It was shown that in the roots of SA-treated plants, the activity of lipid peroxidation is higher compared to untreated ones, especially in the case of nematode invasion. A significant increase in the activity of lipid peroxidation in SA-treated invasive plants compared with untreated was noted during the transition of larvae to the sedimentary stage and the beginning of the formation of feeding places - giant cells (3-5 days after invasion). This, apparently, contributes to the inhibition of the development of the parasite and the reduction of plant infection, and also indicates the involvement of oxidative processes in the mechanism of the induced resistance of plants to root-knot nematodes. In the SA-treated plants, the qualitative and quantitative composition of photosynthetic pigments, disturbed by invasion, was restored and corresponded to the control level.","PeriodicalId":24047,"journal":{"name":"Доклады Академии наук","volume":"68 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90599142","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}

The interaction of phlogopite with carbonate melt resulted in the formation of a polymineral association of relic and newly formed phases of the phlogopite-carbonate-clinopyroxene-spinel-garnet composition coexisting with carbonate melt. By increasing the temperature from 1200 to 1300 C in the carbonate melt increases the solubility of phlogopite and the concentrations of its components - Si, Al, Mg, K. The phase composition of the quenching phases of the carbonate melt varies from substantially carbonate with isolated microcrystals of apatite and phlogopite at 1200 C to phlogopite-carbonate with a variety of texture ratios at 1300 C, reflecting the spontaneous crystallization of the carbonate melt during quenching. In the studied P-T, close to the mantle adiabate, phlogopite remains stable in the presence of silicate-carbonate melt.","PeriodicalId":24047,"journal":{"name":"Доклады Академии наук","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90557034","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}

Secondary ions mass-spectrometry (SIMS) was used for U-Th-Pb-zircon age definition, on SRHIMP-II device and mass spectrometry with inductively associated plasm with LA-ICPMS ablation on ThermoQuest Finnigan MAT Neptune device. Televi Formation basalt conglomerates, Luchlompo Formation red colored gravelites and middle part Matert Formation high siliceous turbidites were tested. On U-Pb diagram with Concordia part of analytical points for zircon from conglomerates are approximated by Discordia with the top intersection 2792 7 Ma. All gravelite zircon grains are located on Concordia. The main part of their age values is within interval 2700-2820, the lesser - 2840-3000 Ma (with the maximums 2718, 2779, 2854, 2972). The single grains have the age from 3037 4 up to 3698 8 Ma. Concordant value 207Pb/206Pb age 2640 16 Ma is fixed for turbidite zircon. The sources of zircon for conglomerates and gravelites were the rocks of Northern zone Pechenga structure basement: gneisses of Kirkenes, Varanger and Svanvik Complexes (2715, 2803 and 2825 Ma) and high aluminous gneisses (2798-2830 Ma), for turbidites - Southern slope granitoides. The dominating role of zircon group with 2. 7 billion years proves a global growth of continental crust in this period. Ancient values of zircon age (3.0-3.7 billion years) of red colored gravelites are connected with the deeper erosion of the basement and outcrop of Eoarchaean and Mezoarchaean age rocks on erosive surface in Northern zone within the period of the first global Oxygen revolution (2.4-2.3 billion years).","PeriodicalId":24047,"journal":{"name":"Доклады Академии наук","volume":"70 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80655486","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}
