HOW OLD IS Banded iron formations?
Banded iron formations (BIFs) are cherts (a form of quartz - SiO2) that exhibit an alteration of rust-red and gray bands. The rust-red bands represent oxygen-rich episodes and are colored by ferric iron oxide (Fe2O3) and the gray bands represent oxygen-poor episodes in Earth's early atmosphere. The first appearance of BIFs was in the Archean, 3 billion years ago. Unbanded iron deposits first appear in the Proterozoic, 1.8 billion years ago. Banded iron formations are the largest source for mined iron. ----------------------------------------------------------------------------------------------------------- Banded Iron Formations are sedimentary rocks deposited in Earth's early oceans. Originally Earth had no Oxygen in its atmosphere or oceans and the oceans were full of Iron salts. As life began to establish on Earth it started in the Oceans and as a waste product it produced Oxygen (from photosynthesis). This oxygen reacted immediately with the Iron salts dissolved in the water and Iron Oxide precipitated out to form the banded Iron formations. This went on for billions of years until all the Iron was gone and the Oxygen began to be released into the atmosphere.
When a cation has more than one ionic charge what is used in the name?
When a cation has more than one possible ionic charge you use either just the number (i.e. 2+) if it is in ion form or a roman numeral (II) in a name.
What are 2 good functions of iron?
Iron converts blood sugar to energy. Iron is also essential in the production of red blood cells. The immune system is also dependent on iron.
What component of blood contains iron that binds with oxygen?
Red blood cells contain the substance haemoglobin, which is an iron-based molecule that binds to oxygen molecules for transport around the body.
What kind of food what you eat when you are anemic?
Foods that are rich in iron such as spinach and other dark green leafy vegetables, red meats, beans, and certain fish. It should be noted, though, that spinach inhibits the ability of the body to absorb iron from other foods.
What is the difference between red iron oxide and black iron oxide?
the black iron oxide has reacted with carbon and other impurities
What is Red Iron Oxide used for?

Where does Mars get its red colour?
It gets it from iron(III) oxide dust. Iron(III) oxide is rust.
What is iron oxide used for?

Iron oxide and polar ice caps?
The red planet (or Mars) is a planet that contains both iron oxide and polar ice caps. Mars contains iron oxide in its soil, which gives the planet its red appearance.
What is in the clay that makes it red?
Iron oxide, mostly. I don't really know if there are other minerals that can make it red, but most cases, iron oxide.
Why is Georgia red clay red?
Its the Iron Oxide which is rust that makes it red
What planet has iron in its soil to make it look red?
rust or Iron oxide
What is produced when iron combines with oxygen?
The short answer is iron oxide. However, there are two common iron oxides. When you heat iron in air you get black iron oxide, Fe3O4. In more complex reactions red iron oxide, Fe2O3 is produced.
What causes clay soil to be red?
Iron oxide colors soil red.
What is the chemical which gives red color to red sandstone?
Iron Oxide - rust.
