I'll try. So the banded rock on the right is called gneiss. Gneiss is a high grade metamorphic rock meaning at one point it was either a sedimentary or igneous rock. This "starter" rock experienced a high level of pressure and temperature which altered the composition of the rock creating the gneiss.

Gneiss: Mineral information, data and localities.

Although a gneiss is commonly feldspar- and quartz-rich, the mineral composition is not an essential factor in its definition. Varieties are distinguished by texture (e.g., augen gneiss), characteristic minerals (e.g., hornblende gneiss), or general composition and/or origins (e.g., granite gneiss.

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 .

Gneiss. Gneiss is a banded rock, composed of the same minerals as granite, syenite, diorite, gabbro, etc., the crystals of which are mostly large enough to be seen.Thus there are varieties called granite-gneiss, diorite-gneiss, gabbro-gneiss, etc., Gneiss made by metamorphosis of a sedimentary rock is called para-gneiss.

A dike (pink) has cut across this black-and-white banded gneiss. The layers at the top closely resemble the cross-bedding in a sedimentary rock, which is curious. This is known as an augen gneiss, after the large blobs of stretched feldspar crystals known as augen (German for 'eye'). Note that there is a clear gneissic banding also in this sample.

Australia is the largest producer of bauxite, followed by China. In 2017, China was the top producer of aluminium with almost half of the world's production, followed by Russia, Canada, and India. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.
