Abstract A satisfactory tectonic-magmatic-metallogenic
correlation in the East Iran, Middle East for Alpine time was
revealed in the region (mainly metallogeny – led by
outstanding regional trio: Drs. E. Romanko, A.
Houshmand-Zadeh, and M.A.A. Nogol Sadat). Geological
northeastern zonation and “hot” tectonics due to the African
superplume activity including probably slab delamination is
revealed too. Strongly dominated rocks of calc-alkaline and
shoshonite series deal with a known subduction of Arabian
plate beneath the Central Iran block. Intraplate African
superplume-related rocks are subalkaline – alkaline ones
including Quaternary carbonatites in Hanneshin,
Afghanistan. Tectonic-magmatic pair could be postulated
here. General oil / hydrocarbons (HC) productivity
decreasing to the north could be in an agreement with
corresponding decreasing of African superplume activity too.
Regional economic Cu-Au etc. metallogeny is mainly
stipulated by a subduction mentioned.

1. Introduction
Middle East is geologically, economically… exclusively
interesting region, however, very irregular studied. Great
importance of its regional study is obvious. Metallogeny and
geology of poorly studied East Iran close a very impressive
Alpine - Himalayan structures junction (Khain, 2001; Khain,
Leonov 1988; E. Romanko et al, 1984; Houshandzadeh et al.,
1986; Imamverdiyev, 2000; Stocklin et al., 1965;
Milanovsky, Koronovsky, 1973; Abdullah et al, 1980; etc.,
Fig. 1) recently studied under the leadership of outstanding
trio – known regional specialists Drs. E. Romanko, A.
Houshmandzadeh, and M. A. A. Nogol Sadat.
2. Methodology
Methodology of our research includes traditional general
geological investigations including field works etc., then
also special ones, and joint analysis of all materials available
since known works led by Dr E. Romanko (E. Romanko,
1984) etc.
3. Results
We present new data on magmatic rocks of the region
studied: dominated Paleocene – Quaternary
subduction-related calc-alkaline rocks and, rare, Eocene –
Oligocene shoshonitic-latitic rocks (first group) and
principally other subordinate rocks younger Neogene –
Quaternary intraplate subalkaline and rarely - alkaline ones
(second group).
Rocks of the first group (subduction-related differentiated
calc-alkaline rocks: basalts - dominated andesites - rhyolites,
granodiorites, etc.) are the products of a large subduction of
the Tethys lithosphere and Arabian plate beneath the Central
Iran block or microplate (Fig. 1).
This process is confirmed by the regional tectonic analysis,
tomography by known J. Ritsema’s team (Bull et al., 2009
etc.) and petrology and geochemistry (Imamverdiyev, 2000;
Romanko et al., 2012; etc., Figure 1). Catastrophic
earthquakes of ca. 8 M and more on the Richter scale,
unfortunately, are not rare here. A recent catastrophic
