""The Gold Deposits in Australia: Their Discovery, Development, and Geognosy; with a Disquisition on the Origin of Gold in Placer-Deposits"" by Davison Simpson is a comprehensive guide to the history, science, and geology of gold deposits in Australia. The book explores the discovery and development of gold deposits in Australia, as well as the geognosy (the study of the earth's structure) of these deposits. The book also includes a disquisition (a formal discussion) on the origin of gold in placer-deposits, which are deposits of minerals that have been concentrated by the action of flowing water. The author discusses the theories of how gold is formed in these deposits and the processes that lead to its concentration.The book is written in a technical style, with detailed descriptions of geological processes and scientific terminology. However, it also includes illustrations and diagrams to help readers understand the concepts discussed.Overall, ""The Gold Deposits in Australia"" is a valuable resource for anyone interested in the history, science, and geology of gold deposits, particularly in Australia. It provides a thorough exploration of the topic and is an essential reference for anyone studying or working in the field.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
