Case Histories

Example 1: The Sierra Nevada

The next several slides show a detailed example of processing gravity data from the Eastern Sierra Nevada (near Yosemite and Mono Lake).

Microgravity

Microgravity map of St. Venceslas Church in Tovacov, Czech republic showing marked anomalies over previously unknown crypts.

A micro-gravity survey within a deep coal mine as measured along a drift cut over a pump room and other known cavities.

(A)shows observed residual gravity profiles;

(B) observed and computed vertical gravity gradients;

(C) observed horizontal gradient and

(D) underground positions of known cavities from mine plans.

The top plot shows a residual gravity profile across infilled sandstone quarries in Newcastle-upon-Tyne.

The cross-section is in the middle.
