Description
This book covers the more basic aspects of carbonate minerals and their interaction with aqueous solutions; modern marine carbonate formation
and sediments; carbonate diagenesis (early marine, meteoric and burial); the global cycle of carbon and human intervention; and the role
of sedimentary carbonates as indicators of stability and changes in the Earth's surface environment. The selected subjects are presented
with sufficient background information to enable the non-specialist to understand the basic chemistry involved. Tested on classes taught
by the authors, and approved by the students, this comprehensive volume will prove itself to be a valuable reference source to students,
researchers and professionals in the fields of oceanography, geochemistry, petrology, environmental science and petroleum geology.
