Mineral Resource of the Month: Silver

Silver, one of the eight precious or noble metals, has been used extensively throughout recorded history for various medical purposes, ornaments and utensils, and for its intrinsic value as the basis for trade and monetary systems. Silver has played a significant role in world history, financing a Greek victory over the Persians in 480 B.C., helping Spain become a world power in the 16th and 17th centuries, and helping fund the Union forces during the U.S. Civil War, to give a few examples.

Down to Earth With: Mineralogist George W. Robinson

Many geologists understand the joyous feeling of coming across a beautiful rock in the field; George W. Robinson, who began collecting minerals at age 9, has had a lifetime full of such moments. After delving deeper into his early avocation as a teenager, he received his doctorate in mineralogy from Queen’s University in Kingston, Ontario, in 1979. He has worked as a high school earth science teacher, field collector, mineral dealer, museum curator and professor — all occupations that shared a common focus: a love of minerals.

Geomedia: Books: To Tiktaalik and beyond

In 2008, Neil Shubin penned the terrific, “Your Inner Fish: A Journey into the 3.5-Billion-Year History of the Human Body,” in which he explored the stories of deep time as they are written in the details of our bodily architecture. As both a professor of anatomy and the paleontologist who discovered Tiktaalik, a transitional fossil between fish and amphibians, Shubin was ideally positioned to tell this tale.

On the trail of treasure in the Rocky Mountains

In 2010, collector Forrest Fenn filled a bronze chest with gold, jewelry and artifacts valued at $1 million to $2 million, which he then hid somewhere in the Rocky Mountains north of Santa Fe, N.M., leaving clues to its location in a mysterious poem. Thousands of treasure hunters — including the author, one of EARTH's roving correspondents — are on the trail, but no one has found it yet.

A tantalizing treasure

The contents of Forrest Fenn’s chest are not completely known, but Fenn has listed enough of the treasure to make the hunt truly tantalizing: 20 troy pounds of gold coins, gold nuggets the size of a man’s fist, pre-Columbian Incan and Mayan animal figures, a 17th-century Spanish gold-and-emerald ring, a bracelet with more than 250 rubies, diamonds and Ceylon sapphires, and two hand-carved Chinese jade masks.
