Abstract

The invention discloses an ore prospecting method for a Carlin type gold deposit. The ore prospecting method comprises the steps of: field screening, indoor screening, rare earth geochemical index andcarbon-oxygen isotope geochemical index recognition, ore prospecting geochemical index system establishment, abnormal graph drawing to guide ore prospecting and the like. The method can be used for rapidly guiding Carlin-type gold deposit prospecting prediction, improves the prospecting efficiency, also can be used for judging the ore-forming fluid migration path of Carlin-type gold deposit and indicating a prospecting direction, has very high popularization and application value, solves the problems of long period, high investment and high risk of existing exploration technology, realizes the economical efficiency and high efficiency of Carlin-type gold deposit potential evaluation and ore right decision, is also one of important ways for realizing green exploration, and solves the ecological environment problem possibly caused in the traditional exploration technology implementation process.

Description

technical field

[0001] The invention belongs to the technical field of mineral resources prospecting, and in particular relates to a method for prospecting a Carlin-type gold deposit. Background technique

[0002] Carlin-type gold deposits are the most important type of gold deposits in the world, and their gold resource reserves account for about 10% of the total metal reserves. Because gold in this type of gold deposit exists in the form of invisible gold, the traditional prospecting and exploration technology is not effective for this type of gold deposit, which seriously restricts the major breakthroughs in the prospecting of Carlin-type gold deposits and also restricts the exploration of gold deposits. Potential evaluation and mineral rights decision-making of Carlin-type gold deposits. Calcite is a main gangue mineral in Carlin-type gold deposits. It is formed throughout the entire ore-forming process of Carlin-type gold deposits and records the ore-forming informatio...
