EDITOR’S CORNER
What’s New in Economic Geology
As stated in my previous column, one of
the goals of streamlining the
manuscript submission and review process
is get the journal back on schedule,
with issues being mailed in the month
listed on the cover. This goal was
achieved with the May issue and most
SEG members in North America
received their copies at the end of May;
understandably, international mail
takes a bit longer. Issue no. 4 (June-
July) was mailed by early July so that
all readers should have a copy in their
hands by the end of that month. This
marks the first time in many decades
that this benchmark has been achieved.
The more rapid recent review and publication
process is due to several factors,
including the recent increase in electronic
handling of most aspects of
manuscript submission and review
(approximately 95% of ~140
manuscripts received since July 2008
have been submitted electronically and
80% of these have been submitted
online), the hard work of the editorial
board and dedicated reviewers around
the world, and streamlining of the copyediting,
layout, and journal assembly
process by the dedicated staff in the SEG
Littleton office, particularly Alice Bouley
and Vivian Smallwood.
A second notable change is represented
by the first paper in issue no. 3,
by Braxton et al., on deep oxidation
and exotic Cu formation of porphyry
Cu-Au deposits in the Philippines. This
paper was originally presented at the
2007 SEG Supergene Processes
SEG production staff Alice Bouley and Vivian Smallwood
show their delight at the surprise get-together organized
by Execu tive Director Brian Hoal to celebrate the on-time
publication of Economic Geology.
Symposium held in Tucson, Arizona,
and is one of a dozen papers that will
be published later this year as SEG
Special Publication 14 on Supergene
Processes, edited by Spencer Titley. As a
way of increasing visibility for SEG
stand-alone publications such as
Reviews and Special Publications,
selected individual papers will first be
published in the journal, to receive very
broad distribution, and will then be
included in the forthcoming standalone
publication. Thus, readers who
are interested in a particular subject,
such as Braxton et al.’s outstanding
study of supergene processes, will be
alerted to the availability of additional
papers on similar topics in the standalone
Special Publication.
A final change that has been visible
in the journal for some time is the in -
creasing use of color, where appropriate,
to illustrate articles published in Economic
Geology. As a way of increasing value
for SEG membership, color illustrations
are now free in the journal for SEG
members. Another increase in value is
that all Economic Geology papers back to
1905 (volume 1, issue no. 1) are available
to members online. We will continue
to make changes to increase value
to members and to maintain Economic
Geology’s position as the premiere scientific
journal in our field, as we move
into the 104 th year of publication.
