Felix,

Thank you for pointing out a problem. SEG recommends Times New Roman
fonts for abstracts, therefore segabs.cls uses mathptmx package that
emulates Times fonts. Unfortunately, mathptmx does not provide bold
greek symbols. See, for example, the discussion at
http://comp.gatago.net/comp/text/tex/11312882.html

Several options here:

1) Don't use bold greek.

2) Don't use Times font - comment out \RequirePackage{mathptmx} in
segabs.cls to return to LaTeX's default Computer Modern fonts.

3) Use "poor man's bold" with the help of bm (bold math) package.

\documentclass{segabs}
\usepackage{bm}
\begin{document}
Compare $\Delta$ and \bm{\Delta}$.
\end{document}

4) Buy commercial fonts such as mathtime
http://www.pctex.com/mtpro2.html or tmmath

If you use the svn version, please update again. I have been playing
with different font sizes, and the version you had may not be the
correct one. Playing is over now: I will release a new stable version
(with slightly larger fonts than before) in a couple of minutes.
