Bouguer gravity anomalies (BGA) play an important role in exploration of mineral resources. Allowing the delineation large geological structures, BGA participate into discovery deposits. However, Kiri uplift region where several oil seeps have been recognized faces sparse coverage data due to difficult conditions acquisition on field. This situation increases non-uniqueness and nonlinearity pro...
Different methods of lithology predictions from geophysical data have been developed in the last 15 years. The geophysical logs used for predicting lithology are the conventional logs: sonic, neutron-neutron, gamma (total natural-gamma) and density (backscattered gamma-gamma). The prompt gamma neutron activation analysis (PGNAA) is another established geophysical logging technique for in situ e...
saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
The fine characterization of channel sand body is a complex system engineering. longitudinal superposition relationship complex, the sandstone thickness thin, and lateral changes lithology physical properties are obvious. It necessary to carry out research on integration processing interpretation seismic geology. key technologies high-resolution pre stack post inversion medium shallow bodies wi...
desertification is specific phenomenon of arid, semi-arid, dry sub humid regions. this phenomenon has a high rate in developing countries such as iran. the main objective of this research was calibration of imdpa model in abuzeidabad (kashan) region with emphasis on land criteria. imdpa model, introduced by iranian researchers to assess desertification intensity in iran. before application, the...
The Schlumberger and Wenner Electrical Resistivity Survey techniques have been used in comparison for the determination of groundwater potential District Rawalakot, Azad Jammu Kashmir. terameter SAS4000 with accessories was data acquisition. were processed by employing IPI2WIN software to determine depth, thickness true resistivity subsurface layers. present study indicated depth coverage confi...
Far-ultraviolet (FUV) spectra in the 190-300 nm region were measured for spring water in Awaji-Akashi area, Tamba area and Rokko-Arima area in Hyogo Prefecture, Japan, these areas have quite different geology features. The spectra of the spring water in the Awaji-Akashi area can be divided into two groups: the spring water samples containing large amounts of NO(3)(-) and/or Cl(-), and those con...
Disposal is a critical phase in the management of municipal solid waste, due to unavailability suitable facilities treat and dispose large amount waste generated daily metropolitan cities. Improper disposal locally, cause environmental impacts such as contamination soil, water pollution, increase methane emissions. In this study, an attempt has been made use GIS remote sensing identify high pot...
Abstract This study was aimed at delineating groundwater potential zones (GWPZ) using geo-spatial techniques for Ranchi district, Jharkhand (India). Data including Cartosat-1 digital elevation model (DEM), Landsat 8 satellite images, lithology, geology, soil, and water yield data were utilised in this study. The relative importance of multiple parameters slope, rainfall, drainage density, land ...
Abstract Landslide forensics assessment was conducted in Cimanggung, Sumedang with the aim of identifying causes and processes landslides to guide critical step future disaster prevention. The methodology includes investigations on geology, lithology, hydrology, land cover, land-use changes, rainfall triggering landslide. Unmanned Aerial Vehicles were used investigate detailed spatial geomorpho...
