Rock structure characterization of a magnetite gneiss with ...

2018-8-1  1. Introduction. Gneiss is a foliated rock formed by regional metamorphism.1, 2, 3 The foliation is typically a banding of contrasting mineral compositions and may be fissile or may be non-fissile depending on the mineralogy and alignment of minerals, particularly micas. The alignment of minerals in the fabric of gneiss can be studied by microscopy4, 5 enhanced by image analysis techniques 6 ...

2018-12-31  In 2018, Australia's EDR of iron ore increased by 3% from 2017 to 49 604 Mt (Table 3). Similarly, there was a 4% EDR increase of contained iron to 24 122 Mt (Table 4). EDR attributable to magnetite deposits have decreased by 1%, likely due to re-assessment of projects and inactivity in the magnetite industry.
