Historic collection of 1,974 miscellaneous rock samples collected by C.R. Lindsey. Consists of rock samples as well as paper registration documents: catalogue, index and seven note books.

Rocks, thin sections and paper registers: samples from past BGS surveys and projects overseas. Though neglected for several years, the collection has been re-opened for addition of new material from overseas projects and donations. Paper registers are arranged by accession order on a country by country basis. The records have not been placed in electronic format and are not currently machine readable.
