From introduction: The purpose of this study was to investigate the quantity and quality of [Central Ceara, Brazil] magnesite, and the writer concludes that this group of deposits constitutes one of the major reserves of high-grade magnesite in the Western Hemisphere. The ore could be used in the production of any commercial grade of magnesia with little or no beneficiation. Soil and alluvial overburden is thin between widespread outcrops, so all the deposits could be mined from open pits.

This booklet is the fifth chapter of a training course developed for Air Force Reserve personnel about the Cold War's impact on world affairs. This chapter "is intended to show how the Communists have attempted to subvert the Latin American nations as a step toward the avowed Communist goal of world domination, and to show how the United States and other American Republics are meeting the perilous Communist threat" (p. 1). This booklet includes background information, analysis, review questions, and a list of readings for further study.
