Welcome to my Web site!
I owe an apology to all of you who have been coming to this site since its opening on September 23, 1998, and always finding it under construction. It still is, but at least I am now making an effort to work on it.
For over 20 years, since 1979, I have been conducting experimental
studies at high pressures and high temperatures, using first a piston-cylinder apparatus and then later on, since 1986, a split-sphere multi-anvil apparatus. I use an electron microprobe to analyze the experimental products. My main research objective is
the systematic investigation of the phase relations in simple and more complex
chemical systems relevant to Earth, with the main focus on the major elements -
the NCFMAS system and its subsystems (Na2O-CaO-FeO-MgO-Al2O3-SiO2).
I am using this information to help me in deciphering the mineral and chemical
composition of the Earth’s deep mantle, its structure, and its evolution with
time. The results from 1000 piston-cylinder and close to 700 multi-anvil
experiments have been published, so far, in over 100 abstracts for various national and international science meetings,
and in 69 peer-reviewed articles. I have also summarized these results and the results
from phase equilibrium studies at high pressures and temperatures, carried out
mainly in the second half of the last century by many other experimental
petrologists, in a book titled: “Phase Diagrams for Geoscientists: An Atlas of the Earth’s
Interior.” The book was published by Springer-Verlag on March 18,
2003, and can be ordered here from Springer-Verlag, or, with free shipping, from Amazon.com. The book has 462 pages and 288 figures, from which 243
are calculated phase diagrams. This is the largest published collection of the
calculated phase diagrams for the chemical systems relevant to Earth. This is
also the first time that the phase relations at the relatively low pressures of
the lithospheric mantle, mainly applicable in the experimental thermobarometry
of metamorphic rocks and mantle xenoliths, are seamlessly integrated with the
phase relations of the sublithospheric upper mantle and the uppermost lower
mantle, primarily applicable to inclusions in diamond and schocked meteorites.
The “Atlas” would be a truly invaluable guide for your journey to the core. Use the first of the following links to view color
versions of some of these phase diagrams and other figures from the book. I
hope you will like it and use it.
