Only valid for books with an ebook :// Banded iron formations (BIFs) are chemical sedimentary rocks deposited in marine environments mostly during the Precambrian era (James, ).They occur mostly in cratons with – Ga sedimentary sequences, and are classified into two types based on their formation age, size, and associated lithologies (Gross, ).Algoma-type BIFs mainly formed during the Archean and developed in
Hematite, iron oxide, the chief ore of iron, is found in many places in Texas but not in large deposits. This mineral may 67 have a metallic luster and appear reddish brown, dark brown, steel gray, or black or it may occur as a soft, red, earth-like material called red :// Abstract. In Chapter 6 (Sect. ) we introduced the subject of continental rifts and aulacogens, and their related mineral deposits. In this chapter, we take a more detailed look at rifting phenomena, their possible causes, mechanisms, magmatic activity, sedimentation, time and space distribution, associated hydrothermal processes and mineral ://

Natural Resources Canada,;] Sherman Mine is a closed open pit mine in Temagami, Ontario, was a major producer of iron ore, starting production in and closing in Sherman was the largest open pit mine in Temagami, consisting of seven open pits known as the East Pit, South Pit, North Pit, West Pit and the Turtle :// Kent C.
Condie, in Earth as an Evolving Planetary System (Third Edition), Banded Iron Formation. Banded iron formation or BIF is a chemical sediment, typically thin-bedded or laminated with > 15% iron of sedimentary origin (Figure ).BIF has a very distinct distribution with time (Figure ).It is found in minor amounts in the early Archean and in large amounts in the late Archean Distal exhalites ~ m south of the deposit form beds m thick composed of interlayered iron formation and metachert.

The iron formation itself is a laminated IF interpreted as a glacially influenced turbidite. It occurs over an interval of > m. Striated clasts are found within the iron formation (Le Heron et al., a). Narrow units (formation (BIF) occur in the low-grade schist belt of the Maru district, northwest Nigeria.
The schist belt consists of a deformed sequence of pelitic to semi-pelitic phyllites with subordinate iron-formation and quartiztes, and also amphibolites of Routledge & CRC Press are imprints of Taylor & Francis.

Volcanogenic massive sulfide deposits (VMS) are grouped into five lithostratigraphic types, using sequence boundaries defined by major time-stratigraphic breaks, faults, or major (subvolcanic) intrusions: (1) bimodalmafic settings (e.g., Noranda, Urals) occur in incipient-rifted suprasubduction oceanic arcs, typified by flows and g., Cyprus Site formation processes are “the factors that create the historic and archaeological records” (Schiffer,7).These factors include both natural and anthropogenic forces operating in different depositional environments and contributing to postdepositional :// The host rocks are calc-silicate rock, marble, pyritic/carbonaceous metasediments, and iron formation of the Broken Hill Group and Bimba Formation–Ettlewood Calc-Silicate Member.
