More
than half of the world's petroleum is to be found in carbonate rocks,
for example in the Middle East, the former USSR and in North America.
These rocks show a bewildering diversity of grains and textures, due
in part to the wealth of different fossil organisms which have contributed
to carbonate sedimentation, and in part to a wide variety of diagenetic
processes which can radically modify textures and obscure the depositional
fabric.
Careful
petrographic study with a polarising microscope is a key element
of any study of carbonate sediments, as a companion to field or
core logging, and as a necessary precursor to geochemical analysis.
This atlas, which illustrates in full colour a range of features
not attempted in any general textbook, is designed as a laboratory
manual to keep beside the microscope, as an aid to identifying grain
types and textures in carbonates. It will appeal alike to undergraduate
and graduate students and to professionals in teaching institutions,
research laboratories and industry.
