The Mineral Exhalation Theory of Metallogenesis in Pre-Modern Mineral Science

  title={The Mineral Exhalation Theory of Metallogenesis in Pre-Modern Mineral Science},
  author={J. Norris},
  pages={43 - 65}
Abstract This paper explores the theory of metal generation through mineral exhalations, and its connection to the view of metals as composite substances. In Aristotle's theory, the vapour stage was important for allowing the elemental mixing necessary for generating composite yet homogeneous metallic matter. The idea of exhalations was variously incorporated with the Sulfur–Mercury theory of metal composition by medieval Arab authors, and the diversity of ways in which these ideas were… Expand

Early Theories of Aqueous Mineral Genesis in the Sixteenth Century
Abstract The generation of minerals is recognised as one of the most important issues of premodern chemical science. While stony minerals and gems were believed to have origins associated with waterExpand
The genesis and growth of minerals, as well as the existence in ore veins of such organic features as ‘seeds’, ‘matrices’, and ‘nourishment’, remained central and recurrent issues for naturalExpand

Martin Lister (1639–1712) and Fools' Gold
It is illustrated that Lister made use of his interests in natural history to go one step beyond them, postulating that the sulfurous exhalations from pyrites were responsible for the heating of hot springs, as well as meteorological and geological effects. Expand
