Sum-z)ry of a report by

Two tendencies can be disi'lguished in the compilation of
survey maps:one is characterised by the drafting of rNaps to corresp:nd to
the complex problems end h:e resulted in a series of maps,of liAch the
preparation become possible durEg the process of accumulating facts and
data. During the 1 st years we succeedeY in increasing the number of
1:5,000,000 maps of the USSR which cover geologic,tectonic,neotectonic
geomorphologic731,64ent.rnery,hydrogeologic.1,megnetic anomaly,m?tallogenic
etc map.
The preparation -)f a s,ries of naps 1:5,000,000 illustrate
conveniently the geologic 1 structure of regions of the platform type and
is carried out in large areas of the country with independent geologiJA?
economic consider-tions.The geologic 1 maps of the SibeAan platform were
already shown at the Copenhagen Congress; these maps are now supplemeatOd.
with new data and can now be republished. A series of maps on this scale is
being completed for the East European (Russian) platform.
Another trend in geologic 1 mapping is the increang tendency
to reveal buried geological structures. Hew maps have appeared and the
old ones have been improved.
quite recently the compile.ion of the Litho?facies Atlas was
completed on a 1:5,')00,000 scale for the European part of the u_;,a. in
atlas on a 1:7,500,00 sc-le is being compiled for the entire territory
of the Soviet Union. It will include scores of lithological?pclaeogeograph?
ical,palaeotectonic maps etc
In other areas maps showing reservoir c'pacity,subsurfece
drainage,hydroche ical maps are being prepared. Deep drilling has necessitated
drafting maps indicating the thickness of ov,rburdentgeologic,1 structure
of folded basement rocks under the platform cover and other features due to
the development of the earth's crust?

maps which are intended for the Atlas of the ,orld. Yhe first circum-
polar geologic map of the Artic is of great interest and includes the
geologic:1 structures of North America and Greenland.
2. Tectonic Mgp
The 1:5,000,000 map of the USSR has frequently been shown at
conferences:that on a 1:10,000,000 scale has recently been prepared.
Experimental maps 1:2,500,000 are now being tried under the direction of
T.N.Spijarski.The main aim of this map is to show the particular doveloiment
and structure of ce tin regions. It shows further:structural stages,maDor
folds and faults,manatic complexes and,on the platform regions:isolines
showing the structure of typical units of the cover,isopacs of the sediments.
The map reflects the tectonics in a way as yet unachieved.
The drafting of this map resolved many of the problems of the
larger scale tectonic maps (1:1,500,000 - 1:500,000. TI,e need for these maps
is now felt for the preparation of previsional and metallogenic maps. PaPs at
this scHle can be divided into three gourps:tectonic maps,generil maps and
specialised tectonic maps.
Fhe first neo-tectonic map of Russia was published t,lo years ago
(1:5,044x-4)). Further maps,based on this latter map,eee being drafted on a
largr sc le;firstly in the oil-bearing re-ions (Turkmenia,estern Siberia etc)
They are all experimental. The analysis of neotectonic and geoporphai4icd
dLta (morphometric analysis) facilitates greatly those of seismic data.
The ordinary tectonic maps show stJ.uctures controling the
repartition of magmatic manifesttiens,depth of d positd etc. In the platform
areas, tne hypsometric position of two or more horizons an indicated by
isolines,faults and local geophysical anomalies. Special attention is paid to
structures deteemining mineral reparti'Aon and magmatic phenomena ,ehen present.
:-'he tectonic Taps of platform areas have considerable practical
laplication in the search for favourable structures for oil drilling.!hey
Like the rese voir capacity maps are indispensable for research for oil
and undergr- nd water.
Specialised maps are now being drafted for specific mineral
prospecting(bauxite,coal etc). They show essentially the tectonic relief of
the besement,its depth as well as interpreta ion of lithological and geo-
physical data.

The study of the structure of or fields has shown the necessity
of drafting large scale s ructural maps (1:25,000 and larger) which iedicate
all the fu'damental elements of f ulting,folding e:c which effect mineral
dis ribution. These maps arc still experimental and their coo:ent varies
according to the structural characteristics of the deposit:they will assist
in prospecting for hidd n or deeply buried deposits;they Lend towards .he
previsional me'allogenic maps.
The inclusion of geophvsical data on tectonic maps,enlarges their
scope and tectonic maps now er.: based on observed data.

During the 1958 Meeting of the Com ission for the Goologicel
ap of the Vforld in Paris,the US;11 had the opp rtunity of showings ome patt-rns
of small scale minrrogenic mapson which it was possible to recognise zones
of similar geologicel structure and subsequently similar ore mineralisa,,ion.
Such maps deeonstree many tiervrtant problems of regional and
general metallogeny:the polycyclic conditi-ea pertai'ing in the majortty of
geosynclinal belts and geosynclines wharacterised by prolOged multi?phase
development. The important role of met-llogenic 'isolation' of the intrusions
is stressed;that of deep fpults as regulators of the distribution of magmititee
and their acompanying ares as also endogenic doosits of mineral resources
connect-d with them.
Small sc .11 maps load to the draf ing of larg(r scale maps
where one can determinemore precisely sectors favourable for prospecting
but also forecast the type of min rel d posit end give quantative estim?
ations. In new retions,where sufficent geologic data is missing, 1:500,000
is coesidred suitable for minaragonic and previsional maps.
The requirements for draftin of minerogenic -,aps are
now known. They sut carry the main pecularides of the geologic formations
so as to show the paragenetic rela:Aons between mincralisations and certain
manifestations of tectonics,magmatism,sedimentation,metamorphism etc. The
demonstration of ppatial and genetical connections between ore deposits and
coun:ry rock is of special im-ortance. Direct as well as indirect characteristics
of deposits must be reflected on the map :i.e; results of geophysical work
geochemical and mineralogical investigations .
This general and special data may oberburden the map and render
it

illegible.Practice has shown alp.t it is necessary to compile not one,but
several mineragenic maps Aich gr-up the ores acording to their geneUc
affinity. For examnle on may is concerned ,!ith ahtimpny and mercury deposits
The maps show on sdecially selected geologic 1 background a special over?
print .::hich includes symbols for o-e doposits and their manifestations.
Reservoir capacity,papaeogranhical etc informa-ion can be add d according to
the ores concerned.
Conventi-hlal symbols mu'A be car and easily remembered.
E.T.3hatzalov has sug.;ested a retiv:r detailed system v!hich h s been successfully
applied for mineragenic maps.
These maps gener1111: show,according to the total sum of inform?
ation available:
a) known depesits,their extent and concentration.
b) areas characteAsed by economic deposits and possible occurrence of
industrial d -posits.
c) areas favourable for prospection.
c) areas of possible occurrence of deposits
Qualitative classification of areas acordin:4 to probable
economic value only reflects the initial stage of prognostication
Experimental work on these paps is only starting,but they are the base for
every day and planning of prosppction.
