On Pyrite And Marcasite

This book delves into the science and history behind pyrite and marcasite, two minerals often confused with each other. Stokes, an expert in mineralogy, explores the properties, uses, and cultural significance of these minerals throughout history. With detailed illustrations and photographs, this book is a must-read for anyone interested in geology, chemistry, or cultural history.

Excerpt from On Pyrite and Marcasite Sir: The subject of the secondary enrichment of ore bodies is one of the most important in chemical geology, and probably also one of the most complex, because nothing like chemical homogeneity is to be an tieipat'ed at or beneath the croppings of ore deposits. A long time must elapse before the processes involved are fairly clear. The memoir by D1. II. N. Stokes Which I transmit herewith, for publication in the Bulletin series, is 2111 important contribution to this subject, describing a method for the quantitative determination of pyrite and mareasite When in mixture, and discussing some of the relations of these most abundant sulphides to those of copper. This memoir represents only a portion of Dr. Stokes's work in this field, and it is to be expected that other papers will follow as soon as practicable.

This book deals with sedimentary sulfides which are the most abundant authigenic minerals in sediments. Special emphasis is given to the biogeochemistry that plays such a central role in the formation of sedimentary sulfides. It will be of interest to scientists in a number of disciplines, including geology, microbiology, chemistry and environmental science. The sulfur system is important to environmental scientists considering the present and future effects of pollution and anoxia. The development of the sulfur system – particularly the characteristics of ocean anoxia over the last 200 Ma – is useful in predicting the future fate of the Earth surface system as well as in understanding the past. The biochemistry and microbiology of the sulfur system are key to understanding microbial ecology and the evolution of life. First monograph on sedimentary sulfides, covering the ancient and modern sedimentary sulfide systems Comprehensive, integrating chemistry, microbiology, geology and environmental science All key references are included and discussed
