By A. R. & Boulton, A. J. [Eds]. Katritzky

(from preface)Volume thirteen of this serial booklet contains six chapters of which 4 care for basic bills of compound periods: 1-azirines (F. W. Fowler), phenanthridincs (B. R. T. Keene and P. Tissington), tri-thiapentalenes (N. Lozac'h), and heterocyclic fcrrocenes (F. D. Popp and E. B. Moynahan). the opposite chapters are excited by specific points of the chemistry of teams of heterocycles: the tautomerism of purines (B. Pullman and A. Pullman) and quantitative elements of the electrophilic substitution reactions of five-membercd earrings (G. Marino).

Geochemical and Tectonic Evolution of Arc-Backarc Hydrothermal Systems: Implication for the Origin of Kuroko and Epithermal Vein-Type Mineralizations and the Global Geochemical Cycle

Many Neogene hydrothermal ore deposits were shaped on and close to the japanese islands from the center Miocene to the current day and this day many subaerial and submarine lively geothermal platforms are energetic. This booklet summarizes the geochemical and tectonic good points, and the evolution of varied varieties of ore deposits and present island arc and backarc hydrothermal platforms in Japan beginning with the Mesozoic
