Silica sand deposits in the Monrovia area, Liberia

Thin surficial deposits of white silica sand occupy much of the flat coastal area of Liberia from Monrovia to Buchanan 100 km southeast; most of the sand is of good quality for glass manufacture. A lagoonal mode of origin is suggested for these essentially monomineralic deposits. Based on the average thickness of one meter and a conservative bulk density of 1.6, the easily accessible deposts along the Freeway, the Kakata highway, and the Schieffelin road cover about 68 square kilometers and contain at least 109 million metric tons of silica sand.
