These Quaternary research papers summarize the recent work of Quaternary scientists working in various areas of the Yukon. They are based on studies by government geologists, graduate theses and doctoral dissertations. This volume is the first in a series of publications which will document Quaternary research being done in Yukon in fields of surficial geology, placer geology, glacial history and geomorphology.

This volume of Yukon Geology is the second of a series that reports on geology of the Yukon, especially those studies with an economic aspect. It is an outgrowth of the Yukon Exploration and Geology series, containing the material that made up the first half of the book. That material forming the second half of the book (summaries of mine production, current mineral exploration work and description of mineral showings) is now published in the Yukon Exploration series. Most of the papers in this volume represent work of geologists involved in graduate thesis work supported in varying degrees by Exploration and Geological Services Division. Other papers represent work of geologists with the Division involved in conducting economic geology investigations in Yukon, and geologists from mining companies and other government agencies. In addition, two contributions were funded by the Canada-Yukon Economic Development Agreement (EDA).

This volume follows earlier annual Mineral Industry Reports for Yukon published by the Department of Indian Affairs and Northern Development. In addition to the summaries of work by exploration companies found in those earlier publications, this volume contains reports on the geology of mineral deposits and mineral districts under active investigation by geologists of the Department. This volume further includes a set of maps showing most known mineral occurrences in relation to the mineral and placer claims in good standing with references to descriptions of each occurrence. It is intended to keep these maps up-to-date and to produce them annually as a convenient inventory of occurrences. This volume contains material for two years, effectively bringing this report series up-to-date. The new title for the report was chosen to more accurately reflect its content.

This volume contains reports describing the placer mining industry in Yukon during 1978 to 1982 and follows earlier annual Mineral Industry Reports for Yukon published by the Department of Indian and Northern Affairs, and by the Geological Survey of Canada. There are two sections in this volume. The first contains reports describing certain aspects of the placer mining industry, while the second contains maps showing the distribution of placer claims and leases, and descriptions of individual mining operations. Reports in the first section describe the placer mining industry as a whole, and outline regulations and restrictions on placer mining in Yukon. In addition, lists of references to selected creeks in Yukon are also included. Several papers describe the formation of placer deposits, and the exploration mining and marketing of placer gold. Reports in the second section describe 288 individual mining operations active in Yukon between 1978 and 1982. Information in the reports was derived from field investigations, from records on file, and some information for the years 1978 to 1979 was compiled from the field notes of Dr. D.B. Craig.

This third volume of Yukon Geology represents five years of geoscientific research sponsored and funded by Exploration and Geological Services Division (EGSD). Under the Northern Mineral Policy, Indian and Northern Affairs Canada has the responsibility to develop ad maintain the geoscientific database. In support of this policy, EGSD has assisted the authors through direct funding or by logistical support during the field season. This volume covers a wide range of topics; the majority of papers have direct implications for mineral exploration in the Yukon.
