The Geology of Jamaica is formed of rocks of Cretaceous to Neogene age. The basement consists of Cretaceous island arc and back-arc basin sequences that formed above a subduction zone. The cover is of mainly Eocene to Miocene shallow water limestones, that have been uplifted due to the presence of a restraining bend along the major strike-slip ...
By December 1896, 1500 people were living and working there and several new mines had been dug around the Yellow Aster claim. By the end of 1897, more than $600,000 (equivalent to $21,974,400 in 2023) of gold had been produced in the Rand Mining District, mostly from Yellow Aster.
Bauxite with US penny for comparison. QEMSCAN mineral maps of bauxite ore-forming pisoliths. Bauxite (/ ˈbɔːksaɪt /) is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al (OH)3), boehmite (γ-AlO (OH)) and ...
Silver mining began in 1879 at the Einstein mine, nine miles northwest of Fredericktown in Madison County. The settlement of Silver Mine, complete with US Post Office was established to serve the miners of the Einstein, Ozark, and Apex mines.
