These volumes open with a tribute to aca
demician Vladimir Stepanovich Sobolev, who
died several days before the opening of the
Third
International Kimberlite Conference at
Clermont
Ferrand, France. V. S. Sobolev
made major contributions to the field of kim
berlite
and upper mantle petrology through
out his lifetime and did much to spark the
renaissance in this field that led to these con
ferences.
The 28 papers in the
first
volume deal with
the petrology, geochemistry, and structures

The AGU Council and Executive Commit
tee met in San Francisco during the AGU
Fall
Meeting. The Council next meets on
Tuesday, May 28, 1985, in Baltimore. The
Executive Committee will meet in March and
then again just
prior
to the Council meeting
in Baltimore.
Highlights
of the Recent
Meetings
•
Approved a Chapman Conference on the
Modeling of Rainfall Fields, to be held in Ca
racas,
Venezuela, March
24-26,
1986. Also
approved
the cosponsorship of several meet
ings
of other societies. Cosponsored meetings
are
allowed the use of AGU mailing lists and
are
announced in
Eos:
no financial obligation
is incurred by the Union.
•
Approved a new honorarium schedule
for
journal editors for 1985.
•
Approved a
scope
statement for the new
paleoceanography
journal.
Agreed on sched
ule for a similar statement for the new
jour
nal
dealing with global chemical cycles. Publi
cation of the two is slated for 1986.
•
Amended the AGU Bylaws to eliminate
the Membership Committee as a standing
committee. This proposed action had been
of kimberlites and related rocks or with the
processes by which the kimberlites were de
rived.
The 29 papers in the
second
volume
deal with the mantle and crust-mantle
rela
tionships. The papers represent a
good
sam
pling of the excellent work that is currently
being carried out in this field. A few of the
papers
are reviews, but most are new work
with abundant analytical data on the rocks
and their contained minerals. The papers de
scribe a
good
sampling of the global occur
rences, with the exception of those in the So
viet
Union.
Volume I deals with kimberlites and starts
with three papers on the detection of poorly
exposed kimberlite pipes in North America,
East
Africa,
Siberia, and India.
Nine
detailed
papers
describe the geology, petrology, min
eralogy,
and geochemistry of occurrences of
kimberlites and related rocks, including a pa
per
on oceanic carbonatites. Five general syn
thesis papers describe kimberlite occurrences
in China and Western Australia and ultrapo-
tassic rocks in Western Australia and Spain.
The concluding 11 papers comprise analyti
cal, experimental, and theoretical attempts to
understand the physical and chemical
pro
cesses
involved in the formation of these in
triguing rocks.
The initial 16 papers (204 pages) of volume
II are detailed petrology and geochemistry
reported
in
Eos
(September 4, 1984, p. 687)
after
initial passage by the Council in May
1984.
Two considerations of bylaw changes
are
required before they can become
effective.
•
Approved a plan submitted by the Miner
al
Physics Committee to establish a subcom
mittee that will attempt to arrange for the
production of mineral samples of specified
composition, size, and purity for eventual
general distribution to scientists. The sub
committee is to prepare and submit proposals
for
the funding of the production of these
mineral
samples, to issue requests for propos
als to industry, and to insure that the product
delivered is satisfactory. AGU will act as the
contracting agency and distributor of the
samples.
•
Agreed to conduct two awards ceremo
nies in 1985. In the past the awards have all
been presented during the AGU Spring
Meeting. There has been concern that the
number of awards has cut down the opportu
nity
for appropriate citations and responses.
Spreading
the awards over two ceremonies
will
allow more members to attend and per
mit time to make the program more mean
ingful.
•
Extended the Science Policy Seminar
Pro
gram
of the Public
Affairs
Committee an ex
tra
year.
This program is advertised in
Eos
from
time to time.
The Council also approved AGU's
first
3-
year
plan. This plan was put together by a
committee including all of the Executive
Committee members and the principal corn-
studies on mantle rocks from a variety of
sources, both geologically and geographically.
Included are several studies of quite
rare
xe-
noliths, such as a kyanite-coesite-sanidine gar
net pyroxenite, and several studies of inclu
sions in diamonds. The
succeeding
three pa
pers
are similarly detailed studies of xenoliths
from
the lower crust. The concluding 10 pa
pers
mostly involve theoretical constraints or
general considerations on the dynamics of the
mantle.
However, they include two experi
mental studies, one on the phase relations be
tween coexisting garnet and two pyroxenes at
high pressure and one on the enstatite-diop-
side solvus to 60
kbars.
The book was printed from camera-ready
copy, but the editor and the publisher have
done an exceptional job of making the copy
appear
uniform. Most remarkably, even the
photographs, maps, and tables are crisply
leg
ible. The references have been collected to
the end of each volume, thereby providing a
very
convenient, up-to-date
access
to the liter
ature.
I expect that workers in this field will
have
already added these volumes to their li
brary—therefore
I can only recommend the
volumes highly to those others with peripher
al
interest in the mantle.

mittee chairmen and was reviewed by the
sec
tion presidents and presidents-elect. The plan
details goals for the Union and the sections
over
the next 3 years. It will serve as a guide
and stimulus for AGU activities. President
elect Eagleson, who chaired the Planning
Committee, will be presenting the plan to the
membership in an editorial in
Eos
shortly.
The Executive Committee asked the Execu-
i
tive Director to begin the process of formal
application for membership in the American
Institute of Physics.
