In looking back at the 1970's, the decade may prove to be a crucial
one in the development of quantitative geology. After
quantification had lain fallow and essen- tially undeveloped for
120 years, introduction of the computer in the 1950's revived
interest and fostered ad- vances in the subject. Developments
continued through the 1960's at a rapid pace and the
state-of-the-art was reported on in the proceedings of an
international sym- posium held at the University of Kansas in June
1969 (Merriam, 1969). The proceedings of the Kansas meeting,
published as the first contribution in this series on "Computer
Applications in the Earth Sciences" was one of 8 collo- quia
sponsored by the Kansas Geological Survey and the International
Association for Mathematical Geology in the late 1960's. In a sense
those international sympo- sia were continued in the 1970's at
Syracuse University as a series of Geochautauquas sponsored by the
Depart- ment of Geology at Syracuse University and the Interna-
tional Association for Mathematical Geology. These pro- ceedings
report the results of the 8th Geochautauqua held in Syracuse on
26-27 October 1979.
Modeling and simulation were introduced to the earth sciences about
four decades ago. Modeling has proven its worth and now it is an
accepted procedure for analyzing and solving geological problems.
The papers in this collection are focused on modeling sediment
deposition and sedimentary sequences and have a decidedly practical
flavor. Some of the leading simulation packages, such as
CORRELATOR, SEDFLUX, SEDpak, SEDSIM, STRATA, and STRATSIM are
applied to problems in hydrocarbon exploration, oil production,
groundwater development, coal-bed appraisal, geothermics, and
environmental diagnosis. All of these subjects fall under the broad
heading of sedimentary basin analysis. The fifteen papers in this
volume are written by internationally recognized experts from
academia and industry. The contributions represent the status of
geologic modeling and simulation at the start of the 21st century,
and will give the reader an insight into current research problems
and their possible solutions.
Geothermics in Basin Analysis focuses on the study of sedimentary
basins, stressing essential parts of problems in which geothermics
is involved. Subject matter includes the measuring of temperature
logs and capturing of industrial temperature data and their
interpretation to delineate subsurface conditions and processes,
the importance of porosity and pore filling for modeling thermal
fields, the thermal insulation of shales, geothermal anomalies
associated with mud diapirs and basin hydrodynamic regimes,
temperatures related to magmatic underplating and plate tectonics.
This symposium on 'Computerized Basin Analysis for Prognosis of
Energy - and Mineral Resources' was organized by Dr. Jan Harff,
chairman ofthe Scientific Committee for the meeting, in Giistrowin
what was then East Germany. Sponsors ofthis meeting were the
International Union of Geological Sciences' Commission on Storage,
Automatic Pro cessing and Retrieval of Geologic Data (COGEODATA),
Academy of Sciences of the German Democratic Republic (GDR),
National Oil and Gas Trustofthe GDR, and the International
Association for Mathematical Geology (IAMG). Main topics of the
symposium, held from 19-22 June 1990, were application of computer
methods to the exploration and exploitation of oil and gas, coal,
and other energy and mineral resources. There were computer
demonstrations as well as a one-day field trip to the geothermic
heating plant in Waren. The Regional Group for Eastern Europe of
COG EO DATA also met during the conference. Fifty-one papers were
presented including eight poster sessions by authors from 14
countries. As was to be expected, there was a large percentage of
papers from the East Bloc of European countries, especially the
GDR, USSR, and the CSSR with a fair representation from the FRG and
USA and a smattering from the nine others. Most of the papers were
application oriented and related to the mineral industries. There
was ample time for exchange of ideas and dissemination of material.
This volume is a compendium of papers on the subject, as noted in
the book title, of modeling and mapping. They were presented at the
25th Anniversary meeting of the International Association for
Mathematical Geology (IAMG) at Praha (Prague), Czech Republic in
October of 1993. The Association, founded at the International
Geological Congress (IGC) in Prague in 1968, returned to its
origins for its Silver Anniversary celebration. All in all 146
papers by 276 authors were offered for the 165 attendees at the
3-day meeting convened in the Hotel Krystal. It was a time for
remembrance and for future prognostication. The selected papers in
Geologic Modeling and Mapping comprise a broad range of powerful
techniques used nowadays in the earth sciences. Modeling stands for
reconstruction of geological features, such as subsurface
structure, in space and time, as well as for simulation of
geological processes both providing scenarios of geologic events
and how these events might have occurred. Mapping stands for
spatial analysis of data, a topic that always has been an extremely
important part of the earth sciences. Because both modeling and
mapping are used widely in conjunction, the book title should
reflect the close relation of the subjects rather than a division.
Here, we bring together a collection of papers that hopefully
contribute to the growing amount of knowledge on these techniques.

This volume 'Use ofMicrocomputers in Geology' is the sixth in the
series Computer Applications in the Earth Sciences published by
Plenum Press in New York. The series was started in 1969 to publish
proceedings of important meetings on geomathematics and computer
applications. The first two volumes recorded proceedings ofthe
Colloquia (1969,1970) sponsored by the Kansas Geological Survey at
The University ofKansas in Lawrence. The third volume was
proceedings ofthe 8th International Sedimentological Congress
(1971) held in Heidelberg, West Germany; the fourth was preceedings
ofthe 8th Geochautauqua (1979) at Syracuse Universityin Syracuse,
New York; and the fifth was selected papers from the 27th
International Geological Congress (1989) held in Washington, D.C.
All meetings were cosponsored by the International Association for
Mathematical Geology. These special publications are important in
the development of quantitative geology. Papers by a wide range of
authors on a wide range of topics gives the reader a flavor for
recent advances in the subject -in this volume, those advances in
the use ofmicrocomputers. The 24 authors ofthe 15 papers come from
nine countries -Australia, Austria, Canada, France, Italy,
Portugal, Switzerland, UK, and USA. My coeditor, Hans Kurzl, has
given pertinent information on the included papers in the
Introduction."
The International Association for Mathematical Geology, in conjunc
tion with the International Geological Congress, sponsored two
symposia in Montreal, Canada, September 1972. The first symposium,
Random Processes in Geology, consisted of two, half-day sessions
and featured ten major papers on various aspects of stochastic
models as applied to geologic problems. The invited speakers were
selected by the Projects Committee of the IAMG so as to represent a
wide spectrum of geologic disciplines. The topics fell naturally
into two categories: those dealing with continuous stochastic
processes and those concerned with point processes and branch ing
operations. The program, as presented, was Introduction: R. A.
Reyment Ideal granites and their metasomatic transformation:
stochastic model, statistical description, and natural rocks: A. B.
Vistelius (read by G. Lea) The influence of greisenization on the
Markovian properties of grain sequences in granitic rocks: M. A.
Romanova The mechanism of bed formation in a limestone-shale
environment: W. Schwarzacher Volcanic eruptions as random events:
F. E. Wickman Statistical geometric similarity in drainage
networks: J. S. Smart Length and gradient properties of stochastic
streams: M. F. Dacey Application of stochastic point processes to
volcanic eruptions: R. A. Reyment Applications of random process
models to the description of spatial distributions of qualitative
geologic variables: P. Switzer Sedimentary porous materials as a
realization of a stochastic process: F. W. Preston and J. C. Davis
Stochastic process models in geology: W. C. Krumbein. This volume
consists of eight of the ten presented papers."
