fulltext ������������� �� !"# $ %& '( )�& �*�* �2� +,� �-.�,/�0 ��. ��� �1��, ��0. 0� 0���,� ��� ����� �� The central part of the Ukrainian shield, where the Kirovograd ore district is located, has been the subject of prolonged investigation of the Institute of Geophysics in cooperation with another research Institutions. Around 20 years ago, A. V. Chekunov et al. (1989) proposed a geodynamic model of this territory, derived from geophysical and geological data. The model is illustrated by the geotraverse VIII Odessa — Krivoy Rog, which intersects the Kiro- vograd (now Ingulets) lithospheric block and adja- cent protogeosynclines (Fig. 1). The Kirovograd block is distinguished from them in seismic veloci- ties in crust and at the Moho discontinuity and in thickness of the crust (35—38 km against 54— 58 km). The block is cut by steep faults and gentle tectonic zones which extend into upper mantle. The suggested model explained these phenomena by the continuous development of a mantle plume or a protoasthenolite, which originated at the beginning of Early Proterozoic, influenced the deposition of the ingulo-ingulets series and caused the emplace- ment of granites, anorthosites and rapakivi granites in crust at the mature stage. The current study of deep structure of the Kiro- vograd ore district [Starostenko et al., 2010], is based on the correlation of geological and seismic data, using modern technologies, and accounts for Deep structure and geodynamics of the Kirovograd ore district (Ukranian Shield): correlation of geological and seismic data V. Starostenko1, V. Kazansky2, G. Drogitskaya1, N. Popov1, A. Tripolsky1, 2010 1 Institute of Geophysics, National Academy of Sciences of Ukraine, Kiev, Ukraine earth@igph.kiev.ru 2Institute of Geology of Ore Deposits, Petrography, Mineralogy and Geochemistry, RAS, Moscow, Russia director@igem.ru new isotopic dating [Shcherbak et al., 2008]. The study proceeds from a broad interpretation of space boundaries of the Kirovograd polymetal ore district and the incorporation of uranium, lithium, gold and titanium deposits in these boundaries (Fig. 2). The study indicates that in the Kirovograd ore district, the Paleoproterozoic magmatism started after deposition of the ingulo-ingulets series and developed in two short-lived (30—40 Ma) stages. During the first stage (2.06—2.02 Ga), the crustal Novoukrainsk-Kirovograd granitoid massif formed. During the second stage (1.75—1.72 Ga), the man- tle-derived Korsun’-Novomirgorod rapakivi-anor- thosite massif originated. In conjunction, they con- stitute the Novoukrainsk-Korsun’-Novomirgorod plu- ton which defines the surface structural pattern of the ore district. Lithium, uranium and gold deposits are located in the Novoukrainsk-Kirovograd granitoid massif and the connected Kirovograd and Zvenigorod fault zones [Bakarzhiev et al., 2005]. Lithium deposits are close in age (2.0 Ga) to the Novoukrainsk-Kirovograd massif and associated with local granite-migmatite domes. Uranium deposits are dated at 1.8 Ga, over- printed on the massif and controlled by its rejuve- nated structural elements. Gold deposit’s age is unclear. In combination, the deposits outline a wide ������� ��� ����� ���� �22 ������������� �� !"# $ %& '( )�& �*�* (30—35 km) longitudinal band going in parallel to the Subbotin-Moshorin fault zone and across the Novoukrainsk-Korsun’-Novomirgorod pluton. It was previously assumed that within the latitudinal band, the uranium deposits and host rocks had been sub- sided by east-west faults that preserved them from erosion [Genetic …, 1995]. Nowadays the band is related to a deep sublatitudinal trough in the Moho discontinuity relief (Fig. 3). The discovery is the first to establish the spatial association of Paleopro- terozoic hydrothermal ore deposits with a middle- scale anomaly of the crust-mantle boundary [Sta- rostenko et al., 2007]. The Korsun’-Novomirgorod rapakivi-anorthosite massif is devoid of Li, U, Au deposits and contains titanium mineralization of magmatic origin. Where- Fig. 1.

Projection of ore deposits on the Moho discontinuity relief (depth isolines in km): 1—3 — ore deposits (1 — lithium, 2 — uranium, 3 — gold); 4 — DSS profiles. as the Novoukrainsk-Kirovograd massif and the in- gulo-ingulets series build up an intrusive-ultrameta- morphic basement of the district, the autonomous Korsun’-Novomirgorod massif is inserted in the basement. By seismic methods, the first is traced to a depth of 15—20 km, the second to a depth of 40—50 km, that is below the Moho boundary (Fig. 4). Against this background seismic anoma- lies are interrupted over and below the mantle trough. It should be emphasized that this seismic "gap" extends from the surface into the upper mantle. The above-listed geological, age and seismic data suggests that the Kirovograd ore district developed under three different geodynamic environments (Fig. 5). The first was marked by the formation of the Novoukrainsk-Kirovograd granitoid massif as a constituent of the intrusive-ultrametamorphic base- ment, the second resulted in the tectonic activiza- tion of the basement, the third was dominated by the emplacement of the Korsun’-Nowomirgorod ra- pakivi-anorthosite massif. Taking into consideration a unique combination of tectonic structures, intru- sive rocks, deposits and geodynamic environments, we regard the Kirovograd ore district as a Paleopro- terozoic center of intense conjugated mantle-crust magmatism and endogenous ore formation. The work is performed according to a research agreement between IGPH and IGEM and suppor- ted by the program P-22 Rassian Academy of Sci- ences. Fig. 4.
