As one of the world’s oldest continents, Australia has experienced a complicated geological history and thus has a distinctive landscape and an extensively weathered topography. As such, the gravity field of Australia behaves differently to that in other countries. This paper investigates the features of the Australian gravity field. The methods used are a simple statistical comparison, Fourier...

The uppermost masses of the lithosphere notably the land topography, bathymetry and ice make a significant contribution to the gravity signal captured by ESA’s GOCE gravity mission [1,2]. This circumstance is used 1) to evaluate ESA GOCE gravity field models of all generations, 2) to evaluate various topographic data sets and 3) to compute a global Bouguer gravity anomaly map. All of the above ...

Analysis of the subsurface structure Mount Ijen, Banyuwangi was carried out based on anomaly data obtained from satellite image data. This research conducted with aim identifying structures around site. In this study, what is determined complete Bouguer (ABL), regional and residual anomalies ABL, their inversion modeling. The results representation underground bouguer values in Ijen area range ...

Low-temperature thermochronometry reveals regional Late Cenozoic denudation in Fiordland, New Zealand, consistent with geodynamic models showing uplift of the overriding plate during incipient subduction. The data show a northward progression of exhumation in response to northward migration of the initiation of subduction. The locus of most recent uplift coincides with a large positive Bouguer ...

[1] The Adare Trough, located 100 km northeast of Cape Adare, Antarctica, represents the extinct third arm of a Tertiary spreading ridge between East and West Antarctica. It is characterized by pronounced asymmetric rift flanks elevated up to over 2 km above the trough’s basement, accompanied by a large positive mantle Bouguer anomaly. On the basis of recently acquired seismic reflection and sh...

Generalized Derivative Operator (GDO) is one of the first-order derivative filters that could control derivative’s direction by modifying value azimuth () and dip parameters. This study aims to examine those GDO parameters on synthetic Bouguer anomaly apply them field data Silver Peak geothermal identify geological structures. We use Python programs conduct other operators such as horizontal gr...

geophysical data are always affected by different sources of anomaly. these sources are classified in to three groups: first group is relatively deep sources commonly called as regional effects, second group is near surface sources or local effects and third group is high frequency noises. the only common way to separate the anomaly is separation with respect to the signal frequency. there are ...

In this work, we present new Bouguer and residual anomaly maps of the Central Pyrenees calculated from 3590 stations, which 1141 are observations acquired surveys performed between 2018 2019. The most prominent feature is long wavelength elongated minimum in its central part that continues to W ends towards E with a positive gradient seems envelope minimum. Other short medium minima superimpose...
