Интересы экономики все больше требуют от человечества овладения* богатствами морей и океанов. Автор член-корреспондент АН Латв. ССР рассказывает о том, как планируется изучение и освоение дна океанов и морей, какие перспективы открываем перед человечеством это направление геологии.

Брошюра рассказывает о роли Совета Экономической Взаимопомощи в развитии сырьевых ресурсов стран — членов СЭВ. Приводится краткая характеристика геологического строения территорий стран, входящих в СЭВ, а также данные о минеральных ресурсах этих стран.
Брошюра рассчитана на широкие круги читателей, она будет полезна лекторам как научно-популярное пособие к лекциям о странах — членах СЭВ, о развитии их экономики.

Every day, somewhere in the world, decisions are made about how public lands that might contain undiscovered resources should be used or whether to invest in exploration for minerals. Less frequently, decisions are made concerning mineral resource adequacy, national policy, and regional development. Naturally, the people making the decisions would like to know the exact consequences of the decisions before the decisions are made. Unfortunately, it is not possible to inform these decision-makers, with any certainty, about amounts, discoverability, or economics of undiscovered mineral resources.

Mineralogy deals with the predominantly crystalline building blocks of the geologi-cal matter surrounding us, the minerals. Since this geological matter served as a natural environment for humans from the beginning of their existence as a habitat and source of raw materials, the study of minerals as raw materials, building materials, materials and jewelry has always been a vital necessity. Mineralogy from this point of view is one of the oldest sciences. The increasing production and use of technical materials led to the fact that the concept of minerals today has also been extended to synthetic products <...>

Geology of Australian and Papua New Guinean Mineral Deposits heralds a new era in  the publication of The AusIMM Monograph Series. The new methodology involves a small Committee, including a Project Coordinator. It has proved most effective and economical.

The Monograph 22 Committee was established early in 1996, under the direction of Sandra Close, (Chairman of The AusIMM Publications Committee) with the Joint Editors, The AusIMM Publications Manager and the Project Coordinator. Overall parameters and criteria for papers were determined and a detailed Guide to Authors and Standard Operating Procedures were developed, to ensure a streamlined process. Over 300 companies were then invited to submit papers if their deposits met the criteria. The invitation was repeated in The AusIMM Bulletin and The Australian Geologist, to ensure that the volume’s coverage was comprehensive.

Ore deposit geology may be taught late in a student’s undergraduate programme, or even at the beginning of a graduate programme. At this stage the student is able to link many of the concepts involved in ore genesis into his or her knowledge of the building blocks of the geosciences. Or it may be taught early, to show students potential applications of their emerging knowledge. This book is designed for the former case and also to be a reference if a student chooses to work professionally in the field. Knowledge typical of standard undergraduate courses in mineralogy, igneous, metamorphic and sedimentary geology, structural geology and tectonics, and geomorphology are assumed, together with some basic chemistry. It is not assumed that students have had courses in isotope geochemistry or in geochemical thermodynamics. <...>
