# Concepts and Problems for Synthesis of Metallogenic Belts

Metallogenic belts are characterized by a narrow age of formation, and
include districts, deposits, and occurrences. The metallogenic belts are
synthesized and described for the main structural units of the North
Asian Craton and Sino-Korean Craton, framing orogenic belts that consist
of collage of accreted tectonostratigraphic terranes, younger overlap
volcanic and sedimentary rock sequences, and younger stitching plutonic
sequences. The major units in the region are the North Asian Craton,
exterior passive continental margin units (Baikal-Patom, Enisey Ridge,
Southern Taymir, and Verkhoyansk passive continental margin units), the
early Paleozoic Central Asian orogenic belt, and various Mesozoic and
Cenozoic continental margin arcs. Metallogenic belts are interpreted
according to specific geodynamic environments including cratonal, active
and passive continental margin, continental-margin arc, island arc,
oceanic or continental rift, collisional, transform-continental margin,
and impact.

Previous metallogenic units published by various authors for studies of
metallogenic zonation include (Bilibin, 1955; Itsikson and others, 1965;
Shatalov, 1965; Itsikson, 1973, 1979; Guild, 1978; Scheglov, 1980;
Mitchell and Garson, 1981; Radkevich, 1982; Tomson, 1988; Zonenshain and
others, 1992; Koroteev, 1996; Parfenov and others, 1999; Sukhov and
others, 2000; Plyuschev, 2001): (1) planetary deposit-hosting province
or planetary metallogenic belt (≥1000 by 10^3^ km^2^); (2)
deposit-hosting belt or metallogenic belt (150 to 1000 by 10^3^ km^2^);
(3) deposit-hosting system or metallogenic system (40 to 150 by 10^3^
km^2^); (4) deposit-hosting zone or metallogenic zone (20 to 40 by 10^3^
km^2^); (5) deposit-hosting subzone or metallogenic subzone (2 to 20 by
10^3^ km^2^); and (6) ore district (0.4 to 2.0 by 10^3^ km^2^).

However, often determination of differences between some of these
metallogenic units is difficult. Examples are metallogenic system versus
metallogenic zone, or ore district versus deposit-hosting subzone. For
this study, only a two simple terms are employed: metallogenic belt and
contained district. Generally, the size of metallogenic belts is partly
a function of the scale of the analysis. For this study, metallogenic
belts are synthesized and compiled at 5 M scale.

In this study, a metallogenic belt is similar to a group of *mineral
resource tract* as originally defined by Pratt (1981) and used for
assessment of mineral resource potential in the USA, as in exemplified
in Luddington and Cox (1996). The metallogenic belt maps and underlying
regional geologic (terrane and overlap assemblage maps) constitute a
basic part of the three-part methodology of quantitative mineral
resource assessment as described by Cox (1993) and Singer (1993, 1994).

The following concepts are employed for the synthesis of metallogenic
belts.

*Mineral Deposit Association.* Each mineral resource tract (or
metallogenic belt) includes a single mineral deposit type or a group of
coeval, closely-located and genetically-related mineral deposits types.

*Geodynamic Event for Deposit Formation.* Each metallogenic belt
contains a group of coeval and genetically related deposits that were
formed in a specific geodynamic event. Examples are collision,
continental-margin arc, accretion, rifting, and others.

*Favorable Geological Environment.* Each metallogenic belt is underlain
by a geological host rock and (or) structure that is favorable for a
particular suite of mineral deposit types.

*Tectonic or Geological Boundaries.* Each mineral resource tract (or
metallogenic belt) is usually bounded by favorable either stratigraphic
or magmatic units, or by major faults (sutures) along which substantial
translations have occurred.

*Relation of Features of Metallogenic Belt to Host Unit.* The name,
boundaries, and inner composition of each metallogenic belt corresponds
to previously define characteristics of rocks or structures hosting the
deposits, and to a suite of characteristics for the group of deposits
and host rocks.

With these definitions and principles, the area defined for a
metallogenic belt is predictive or prognostic for undiscovered deposits.
Consequently, the synthesis and compilation of metallogenic belts is a
powerful tool for mineral exploration, land-use planning, and
environmental studies.

For modern metallogenic analysis, three interrelated problems exist.

\(1\) What is the relation of geodynamics to regional or global
metallogeny? As discussed by Zonenshain and others (1992) and Dobretsov
and Kirdyashkin (1994), this problem includes the role of convective
processes in mantle and mantle plumes, the global processes of formation
of the continents and oceans, the dynamics of development of major
tectonic units of the earth\'s crust, metallogenic evolution of the
earth, and the role mantle processes in the origin of major-belts of
deposits.

\(2\) What is relation of regional metallogeny to individual lithosphere
blocks? As discussed by Guild (1978), Mitchell and Garson (1981), and
Koroteev (1996), this problem includes the genesis of specific
metallogenic belts as a function of specific geodynamic environments
using the modem concepts of plate tectonics.

And (3) what is the relation of metallogeny to individual
tectonostratigraphic terranes and overlap assemblages? As discussed by
Nokleberg and others (1993, 1998) and Parfenov and others (1999), this
problem includes the genesis of specific metallogenic belts in
individual fault-bounded units of distinctive stratigraphy, defined as
tectonostratigraphic terranes, and in younger overlapping assemblages
often containing igneous rocks formed in continental margin or island
arcs, along rift systems in continents, or along transform continental
margins.

# Methodology of Metallogenic Analysis, Key Definitions, Geologic Time Scale, and Time Spans

## Methodology of Metallogenic and 

## Tectonic Analysis

The compilation, synthesis, description, and interpretation of
metallogenic belts of Northeast Asia is part of a intricate process to
analyze the complex metallogenic and tectonic history of the region. The
methodology for this type of analysis of consists of the following
steps. (1) The major lode deposits are described and classified
according to defined mineral deposit models. (2) Metallogenic belts are
delineated. (3) Tectonic environments for the cratons, craton margins,
orogenic collages of terranes, overlap assemblages, and contained
metallogenic belts are assigned from regional compilation and synthesis
of stratigraphic, structural, metamorphic, isotopic, faunal, and
provenance data. The tectonic environments include cratonal, passive
continental margin, metamorphosed continental margin, continental-margin
arc, island arc, transform continental-margin arc, oceanic crust,
seamount, ophiolite, accretionary wedge, subduction zone, turbidite
basin, and metamorphic. (4) Correlations are made between terranes,
fragments of overlap assemblages, and fragments of contained
metallogenic belts. (5) Coeval terranes and their contained metallogenic
belts are grouped into a single metallogenic and tectonic origin, for
instance, a single island arc or subduction zone. (6) Igneous-arc and
subduction-zone terranes, which are interpreted as being tectonically
linked, and their contained metallogenic belts, are grouped into coeval,
curvilinear arc-subduction-zone-complexes. (7) By use of geologic,
faunal, and paleomagnetic data, the original positions of terranes and
their metallogenic belts are interpreted. (8) The paths of tectonic
migration of terranes and contained metallogenic belts are constructed.
(9) The timings and nature of accretions of terranes and contained
metallogenic belts are determined from geologic, age, and structural
data; (10) The nature of collision-related geologic units and their
contained metallogenic belts are determined from geologic data. And (11)
the nature and timing of post-accretionary overlap assemblages and
contained metallogenic belts are determined from geologic and age data.

## Key Metallogenic and Tectonic Definitions

For the compilation, synthesis, description, and interpretation of
metallogenic belts, the following and mineral deposit, metallogenic, and
tectonic definitions are employed. The definitions are adapted from
Coney and others (1980), Jones and others (1983), Howell and others
(1985), Monger and Berg (1987), Nokleberg and others (1994a, b, 2001),
Wheeler and others (1988), and Scotese and others (2001).

*Accretion*. Tectonic juxtaposition of two or more terranes, or tectonic
juxtaposition of terranes to a craton margin. Accretion of terranes to
one another or to a craton margin also defines a major change in the
tectonic evolution of terranes and craton margins.

*Accretionary wedge and subduction-zone terrane*. Fragment of a mildly
to intensely deformed complex consisting of varying amounts of turbidite
deposits, continental-margin rocks, oceanic crust and overlying units,
and oceanic mantle. Divided into units composed predominantly of
turbidite deposits or predominantly of oceanic rocks. Units are
interpreted to have formed during tectonic juxtaposition in a zone of
major thrusting of one lithosphere plate beneath another, generally in
zones of thrusting along the margin of a continent or an island arc. May
include large fault-bounded units with a coherent stratigraphy. Many
subduction-zone terranes contain fragments of oceanic crust and
associated rocks that exhibit a complex structural history, occur in a
major thrust zone, and possess blueschist-facies metamorphism.

*Collage of terranes.* Groups of tectonostratigraphic terranes,
generally in oceanic areas, for which insufficient data exist to
separate units.

*Craton.* Chiefly regionally metamorphosed and deformed shield
assemblages of Archean and Early Proterozoic sedimentary, volcanic, and
plutonic rocks, and overlying platform successions of Late Proterozoic,
Paleozoic, and local Mesozoic and Cenozoic sedimentary and lesser
volcanic rocks.

*Craton margin.* Chiefly Late Proterozoic through Jurassic sedimentary
rocks deposited on a continental shelf or slope. Consists mainly of
platform successions. Locally has, or may have had an Archean and Early
Proterozoic cratonal basement.

*Cratonal terrane*. Fragment of a craton.

*Continental-margin arc terrane*. Fragment of an igneous belt of coeval
plutonic and volcanic rocks, and associated sedimentary rocks that
formed above a subduction zone dipping beneath a continent. Inferred to
possess a sialic basement.

*Deposit*. A general term for any lode or placer mineral occurrence,
mineral deposit, prospect, and (or) mine.

*Island-arc terrane.* Fragment of an igneous belt of plutonic rocks,
coeval volcanic rocks, and associated sedimentary rocks that formed
above an oceanic subduction zone. Inferred to possess a simatic
basement.

*Metallogenic belt*. A geologic unit (area) that either contains or is
favorable for a group of coeval and genetically-related, significant
lode and placer deposit models. With this definition, a metallogenic
belt is a predictive for undiscovered deposits.

*Metamorphic terrane.* Fragment of a highly metamorphosed or deformed
assemblage of sedimentary, volcanic, or plutonic rocks that cannot be
assigned to a single tectonic environment because the original
stratigraphy and structure are obscured. Includes intensely-deformed
structural melanges that contain intensely-deformed fragments of two or
more terranes.

*Metamorphosed continental margin terrane.* Fragment of a passive
continental margin, in places moderately to highly metamorphosed and
deformed, that cannot be linked with certainty to the nearby craton
margin. May be derived either from a nearby craton margin or from a
distant site.

*Mine*. A site where valuable minerals have been extracted.

*Mineral deposit*. A site where concentrations of potentially valuable
minerals for which grade and tonnage estimates have been made.

*Mineral occurrence.* A site of potentially valuable minerals on which
no visible exploration has occurred, or for which no grade and tonnage
estimates have been made.

*Oceanic crust, seamount, and ophiolite terrane*. Fragment of part or
all of a suite of *eugeoclinal* deep-marine sedimentary rocks, pillow
basalt, gabbro, and ultramafic rocks that are interpreted as oceanic
sedimentary and volcanic rocks and the upper mantle. Includes both
inferred offshore oceanic and marginal ocean basin rocks, minor
volcaniclastic rocks of magmatic arc derivation, and major marine
volcanic accumulations formed at a hotspot, fracture zone, or spreading
axis.

*Overlap assemblage.* A postaccretion unit of sedimentary or igneous
rocks deposited on, or intruded into, two or more adjacent terranes. The
sedimentary and volcanic parts either depositionally overlie, or are
interpreted to have originally depositionally overlain, two or more
adjacent terranes, or terranes and the craton margin. Overlapping
plutonic rocks, which may be coeval and genetically related to overlap
volcanic rocks, link or stitch together adjacent terranes, or a terrane
and a craton margin.

Passive continental margin terrane. Fragment of a craton margin.

*Post-accretion rock unit.* Suite of sedimentary, volcanic, or plutonic
rocks that formed in the late history of a terrane, after accretion. May
occur also on adjacent terranes or on the craton margin either as an
overlap assemblage or as a basinal deposit. A relative-time term
denoting rocks formed after tectonic juxtaposition of one terrane to an
adjacent terrane.

*Pre-accretion rock unit.* Suite of sedimentary, volcanic, or plutonic
rocks that formed in the early history of a terrane, before accretion.
Constitutes the stratigraphy and igneous geology inherent to a terrane.
A relative-time term denoting rocks formed before tectonic juxtaposition
of one terrane to an adjacent terrane.

*Prospect*. A site of potentially valuable minerals in which excavation
has occurred.

*Significant mineral deposit*. A mine, mineral deposit, prospect, or
occurrence that is judged as important for the metallogenesis of a
geographic region.

*Subterrane.* A fault-bounded unit within a terrane that exhibit
similar, but not identical geologic history relative to another fault
bounded unit in the same terrane.

*Superterrane.* An aggregate of terranes that is interpreted to share
either a similar stratigraphic kindred or affinity, or a common geologic
history after accretion (Moore, 1992). An approximate synonym is
*composite terrane*.

*Tectonic linkage.* The interpreted association of a suite of coeval
tectonic units that formed in the same region and as the result of the
same tectonic processes. An example is the linking of a coeval
continental-margin arc, forearc deposits, a back-arc rift assemblage,
and a subduction-zone complex, all related to the underthrusting of a
continental margin by oceanic crust.

*Tectonostratigraphic terrane.* A fault-bounded geologic entity or
fragment that is characterized by a distinctive geologic history that
differs markedly from that of adjacent terranes (Jones and others, 1983;
Howell and others, 1985).

*Transform continental-margin arc*. An igneous belt of coeval plutonic
and volcanic rocks, and associated sedimentary rocks that formed along a
transform fault that occurs along the margin of a craton, passive
continental margin, and (or) collage of terranes accreted to a
continental margin.

*Turbidite basin terrane.* Fragment of a basin filled with deep-marine
clastic deposits in either an orogenic forearc or backarc setting. May
include continental-slope and continental-rise turbidite deposits, and
submarine-fan turbidite deposits deposited on oceanic crust. May include
minor epiclastic and volcaniclastic deposits.

## Geologic Time Scale and Time Spans

Geologic time scale units are according to the IUGS Global Stratigraphic
Chart (Remane, 1998). For this study, for some descriptions of
metallogenic belt and geologic units, the term *Riphean* is used for the
Mesoproterozoic through Middle Neoproterozoic (1600 to 650 Ma), and the
term *Vendian* is used for Neoproterozoic III (650 to 540 Ma).

According to the main geodynamic events and the major deposit-forming
and metallogenic belt-forming events for Northeast Asia, the following
twelve time spans are used for groupings of metallogenic belts.

Archean (\> 2500 Ma)

Paleoproterozoic (2500 to 1600 Ma)

Mesoproterozoic (1600 to 1000 Ma)

Neoproterozoic (1000 to 540 Ma)

Cambrian through Silurian (540 to 410 Ma)

Devonian through Early Carboniferous (Mississippian) (410 to 320 Ma)

Late Carboniferous (Pennsylvanian) through Middle Triassic (320 to 230
Ma)

Late Triassic through Early Jurassic (230 to 175 Ma)

Middle Jurassic through Early Cretaceous (175 to 96 Ma)

Cenomanian through Campanian (96 to 72 Ma)

Maastrichnian through Oligocene (72 to 24 Ma)

Miocene through Quaternary (24 to 0 Ma)

# Mineral Deposit Models 

For descriptions of metallogenic belts, lode mineral deposits are
classified into various models or types. Detailed descriptions are
provided in the companion paper by Obolenskiy and others (2003). The
following three main principles are employed for synthesis of mineral
deposit models for this study. (1) Deposit forming processes are close
related to rock forming processes (Obruchev, 1928) and mineral deposits
originate as the result of mineral mass differentiation under their
constant circulation in sedimentary, magmatic, and metamorphic circles
of formation of rocks and geological structures (Smirnov, 1969). (2) The
classification must be as more comfortable and understandable for
appropriate user as possible. And (3) the classification must be open so
that new types of the deposits can be added in the future (Cox and
Singer, 1986).

In this classification for this study, lode deposits are grouped into
the hierarchic levels of metallogenic taxons according to such their
stable features as: (a) environment of formation of host and
genetically-related rocks, (b) genetic features of the deposit, and (c)
mineral and (or) elemental composition of the ore. The six hierarchial
levels are as follows.

Group of deposits

Class of deposits

Clan of deposits

Deposit types (models)

The deposit models are subdivided into the following four large groups
according to major geological rock-forming processes (Table 1): (1)
deposits related to magmatic processes; (2) deposits related to
hydrothermal-sedimentary processes; (3) deposits related to metamorphic
processes; (4) deposits related to surficial processes and (6) exotic
deposits. Each group includes several classes. For example, the group of
deposits related to magmatic processes includes two classes: (1) those
related to intrusive rocks; and (2) those related to extrusive rocks.
Each class includes several clans, and so on. The most detailed
subdivisions are for magmatic-related deposits because they are the most
abundant in the project area. In the below classification, lode deposit
types models that share a similar origin, such as magnesian and (or)
calcic skarns, or porphyry deposits, are grouped together under a single
genus with several types (or species) within the genus.

Some of the below deposit models differ from cited descriptions. For
example, the Bayan Obo type was described previously as a
carbonatite-related deposit. However, modern isotopic, mineralogical,
and geological data recently obtained by Chinese geologists have
resulted in a new interpretation of the deposit origin. These new data
indicate that the deposit consists of ores that formed during
Mesoproterozoic sedimentary-exhalative process, and along with coeval
metasomatic activity, sedimentary diagenesis of dolomite, and
alteration. The sedimentary-exhalative process consisted of both
sedimentation and metasomatism. Later deformation, especially during the
Caledonian orogeny, further enriched the ore. Consequently, the Bayan
Obo deposit type is herein described as related to
sedimentary-exhalative processes, not to magmatic processes. However,
magmatic processes also played an important role in deposit formation.
Consequently, this deposit model is part of the family of polygenetic
carbonate-hosted deposits. Similar revisions are made for
carbonate-hosted Hg-Sb and other deposit models.
