50 years of incessant SQUID research afford a good opportunity to ask for the impact that SQUIDs have made on the general technical progress. This paper highlights the SQUID applications in geophysics and in particular the efficient and eco-friendly exploration of the Earth's resources, where SQUID technology provides a fundamentally new approach and allows acquiring qualitatively new data sets. After a brief introduction into the history of SQUIDs in geophysics, two applications and according examples will be introduced and discussed which are making impact in mineral exploration today: transient electromagnetics and full tensor gradiometry. A short outlook of the exciting opportunities and perspectives of the use of SQUIDs in other geophysical applications in years to come will be presented.

Perspectives on the 50th Anniversary of SQUIDs (Superconducting Quantum Interference Devices) by Ronny Stolz, with focus on geological applications.
