Mandsaur district forms the Northern projection of Madhya Pradesh. It lies between the parallels of 23 45’50” to 25 02’55” North latitude and between the meridians of 74 42’30”to 75 50’20” East longitude. The district extends for about 142 km. from North to South and 124 km. from east to West. The district lies on the Malwa plateau. The top cover consists of black cotton soil which is ideal for...
As the oldest exposed basement and the typical sedimentary cover of the Yangtze craton, the Huangling massif is a suitable place to decipher the tectonics of South China block. Structural analysis shows that the Huangling massif has an elliptic domal shape with N–S striking long axis, an asymmetric antiform with a steep western flank and a gentle eastern flank. There, three litho-tectonic units...
In this paper, we propose an advanced methodology to perform three-dimensional (3D) Finite Element (FE) modeling to investigate the kinematical evolution of a slow landslide phenomenon. Our approach benefits from the effective integration of the available geological, geotechnical and satellite datasets to perform an accurate simulation of the landslide process. More specifically, we fully explo...
abstract aim of this research is landslide hazard zoning in syahdare watershed using logistic regression. therefore, outset landslide points recognized using air photography and extensive field studies. then distribution of landslide map was makes. then each effective element on landslide occurred for example slope, aspect, elevation, litho logy, land use, distance of road, distance of drainage...
Located along the Tigris River in Kurdistan Region of Iraq, Mosul Dam reservoir is second biggest dam Near East and represents an important water storage for local human activities. The was built between 1981 1988 north village Eski Mosul, submerging course ca 100 km. analysis historical images derived from declassified Corona satellite imagery acquired December 1967 August 1968 reveals pristin...
Despite the increasing technological level of reflection seismic method, imaging fold and thrust belts remains a demanding task, usually leaves some questions regarding dips, shape subthrust structures or most correct approach to velocity model building. There is no straightforward method that can provide structural representation near-surface geological boundaries their velocities. The in-terp...
Geochemical data are frequently collected from mineral exploration drill-hole samples to more accurately define and characterise the geological units intersected by drill hole. However, large multi-element sets slow challenging interpret without using some form of automated analysis, such as mathematical, statistical or machine learning techniques. Automated analysis techniques also have advant...
Geological mapping undoubtedly plays an important role in several studies and remote sensing data are of great significance geological mapping, particularly poorly mapped areas situated inaccessible regions. In the present study, Principal Component Analysis (PCA), Band Rationing (BR) Minimum Noise Fraction (MNF) algorithms applied to map lithological units extract lineaments Amezri-Amassine ar...
In this study, we present new data from microthermometry of fluid inclusions entrapped in hydrothermal veins along the Cocos Ridge from the IODP Expedition 344 Site U1414. The results of our study concern a primary task of IODP Expedition 344 to evaluate fluid/rock interaction linked with the tectonic evolution of the incoming Cocos Plate from the Early Miocene up to recent times. Aqueous, low ...
