Geology and Mineralogy of the Wellington Mine, Breckenridge, Summit County, Colorado

Submitted in partial fulfillment of the requirements for the degree of Master of ArtsIncludes oversized supplementary maps and a graphText from page 3: This paper is based on work done during the summer of 1915, while the writer was a member of a field party, engaged in geological work in the vicinity of Breckenridge, Colorado. Through the kindness of Mr. R. M. Henderson, manager of the Wellington Mines Company's property, permission was secured to examine the underground workings of the Wellington mine, the most important zinc-lead mine in the Breckenridge district. Plans showing the location of the principal drifts and stopes were furnished by Mr. Henderson, and, with these maps as guides, the writer made quite a thorough survey of the workings, determining, as far as possible, the geology and mineralogy of the mine. Many specimens of the country rock and the minerals were secured, and intensive study was made of them in the laboratory during the past winter
