ABOUT THE VERTICAL COMPONENT OF THE ELECTRIC MAGNETO-TELLURIC FIELD STRENGTH IN THE RANGE SHORT-PERIOD OSCILLATIONS
Authors: Вишнев В.С. , Астафьев П.Ф. 
Published: July 2024

Рассмотрены методические приемы полевого эксперимента по изучению вклада галь- ванического возбуждения земных недр геомагнитными вариациями в суммарное естественное элек- тромагнитное поле диапазона короткопериодических колебаний. Произведено сравнение скважинных распределений отношений вертикальных составляющих электрической напряженности естественного и искусственно созданного полей к их горизонтальным составляющим. Сделано предположение о том, что доля вклада этого типа возбуждения Земли (по сравнению с индукционным возбуждением) на тер- риториях, относящихся к средним широтам, много меньше требуемой точности электроразведочных измерений, но, по мере продвижения на север, будет расти. Рассматриваемые методические приемы могут быть использованы при проектировании геофизических работ методами магнитотеллурического профилирования или зондирования в северных районах страны.
Methodological techniques of a fi eld experiment to study the contribution of galvanic excitation of the Earth’s interior by geomagnetic variations to the total natural electromagnetic fi eld of the short-period oscillations range are considered. The comparison of borehole distributions of the ratios of the vertical components of the electric intensity of the natural and artifi cially created fi elds to their horizontal components is made. It is assumed that the share of the contribution of this type of excitation (compared with induction excitation) in the territories belonging to the middle and low latitudes is much less than the required accuracy of electrical survey measurements, but, as we move north, it will grow. The considered methods can be used in the design of geophysical works by the methods of magnetotelluric profi ling or sounding in the northern regions of the country.

Для обеспечения как краткосрочного, так и долгосрочного прогноза землетрясений необходимо иметь адекватную модель геологической среды. В нашем случае предлагается многофазная контрастная модель, представляющая собой неоднородную пористую проницаемую влагонасыщенную среду в поле переменных тектонических напряжений. Считаем, что в зоне предполагаемого тектонического события в период его подготовки развивается неоднородное дилатирующее включение, которое представляет собой набор дилатирующих мезовключений, связанных между собой проницаемыми каналами. В зависимости от динамических условий на границе включений могут существовать недренажные условия. В этом случае в зоне включения возникает пониженное давление жидкости и на границе включения регистрируется дроссельный эффект (эффект Джоуля – Томсона). Тогда в зоне контакта наблюдается участок пониженной температуры, который может быть интерпретирован как предвестник тектонического события.
To provide both short-term and long-term earthquake prediction, it is necessary to have an adequate model of the geological environment. In our case, a multiphase contrast model is proposed, which is a heterogeneous porous permeable moisture-saturated medium in a fi eld of variable tectonic stresses. We believe that in the zone of the proposed tectonic event, during the period of its preparation, a heterogeneous dilatant inclusion develops, which is a set of dilatant meso-inclusions interconnected by permeable channels. Depending on the dynamic conditions, undrained conditions may exist at the boundary of the inclusions. In this case, a reduced fl uid pressure occurs in the switching zone, and a throttle effect (Joule-Thomson effect) is recorded at the switching boundary. Then, in the contact zone, there is an area of low temperature, which can be interpreted as a precursor of a tectonic event.

Published: July 2024

Рассмотрены результаты обработки синхронных наблюдений короткопериодических вариаций магнитотеллурического поля, полученных на ряде широтных пересечений Урала. Показано, что первичная часть этого поля на территории Среднего и Южного Урала практически однородна и магнитотеллурические методы геофизической разведки могут дать там вполне приемлемые геологические сведения.
The results of processing synchronous observations of short-period variations of the magnetotelluric fi eld obtained at a number of latitudinal intersections of the Urals are considered. It is shown that the primary part of this fi eld on the territory of the Middle and Southern Urals is almost homogeneous and magnetotelluric methods of geophysical exploration can give quite acceptable geological information there.

GEOTHERMAL MODELS OF LAYER-HETEROGENEOUS MEDIA. DIVISION OF THE FLOW INTO THE CORUS AND MANLE COMPONENTS
Authors: Ладовский И.В. , Бызов Д.Д. 
Published: July 2024

Реализован метод решения задач сопряжения для уравнения Пуассона, позволяющий интерпретировать потенциальные поля (гравитационное и стационарное тепловое) на основе унифицированных сеточных алгоритмов. Выполнено послойное разделение теплового потока на аддитивные составляющие от источников земной коры и верхней мантий. Разработан численный алгоритм пересчета мантийной составляющей теплового потока от уровня земной поверхности к границе «кора-мантия» через неоднородную по теплопроводности слоистую среду. Мантийный тепловой поток, равно как и значения мантийных температур, служат индикатором скоростных неоднородностей по отражающим горизонтам верхней мантии. Дано сравнение послойных тепловых и гравитационных аномалий и установлена степень их стохастической близости. Использование данных о тепловом потоке позволяет значительно повысить геологическую информативность гравитационного и сейсмического моделирования. В измеренные значения градиента температуры и теплового потока для северных территорий введены палеоклиматические поправки. В осевой части Уральской геосинклинали удалось исключить отрицательную депрессию мантийной составляющей теплового потока, полученную по результатам геотермического моделирования; учет плейстоцен-голоценового потепления предшествующего межледникового палеоклиматического цикла приводит к положительным значениям теплового потока, пе- ресчитанного на границу «кора-мантия».
A method for solving conjugation problems for the Poisson equation is implemented, which makes it possible to interpret potential fi elds (gravitational and stationary thermal) based on unifi ed grid algorithms. The layer-by-layer separation of the heat fl ux into additive components from the sources of the earth’s crust and upper mantle has been carried out. A numerical algorithm has been developed for recalculating the mantle component of the heat fl ow from the level of the earth’s surface to the “crust-mantle” boundary through a layered medium inhomogeneous in thermal conductivity. The mantle heat fl ow, as well as the values of mantle temperatures, serve as an indicator of velocity inhomogeneities along the refl ecting horizons of the upper mantle. A comparison of layer-by-layer thermal and gravitational anomalies is given and the degree of their stochastic similarity is established. The use of heat fl ow data can signifi cantly increase the geological information content of gravity and seismic modeling. Paleoclimatic corrections were introduced into the measured values of the temperature gradient and heat fl ux for the northern territories. In the axial part of the Ural geosyncline, it was possible to exclude the negative depression of the mantle component of the heat fl ow, obtained from the results of geothermal modeling; taking into account the Pleistocene-Holocene warming of the preceding interglacial paleoclimatic cycle leads to positive values of the heat fl ow recalculated to the “crust-mantle” boundary.

Published: July 2024

В работе приведено описание технологии трехмерной интерпретации магнитных аномалий с учетом рельефа земной поверхности. Ключевые элементы технологии (выделения аномалий и вычисления поверхности источников) применены при исследовании намагниченных массивов Уральского орогена на территории 100х100 км, включающей Центрально-Уральскую и Тагильскую мегазоны. Высота горных хребтов на этом участке достигает 1000-1500 метров. Приведены результаты моделирования кровли источников магнитных аномалий, как учетом горного рельефа земной поверхности, так и для горизонтальной плоскости. Наиболее ярко отличия проявляются для моделей ультрабазит-базитовых комплексов массивов Платиноносного пояса Урала, выведенных на земную поверхность и образующих высокие горы.
The paper describes the technology for three-dimensional interpretation of magnetic anomalies taking into account the topography of the earth’s surface. Key elements of the technology (separation of anomalies and calculation of the source surface) were used in the study of magnetized massifs of the Ural orogen over an area of 100x100 km, including the Central Ural and Tagil megazones. The height of the mountain ranges in this area reaches 1000-1500 meters. The results of modeling the roof of sources of magnetic anomalies are presented, both taking into account the mountainous topography of the earth’s surface and for the horizontal plane. The differences are most pronounced for the models of ultramafi c-maphic complexes of the massifs of the Platinum Belt of the Urals, exposed on the earth’s surface and forming high mountains.

Published: July 2024

Acknowledged as a far-reaching pedagogical method, Project-Based Learning is nationally imperative in Indonesian education despite the disinclination of its execution. This paper scrutinizes the phonetics and phonology-based English pronunciation dimensions and scaffolding traits as the bases to devise the scaffolding assignments for PBL execution, explores the process of PBL with scaffolding assignment adoption, and examines whether the exertion of the PBL enhances the academic achievement of English pronunciation and autodidacticism as Self-Directed Learning skills. The study exploits design-based research through repetitive actions of analysing, designing, developing, implementing, and evaluating. The result exhibit that the scaffolding assignments are designed by decomposing the phonetics and phonology pronunciation-related conceptions into smaller tasks of English pronunciation learnings and trainings based on instructional scaffolding fundamentals. The scaffolding assignments infused PBL is applied through orientation, action, reflection, and presentation stages which cover the learning activities of launching the project as the entry event marked with the driving question disclosure; building knowledge, understanding, and skills to answer the driving question; developing the project products and answers to the driving question; and presenting the products and answers to the driving question. The exertion of the PBL with scaffolding assignments is proven influential in promoting the students’ English pronunciation and Self-Directed Learning skills.
