of its minerals and rocks. In the present study, mineralogy and geology act as x- and y-coordinates of a
classification chart of mineral resources called the “chessboard” (or “spreadsheet”) classification scheme.

spreadsheet Further information on the various types of mineral deposits, as to the major ore and gangue minerals, the
current models and the mode of formation or when and in which geodynamic setting these deposits mainly
formed throughout the geological past may be obtained from the text by simply using the code of each
deposit in the chart. This code can be created by combining the commodity (lines) shown by numbers plus
lower caps with the host rocks or structure (columns) given by capital letters.
Each commodity has a small preface on the mineralogy and chemistry and ends up with an outlook into its
final use and the supply situation of the raw material on a global basis, which may be updated by the user
through a direct link to databases available on the internet. In this case the study has been linked to the
commodity database of the US Geological Survey. The internal subdivision of each commodity section
corresponds to the common host rock lithologies (magmatic, sedimentary, and metamorphic) and
structures. Cross sections and images illustrate the common ore types of each commodity. Ore takes
priority over the mineral. The minerals and host rocks are listed by their chemical and mineralogical
compositions, respectively, separated from the text but supplemented with cross-references to the columns
and lines, where they prevalently occur.
A metallogenetic-geodynamic overview is given at the bottom of each column in the spreadsheet. It may be
taken as the “sum” or the “ mean” of a number of geodynamic models and ideas put forward by the various
researchers for all the deposits pertaining to a certain clan of lithology or structure. This classical or
conservative view of metallotects related to the common plate tectonic settings is supplemented by an
approach taken for the first time for such a number of deposits, using the concepts of sequence stratigraphy.
This paper, so as to say, is a “launch pad” for a new mindset in metallogenesis rather than the final result.
The relationship supergene–hypogene and syngenetic–epigenetic has been the topic of many studies for ages
but to keep them as separate entities is often unworkable in practice, especially in the so-called epithermal
or near-surface/shallow deposits. Vein-type and stratiform ore bodies are generally handled also very
differently. To get these different structural elements (space) and various mineralizing processes (time)
together and to allow for a forward modeling in mineral exploration, architectural elements of sequence
stratigraphy are adapted to mineral resources. Deposits are geological bodies which need accommodation
space created by the environment of formation and the tectonic/geodynamic setting through time. They are
controlled by horizontal to subhorizontal reference planes and/or vertical structures. Prerequisites for the
deposits to evolve are thermal and/or mechanical gradients. Thermal energy is for most of the settings under
consideration deeply rooted in the mantle. A perspective on how this concept might work is given in the text

by a pilot project on mineral deposits in Central Europe and in the spreadsheet classification scheme by
providing a color-coded categorization into
1. mineralization mainly related to planar architectural elements, e.g. sequence boundaries subaerial and
unconformities
2. mineralization mainly related to planar architectural elements, e.g. sequence boundaries submarine,
transgressive surfaces and maximum flooding zones/surfaces)
3. mineralization mainly controlled by system tracts (lowstand system tracts transgressive system tracts,
highstand system tracts)
4. mineralization of subvolcanic or intermediate level to be correlated with the architectural elements of
basin evolution
5. mineralization of deep level to be correlated with the deep-seated structural elements.
There are several squares on the chessboard left blank mainly for lack of information on sequence stratigraphy
of mineral deposits. This method has not found many users yet in mineral exploration. This review is designed
as an “interactive paper” open, for amendments in the electronic spreadsheet version and adjustable to the
needs and wants of application, research and training in geosciences. Metamorphic host rock lithologies and
commodities are addressed by different color codes in the chessboard classification scheme.

2.3.2. Industrial minerals and rocks

Which raw material plays the most important part in the supply-
and-demand relation of societies across the world? Some may assume
that a mineral of the group of high-unit-value commodities such as
diamond is the most significant raw material, others may rate up fossil
fuels. To be more precise, diamond is a concentrate of diamond ore. If
commodities are ranked by cumulative production values, construc-
tion raw materials occupy the top places. Aggregates, sand and gravel
are followed by quarry and dimension stones (Prentice, 1990; Lorenz,
1991). These raw materials are high-place-value commodities and the
leading members among the non-metallic raw material and industrial
minerals. It is the distance between the place of exploitation and the
place of final use which plays a crucial part when calculating the price
for the consumer. Other important non-metallic raw materials such as
rock salt, phosphates or carbonate minerals are very well known in
our daily life. Non-metallic minerals such as wollastonite, barite or
fluorite are less well-known. Non-metallic raw materials are minerals
(wollastonite) and rocks (limestones) exploited for their physical and
chemical properties (density, inertness, and insulating capacity). They
are utilized either directly (sand as extracted in the sandpit) or after
undergoing special treatments and appropriate processing in various
production processes (e.g. burning bricks). These raw materials are
neither used for the extraction of metals (see galena used to recover
lead) nor as fossil fuels (see uraninite considered as an energy source
Fig. 01.01b. Legend. in power plants). Some experts expand this comprehensive term to
include artificial products such as fly ash, smelter slags or recycled gemstones to be of outstanding aesthetic quality. To achieve this
