Comments on the geologic information

  • GEOLOGY OF THE AREA IS NOT APPLICABLE TO DATA BASE ENTRY. A SUMMARY IS AS FOLLOWS. THE LABRADOR-QUEBEC IRON DEPOSITS (WABUSH, CAROL LAKE, MOUNT WRIGHT AND FIRE LAKE) IS IN FOLDED METAMORPHIC ROCKS IN THE SOUTHERN TROUGH OF THE LARGER LABRADOR TROUGH. THE ORE LIES IN SERIES OF ANTICLINES AND SYNCLINES, AND THE EXPLOITABLE AREAS ARE IN ZONES THAT LIE IN STRUCTURALLY AND PHYSICALLY ACCESSABLE ZONES. DUE TO THE CONTORTION OF THE ROCKS, DIPS AND STRIKES ARE HIGHLY VARIABLE. THE DETAILED STRATIGRAPHY WILL VARY BETWEEN DEPOSITS, BUT THE GENERAL STRATIGRAPHY OF THE AREA IS AS FOLLOWS. . VARIOUS METAMORPHOSED VOLCANICS AND SEDIMENTS IRON FORMATION THICKNESS (M) UPPER MEMBER 50-60 MIDDLE MEMBER 60-80 MIDDLE QUARTZITE 15-20 LOWER MEMBER 60-80 BASAL SILICATE/QUARTZITE 20-25 . THE MIDDLE MEMBER GENERALLY CONTAINS THE RICHEST IRON (UP TO 45%). THE LOWER MEMBER CONTAINS ABOUT 35-40% FE, AND THE UPPER MEMBER IS ONLY MARGINALLY ORE; LARGE SECTIONS OF THIS MEMBER ARE DISCARDED AS WASTE. GENERALY THE IRON FORMATION CAN BE EXPECTED TO BE 30-70 M THICK BUT CAN THICKEN UP TO 250 M IN THE SYNCLINAL TROUGHS.
