MINERAL COLLECTING -AND ROCK & GEM

Rock & Gem readers were saddened to learn of the passing of Bob Jones on May 30, 2024. Bob had been a part of this magazine since its inception, contributing more than 1,500 articles and columns, and finishing his lengthy tenure as a contributor with the well-deserved title of editor emeritus. In the September 2024 R&G, editor-in-chief Pam Freeman posthumously honored Bob by reprinting his first-ever R&G article from the September/October 1971 issue.

After noting that this reprint was much longer than R&G features today, I began thinking of the many other things that had changed since Bob wrote that first article 54 years ago. Sweeping transitions have come to mineral collecting and magazine publication, and both R&G and Bob enjoyed ringside seats to observe, participate in and report on these many remarkable changes.

Is Earth's Magnetic Field Linked to Atmospheric Oxygen?

The scientists making the observation were surprised. A time series analysis of geological records over the past 540 million years of Earth history seems to show a highly correlated link between oxygen levels in the Earth's atmosphere and the strength of the planet's magnetic field, and both seem to be slowly increasing in sync.

Is Subduction “Infectious?”

Earth’s surface is composed of huge plates of relatively stable continental crust and oceanic crust that are constantly forming and recycling. Where they meet, subduction frequently occurs, with ocean crust plunging beneath continents. Thus oceans open and close, appear and disappear.
