Ore Minerals
On This Day (14th Feb 1860): Waldemar Lindgren born
Swedish-born American economic geologist who was a leader in the science of ore deposition and the use of the petrographic microscope. He helped establish that veins of metal and similar deposits are created by hot solutions derived from molten rock below, not by water seepage from above. His interest in geology began as a youth from reading a book on mineralogy and a visit at the age of 10 to the west coast of Sweden where rocks are beautifully exposed. By the time he was 17 he had seen the mines of central Sweden and the famous old silver workings of Kongsberg in Norway. As a young mining geologist, he emigrated to America in Jun 1883, drawn by the rapidly growing mining industry of the Western United States.Recent Articles
