Curie point depth based on spectrum analysis of the magnetic anomaly data in East and Southeast Asia

New techniques for estimation of source parameters: Applications to airborne gravity and pseudo-gravity gradient tensors

“…In recent years, this approach is widely adopted for estimating Curie-isotherm depth of the crustal rocks (e.g. Hong et al, 1982;Okubo et al, 1994;Tanaka et al, 1999;Aydin et al, 2005;Ross et al, 2006;Aydin and Oksum, 2010). Abdeslem (1995) introduced a method for interpretation of gravity anomalies using prism model.…”

Estimation of Curie point depths and heat flow from Ardebil province, Iran, using aeromagnetic data

“…Connard et al (1983) divided a magnetic data of the Cascade Range, central Oregon, into overlapping blocks (77 × 77 km) and calculated the radially average power spectrum for each block. Tanaka et al (1999) divided the East and Southeast Asia into sub-region data (approximately 200 × 200 km) and estimated the power density spectra for each region. Blakely (1988) divided the area of Nevada into blocks (120 × 120 km) in terms of magnetic or aeromagnetic data and mapped the CDP of Nevada state.…”

“…The results of his investigations revealed that the CPD varies considerably beneath Greece, reaching 20 km towards western Greece and about 10 km beneath the Aegean. In East and Southeast Asia, CPD was determined based on the spectral analysis of magnetic anomaly data by Tanaka et al (1999). In this study, they used many heat flow data from the boreholes.…”

Tectonic Escape Mechanism in the Crustal Evolution of Eastern Anatolian Region (Turkey)

“…Elitok and Dolmaz (2008) implied that the CPD is in close relationship with the crustal thickness, crust-hot asthenospheric mantle interactions, magmatic events, thermal structure of the crust and hence brittle upper crust-ductile lower crust transition zone. In capturing the estimates of the bottom of the deepest magnetic layer (Elitok and Dolmaz, 2008), the centroid method (Bhattacharyya and Leu, 1977;Okubo et al, 1985;Tanaka et al, 1999) was used. Moreover, the method of Okubo et al (1985) has an advantage since large grid sizes of data are not necessary, whereas other studies require large grid sizes.…”
