A 1960 report on the Nevada granite (Izett, USGS) is posted on the internet but the very small numbers there are hard to understand. [81] Robertson says that Rockport-1 has 25% Quartz and Rockport-2 has 33% Quartz and he usually talks in volume percent. Robertson page 35.

Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO. This colourless solid is an electrical insulator with a higher thermal conductivity than any other non-metal except diamond, and exceeds that of most metals. [12] As an amorphous solid, beryllium oxide is white.
The general population is unlikely to develop acute or chronic beryllium disease because ambient air levels of beryllium are normally very low (<0.03 ng/m 3). [39] However, a study found 1% of people living within 3/4 of a mile of a beryllium plant in Lorain, Ohio, had berylliosis after exposure to concentrations estimated to be less than 1 ...
