Introduction to this special section: Gravity and potential fields 7 Aug 2013 | 12:09 am

Tien Grauch and her coauthors describe an integrated study of high-resolution aeromagnetics, ground gravity, airborne gravity gradiometry, TEM, and 2D seismic data for imaging not only basement faulti...

Advancements in understanding the aeromagnetic expressions of basin-margin faults--An example from San Luis Basin, Colorado 7 Aug 2013 | 12:09 am

Advancements in aeromagnetic acquisition technology over the past few decades have led to greater resolution of shallow geologic sources with low magnetization, such as intrasedimentary faults and pal...

Toward 1-mGal accuracy in global marine gravity from CryoSat-2, Envisat, and Jason-1 7 Aug 2013 | 12:09 am

More than 60% of the Earth's land and shallow marine areas are covered by > 2 km of sediments and sedimentary rocks, with the thickest accumulations on rifted continental margins (Figure 1). Free-air ...

Advancements in satellite gravity gradient data for crustal studies 7 Aug 2013 | 12:09 am

In recent years, global gravity models, both based only on satellite data and from combination with terrestrial data, are increasingly available and particularly useful to construct regional models be...

Performance of airborne gravity gradiometers 7 Aug 2013 | 12:09 am

Airborne gravity gradiometry (AGG) is becoming a widely accepted tool in exploration. It provides rapid acquisition of accurate gravity data at high spatial resolution with complete coverage over larg...

Expression of terrain and surface geology in high-resolution helicopter-borne gravity gradient (AGG) data: Examples from Great Sand Dunes National Par... 7 Aug 2013 | 12:09 am

Airborne gravity gradient (AGG) data are rapidly becoming standard components of geophysical mapping programs because of their advantages in cost, access, and resolution over measurements of the gravi...

Consequences of flight height and line spacing on airborne (helicopter) gravity gradient resolution in the Great Sand Dunes National Park and Preserve... 7 Aug 2013 | 12:09 am

Line spacing and flight height are critical parameters in airborne gravity gradient surveys; the optimal trade-off between survey costs and desired resolution, however, is different for every situatio...

Analysis and reprocessing of airborne gravity gradiometer data over the Strange Lake rare Earth deposit, Quebec-Labrador 7 Aug 2013 | 12:09 am

A high-resolution airborne gravity gradiometer survey was flown in March 2012 over the Strange Lake intrusive complex, located on the border of Qu├ębec and Newfoundland and Labrador. This survey provid...

New INTERPRETATION journal result of cooperative efforts 7 Aug 2013 | 12:09 am

The inaugural issue of I nterpretation , a new journal jointly published by SEG and AAPG, has been completed and will be mailed free of charge to print recipients of Explorer and The Leading Edge in e...

Mathematica strat column 7 Aug 2013 | 12:09 am

In my new life as the only geophysicist in a geology/geography department, one of my first jobs is to figure out the local stratigraphy. These are the rocks we plan to investigate by outcrop and near-...
