Geophysical exploration for gold. N. R. Paterson & P. G. Hallof. Chapter. 837 Accesses. 1 Citations. Abstract. The world-wide interest in gold that has characterized mineral exploration in the 1980s has had a profound effect on …
This paper is a critical analysis of technological methods used in 154 case studies of successful gold exploration from the early 1990s to present. The purpose of the study is to investigate major gold discoveries over the last two decades. Specifically, we ask which exploration methods brought success for each discovery?
Read this article. To assess common factors and the key exploration methods in gold discovery we analyse 154 case studies of successful gold exploration. Our aim is to highlight what may help find gold in the future.
Geophysical methods and exploration strategies are described, and illustrated by examples from a variety ofgold occurrences. Ashort glossary of geophysical terms isprovided athe end ofthis chapter for those readers less familiar with geophysical techniques and terminology. 12.2Geological and geophysical models.
For gold exploration, important geophysical advances include airborne gravity, routine 3D inversions of potential field data, and 3D modeling of electrical data.
Geophysical Methods in Gold Exploration. Magnetic Surveys: Magnetic surveys measure variations in the Earth's magnetic field caused by underlying rock formations. Gold deposits are often associated with mineralized zones containing magnetic minerals like pyrrhotite and magnetite.
Gold deposits are sought with many techniques, but they are based on geochemical studies. Commonly more than one method is employed. With these methods, the geologist is looking for anomalies. Perhaps, the most important techniques are photogeology and seismic techniques. Photogeology. Photogeology is a very important …
Geophysical tools, including different techniques such as magnetic, self-potential (SP), induced polarization (IP) and resistivity, are important techniques in mineral exploration for ores located in basement rocks.
Key Features. Covers the nature and history of gold. Addresses problems with regard to the framework in which gold resources are explored, developed and exploited. Discusses topics including the geology of gold ore deposits, metallurgical processes and design, evaluation, risk and feasibility.
