Some Results of Studying Changes in Gas and Isotopic Composition of Subterranean Waters In Preparatory Phase Of Seismic Activation Of Nazarbek Earthquake

Abstract

This Paper Considers The Results Of Comprehensive Monitoring Observations Of Changes In The Gas And Isotopic Composition Of The Subterranean Waters Of Cretaceous Deposits Of Cenomanian Strata In Deep Wells Of Seismically Active Areas In Central Asia, Where The Risk Of Earthquake Is Pretty High. The Object Of Research Are The Subterranean Waters Of The Cretaceous Deposits Of The Cenomanian Strata Of The Artesian Basin Near Tashkent. In This Context, The Studyâs Relevance Is Determined By The Peculiarity Of Their Response To Changes In The Rock Stresses Related To The Pre-Earthquake Phase. The Studies Pay Special Attention To Analyzing Phenomena Observed In The Gas-Water-Rock System Because The Correlation Between The Pre-Earthquake Phase And The Rate, At Which Chemical Components Go From Water To Porous Solution, Ultimately Determines The Existence Of Geochemical Anomalies. The Leading Approach To This Investigation Is To Study The Kind Of Changes In The Variations In The Isotopic
