Hawley Medal

The Hawley Medal is awarded to the authors of the best paper to appear in The Canadian Mineralogist in a given year.

The award is named in honor of Dr. J.E. Hawley (1897-1965) who was distinguished professor of mineralogy at Queen’s University.

The paper is selected by a committee of three members selected by the Chair of the Nominating Committee.

A microbeam XAFS study of aqueous chlorozinc complexing to 430?C in fluid inclusions from the Knaum?hle granitic pegmatite, Saxonian Granulite Massif, Germany.
Can. Mineral. 36, 511-524

This paper was selected for its innovative approach to the study and interpretation of fluid inclusions and its influence in opening up new areas of research and for its application of synchrotron radiation. Anderson and colleagues have been pioneers in the application of synchrotron radiation to mineralogical research. Papers such as this year’s Hawley demonstrate the potential of the technique to complement our existing toolbox for research on solids, liquids and gases.

F. Hawthorne (1997)
Short-range order in amphiboles: a bond-valence approach.
Can. Mineral. 35, 203-218

Professor Hawthorne describes clearly and concisely short-range order, its importance to understanding minerals and mineral growth, the difficulty in quantifying short-range order, and a method for estimating its frequency in crystals. The rest of the paper applies the theory to estimating short-range order in amphiboles. These results will be important to develop thermodynamic models for amphiboles.

D.S. O’Hanley, F. Wicks (1995)
Conditions of formation of lizardite, chrysotile and antigorite, Cassiar, British Columbia.
Can. Mineral. 33, 753-773

The paper exhibits outstanding research qualities, in addition to being well presented and scientifically sound. The skillful blending of observations, experimental data and theory has resulted in an important contribution to our outstanding of the genesis of assemblages of serpentine minerals. The paper illustrates particularly well the variety of techniques that must be mastered to understand the complexities of nature and amply demonstrates the value of mineralogy in its own right, as well as its role as a critical supplement to other sub-disciplines.
