The discipline of structural geology is taking an advantage compiling observations from multiple field sites to comprehend the bigger picture and constrain region's geological evolution. In this study we demonstrate how integration a range geospatial digital data sets that relate Paleogene fault thrust belt exposed in high Arctic Archipelago Svalbard, used teaching bachelor-level courses at Uni...
the zagros fold-and-thrust belt is tectonically active and often has active faults with insensible and slow motions. determining the rate of movement and displacement in these faults requires very precise measurements. one of the measurement methods of fault movements is using geodetic and micro-geodetic studies. this research is focused on one of the active faults in the north of shiraz city, ...
Despite their markedly different structural setting, the northern and southern outer Albanides share a common tectonic evolution from detachment-dominated to ramp-dominated, basement-involved thrusting. The former process (mainly Oligocene Miocene) is essentially related with occurrence of thick décollement level represented by Triassic evaporites, while latter involves basement ramps splaying ...
Prospectivity modelling has been completed over the Lachlan Fold Belt, New South Wales, Australia, using the GIS based weights of evidence modelling technique to target porphyry Cu-Au, associated skarn Cu-Au, orogenic Au and VMS Au mineralisation. The Lachlan Fold Belt is a 700 km wide belt of Paleozoic accretionary terrains, stretching from Queensland to Tasmania. Porphyry and skarn mineralisa...
We examine rockfall susceptibility of folded strata in the Sevier fold-thrust belt exposed in American Fork Canyon in north-central Utah. Large-scale geologic mapping, talus production data, rock-mass-quality measurements, and historical rockfall data indicate that rockfall susceptibility is correlated with limb dip and curvature of the folded, cliff-forming Mississippian limestones. On fold li...
The Kuh-e- Sefid and Banari phosphate horizons in Zagros Simply fold belt occurred in Pabdeh Formation. At this regard several samples collected from two phosphate horizons, for ICP-MS analyses. The result of ICP-MS analyses show that major oxides in two horizons are CaO> SiO2> Al2O3> Fe2O3> P2O5 respectively that the values of P2O5 in the Banari and Kuh-e- Sefid horizons is low and about 1.95 ...
Fault rocks from the classic Rocky Mountain foreland fold-and-thrust belt in southwestern Canada were dated by Ar analysis of clay grain-size fractions. Using X-ray diffraction quantification of the detrital and authigenic component of each fraction, these determinations give ages for individual faults in the area (illite age analysis). The resulting ages cluster around 72 and 52 Ma (here calle...
An ethno botanical survey was undertaken to collect information from Yanadi tribe of Cheruvukattasangham, Kavali, Nellore district, Andhra Pradesh, India. Kavali is a part of Eastern Ghats Mobile Belt which is a Precambrian fold belt extending over 600 km along the east coast of India from the North of Cuttack in Orissa to Nellore in Andhra Pradesh. Yanadi tribe is most prevalent in this region...
