Description

Karst Bauxites: Bauxite Deposits on Carbonate Rocks presents a comparison of bauxite regions using mathematical statistics methods. This book is divided into eight chapters that highlight the quantitative processing and assessment of the information available for bauxites.

The opening chapters present observational and analytical evidence concerning karst bauxite, with particular emphasis on Hungarian bauxite deposits. The typical features of bauxites are analyzed from a variety of aspects and results from different bauxite regions are compared. Other chapters consider the feature of metamorphosed karst bauxites. The remaining chapters discuss the conditions of formation of karst bauxites and with the factors controlling their geographic and stratigraphic distribution.

This book will prove useful to geologists, mineralogists, and researchers.
