite deposits... are most commonly developed in the gabbroic phases at the margins of gabbro-anorthosite intrusive stocks and in the gabbro-diorite stocks, dykes and sills associated with major gabbro intrusions.

CONT

Large ilmenite and titaniferous magnetite deposits related to anorthosite and gabbroic anorthosite metallogenes... occur as irregular masses and disseminations in layered or massive anorthositic and gabbroic intrusions.

CONT

Many small to medium sized magnetite deposits occur in gabbroic intrusions but the really big tonnages occur in the stratiform lopoliths.
