“…This subsidence pattern has expanded into new areas in the south-east, north-west, and parts of the south of the Hashtgerd city. The results of 27,29 indicate a maximum subsidence of 14 and 16 cm/year for the years 2003 to 2008 and 2015 to 2020, respectively, indicating an increase in the rate of subsidence.…”

Due to its proximity to Tehran, the Hashtgerd catchment in Iran is an important region that has experienced alarming subsidence rates in recent years. This study estimated the ground surface deformation in the Hashtgerd plain between 2015 and 2020 using Sentinel-1 SAR data and InSAR technique. The average LOS displacement of the ascending and descending tracks was − 23 cm/year and − 22 cm/year, respectively. The central area of the plain experienced the greatest vertical subsidence, with a more than − 100 cm cumulative displacement. The Karaj-Qazvin railway and highway that pass through this area have been damaged by subsidence, according to an analysis of profiles drawn along the transportation lines. The southern sections of Hashtgerd city have experienced a total displacement of − 30 cm/year over the course of about 6 years. The relationship between changes in groundwater level and subsidence rate in this region was examined using piezometer and precipitation data. Geoelectric sections and piezometric well logs were also utilized to investigate the geological characteristics of the Hashtgerd aquifer. According to the findings, the leading causes of subsidence were uncontrolled groundwater abstraction. This research highlights the need to comprehend the spatial distribution of confined aquifers and their effect on subsidence, which can aid in the development of a suitable management strategy to restore these aquifers.

“…Near the city of Hashtgerd, a tectonic survey identified a crushed zone caused by collisions between active tectonic plates. The results clearly demonstrate intense activities at the center of the plain, with a significant correlation between the crushed zone and the hypocenter of large earthquakes 27 .…”

“…The Relationship between surface structures (e.g., Khavari et al, 2009;Arian et al, 2012;Arian and Aran, 2014;Ehsani and Arian, 2015;Aram and Arian, 2016) and basement faulting (e.g., Nabilou et al, 2018;Mansouri et al, 2018) show that Iran is affected by active tectonics. In terms of lithofacies, especially the role of tectonics in the Iran sedimentary basin, Arian (2015), Razaghian et al (2018) and Taesiri et al (2020) divided all rocks into several large tectonic-stratigraphic units. In most areas of the Central Iran, Paleozoic-Cenozoic sediments are concordance due to stratigraphic gaps, indicating tectonic movements (Rahgoshay et al, 2018(Rahgoshay et al, , 2019.…”

“…The Relationship between sedimentary basins (e.g., Khavari et al, 2009;, 2012; Arian and Aram, 2014;Ehsani and Arian, 2015;Aram and Arian, 2016) and basement faulting (e.g., Arian, 2012;Nouri et al, 2013a,b;Mansouri et al, 2017;Nouri and Arian, 2017;Mansouri et al, 2018;Nabilou et al, 2018) indicates the role of faults in the control of sedimentary basins in Iran. In terms of lithofacies, especially the role of tectonics in the Iran sedimentary basin, Arian (2015), Razaghian et al (2018) and Taesiri et al (2020) divided all rocks into several large tectonic-stratigraphic units. In the study region, structures have a northwest-southeast trend, and the role of the paleogeographic faults in basin segregation over time is significant.…”

The Sarvak and Ilam Formations in the Zagros sedimentary basin are known as reservoir ROCKs. Over 50 hydrocarbon fields are in the Zagros basin at the Sarvak and Ilam hydrocarbon Formations, and the Fars region is about 5%. This research identifies areas with hydrocarbon potential of the Formation of Sarvak and Ilam at Fars area parameters such as Formations outcrop, main faults, isopach maps, and volume of upper Formations sediments extracted from geology map of the area. With fuzzification of the layers and overlapping them with each other, the areas with high hydrocarbon potential were identified in the Ilam and Sarvak Formations. Regarding exploration potential in the Sarvak and Ilam Formations, the Fars region was identified as an area with poor hydrocarbon potential. Somehow 75.25% of the Fars area has inferior hydrocarbon potential, 18.5% has standard hydrocarbon potential, and only 6.25% has high hydrocarbons potential for exploration at the Sarvak and Ilam Formations. While considering to fault effect and their outcrops, the percent of areas with high hydrocarbon potential decreased to 3.6%. Also, Fuzzy logic as a multi-value logic from masters knowledge and designed inference network could identify all fields with hydrocarbons potential in the Sarvak and Ilam Formations in the Fars area and recognize those areas as a high hydrocarbons potential.
