2021-11-18  Gold is a very rare substance making up only ~3 parts per billion of the Earth's outer layer (imagine 1 billion smarties in one place and only 3 of them were made of gold!). Its rarity and physical properties have made gold one of the most prized of the Earth's natural resources. When gold is found in rocks it is almost always in a pure state.

2008-3-1  The factors that control the concentration of gold at certain sites in the Earth's crust to deposit level as well as the ultimate source of the gold in the various deposits remain, however, topics of debate (e.g. Bierlein et al., 2006, Groves et al., 2005). Even on a scale beyond that of ore deposits, gold is distributed unevenly in Earth.

Orogenic gold and geologic time: a global synthesis

To a large extent, the preserved geological record of this time indicates that this was a period of worldwide major extension, intracontinental rifting, and associated anorogenic

Earth's continental crustal gold endowment ScienceDirect

Due to their generally shallow crustal level of formation, they have a low preservation potential. In contrast, those gold deposits that form at greater depth are more widespread also in older rocks. This explains the high proportion of orogenic (including intrusion-related) gold (32%) amongst all known gold deposits.

How is gold made? Question Date: 2002-10-01: Answer 1: Gold is made in the interior of massive stars. When these stars end their lives, they often blow up and produce SUPERNOVA. During these giant explosions many elements that have high atomic number get made. This is where the gold (Au) comes from. Au is the way to write the symbol for gold.
