Titanium deposits in alkalic igneous rocks
Norman Herz
1975, Open-File Report 75-35
Many types of alkalic rocks are enriched in Ti02 relative to the average for the crust. Silicate minerals in these rocks may have high Ti02 contents, but the oxides ilmenite, rutile, brookite, and perovskite are also characteristic primary phases. These tend to be higher in niobium than are the same...
Gravity and magnetic studies of The Geysers-Clear Lake geothermal region, California
William F. Isherwood
1975, Open-File Report 75-368
In order to explore for economic steam reservoirs, it is important to know the complete, three-dimensional geology which governs such a system. The Geysers-Clear Lake region California (figure 1), has the world's largest production of commercial power from a dry steam geothermal reservoir. This paper describes gravity and magnetic field...
Origin and age of postglacial deposits and assessment of potential hazards from future eruptions of Mount Baker, Washington
Jack H. Hyde, Dwight Raymond Crandell
1975, Open-File Report 75-286
Eruptions and other geologic processes at Mount Baker during the last 10,000 years have repeatedly affected adjacent areas, and especially the valleys that head at the volcano. Most mudflows from the volcano were caused by massive avalanches of volcanic rock that had been partly altered to clay by steam and...
