Over 650 vivid color photos reveal the geo-collectible fossils and
minerals associated with the first two billion years of earth's
history. The engaging text explores the geology of shield areas and
their associated rocks and minerals. Also examined are pegmatites
and their associated minerals, including attractive minerals and
crystals like emerald and aquamarine. Early minerals and rocks
associated with the formation of the earth's atmosphere are also
revealed-the geologic strata known as BIF (Banded Iron Formation).
Some of the earth's oldest fossils are included, displayed in
outcrops harboring the earliest evidence of life. A variety of
unusual minerals associated with early limestone-like rocks (now
usually found as marble) are revealed, including highly prized
rocks used for decorative carvings as well as gemstones. Greenstone
belts, among the earliest rocks on the planet, are also examined
and their interesting association with much of the earth's gold
deposits is explored. This book is a must for anyone passionate
about geology and paleontology.
