Pouba 1970 stated that the origin of amphibole of the banded magnetite–quartz and magnetite–amphibole rocks is unclear The occurrence of amphibole may either reflect the original composition of the protolith or may be due to the influence of basic intrusions of the Sobotín Massif Pouba 1970More Details
Graphite which occurs in the early Precambrian banded iron formation BIF 31x109yr at Gongchangling Anshan China can be divided into two genetic types on the basis of its modes of occurrence biogenic and inorganic the former occurs in garnetmicaquartz schist and the latter in rich magnetite ore The garnetmicaquartz schist is located at the bottom of the formationMore Details
