RAJPUT OF ~ OO,~I~TT~3 ON SED1~ATION
1939-1940
Meeti ngs
The Committee on Sed~me:~ation held one r'~eet,ng airing the year,
in Minneapolis, Minnesota, on December 28, 1939, ~ connection with the
sessions of the Geological Society of America. The main topic of dis-
cussion at this meeting was the work of the sub-co=mittees on Diager~esis
and on the Compilation of Statistical Data on Sediments. Dr. Ralph :~.
Grim of the State Geological Survey of Illinois was appointed chairman
of the Sub-co~n~q~tee on Diagenesis Ad he divas asked to recommend personnel
for the committee acid to make a prelir~i~ry survey of the problem, which
he agreed to do during the current year.
Ate the meeting of the Committee the previous year in New York
the subject of d~agenesi~; had been considered as one of the most important
questions confronting students of sedimentation, am the Committee is
particularly fortunate in having :~. G=m accept the chairmanship of the
sub-committee, because of his familiarity with clay Annuals, which are
intimately associated With diagenesis.
The tollowi:ng is Dr. Gr~m's report on the activities of the Sub-
o~ittee on Diagenesis up to :~pri~ 1, 1940:
"lye primary objectives of this sub-co~'ttee are to assemble
and to organize the data available In the literature regarding Mutagenesis,
Ad to point out promising prolix for investigation that .11 add to
our knowledge of the sub ject.
: Sin order to attain these objectives, it seemed hnoSt desirable
to organize a committee in which each member agreed to undertake to
assemble the available data for a given :field, o.g., recent marine sedi-
me:rlts, recent non-r~ar~ne sediments, etc. It ~ s plan cod that the individual
Is refill be printed separately in the report of the cor~r~ittee as
they are completed. ~ Finally the sub-co~ittee chair ~11 undertake
to organize the data so that any general principles or general problems
will be brought out*
"At the present title the sub-co~ittee is being organized and its
work is getting started. ~lthou~gk the r~orI: before the sub-cor.=ittee
hi 11 require considerable tine, it is hoped that progress can be made
and reports issued Within a reasonable theme, perhaps one year."
Dr. fir. C. Kru-=bein, of the University of Chicago, Teas appointed

Sediraents. He was also asked to recommend personnel for the so cox=.uttee
and Mae a preliminary survey of the problem. Subsequently, Messrs. W. I:.
Cogen , Shell Oil Company , HO1ASIO]:1, Texas, G. H. Otto, U. S. Soil Conser~ra-
t~on Service, Pasadena, Cal~tox~ia; and A. C. Tester, University of Iowa,
Ida City, Iowa, were appointed members of this sub-co~ittee. The first
report of the sub~co~'ttee, prepared by Dr. ~,mbein, is presented as
Exhibit ~ in the appendix of this report.
The obj ect of thi s sub-co~nm, tte,e is to assemble statist) Cal data on
mechanical anal yses and other properties of recent sediments in order to
ascertain whether or not-di:~ferent typos of sediments might be Pound to
have distinctive characte:~stics which should facilitate the interpretation
of the origin..of conso:Lidated sediments, which the geologist encounters
In field work. No such statistical study has yet been attempted and with
the vast await of quantitative data on the different properties of sedi-
ments tat has been obtained within the past f~ years, it Is possible that
meant; of identification of some kinds of sediments might be found. At any
rate, such ~ study should indicate the limits between which the different
properties of individual types of sediments Oo vary, and the ~nformatn on
obtained should fuel? the determination of the mode of? origin of sedimentary
ro eke .
The Committee at the meeting in L~;i~eapo~is, in addition to d~s-
mssing the work of these two sub-corn~n; ttees 1luanimously passed the
following resolution thanking the American Association of Petroleura
Geologists for publishing the Symposium on.Recent Urine Sediments, which
was prepared under the auspices of the Committee during the past four
years:
Whereas the American Association of Petroleum Geologists
has published the Symposium on Recent Brine Sediments, which
was compiled under the auspices of the Committee on Sedimentation,
Whereas the book leas been made available to the public at
such a moderate price, thus increasing;, its usefulness, and
Whereas the composition and made-up of the book are so
excellent,
Be it resolved that the meters of the Committee on Sedimen-
tation empress their appreciation and gratitude to the kner~car1
Association of Petroleum Geologists for publishing the Symposium
on Recent I.ldrine Sediments, aM thank the Executive Committee
of the Association for mthorizir~ the publication of the book;
the special committee, composed of Drs. K. C. Eeaid and
W. H. IV~enhofel, appointed to appraise the value of the m~u-
script, for their favorable recommendation; Professor W. A.
Ver Wiebe, Editor of the Association, for his interest and
guidance in the publical~on of the book; and especially, 3~.
J. P. D. ~11, Business Meager of the Association, for his

hearty cooperation arid untiring efforts in seeing the publica-
t~on through to cc~p~etio:a,
And be it further resolved that copies of this }resolution
be sent to the Executive C=r~ittee of the Axaer~can Association
of Petroleum Geologists, and to Mnssrs..~. C. Heald, J. P. D.
Eu11, W. B. Twanhofe1, and W. A. Ver Probe.
This symposium consists of 34 pep are by 31 authors on ditfore~o
aspects at the field of rocout merino sodas. Tho Role as pub1ishGd

the American Association of Potrol~m Geologists for 05.00 to ttO$ public

Roports of Progress
The Committee on SedinlerLtation, as in the past, has sponsored the
preparation of summary reports of progress in different fields of
interest to students of sedimentation. Four such reports are presented
as exhibits in the Appendix to the current report of the Committee, namely:
Exhibit B - Mineralogy of sedimentary rocks, lg37-3 939, by
£. J. Pettijohn.

In addition, two articles of intorost to studont.s of sod'~nentat~on
arc included. One, Exhibit :F, is on "cures for determining probable
odors in heavy mineral studies", by Gordon Rittenhouso of tho U. S. Soil
(conservation Service, This pep or is of value because the reliable
determination of probable error is of fundamontal importance 'n quantita-
tive studies of sediments. The other article, Tibia G. is on "The
~portanco of heavy r:a'noral analysis for regional sedimontary petrology",
by I). J. Dooglas of the Bataatscho Potroloum lL~atsch~ppi j ~ Tho Rogue,
Netherlands. In :~econt yours PrO[QSS~ C. H. Edo`~= rind his co-~rkors
in the Notherl&nds have paid p.art~cular attont~on to the intcrprat=tion
of rogiona1 heavy mineral studios, and it seems of interest to ~mer~.can
students of sedimentation to have an account of these studies presented
in the reports of the Committee on Sedimentation. Accordingly, Do.
Doeglas was asked to write a start article on this world for the present
report, which he kindly consantod to do.
Financial Statement

The income of the Committee on Sedimontation from April l' 1959 to
March al, 1940 seas t184.20 ~d the. expenses were $290.82. The balance on
hand on Monarch 31, 1940 divas $728~92. The excess of expenses over income
~. . _ . .

was 9;106.62, but most of the expenses of the Committee during the year
were in connection with the preparation of the Symposiums upon recent
sediments, and according to tab understanding with too Moroccan Association
of Petroleum Goolo~sts2 which published the symposium, the c~rPittoo is
to be rci~bursod for its oxpo~os in proparing the s~pos~um, as soon as
su:~iciont profit trom the salo of the book has resulted. As the sale
of the volume has been large, it is anticipated that during the coming
year it will be possible for the ~sociatio:n to reimburse the Committee
tor these expenses wit ch amount to $548.~31.
