Geology (2015) 43 (12): 1111–1112. Banded iron formations (BIFs) have been at the center of many debates in geology, especially regarding the early (i.e., Archean and Paleoproterozoic) Earth and its surface environments. BIFs are chemical sedimentary rocks that have an anomalously high iron content (>15 wt% Fe) and typically contain layers of

Basalt is a fine-grained, extrusive igneous rock, formed from the cooling of molten lava (magma) erupting from volcanoes. Basalt constitutes the Earth's most abundant igneous rock type, estimated to comprise approximately 70% of the planet's crust. It's typically fine-grained and dark in color due to its high content of iron and magnesium.
