ASITA characterizes the LOMU–ELMU protomantle melt anomalies of the lower mantle high velocity skeleton of Asia during the early mantle geodynamic epoch. SOPITA and AFITA are marked by the HIMU plume component, which was generated in the low-velocity lower mantle of the South Pacific and Africa during the middle mantle geodynamic epoch, about 2 Ga. NAITA denotes processes of generation of the North American high-velocity lower-mantle anomaly in the late geodynamic epoch. Of regional importance are sub-lithospheric sources that are characterized by a common geochemical structure of volcanic rocks of large volcanic regions, formed due to the evolution of homogeneous proto-mantle deep reservoirs. An example is sources of the Wulanhada-Hannuoba and Abaga-Dariganga volcanic regions, marking the spatial transition from the LOMU proto-mantle reservoir of the former to the ELMU one of the latter. Local sources of volcanoes are displayed in limited volumes of melts from the heterogeneous lithosphere. An example is sources of the Wudalianchi volcanic field, on which, at first, in the time interval of 2.5–0.8 Ma, the material of the Laoshantou and Gelaqiu sources with a common age of 1.88 Ga occurred, and then, during the spatial-temporal evolution of volcanism in the last 0.6 Ma, the material from these sources was mixed with a younger lithospheric material.","PeriodicalId":44327,"journal":{"name":"Italian Journal of Engineering Geology and Environment","volume":"20 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85281523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Present-day Moho discontinuities only partially coincide with petrological estimates of a change from felsic-basic rocks (that belong to the continental crust) by predominantly ultramafic rocks (that represent the continental mantle lithosphere) and often lie much deeper than the PZСMT. Depths of such zones change over time. For a garnet-free assemblage of deep-seated nodules ejected by basaltic melts about 13 Ma ago from the root of a granulite terrane exposed in the eastern part of the Tunka Valley, two PT trends were obtained, one of which corresponds to a high (up to 120 mW/m2) rift conductive geotherm, another one crosses low conductive geotherms (drops below 60 mW/m2 one). The PZСMT shows here a temperature approximately 200°C lower than the PZСMT of granulite terranes in Eastern Australia, China, and Svalbard. Deep-seated nodules characterize the development of hot transtension under the rift valley in the cold root part of the East Tunka block with the accumulation and release of elastic stresses accompanied by significant synkinematic (metasomatic and magmatic) processes in the time interval 18–12 Ma ago. The transtension was followed by a crustal transpression with inversional uplift of an area and a probable relative increase in the depth of the Moho discontinuity, determined from the both P- and S-wave velocities for the modern crust and lithospheric part of the mantle.","PeriodicalId":44327,"journal":{"name":"Italian Journal of Engineering Geology and Environment","volume":"4 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85314869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
