DEPTH OF CURIE TEMPERATURE COMPUTED FROM AEROMAGNETIC ANOMALIES IN SOUTHEASTERN MINAS GERAIS. BRAZIL
In this paper, ferroelectric thin films, described by an ising model in a transverse field, have been studied under the mean-field approximation. We discuss a thin film composed of N-layer film of simple cubic symmetry with nearest-neighbor exchange in which the exchange strength and transverse field are assumed to be different from the bulk values in Ns surface layers, and we derive and illust...
This study aims to determine Curie point depth (CPD), Heat flow and the boundaries of geological structures Cyprus Island using EMAG2 magnetic data. CPD values were calculated by applying spectral analysis technique anomaly map divided into 60 blocks (60x60 km2). Then, different thermal conductivity (K=1, 1.5 2.5 Wm–1 K–1) heat values. ranged from 12.4 km 28.18 km, between 20 50 mW/m2 for K=1. ...
This research deals with assessment of geothermal potential in parts of middle Benue Trough, north-east of Nigeria. The study area lies within the Longitude 9°E – 10°E and Latitude 8°N – 9.50°N with an estimated total area of 18,150 km2. Regional/Residual separation was performed on the total magnetic intensity using polynomial fitting. The residual map was divided into 14 overlappin...
today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
Abstract The estimation of the Curie point depth (CPD) and heat flow (HF) from magnetic data is useful for geothermal tectonic studies. However, methodology estimating these values still controversial as numerous studies have used different types transformed data. Most utilize total intensity (TMI) or reduced to pole (RTP) data, since shallow bodies may affect final CPD values, low-pass (LP) wa...
