RICH STRIKES is a term used in the field of geology. It refers to a type of ore deposit that is formed when hot, mineral-rich fluids are forced up through fractures in the Earth's crust. The fluids then cool and deposit minerals, such as gold, silver, copper, and lead, along the fractures. The term LODES is an acronym for 'Lead Ore Deposit Environments'. This term is used to describe the geological environment in which these ore deposits form.
