The main peak corresponds to the beginning of the Ordovician period (circa 480 Ma), and the secondary peaks correspond to the beginning of the Late Ordovician, the middle Cambrian, and the early Cambrian. The clastic material was derived from the East Ural megazone exclusively.","PeriodicalId":253271,"journal":{"name":"Moscow University Bulletin. Series 4.

The most striking and well-preserved example of such interaction in the geological past is the “collision” of the Southeast Indian spreading ridge and the Kerguelen plateau, which occurred about 43 Maago. The consequence of this event was the division of a single Kerguelen plateau into two parts: in fact, the Kerguelen plateau and the Broken ridge. The conditions for the formation of these morphostructures were studied experimentally. The paper presents the results of modeling the interaction of a spreading ridge with a large igneous province. The experimental results correlate well with geological and geophysical data and with the proposed model for the development of this region.","PeriodicalId":253271,"journal":{"name":"Moscow University Bulletin.

Model parameters included temperature (130–140 °C), calculated on the basis of geothermometers, and the residence time of waters in the rock massif (68 800–254 000 years), estimated by means of 14C and 4He dating. The modeling results show that exactly the filtration parameters of the granite massif are the main factor controlling the dynamics of fluid movement and, consequently, the relative age of thermal waters. It is also found that the filtration characteristics of the fault zone have a significant influence on the temperature of thermal water discharge.","PeriodicalId":253271,"journal":{"name":"Moscow University Bulletin.

Analysis of 130 Fourier-IR absorption spectra of plagioclases with selective verification of their chemical composition by X-ray spectral microanalysis indicates a regular change in the isomorphic series from albite (1150, 1096 cm–1) to anorthite (1142, 1275 cm–1), depending on the degree of differentiation of rocks in the intrusion. According to Fourier-IR spectroscopy, albite is confined to olivine-containing and olivine gabbro-dolerites. Anorthite is evenly distributed in gabbro-dolerites, but predominates in leucocratic gabbro. Among the impurity elements in the structure of the mineral, Fe3+ is noted at peaks of 1580–1644 cm–1 in picrite gabbro-dolerites, where ore interspersed mineralization of chalcopyrite, pyrrhotite, and pentlandite is directly developed. In addition to iron impurities, aluminum, potassium, barium, and strontium are also characteristic impurities in plagioclases. The totality of the data used in the section of the intrusion increases the indicative value of plagioclases and can be recommended as an additional mineral criterion of ore content.","PeriodicalId":253271,"journal":{"name":"Moscow University Bulletin.

The modeling results showed that fragments of the oceanic crust introduced into the metamorphosed complexes of the continental crust during the collision can have a dual origin — from the primary oceanic crust, and from the newly formed crust of the back-arc basin. A detailed chemical composition analysis of the Stanovsky ophiolites indicates their formation in the suprasubduction setting of the back-arc basin, which justifies the possibility of the second scenario.","PeriodicalId":253271,"journal":{"name":"Moscow University Bulletin.

In the western part of the studied water area, the de Geer moraines were first identifi ed in a complex of glacial deposits, which were formed during the retreat of the glacier in the late Pleistocene in an easterly direction towards the modern deep-water part of the White Sea. In the deep-water part of the water area, according to the data of the MBE and CSP, sediments were studied, the genesis of which is due to the intensive manifestation of gravitational processes at the end of the Late Pleistocene — Holocene.
