Frederick B. Henderson, III, Geosat Committee TWO dipole-dipole CR lines were run across the known contamination plume using a PDP-8 truck-mounted computer In May 1976. While work over the abandoned brine pit and center of the plume commending the excellence of the Landsat program, the was done using an n-spacing of 100 ft. The two n-spacings were used to use planning, and hydrology. Although the workshop identified investigate which spacing would be better for future work; some significant values for the use of MSS data in initial work was planned with the intention of using this geophysical applications, including greater synoptic perspective study as a prototype for actual monitoring of other sites in and rapid global coverage, it was felt that there the future where only limited amounts of geohydrologic data were several improvements that could be made. The workshop would be available.

Corrected industry in the mid 197Os, the mining industry has been data are generally output onto a small thermal printer; quick to make use of this technology, as microprocessing data can then be transferred by hand onto a field map.

There are many such instances to Japan's cities (soft and unconsolidated with highly be found in the ground under Japan's cities, in which the irregular strata) are taken into consideration, the best way of surface layer shows greater S-wave velocity values than investigating this ground appears to be by reflection prospecting underlying layers due to soil improvement measures that using SH waves, with their sensitivity to irregularities have been taken. This is another reason why it is advantageous in ground structure and short wavelength, which gives to use SH waves in reflection prospecting.

Nicoletis, Total CFP; and J. P. Walch, L.G.I., France In the past few years, induced-polarization has been tentatively used by the petroleum industry as a tool for detection of geochemical anomalies created by the presence of hydrocarbons at depth (see. Various techniques, generally duplicated from the mining industry, have been tried in both frequency and time domains. Curiously enough, interpretation and modelization of the polarization phenomenon were essentially undertaken in frequency domain to the prejudice of time domain. Consequently, in order to interpret the time-domain IP data collected with CGG's Transiel equipment and considering the lack of interpretive tools, we set up a procedure which compares recorded data to a series of numerical simulations Figure 1. Hypothetical model used for the inversion of real of simple physical models until a sufficient likelihood is data.

Northeastern Florida studies Titanium is abundant in the earth's crust, but the metal Field studies were made at several operating mines in can be extracted economically only from a limited group of northeastern Florida. The examples reported here are from a titanium-bearing minerals, chiefly rutile, ilmenite, and Pleistocene dune deposit having fairly sharply defined edges weathered ilmenite. Placer deposits of heavy minerals yield and a depth extent of 8-21 m. The heavy minerals make up about half of the world's production of titanium, including about 4 percent of the deposit, and are disseminated in nearly all of its rutile (U.S. Bureau of Mines, 1982). These crossbedded sands which appear to be fossil dunes overlain placer deposits are mined in many parts of the world, unconformably by horizontally bedded, unmineralized including Australia, India, Sri Lanka, and the southeastern sands.

The sudden, positive deviation from the expected microprocessor-controlled magnetometer located on the sea pore fluid resistivity trend occurring at a depth of 1800 ft is floor. Some recent field measurements occur at this depth.
