Mention will be made of the different techniques used at the time, such as seismology, petrology, geology, among others that have allowed deepening the knowledge of the basement of the Tulum valley, and how first-order structures play an essential role in geometry. and circulation of meteoric water at depths high enough to reemerge as thermal manifestations.	PhD. Pérez Luján, Sofía -Researcher- ([email protected])	https://www.youtube.com/watch?v=Y2GfILjB6KY&t=8s
25/08/21	Ciclo de exposición de tesis de egresados de la UNSJ DETERMINACIÓN DE UNIDADES AMBIENTALES PARA EL MODELO DE ORDENAMIENTO TERRITORIAL CONTROLADO AL NORTE DEL VALLE DE TULUM (PROVINCIA DE SAN JUAN).	This talk addresses the work carried out in the department of Angaco, a populated area north of the Tulum Valley, province of San Juan, Argentina. This work consists of a geophysical study in two west-east transects, from the valley to the foothills of the Pie de Palo mountain range, where it was possible to observe the geophysical responses to determine tectonic structures and establish their relationship with the units geomorphological and superficial Quaternary deposits. For this, tools and principles of geophysical methods were used: gravimetry and magnetism.	Lic. Grígolo, Agostina ([email protected])	https://www.youtube.com/watch?v=ofqUJ3OFz5Y&t=18s

Lovecchio, Juan Pablo -Offshore Exploration Geologist at YPF and President of AAGGP- ([email protected])	https://www.youtube.com/watch?v=xPYI8W13ykg
08/09/21	Monitoreo volcánico: sismicidad y otras técnicas geofísicas aplicadas a volcanes	Seismicity is perhaps the quintessential volcanic monitoring technique for short-term forecasting, as well as for estimating the base activity of the volcanic system. Through the different types of volcanic seismicity it is possible to understand the state of activity of the volcano; and through seismology it is possible to show magma advances in non-visible structures, as well as to estimate the location of possible magma reservoirs. Volcano deformation is also used as a monitoring measure associated with periods of volcano inflation/deflation before or after an eruption. The need to observe some volcanoes in remote areas, such as the Aleutian (USA) and Kuril (Russia) arcs, has led to the use of remote sensing techniques such as InSAR for these same purposes. In addition, a variety of electrical and electromagnetic methods have been used for subsurface studies, both for estimates of geothermal potential and for monitoring the structures themselves. On the surface, the monitoring of degassing, thermal radiance, and infrasound signals allow the study of other characteristics of volcanic activity both on the ground and at a distance. Together with seismicity and other geophysical and remote sensing techniques, it is possible to build a monitoring system that considers the different variables that the volcano shows, its different states, and thus improve early warning of eruptions and associated dangers.	PhD. Mora-Stock, Cindy ([email protected])	-
15/09/21	Estudio de litofacies y organofacies en una secuencia del cretáceo de la cuenca oriental de Venezuela	The Upper Cretaceous San Antonio Formation is characterized by a sequence of limestones, marly limestones, marls, shales, and sandstones. This talk will address a detailed study in the type section of the San Antonio Formation (300 m) to determine the variation of geochemical parameters as indicators of lithofacies and organic facies derived from the contribution of organic matter and types of sediments in the basin. The potential for hydrocarbon generation in the section is estimated based on the quantity, type and maturity of the kerogen. This sequence was deposited under suboxic to anoxic conditions, characterized by kerogen type II. Limestones, marly limestones, marls and shales have been considered as a secondary source rock in the Eastern Basin of Venezuela. This section presents differences in terms of the potential for hydrocarbon generation, related to the lithofacies and the organic facies. Additionally, sandstones act as accumulation zones for hydrocarbons generated and expelled from limestone, marly limestone, marl and shale.	PhD.
